620R nose requires L brackets for mounting with dzus fasteners on that. I have the brackets but haven't fought the battle of mounting yet. http://www.usa7s.net/vb/attachment.php?attachmentid=15580&stc=1

Quick update. Tried to adjust this two days ago before a track day yesterday. As soon as I tried to rotate the allen key on the FPR with the car at idle, the twisting force let the gas squirt out around the mount of the FPR (it's bolted straight to fuel rail as shown above). Tried it again and same thing happened. At the same time my wideband computer box stopped working (battery corroded off the 9v terminal). with no way to measure and a track day the next day (yesterday) and still trying to get ready for NJMP I left this alone right now and won't touch it through the week. Got some other issues to troubleshoot right now to get the car ready for next week. If the FPR leaks during operation that could also be a relevant issue to the bad MPG.

I'm going to be taking a better look at this myself. I did a through lubing of the cable yesterday and will see if that helped. Otherwise this is what I gathered on the matter

Tom, my TWM FPR is part of the fuel rail and doesn't have a vacuum line hook up? I can adjust down to ~40psi and from what I've seen so far my fuel pressure doesn't fluctuate at all. I have never diverged into fuel system in vehicles, but to make sure i understand correctly, typically fuel pumps put out constant pressure and systems like FPR adjust the pressure with vacuum or other means? ECU never controls pressure at fuel pump with different voltages for closed/open loop conditions? IE running rich or lean wouldn't be a function of ECU commands? Car is getting better mileage but feels more sluggish on the top end on the butt dyno, but we all know that measures pretty inconsistently. http://www.usa7s.net/vb/attachment.php?attachmentid=15565&stc=1 I'm still struggling to get my profile loaded to get Pectel to communicate with Descpro software properly and will keep addressing that. I'll be looking at my A/F at idle as I adjust it? I use my downstream plug past the cat I should expect to read ~.2 to ~.5 richer or leaner?

Update: Replaced the o2 and here is the latest data. City low RPM cruising 12.7 miles .493 gallons. ~25mpg All highway ~70mph average in 6spd 30 miles 1.481 gallons ~ 21mpg Average ~21mpg I think I'm in the right ballpark now?

I think you're spot on as well. One of the few reasons not to buy a 420 and buy a lesser one is finances. Minor anecdote. Coming from the bike world where people always over think their decisions on which 600 super sport to buy, there is a saying that "GSXR 750 makes the best 600 supersport" It is weight and mechanically and weight identical but makes more power when/if you want it. In the same mindset it's easy to drive a 420 like 360 but it's much harder to drive a 360 like a 420. Sidenote: I believe bucket seats are actually lower.

Minor updates Got the fuel gauge installed on the rail. Reading right around 50psi idle and while revving. From brief research seems a tiny bit high/normal, especially if I'm mapped properly for it. http://www.usa7s.net/vb/attachment.php?attachmentid=15525&stc=1 http://www.usa7s.net/vb/attachment.php?attachmentid=15526&stc=1 Picture of the coolant temp, while at operating temp. I do have a lower temp thermostat put in, maybe I should switch it. Lower temp Tstat from my understanding should really effect much other than opening sooner but my operating temp should still be the same. It has been fluctuating overall. Normally it's right around 80, has crept up a little higher and this is now unusually low http://www.usa7s.net/vb/attachment.php?attachmentid=15527&stc=1 As far as the ECU, does anybody know why I get this message? ""DESC does not have enough information to use maps currently in this ecu. If you have a different set of maps on disk, you may be able to reprogram the ecu with them. Do you want to try that"" "DESC could not find a compatible profile. To use this ECU/MAP you will need a profile for T2v1-15:TPS/MAP fuel TPS lgn" I do have a profile folder "T2 V1-15 NA" with "ADABAPAC.AAB" which I have deciphered should work for T2 and is NA profile. So far I believe my sticky throttle/hanging rev's are due to a 1 butterfly in the ITB's sticking. Testing pending.

Here is the hard start up video when warm (you can hear fan turning on, I'm at operating temp. It does start if I give it the gas while starting > throws black cloud of gas of the exhaust. Also worth noting that my temperature has been abnormally low. I'm typically a little below 80, but have been close to 60 on the recent 130 mile highway stint.

Updates: Fuel sender gasket replaced and used the forum suggested sealant. Hylomar Blue Gasket Marker. Now I can fill the tank fully again and continue testing. Data: 15 mpg city for a brief city stint, and 14 mpg for a brief highway stint. Followed up by a 19mpg 130 mile highway stint. New development > Hard start up when warm unless I give it gas AND sticky throttle cable/ITB's hanging. Gets worse when warm. A blip of the throttle fixes the hang. Checked/lubed the cable seems alright. This weekend I'll partition cable vs ITB issue by separating them and see if rev's still hang. I know that pulling on the ITB controls still had revs hanging but I can't be certain that activating that control didn't pull the cable with it and the two were partitioned that way. Also I find some very minor vertical play in one of the butterflies. Two set screws are on tight. Here is what the idle sounds like Next courses of action: Take cable out and make sure there is no hanging/isolate it/check free play. Inspect hoses see if there is any air leaking past closed throttle causing hanging revs. Find out what IACV setup I have and whether I have TPS > check their operation. Look into the play in the butterfly and see if it's causing the issue and maybe hanging causing air to sneak past it. Side note: If you're ever concerned with lack of heat in the car, take out the 6 screws holding the pedal box cover plate on. Lack of heat will not be a concern anymore. Been driving around without it while troubleshooting and it gets HOT. Pending: New o2 has arrived and will be replaced. Adapter for fuel pressure gauge/tester is on the way.

Unfortunately it's not quite all that simple or otherwise courts and supreme Court wouldn't struggle and debate with this over the years. Pretty much all Constitutional wording has been open to interpretation of intent. Justified or not. Just look at how 2nd amendment has been executed and enforced over the years. Here is a good breakdown of rulings over freedom of speech that set precedent https://www.uscourts.gov/about-federal-courts/educational-resources/about-educational-outreach/activity-resources/what-does

Your point is correct but it's also irrelevant when it's not enforced or understood by the general public. It's sort of like speed limit enforcement. Everybody has their own understanding of how it works and how much you "can speed". Is it a true limit? Is it 5 over? 10 over? Go with traffic? The law has been so muddled in public opinion that even cops aren't sure how to proceed and will rarely if ever give a ticket for under 5mph (yes it does happen, yes it is legal to get a ticket for it, yes I've seen it first hand). Then the stuff goes to courts for arbitration there. If you ask the general public today, ~98% of people who follow politics at all will tell you that there has been some kind of constitutional crisis over the last ~10 years (covers all parties) but it was never enforced and nobody got "in trouble" for it in the executive branch even with blatant and documented violations. Laws and policies and rights only hold meanings when they are enforced.

Here is what I'm finding for the curious minded Take them with a grain of salt. Most are forum posts. Hard to find any direct info from Quaife. They apparently to not have a set period interval. Looks like it's a good time for me to look into inspecting and/or rebuilding mine going into next year.

I have actually have never heard of this. This is neither an easy thing to find as I've tried using obvious key words but they hit on wrong subjects/leads. Do you have any more info on the matter? I find that tidbit strange as that nearly every motorcycle is sequential and transmissions are rarely an issue even with typical type of owners who certainly don't research sequential proper shifting techniques prior to ownership of Supersports. Don't mean to steal the thread but this is relevant info to any new owner. I certainly don't slam every single gear change going light to light.

For anybody considering it and researching it, this little piece of background info will help you get less confused in Google searches. This is considered the G60 which replaced a very similar Sierra Type 9 For how annoying these can get in traffic I still can't imagine driving a 7 with a regular box.

Next time I log, I'll keep it steady, but I'm pretty sure I'll still be right around mid 12's when measured after the cat. I might be able to log using the offload tool at same time too. Thank you for explaining it. Here are some pictures of the bungs/o2 http://www.usa7s.net/vb/attachment.php?attachmentid=15477&stc=1 http://www.usa7s.net/vb/attachment.php?attachmentid=15478&stc=1

Here is the current update, weather and life events haven't been cooperating too much. Open issues: Fuel pressure test - I have AN lines and no schrader valve nipple on the FPR, so I have to order some kind of AN T fitting and make it work. At this time not done. New OBD2 - will be ordered today. Pending items New gasket on the way for my fuel sender. Notes: I still have hard startup and it does smell rich Start up video. Yesterday I actually had to start it 3 or 4 times while hot and it would gurgle and die. Had to get on the throttle on the 4th time to make sure it started. Complete: Software is operational. After battling for hours with 3 laptops I finally got things to communicate. I realized that PiToolBox is not a piece of software that I need. Descpro is up - stopped me with these messages http://www.usa7s.net/vb/attachment.php?attachmentid=15474&stc=1 http://www.usa7s.net/vb/attachment.php?attachmentid=15475&stc=1 ToolBox is up http://www.usa7s.net/vb/attachment.php?attachmentid=15476&stc=1

Some new parts finally arrived. Adding lightness! (to my wallet..) http://www.usa7s.net/vb/attachment.php?attachmentid=15473&stc=1 New style cage with sloped vertical bars, 620 R nose, all styles of front grills (going with black mesh right now), half doors, new belts to be in spec for track days, tons of other small misc bits and pieces. Replacement windshield sadly did not survive the trip.

I'll be the oddball Not registered, hotel not booked, tow vehicle pending, car still in progress. New seatbelts came in this week with the extra 2 points, will take time to install. Arm restraints have arrived as well. Fuel sender gasket is still in the transport webbing somewhere. Alignment is pending weather clearing up (should I go neg 2 degree like John B or just standard OEM specs?) etc etc.

Not exactly, it's a little deceiving the way eBay does it http://www.usa7s.net/vb/attachment.php?attachmentid=15439&stc=1

It was a spur of the moment adventure about 8 years ago now and I was very glad I did it. The last space shuttle was taking off (Atlantis in 2011 - STS135) so I packed up and took off with only that mission in mind. I've never left North East prior to that. It was well worth it http://www.usa7s.net/vb/attachment.php?attachmentid=15394&stc=1 After that I thought to myself "I'm already here, when's the next time I'll be this close to Miami to check it out?" A few hours later when I'm in Miami I had a thought "I'm already here, when's the next time I'll be this close to Key West check it out" After many hours of riding and enjoying Key West catch of the day I started my voyage back. Naturally since I was in a near vicinity of Tail of the Dragon I had a though "It's not too far away, when's the next time I'll have a chance to ride it?" So naturally I took that detour. IIRC it was around 3600 miles over about 6 days with 3 of those nights spend in actual beds.

I've made the trip twice so far from NY Once on my bike on the back leg of me riding up from Key West. It happened to be late at night and I was solo on a twisty road with no service after already putting on ~2600 miles. I didn't push it but I certainly enjoyed it http://www.usa7s.net/vb/attachment.php?attachmentid=15392&stc=1 Second time was in a Nissan Versa (6spd) out of all things. Friend had a wedding in Asheville and it was one of those "when in town..." scenarios. It was a fun compare and contrast after the bike trip. http://www.usa7s.net/vb/attachment.php?attachmentid=15393&stc=1 Look forward to being there in the 7 one day.

Shot gasket and leak http://www.usa7s.net/vb/attachment.php?attachmentid=15377&stc=1 Just noticed the ominous "20/12" on the tank? http://www.usa7s.net/vb/attachment.php?attachmentid=15378&stc=1 Constant throttle (12.9) http://www.usa7s.net/vb/attachment.php?attachmentid=15379&stc=1 Idle warm (11.8) http://www.usa7s.net/vb/attachment.php?attachmentid=15380&stc=1

Tested the gaskets by filling it up with the honey comb up. Problems as follows: 1) Gas poured out of the "sealed" hose that you can see in the previous pictures going to center tank (still not sure of it's purpose) that I left in the down facing position. Fixed that by pointing it back up and tightening the screw further 2) Gas poured out of the fuel sender gasket confirming that it's pretty much destroyed. Will look into options of cutting my own replacement out of finding a similar stock replacement. 4 On the way there drove with the Wideband in place. Got average of 12 or so under constant cruising load, down to 10 or even 9 on closed throttle and into 13's barely 14's under acceleration. I recorded sessions but this was a brief run to gas station and back and I havent looked into ways of offloading it just yet. I'm working for the next few days and I'll have time to give the car more attention in the second half of the week. The car did get upto temp. About 12 miles total run.
