All, I have a 02 S3T. I added the Race ECM, K&N filter, the SuperTrapp exhaust running 21 disc. I am at Sea Level. The bike starts a bit hard... sparks up but then won't idle. I have to give it a bit of gas at first then she is good to go. I run 92 octane super gas. Overall the bike seems to run just a bit rich. It pulls well, but seem to flatten out just before redline... 6250rpm's or so. It will pull to redline, but power is pretty much done by 6500rpm. I know that I could/should get ECU spy, but in reality, knowing me I could see me frying my ECU and with the SuperTrapp it seems like I could get dialed in pretty good adjusting the disc count. Ok, so with that said: - How discs do you run? - Does going from 21 disc to 24 disc make a "real" difference? - How many discs should my bolts hold? They are pretty much at the end of the threads... would likely take 2 more, but can't recall the cut off (the number of disc the bolts will secure) between these bolts and the next longer bolts. - What octane do you find the best for your bike, 87, 89, 92? Any additives? - on a completely different note... does anyone run the zero gravity screen on their s3t? do you like it? I am currently running the stock with a laminar lip... pretty smooth... just wondering. Well, guys, thanks so much for the input. So far I love this thing. I compliments my other rides nicely... DL1000 and KLX650. Take care j | ||

I run my '99 S3 same set up, 12 discs, on 89 octane because it is too hard to find 92 consistantly around here. There's not much else that you can do but try an TPS reset. Before I did mine it didn't start real easy and I had to give a little gas at first, now it is much happier. There is a possibility of an intake leak at the manifold to head or throttle body to manifold. Those are easily checked by spraying a water mist or WD40 at those spots to see if the idle changes. Mine was missing the little boot off the bottom of the throttle body which hurt its lower rpm performance when I first bought the bike. I bought the 3" Zero Gravity because I liked the added protection. Now I switched back to the stock screen because I like the looks better. | ||

Hi, I have a 2002 S3T set up about the same. The previous owner gutted the air box, which really helps. Has stock "bread box" and filter, but internals gutted out, with air sensor mounted inside. Need to use a catch tank also. On your Supertrapp, I dont go max on discs to quite it down, and make sure your packing is good inside. I think I run about 15 discs, works well. Key: on header, install new gaskets if needed, and tighten exaust nuts just enough to hold snug, and use a bit of lock-tite. Dont over tighten and stress them out. Make sure exaust is free of stress points in the mounts, and hangs well. Did 3,000 miles with that set up, no problem. The Race ECM, pipe, and air box mods work excellent, good luck with your setup. I run the 3" over screen, really helps with comfort. Christian | ||

I have a '99S3T which I installed a Zero Gravity shield plus a Laminar Lip! Kinda like belt and suspenders. I say it works pretty well - but I have nothing to compare it to, except a short ride with a Gustaffson which came on the bike. I got this Buell in Dec, and my first time out rode two 500+ mile days 4/3 & 6/08. Cleveland to Charlotte round trip. Other than being colder and damper than I wanted, I felt good. I noticed wind on my sholders, but not my head. My face shield stayed pretty dry also. I did a little heat gun work on the Laminar to spread it, and to fit nice with a ~ 5/8" gap above the Zero Gravity. Also drilled 2 holes in the fairing and shields for added well nuts. I had planned to experiment, but this combo works so well, I'll keep it as it is. It doesn't look too bad, but if doing it over I would have ordered a clear Laminar rather than a tinted one - as my Zero gravity is tinted also - | ||

Not sure if you're bike is running rich or not Jack. My bike is setup just like yours, except I went back to the stock airbox and a paper filter. (Prior owner had the air box gutted and I reverted while diagnosing a problem - never went back). I don't know how many discs I"m running either as the trapp was on the bike when I bought it and I've never counted. I rarely wring my bike out to redline - certainly not often enough to notice any flattening of the power curve. My bike had bad intake seals that caused it to miss and hesitate, but it doesn't sound like that's your problem. Mike is right in that you might need to calibrate the Throttle position sensor. It can "drift" over time and get to be a little off. I run the highest octane I can get, and always 89 or better. There's a station in my town that sells 92 octane, non-oxygenated (no ethanol) for hotrods/bikes/snowmobiles etc. and I buy gas there whenever I can. I have the ZG screen too. It didn't help as much as I hoped and I might add a MRA VTA spoiler here soon... Good luck, post up some pics! | ||

I have a 2000 S3T as well. Smells like it running rich most of the time. Maybe it's normal, but I've only had it since September and really have nothing to compare it too. I almost always have to help it out at start up or it won't stay running. I'm not sure if this is due to the race E.C.M. or not. I occasionally get "Pops" and momentary "die outs" after a long steady speed run coming up to a stop. I put the Z.G.+3 on over the winter. It helps quite a bit, but seems to have moved the wind right across my faceshield making it noisier in my helmet. I also think it leads to a little more buffeting in cross winds. | ||

All, I think my bike is likely running spot on... I am just new to the whole Buell motor and all its gassy smells, vibes, ticks and rattles. I have a feeling the bikes natural power curve flattens out a bit towards the top of the rpm range. Prior to the top of the rpms the bike pulls like a freakin mule. This evening I was tooling around in my nieghborhood... was putting along at a 10 mph and cracked the throttle... the bike ROARED FORWARD... front tire came up and the bike launched like a rocket. In reality I am so use to getting a bike up in the rpms a bit before cranking the throttle. I have a feeling that this bike just needs to be above idle to pull and I am limiting the bikes performance by rolling up to 4000 rpms and cracking it open. When I do that the bike quickly runs up to redline before I am onto the next shift. Going forward I will just crack the sucker off idle and hold on... I think she is running just fine. In addition, I just had the TPS reset 2 weeks ago. I had put the race ECU in and the SuperTrapp on along with the K&N filter. The TPS reset did not seem to make any difference. This evening the bike started up and idled. It sure seems like it is just on the edge of dying at first, but it keep burping along and soon settles into a slow thumpy, rythmic idle. I add the Zero Gravity last night. I will ride it a bit and will likely add the Laminar onto the Zero Gravity screen and see the difference. The stock screen and the Laminar was nice. The air was smooth with zero buffetting. In closing I added flush turn signals and my saddlebags. Tomorrow my new carbon fiber AXIO tail bag should show up. Well, thanks everyone... I think I will run her for awhile... add some discs later or run without a end cap and see if that makes a difference. I think I would rather run her a bit rich than lean... Take care, Jackariah |
