Have a couple of issues currently and looking for some insight. Last year bike was in shop for stator and throwing codes nonstop. All different sensor codes but non persistent all became historical. This year first ride out i noticed it threw a code and then i lost speed and gear (speed sensor) in the IC. However it also fell flat on its face accelerating in first gear from 6000-7000 rpm. To the point it felt like brakes were applied. It then would surge like crazy when you backed off to 3-4k rpm. Engine light would then come on and stay on for duration of ride even if the issue seemed to go away. Any ideas on what to look for first? | ||

TPS reset and post the codes historic and active | ||

Okay. Reset TPS and see from there the codes not nearly as helpful as i'd hoped :-( | ||

Only think i can think of is Speed sensor is bad or loose. Falling on its face maybe the whole O2 sensor issue. Maybe it doesnt know if what gear its in when the speed sensor is bad? Oh Well appointments for the end may with dealer. | ||

none of those codes should cause the falling flat symptom you're describing. I have a faulty VSS and have had bad O2's at the same time never had that symptom. With bad O2 it'll just go into open loop mode and the VSS going out doesn't apply here either. The TPS reset you can do from home without software or cables. if you'll to a search on the board for TPS reset there is a step by step guide. Def want to get the other two looked into for sure. Chances are a new VSS and pair of O2's will resolve the reasons the codes are set. Even a not so handy person can change all three sensors out in case you're out of warranty | ||

Bike been de-noided? Might be the surge issue. | ||

> Maybe it doesnt know if what gear its in when the speed sensor is bad? the bike doesn't have a sensor to tell it what gear the transmission is in. it has to calculate what gear it's in based upon the output of VSS and CKP. | ||

bike isnt de-noided This is why im wondering if the flat spot is a result of the VSS being dead the ecm is confused as to the gear and shuts down me winding her out. (Message edited by ratgin on May 17, 2012) | ||

check your sensors, connections, grounds. | ||

Yea been there done that.. After the stator failed spectacularly last year,, think heavy smoke wafting up between ones legs, bike feeling like its on fire.. it started popping sensor codes non stop. Shop said they were historic so not important. Seemed to me they were a symptom of an bigger issue | ||

In their defense, the low voltage conditions from having a dead stator will cause the bike to act wonky and throw false trouble codes. If they fixed the stator, cleared the codes, and they are still occurring, then you have a legitimate issue. | ||

i don't understand -- on the one hand you're saying that you've BTDT and checked your sensors, but at the same time you're saying that you still think the VSS sensor is bad. when was the last time that you checked/replaced it? some time in the past doesn't count if you're still having problems. I'd be on the VSS and CKP and I'd still be checking wiring. | ||

Last fall i replaced stator , vr and a few odds and ends. It also spit out codes every ride. O2, low fuel pressure, another fuel type one and a few others. All were considered historic even though they happened some happened before and lots after the stator fix. When i picked it up from clutch and rear shock repair it was running like crap and they did a TPS reset. With in a week season was over and she was put to bed for the winter. This year i have ridden it 3 times. 3 codes non historic and VSS is not working. This bike hates me. I have about 5k miles on it and it lives in the shop | ||

I just rode a full track day with the speedo reading zero, it had rained when I was trailering the bike to the track and when I applied the rear brake during the first session the fuse blew, since the speed sensor gets its power from the same fuse hence zero on the speedo. No codes and didn't affect the bike at all. Popped a new fuse in and the speedo started working again so I don't think your dealer should be trusted if they are saying that the VSS was affecting the engine operation. | ||

One issue solved is all Speedo and O2 working in a couple weeks, Will see if the bike still runs poorly |
