my x1 runs poorly at moderate to wide open throttle. it stumbles. it ALWAYS has since I bought it new. I have no faith in my dealer (walters bros) they reset my TPS twice, no effect at all. where can I ship off my cantankerous POS and have it "fixed"? I have a slip on wileyco exhaust and a custom airbox. but nothing "radical". and a race ecm installed, as well I still have the stock one. I'm really sick of it. It tried to kill me yesterday by dying right after launching into traffic heading up a big hill. | ||

Have you checked for intake seal leaks? What do your plugs look like? Have you checked your AFV with ECMSpy? Make sure the vacuum port on the manifold has the plug on it still. | ||

no, ?, no plugs i have changed in past to no avail. I don't have an ecm spy. I am willing to pay someone. which is a rarity for me. mechanical problem I enjoy. air-fuell or ignition I despise looking for a shop or perhaps a "guy" who does this. it's run like this pretty much as long as I can remember. pre- new airbox, pre- slip on exhaust maybe even? I suspect crap TPS. like it's limits are set but perhaps it isnt linear. I dont know. and I dont want to know at this point. (Message edited by dsergison on March 31, 2011) | ||

You really need to read the ecu with ecm-spy,quite simple actually.It will tell you what your AFV has skewed to so you know if you are lean or rich--I am betting lean.Then find a dyno shop with someone with half a brain to run the thing.It really isnt rocket science----I am a former tube framer/carb guy and I can do it. The poor early fuel injected bikes had so little computing power there are just not enough rpm/throttle position windows to tune good. IIRC X-1 has a 3000,then 4000,then 5000 with no way to tune in between where the later bikes had LOTS more areas to work with. |
