You guys i feel like a horses butoot. I ended up pinching my kill switch wire when i moved my bar mounts to the upper spot in the clamp. just took a long time to have it ground out lol im a idiot !!! thanks for the replies though.

something about the angle censer and oil pressure. but the angle censer is in the ecu and everything with the oil checks out. we also checked fuel pressure it was 100% OKAY

Okay so new spark plug, put a new ecu in it from a new bike at the shop leak by test cleared #30 code off of ydc now is getting worse blowing smoke on deceleration when revving, also changed oil and made sure the screen was clear. The intake is clean everything is still good. when i seat bounce it acts like whaaaa bbbooggggg! then whaa it picks back up any help please???

Thanks Miley I will do that tomorrow in the shop. I will post results. These forums are so helpful huh 🙂

It straight bogs if I hit a g out while giving it a handful of throttle. But only for a second. Then at high speed it does it. My bike has 70 hrs on it any ideas I was going to start with the basics and do a plug clean tank and put the one air filter back in

clean them already!! lol

Did you clean off that sensor and your air box yet?

Yes thats the one. Clean it and disconnect it that should fix the problem. If not i have no idea. My friends bike was doing the same thing he thought maybe it was his wire harness and took everything apart which didnt fix anything. Then he brought it in to our shop to have the tech look at it. This is what he did and she was running great in no time.

Clean your air flow sensor in the bottom of the air box. It might be covered in filter oil. My friend had an issue that sounds like that, and thats what it was

Hi There, This is my first post to Thumper Talk. I Have a 2015 YZ450 with about 60 hrs on her. It seems to me that i'm always the one who looses coolant on the rides we go on. Really only in the slow rocky stuff but after a long ride i look in the radiator and i usually can see my fins. I have ran the O.E.M. Yamaha coolant as well as engine ice. To me its weird how the Y pipe hose comes down and is so close to the the header on this bike. I have been thinking about wrapping my header any thoughts? Oh yeah i live in the high desert of Colorado. Do all types of riding. I've also thought of converting over to Evans coolant any ideas? Thanks guys
