Me and my cousin were out riding this weekend, he has an 07' GYTR Raptor, it ran fine all day then when he was putting it away it died on him and the only way we could get it to start is if we gave it gas and as soon as you let off it dies. Thought it might be bad gas but we drained the tank and put new gas in and it still acts the same. Has anyone had this problem, or have any suggestions?

 

Sounds like it could be the TPS (throttle position sensor) it has been known to be bad on a few raptors.

Is it stock or has he added mods?

If added mods did he add a FI controller?

 

No mods it's stock.

 

same prob with my 07 gytr .... changed the spark plug and now works like new! hope u get it fixed
