13HemiRam Posted January 20, 2017 Report Share Posted January 20, 2017 So this happened today... It appears that a piece of the spring broke off and got wedged inside the throttle housing. I was half way up a hill in 2nd gear when she stuck wide open. I didn't have much time to think because the front end was coming up, the top of the hill was getting closer and there wasn't but about 20 yards til I went back off the other side of the hill. So I grabbed the clutch and both brakes and after what seemed like 2 minutes of fighting it she finally bounced to a stop. I reached for the key to shut it off but not until she free revved for maybe 3-6 seconds. It was the fastest I've ever heard anything rev and I'm honestly surprised it didn't come apart. It was loud and just about rattled my teeth out from the vibration. My ears were ringing after I shut it off and the guys I was riding with said it was very loud from about 100 yards away. I should have just reached for the key in the first place but I panicked a little. It was fine to ride home and still ripped hard but I hope I didn't do too much damage. It only has 5-6 hours on a brand new motor top and bottom Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Motooutcastxxx Posted January 20, 2017 Report Share Posted January 20, 2017 No offense but holy shit, have you ever taken that cover off? When it was down for the rebuild you probably should've lubed everything up too! Whatever is going on there, replace all of those parts in that pic, they're all pretty cheap, or better yet get a whole new thumb throttle. I wouldn't even ride a quad with the inside of a thumb throttle, including the cable looking like that. 1 Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted January 20, 2017 Report Share Posted January 20, 2017 2 strokes are ment to rev the piss out of them. All you had to do was slame on the brakes in gear till it died in a higher gear would be easier. 1 Quote Link to comment Share on other sites More sharing options...

Never even thought to look inside there. Going to pick up a nice used one tomorrow Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

13HemiRam Posted January 21, 2017 Author Report Share Posted January 21, 2017 Honda throttle ftw From a 450? I think I might still have one laying around from my Honda 450 days Quote Link to comment Share on other sites More sharing options...
camp0429 Posted January 21, 2017 Report Share Posted January 21, 2017 Not sure about the 450's but most all Honda throttles, utility or sport quad are the same. Do a little search on it, it's a much better throttle than Yamaha. You can find them pretty cheap. Quote Link to comment Share on other sites More sharing options...

LukeSandiefer Posted May 8, 2017 Report Share Posted May 8, 2017 The 400ex throttle works great. Easy installation too. Quote Link to comment Share on other sites More sharing options...
