Yesterday my brother and a buddy were out riding and i tried starting the raptor after a break and it backfired and blew the cargb boots off both front sides of the carbs. I didnt have the tools on the trails, so after towing it home i inspected the boots and when they blew, they ripped both boots apart.

I need 2 new front boots, i like the UPP Racing ones, but i dont know about the clamp set up or if these are even neccesary.
Any 01 owners have any ideas or ways to fix this from happening again to me. Ive heard to use hose clapms, zip ties, yamah clamps, but i dont know whats best. The yamaha clamps suck i think, so please lead me in the right direction here.

Thanks, Gwinnwarrior

 

please dont just post telling me to do a search either, i did it and found 6 topics with not many replies.

thanks

 

Well, the 02+ Intake boots are made of a solider rubber. I got the 02 update, my dealer did it for free, but i to ripped one of my boots when i stalled it once, the right one so i have it superglued... actually, ive had it superglued for about a month now. .. might want to get that fixed. hm.

 

I don't mean to steal your thread warrior but is there a better way to keep the boots on the carbs?

 

Best way not to blow the boots off is, never blip the throttle when starting, I've blown mine off 4 times, simply by blipping the throttle and hitting the starter. If you're blowing them off starting the quad, this should solve your problem. Another solution is to go up one size on the pilot jet, introduces more fuel during the starting process. My boots have never torn, and the UPP Boots will blow off also, seen it happen.

 

if you use hose clamps dont overtighten them they will rip the boots too

 

what about raising the idle?

i did blip the throttle while it was starting and im sure thats what happened.

thanks guys for the responses, im not using hose clamps im going to use the stock yamaha ones again.

 

upp racing has nice carb boots for your carb. I have some and have not had any problems. uppracing.com

 

I had the same problem with my raptor so I went up 1 size on the pilot jets.Stock is 22.5 so get 25,s then I grinded the metal spacer on the carb clamps.No problems after I did this.
