Hi,
I have a 1994 Yamaha YFM350X Warrior. I was wondering what to put on it for more acceleration or how to tune the exaust pipe. What i have done to it to effect performance is... Carb jetting(not sure of the jets) and has a FMF Mega Max 2 Spark Arestor(with stock header) Is there any way i can get more Top End of adding aftermarket stuff or tuning my bike some how???


Thanx You,

 

put on a filter and then rejet it again should give it a lil more top end.

 

And leave the top off of the air box .. that's supposed to give good gains though I'm not sure how good. Most people here dub it "free HP"

Just how much should you expect to get on a Warrior by removing the air box lid? Curious about that .. and what do you do about the air filter securing ?? it just kinda sits in there and the lid keeps it in place ..

If someone could answer the gain question for me I'd be most appreciative [img]i/expressions/face-icon-small-smile.gif[/img]

 

Im new at all the mechanical work on atv's what is "dub it "free HP"

NO NO NO!! do not remove the air box lid on the warrior you will ruin your motor. get a pipe kit/ pipe/filter/jets work a lot better and safter.. your filter is held in with your lid. drill 1'' holes near the back of your lid. if u want to do sumitn.. chekc out albaaction.com..

 

Glad you said that 2000IA .. I thought of doing that (leaving the lid off) last weekend after i cleaned my filter, but looking at it surmised that the lid holds the filter in place .. so didn't do it. Thanks [img]i/expressions/face-icon-small-smile.gif[/img]

 

yes, if u pulled ur lid off, you would spend more money then you would gain power. you would most likey loose ur filter= meaning it would lay in the air box.. and you would suck all the dirt. and then have to bore your quad

 

I just heard from some people to get more top end i can add more dics to my fmf megamax... but it will make it louder... what they didnt kno is if it will decrese my bottom end.... does any 1 KNOW if it will???

 

you will loose a little low end but not much unless u make a big increae diffecne in discs. same way with my old supertrapp..

 

Thanks man Hopefully I wont notice the diff.. i was reccomended 12 discs and i have 9 now so not to many... lol... i am looking in to thes things for the airbox the lets air in but wont let dirt in... hopefuly it will all work out
