Props to stoops for figuring this out...

We ride with big jets at altitude and everyone in denver is lacking power but stoops has figured it out put cotton balls in your air filter and the power increases dramaticly. Same effect as putting duct tape over part of it. Try and you will be impressed!

all that does is restrict air flow, and sooner or later someone will put them in without a filter. cotton balls are not good to use in an engine. thats why filters are made from foam or paper element. cotton disintegrates. just upjet more. it gives the same effect.

.Help me understand. At high altitude there is less air pressure so it seems to me you would use smaller jets to maintain proper fuel to air ratio. Am I wrong? Jim

Re: Props to stoops for figuring this out...

That is correct. At altitude you have to down jet to reduce the fuel flow.

turbocharge them if you run at altitude.. it works for the air Force, why not the MA ;-)

Re: Props to stoops for figuring this out...

i'm wondering if adding some alcohol to gasoline will do it .. small gas tank won't require much.

The ideal straight alcohol air:fuel mix ratio is near 7:1 or so .. And straight alcohol requires much bigger mainjets.

Maybe if the right gasohol blend were found it would make up for less available oxygen at altitude (someone would need to do the math )

and since adding alcohol would raise the octane rating, compression ratio might be raised a bit to offset slightly poorer performance with the blend .. but there might be other things to consider like a high alcohol percentage blend reacting with some rubber or metal parts..

maybe adding alcohol is a way to artificially test the effects of running a smaller main jet .. leaning the mix at sea level or wherever you happen to be..

Re: Props to stoops for figuring this out...

There are two cycle go-karts the run on a gas and alcohol mix, why don't you try to find the ratio and see if it will work in this situation as well?

Re: Props to stoops for figuring this out...

Yeah, I have no idea why when I added cotton balls that it worked, but it does. It no longer dogs out. Yeah maybe Ill come up with some other option. Maybe paper. I can't tell you why it works, but it did.
