Best jetting for a 2 into 1 carb for woods.

[markyb31]

I picked up 94 last week and have done some work on it and have it running good on the top end. The previous owner did not know anything about the bike (the mods were done before he got it) except the guy raced it mx style. I just picked it up for trail riding, and because it was $500. The thing fucking flies! I was told that it was gps'ed at 92 mph, I have had it in the upper 70's and it wants more! My deal is the low end. It does not like to go slow to mediem speed (sounds a little rough). Is this just the nature of banshees or can I tune it down for trail riding. I am running race fuel at a 32:1 mix, I was told it has to run on 110 octane or better, why is this? Also it has a 15 tooth spocket in the front, and a 40 in the rear, is this what I want for trails? Thanks for the help.

What pipes, what carb, what tires, and what size tires? Do you know what jets are in the carb?

It has a Dyna Port 2 into 1 pipe, turf tammer 18 x9.5 in the rear, and the carb is a keihin pj series, not sure what size , I think it is a 28mm, no idea what jets are in it right now.(silencer has no name on it)

Thats not a great trail tire, its a good dirt tire though. Thats very small also. I would put like a 14/45 or 46 on a trail bike with that sized tire. A 28 mm carb is way too small. You need at least a 33mm carb on it. I would not use a pj either, gt a pwk for it, the pj's are very touchy. I thought they didn't make a 28mm pj? I would recommend like a 35mm pwk on it.

 

What kind of trails you riding?

I am guessing at the 28. I am measuring it from the inside. If they are measered from the outside it would be bigger, maybe a 33 then. I live in Wisconsin so the trails are tight, narrow up north, down south where I live they are more flat dirt trails, like old railroad beds and shit. If I get the 35 pwk, should it come jetted right or should I consider changing the jets?

Your gonna need to change jets.

 

Are the trails muddy, rutted, and rocky?

A little muddy, but mainly hard packed dirt, with some rocks, and hills. I like power and speed, but I want a good lower end so I can cruise at times and not have to keep on and off the throttle to hit the best power curve.
