no power from motor mod

klx110man · Dec 31, 2010

i have a 08 klx 110 that i use to have a trail bike 143cc big bore with race head and a 26mm carb and 4 gear drum pro-circuit pipe and bbr u-flow on the bike. and then the bike blow up so i had it rebuild to...........

it's now a yz160cc with the race head and all the other parts are the same.........but now when the bike is warm and you try to take off it wants to kill so you have to run with it to get going and then when you are going it has no power at all.

so i was wondering if any one might know what i should try to fix the problem.

the carb is a oko with 125 main jet needle is all the way to the top.

You need more fuel due to two things. 1. You live in mn as I do as well and its winter so the air is denser there for your getting more air now then you do in the summer. With more air you need more fuel. 2. You are running a bigger motor now so you need more fuel due to it burning more fuel.

check out your spark plug it should be a tan color...if it's white refer above....if it's black you might be too rich....you need to check compression too...

I would think many vendors on Planet Minis would have them like Trail Bikes!!

so is a 26mm carb big enough or do i need to get a bigger one or can i just get a bigger jet.

26 is plenty. Main's likely too big.

If the plug is white and dry then you need a bigger main jet for sure!!

I would go bigger pilot also if it wants to die as soon as he hits the throttle because the pilot controls idle and low end. If the pilot was the rite size it would take off good then die down but its doing it all around so i would bump the pilot up one too. Probably #38 or #40
