hahaha ok :no:

im putting a carby on that is way to big for the bike in the hope that i will get more drive, was more asking some of the knowledged people on here on what jets to use

 

[sean01]

try the 82 main and the smallest pilot you got..

tune pilot/mixture and needle first then go for main jet..

will it fit on my super charger? haha

new info, i only have a 35 pilot & a 100 main so i will see how it goes

 

[eichkay]

you'll know rather quick if the pilots to big.. but it wont really effect you top end, just makes it hard to keep it running down low.. I think 35/100 should be fine as a starting point

 

[Hillz]

i only want to go wide open anyway

Weight loss will also improve top end

i run a 90 main and stock pilot on my 90

differant jets i know but might help

& the i think i need a new oring when i put the CRF70 carb back on.... some strange things going on here

 

[timeeh]

what the **** happened to that? P.S Well done on getting it running, what jetting did you end up with?

 

[Hillz]

100 main & a 35 pilot....

i dont know what happened to the oring, must of been heat & petrol over time

 

[timeeh]

thinkin i might try and put the 30mm (mikuni copy)off the yx160 onto the mrs lifan 125, i reckon if you got that to work I might be in with a chance.....

 

[Hillz]

easy.... i had a 28mm on a YX150
