pull the starter 2-3 times with choke, if it doesent start, put it half choke and then try again. If it still fails to start, then turn the choke completely off and give it another 2-3 pulls.

dont put the gas cap on too tight, you might be creating a vaccum, which keeps the gas from flowing into the carb, ultimately not getting any gas to the engine.

make sure you use some 28-30:1 break in mix, if you have some starter fluid put some in the plug hole and try again.

:thumbsup::thumbsup:

Now, so you dont wreck it like the previous owner... make sure you give her atleast 4 tanks of break in mix like I said above 28-30 to 1. 1 tank let it idle with the occasional rev up, 2nd and 3rd tank ride in different RPM ranges in the lows and mids, 4th tank put it at wide open throttle for a bit, but dont stress the motor too much.

After that 40-50:1 fuel/oil mix, pretty much to your discretion..

Dont forget to wear a helmet....

how do i sort out the idling? then an i worked out the clutch drum (bell) is rubing ever so slightly and terning the clutch a lil but that will where dawn haha i hope

I sand my shoes on the high sides, when there new only 1/3 of the shoes touches the drum. That's on the China bikes, but any brakes or clutches need time to seat. I just put a 3 shoe china clutch w/ Banshee springs, had to run it, take the bell off, sand the places that were polished a few times till most of it was hitting the bell. On the idle there should be a spring held screw on the side of the carb.
