need help on jetting start point.
Have a 44.1 mini stroked 50mm PG bore, PG Long, and 28 mm OKO Carb. (Builds in signature)I'm looking for a start point with my jetting. I was way over jetted trying to cool my high compression now, I have no clue what sizes to order. I have pilots 50-60 and mains 145-158. Thanks

55 pilot 140 main air fuel screw 2 turns out needle clip middle. try it with the 145 you got and see if thats to rich first.
Nothing like getting stroked!

Re: need help on jetting start point.
I'm running 145 now its to rich from 1/2 throttle to full throttle ther really isn't any speed gain and my rpms are maxing out 8k. but if I'm cruzing in 1/4 to 1/2 throttle range temps get up in the 360'sbakaracer wrote:55 pilot 140 main air fuel screw 2 turns out needle clip middle. try it with the 145 you got and see if thats to rich first.

Re: need help on jetting start point.
check for a air leak and make sure the compression is 125. use the kick lever and not the electric start to check that. also make sure your not using a long hose and a adapter for the compression tester. it adds volume to the head so compression readings will be lower

How many psi do you think the hose and adaptor adds?

Re: need help on jetting start point.
the is no information about the crank case port or untouch porting...
that is the reason why you went blow up 3 cylinders...
crankcase need to clean out real good.
any metal shaving lay on the bottom crank case... from seize bore. any metal shaving damage crank, crank bearings...
