Prolly won't be to far off with the 107/48 if it's Idling smooth gotta be close. I'm running a 110/42 in my 21 oko on 65cc polini af05. Bit mines not fully dialed in yet either. When I did my heat cycles I did about 4 to 150-200 degrees and about 4 to 300 degrees and 4-5 to 380-400. Took her easy for about 60 miles and then started crackin it open here an there. Just watch your temps once you start actually ridding it. Prolly over kill but better safe then sorry. Running temps can be anything up to 350-400 just gotta watch the great spike after running wot. Took the polini to 430 degrees a couple times no problems but I'm running 100 octane fuel.

yes your doing fine .Id try the 42 and 102 remember its only 65cc and you now have a ported block.the bigger those intake windows in the block the smaller jets you need .Air speed from the carb to the jug changes jetting

paulpauly7 will do today if the weather get nice out ...going to do the main jet first then the slow jet then clip position ...... or some other order???

just got done reading it ... as well as listing to it... (Natural Reader text to speech software ) bu what i have read it running rich all the way a round ... dose not say a thing about a temp Gage on tuning the carb ... the temp at idle is about 160 and on a ride at 3/4 it get to about 256 so its running cold to munch gas running in the mix ???? i think???

Ok, just remember you are still breaking it in. just take it easy with it and read the plug . keep an eye on the temps so it doesn't get over 400 and let it seat the rings. Rich is better than lean, you know that. You will get to tune it as you go. The main thing about the temps is that you get familiar with the engine and where it runs best at, and how performance acts as you change the settings; i.e. plugs; br6hs to a br8hs, or jets, or needle clip setting, or fuel to oil ratio. Do you have a tachometer? Learn, have fun and be careful during break-in. Give it the time it needs to "run-in". Keep us posted and enjoy the nice weather you have waited so long for!

I have a total of 33 grams in my variator I think. I get her spinnin in the mid 9k range. I think the pipe is hurting you more than helping you.
