| RD RACING - to answer your question its an xr50 engine with a kitaco 88cc big bore, kiehin PB16 with a #38 pilot and a #62 main, stock needle... and most importantly a KP31 turbo out of a diesel smart car.
Power Man - I need it turbo rich! that means whenever its in boost it needs to be more rich than what you would tune it for normally. Normally it would be at aboue 12.5:1 a/f for best power at WOT but with the turbo it needs to be at like 11:1 a/f as to not blow up in my face.... It runs really good down low so i won't be changing the pilot or air fuel screw i don't think. I just need it to be slightly richer in the midrange and then go to full out rich at wot
Oh another quick question... what main jet would be run on a 125 or 140cc engine?
Thanks for your help so far, that diagram is a good baseline |
