So I have a 86 trx bored to 67.50 Paul Turner 89 race pipe decked cylinder cool head 20cc dome ported rad valve no airbox lid runs on 50/50 110 and 90 ethonal free. I race xc and have a bored out pj 38 and don't care for it. Just bought a pj34 bored to a 36.5mm what's a good safe jetting starting point on everything?
Ok I'm in the rich side or "safe side" now with my pj38 you think it would still be safe to swap over my current jetting to the pj34? Also am I wasting my time doing this? Will it be a good woods runner and be snappy?
Well the pj34 came un today and I had the quick idea to swap my 55 pilot to the 48 that came in the 34. And it made the motor feel like as soon as I shifted and hit the throttle it was there sooner. So on my pj38 I have a 48 pilot 172 main and it seems to run nice. These numbers seem good for a piped 67.50mm reeds open air box decked cylinder and so on?
