Depending where you live and weather. I would try a 180-185. Should get you really close with the lid off.

what jets are in the carb now?? top end sputter soundss like the main is off.

I run a 195 main with the stock pilot...

I have the same piston and cam but with a Sparks exhaust and Dyno Jet Kit. Before I installed the jet kit....I was running a 185 main w/ stock pilot and needle. Ran good but I'd recommend the Dyno jet kit if you dont plan on getting an FCR. I got great gains in throttle response and some bottom end gains.

What jets do ya have now is a good question though?

I have HRC cam and needle and Sparks exhaust and I am running 190 main, HRC needle middle (3rd) clip, stock pilot on 108 race gas.

With that piston it requires a smaller jet, I have the full bb pro system, je 13:1 hrc cam, K&N filter with the hrc lid, I run the hrc needle, a 188 main, an the air/fuel mixture between 2 an 2 1/2 turns out... Hope this helps...

Also make sure you got your timing back correct...
