jetting a 780 big bore srx

If anybody is running a 780 big bore kit on their srx, I could really use a starting point for the jetting using the stock carbs (not bored out). Thanks alot!

Thanks! I'll be riding this weekend! Mine is an '01. I raised the needles one clip to be safe, and 42.5 pilots. Is that what you did also?

jetting

i left the stock jets in it and did change the needles after I stuck one piston. What are you running for clutching? thanks

I have some 8BU's still in the package, and a WWW primary spring. Hopefully this weekend, I'll be finishing it up. I'll be busy porting somebody's rev ho 'till probably 3 in the morning so, won't be working on it tonight. Do you have any nice clutching setups for the 780?

clutching

as far as clutching I run the red maxximum perf primary spring and the 8BU-00 and a 48-42 helix with the heavy secondary spring. I have been trying to get the sled to work well drag racing but I still need some tuning.
