i e-mailed c&d racing about ordering parts and he said he suggests a stg2 cam. i had planned on stg one because im going to be boring it to a 416 and 11:1 compression. wich would you choose? i will be racing harescrambles and a few motocross races.also with the 11:1 i had a guy tell me i could still run pump 93 octane but would it be better if i did a 50/50 mix?thanks for all the help

teh cam is up to you and where you think you will need teh power. i had a low end cam adn switched to a stage 2 cam and would never go back, but thats jsut me. i would use the stage 2. as fro teh gas, pump will be fine but it you wanted to for a little extra safety you could run a 50/50 mix.

50/50 mix ok?

i have a 400 with stg 2 hot cam and 11;1 comp piston with timing advance key from curtis spark and full exhaust with ported head and have ran pump gas in it from day one bout 4 months ago and never had a problem

[honda300EXtreme]

different people do different things its your call i run higher octane to prevent detonation, and to answer your question anything higher than regular will help

For best performance, use the least octane as possible. For 11:1 streight premium pump is completely safe.

alright sounds good then. i ended up going thorugh C&D racing, very good prices. i ended up with JE416 piston 10.8:1 , stg 2 hot cam

Very similar to what I went with except I had him do some headwork and mine is 426cc now. I'm fine on premium fuel. I was a little worried once I got it reassembled if I would need a mix. Fortunately to date, one ride, I don't.

However my elevation is most likely higher than yours and that may make a difference. FYI, I've ridden from 3300 to 4000 foot elevation. I know my pickup knocks like no tomorrow once I get below 2,000 feet if I don't add just a little bit of premium. Near sea level she's much worse if I don't remedy the situation.
