[big pit 007]

ok so i have fattys no lid with k&n. i am at 1300 ft at home and run 300 mains. mostly ride at oregon coast and was a lil fat at the bottom but not too bad. so my cdi went out and i got an after market one by AMR racing stage 2. tried to get a timing curve but no luck. i have added a timing plate an cool head with 19cc domes. 160lbs compression an a dead cold engine.can i still run +4 degrees timing? and how much should i jump jetting? oh and am going to run 50/50 race fuel. any in put would be greatly appreaceted!!!

well, if you are gonna run 50/50 in those cond. then +4 will be fine......if the amr hasn't advanced it too much already...all i can tell ya is to check the jetting when you get where you are ridding and adjust then.....probably 310
