I have an 89 that's in the process of getting rebuilt right now. It has full fmfs, v forces, and just got a cool head with 20cc domes.
I'm about 300 feet above sea level
temp ranges from freezing to 90s
Don't know my compression yet
I'd like to use 93 octane fuel, would I need something stronger for the new domes?
What should i jet my carb to?
I'd like to get a timing plate while everything is apart
would that affect my jets?
Would I set it to +4 and what fuel would I use?
possibly drilling the box for a little more power?
I don't have the money to my jugs get ported right now but is there anything else you guys recommend while the motor is apart? Maybe getting the crank welded? can an average shop do that? Is it expensive?
I also have boysen reeds I can use, which is better?
I'd like to have a fast motor but something reliable, am I going in the right direction? I'm looking to shut down a yfz450 and the rest of those 4 stroke punks
Let me know what you guys think. Thanks.
