Dude, 18cc to a 21cc is a pretty big jump. What exactly are you looking for?

The lower your CCs the higher your compression on a given motor. The higher your compression the higher octane fuel you must run on any motor to prevent detonation. Your altitude and your porting will effect your compression. So everything kinda ties together. You really should talk to the guy you want doing the porting to determine the compression as the durations play a big part in the calculations.

What kind of fuel do you want to run? 93 octane, some type of race fuel, to run pump 93 octane at 450ft you should stay around 21's.

do you know a cheap place to get a good port job and like i said what type of port work should i get and yah i plan on runing 93 with octane boost so i would run 103

also wich size domes should i run

 

You should talk to the guy who is going to port your motor, a good motor builder will set you up for your riding style.

IMO don't just do a cheap port job. The difference between a cheap port job and a quality job is a couple hundred bucks and worth a ton more! There are several good builders on here that are reasonably priced and you wont regret for sure. Herr Jugs, FAST Racing, Passion, and the list goes on. Check around, find someone your comfortable with and you will be glad you didn't short yourself. Don't take my word for it, ask the other guys here, porting is the heart of it.

Any good motor builder will answer all your questions and will port and build your bike accordingly,they will tell you what pipe carbs and timing and compression and everthing esle involved. DON'T go cheap on your port job it is EVERYTHING when it comes to a 2 stroke.

You're going to want a port job that emphasizes on low to mid power for the riding style you talked about. If a builder tries to sell you on drag pipes and a dune port ect. just walk away.
