what am i looking at?

[QuadRacer18]

im setting up my engine for MX it will have/ already does have the following:

-Curtis sparks 440 big bore kit 11:1 compression
-Stage 2 port and Polish
-Crf 450 timing chain
-WB r-4 slip-on
-K&N airfilter-open airbox

Do you guys seeing this quad having problems keeping up with the 450's? I already have suspension done to the bike if you were wondering.

I'd say it'll depend on what the 450"s have had done to them.

And of course rider skill.

Its really the rider more than it is the ride.
