More Power

[timmersam]

I was looking around for a while and seen the endless amounts of go fast upgrades for the 250r, but alot of them have to do with bumping the compression to the point where race gas is needed. I was wondering what is the best thing/will make the most power for my qaud and still be able to run on pump gas?
Thanks alot

you want to take off the airbox lid and throw on a filter for sure (you'll get varied opinions between K&N and UNI- i prefer K&N), a rad valve, a larger carb (36 or 38- depending on what your eventual future plans are)...

you can up the compression a bit before you have to use race gas... having your jetting spot on is one of the main things that will make a difference.

reed spacer, lighter flywheel, different cdi box, octane booster, pipe, airbox lid off, air filter, carb, bigger top end

its only what i have seen and heard,,,,,,,,,,DONT EVER RUN OCTANE BOOSTER,
stay away from K&N filters if you dont want anything in your engine
the cdi box is an affordable upgrade dynatek makes 1 for less than 100
reed spacers dont really give you any real gains ,what you will gain in lower you will lose in upper

aftermarket reed cages ie -v-force,duncan pyramid,or the boyeson rad valve

I couldn't afford to go ride and eat, so I lost 40 LBS, What a difference! That's cheap power right there.

power valve cylinder and the right jeting will make a difference

I can run a power valve and still run it on pump gas???

no one mentioned porting???

Of course you can. You can run any cylinder on pump gas as long as you get the proper parts to suit the engine.

All a "power valve" cylinder does is alter the exhaust port timing to give you a smoother, more user friendly powerband while still letting it have good top end power. The main thing (but there are many other factors like porting/pipe) that affects the fuel type needed is compression ratio.
