reliable performance mods

[supersick300ex]

I did some searching, but couldnt quite find what i was looking for, I am just starting to race in harescrambles and XC races, i have done a few MX races, and I would like to know a few other mods I could do to achieve a little more power, In my 2005 R right now I have a full Yoshi TRC exhaust, stage 2 dyno jet, K&N flow kit with K&N top, and dynatech cdi I run in very dusty and watery conditions I also have diffrent gearing For diffrent races and Diffrent sizes of tires, what else could I do rather then cams and pistons, I know those will really wake it up but my father doesnt want me tearing up the motor just yet, since its a year old

[honda300EXtreme]

it sounds like youve done every mod without digging into the engine,,,

i would recomend working on suspension now... maybe a revalve/ respringing, and maybe a new linkage set-up..

[honda300EXtreme]

or you could get a better carb...

What about the boyesen accel. pump cover mod, Iam working on suspension mods right now what would you suggest I want elkas but there pretty pricey, whats a good complete front end kit

[honda300EXtreme]

in my Opinion the boyesen accel. pump cover is a complete waste of money...


to be hones i would have your front shocks resprung and revalved and they will be just as good as aftermarket...

but if you going to widen the front end and arent looking to spend a ton i woud go with burgard a-arms and TCS fronts...

What about diffrent cooling mods to keep my power throughout the whole moto

[supersick300ex]

so, if i was to get diffrent pistons, what size should I go with out doing alot of major things, all I want is lil more power So i dont want to bore it or port it, and I dont want troubles trying to start it

[honda300EXtreme]

well considering the 450 has a radiator and a fan that helps alot...

as far as keeping cool make sure your jetting is right and alot of people use engine-ice antifreeze with a additive called water wetter and it really does help lower engine temps...

[supersick300ex]

I forgot to mention I use engine ice, My jetting seems to be smooth I have a pro circuit Air mixture screw So I think shes in tune

[honda300EXtreme]

yea sounds like you got things covered, i would get some good suspension and you should be set ;)

Get a drop in cam, such as the hotcams.

They are SUPER simple to install and you don't have to "dig" into the engine, just take your gas tank off and valve cover (3 bolts) and you'll be looking right at the cam.

Makes a world of difference.

your best bet would be a drop in cam as stated above,, a all around hot cam will make a world of diference, and considering you bike is relativley new theres no need to change the piston yet,

and a cam is a simple job

get rid of that k&N and put in a uni if u ride in very dusty cond. you can kiss your motor good bye.

[450rJam]

diddo on the cam, cheap and easy mod.
one of the best power boosts you can do.

[GIXXER1KR]

Do a cam and the K&N is fine just run an outerware.I have been running them for years on everything in my garage.
