i need help

i have a 1998 wr400f and i am looking for a way to get better bottom end out of my bike if anybody knows i would like the help thanks

Cory,

I have seen bolt-on flywheel weights advertised for four-stroke bikes that apparently boost bottom end power (probably at the expense of top end).

Not sure how well they work (maybe brilliantly, I don't know).

They look very easy to fit.

Worth considering.

a flywheel weight will only make the bike take longer to rev up and hit smoother than without it not add bottem end.

For bottom end get a pipe, but your best bet would be porting

Have you done any thing to the bike yet, Exhaust, jetting, Gearing, Air box mods? If the bike is all stock then there is a bunch of stuff you can do to help the bottom end.

Try running WR timing...or a high compression piston...or a big bore kit...

Your are dead right ... I wasn't thinking !!! (Rushed the response). :thumbsup:

The increased flywheel inertia should have the effect of making the bike more "tractable" and less inclined to stall at low revs.

If you do a lot of low speed "chugging" in tight-going it would (in theory) make the bike a lot easier for you to ride in these situations I guess.

Never tried one or seen one on a bike myself but they sound like they'd work to a certain extent.

Depends on the weight of the unit I suppose.
