The bike is from 2002.. I'm not using a bigbore-kit like athena or something, I'm going to bore the stock cylinder with help from a local shop who's doing that kind of engine work.. I've got the newer crank from rm125 04-10 couse wiseco does'nt produce 58mm pistons for the 01-03 RM..

When I get the piston its time to modify the crank to make clearence for the larger 58mm piston.. Need to check out the clearence for the exhaust valve too, does anyone know if this is a problem when you big bore the rm:s? Have read all info on Eric Gorr's webpage but I didn't find any info about that...

We would also do some cylinder porting for mid-top.. A V-force3 reed valve will help the bottom too..

Sweeeeettttt. 8) I think when you order those pistons you should order 2-one for the bike and one to sit on the bench to look at :o 8)

I'd rather a full bottle in front of me than a full frontal lobotomy.

   You must  ride  really  rocky  tracks,  the  HGS  pipe  is  alot  thicker  than  a  pc  or fmf.  I   had  a  HGS   and   a  PC  pipe  on my  01 RM125,  the  HGS  had  a  much  bigger  increase  in  torque  and  hp.  Sharp  lookin  Rm ,  I,m  sure  it rips.

The bike is from 2002..

Are you sure? '02 had a tapered swingarm. Your swingarm looks like an '01.  Great bikes.  It's gonna rip!  8)
