im in the process of rebuilding a 85 rm 125, so where can i find a rear spring for my weight? also if anyone has any performance tips that i should do i'm all ears. i have most of the bike built up and i'm now working on the supension and the engine. for the suspension i replaced all bushing and seals in the forks and added race tech cartridge emulator with race tech triple rate springs. the rear shock i'm just starting to gather parts and having a hard time finding a spring, any help or advice i appreciated

Assuming you want stiffer rear spring, I think by 84-85 the rm 125 was sharing the 250"s shock dimentions, you should look for an 84 or 85 rm 250 shock spring, they will be stiffer than the stock 125 spring. If you want to buy a new spring, Cannon Racecraft can make one to your specifications...

If Race Tech doesn't have a spring, google cannon race craft, they can make you one. I've been going the gold valve route on my stuff and having good results. RT shows to have all the service parts to rebuild your shock. Good luck!
