Jumpy 280

Featured Replies

just bought a 2008 280 and its too harsh whats the best way to tame it a bit to make it softer like the 250

Flywheel weight and a slow action throttle works well.......

any idea of cost for the flywheel wieght and does it make much difference???

Hi rodmac,

I have used the Hebo flywheel weight on my last 2 300 Ragas, it is 750 gms and makes the motor more user friendly down at low revs, bril up rocky creeks (ok then, burns). Don't know the price in the UK. You need to drill and tap 2 x M8 x 1.25 threads in the flywheel when fitting. It definately helps smooth out the low end. Also, you can fit a slow, black tube throttle and even fit 1 or 2 x 0.8mm base gaskets - don't like doing that though as it raises the exhaust port, but it does work.

Biggest problem for me, is the gearing on the 08 bikes, even with a 10/42 the overall ratios are too high, it is like riding the 07 bike with 11/42. I am fitting a 9T on my 08 Raga (when it arrives), though as a few lads point out, a 9T sprocket is not too friendly with chain wear with a 520 chain, could go the other way and use a combination of 10/46 which is mechanically more suitable.

Bye, PeterB.

I dont have any experience of the flywheel weight on a 280 but i fitted one on my 250 and it makes a nice amount of difference, dont get me wrong it wasnt a ureka moment but it took enough of the edge off and allowed me to find more grip in the slippery stuff (more controllable). I bought my flywheel from trialendurodirect.com and i believe it was
