4rt Flywheel Weight

Featured Replies

Has anyone figured out how to add flywheel effect to a 4RT?

yo, motovita.......I too have gone down that road, but with no availe......what I settled on was the 260 kit, which has a geat TORQUE cam as part of the package

the bike needs a flywheel!

I have the answer!

I had extra flywheel weight fitted to my 4RT by a very clever chap called Jon Bliss. It absolutely transformed the bike, but don't tell anyone.

Jon makes the "Cotswold" twin shock trials irons too. Ring him on 01242 239055 (Cheltenham) and he will talk you through the mod.

Jordan 80, thanks for posting. Any chance you can get me an e mail address for Jon Bliss? That would save me from having to get up in the middle of the night to call him, as well as an expensive phone call from the states.

Jordan80,

How did the Bliss add on transform your 4rt? did it have a good effect on grip in the slop? and how much does it cost fitted?

Okay, can anyone on that side of the pond come up with an email address for Jon Bliss/Cotswold? I'd sure like to contact him.

hey,

Jon does not have email just call him he is a very helpfull guy he does this for the sherco 4 stroke aswel

regards bob

Sorry for the delay, My son hogs the PC. With the addition of the extra flywheel it takes the bikes' engine charateristics back to the late 70's/ early 80's. Much more grip in the muddy stuff due to the motor taking longer to slow down on a closed throttle. You can also pull a higher gear with no fear of it stalling. I'll contact Jon and tell him to get a bloody computer!

Thanks Jordan80.

It's a good thing that the Montesa will last you a long time. It's obvious you don't like acquireing Trials bikes!
