i havnt realy done any miles in it as ive only just put it back together. but it seems to be at lower revs and not realy under load. I havnt had a chance to try it under load as its not road legal yet.

There is no rubber boot on mine, infact, theres not alot of anything.

As far as i was told , it was fine in YUM and had a rebuild a couple of k before i got my grubby mits on it
