i hav a scorpa 1996 250, its a very clean bike with no faults as far as i no (ive only just got it) i used to ride motocross bikes and i had a to change my top end a lot, is this the case with trials bikes and if so how often, and how often should i change my gear oil and whats the best oil to run it on? and wats mix should i run it on? last question when the crosser used to get hot i had to let it cool right down then it was good to run again so the top end didunt go. do i have to keep an eye on the temp of the scorpa
any help would be great, thanxs matt
