Hello all, after close to 50 years of road racing, I've bought a 1991 Cota 310. I didn't want to spend a lot of money for my first attempt at trials so I'm happy to make and modify parts but I'm a bit lost without a workshop manual. I've searched the internet but can't find one for sale so I was hoping someone on here may be able to help.The swinging arm spindle was seized solid in the bushings so I've fitted new needle rollers amd made new bushings I've fitted new taper rollers in the steering head so the chassis is now OK but without info I'm struggling to get to grips with the engine. I have a puller for the flywheel but can't get it to shift, I've done the usual ie. tightened the puller as tight as I can (very tight) hammered the end of the puller but to no avail, has anyone any ideas? I've pulled the primary cover off today and found a clutch that looks nothing like any clutch I've seen before. I would be very grateful if somone would help me out with any information.
