Fitted new pulley & belt, still seems high revs to get going, tried it in 5th gear with 50 degree pitch , started to lift at about 7000rpm but took up to 10,000 rpm to get moving, once going could ease back to 9000rpm but engine started to overheat, someone mentioned a 35 degree pitch in 6th gear , would reducing the pitch allow the revs to drop ? Also steering seems to be non existent ( or is that normal )
