i bought an engine casing from a well known auction site last year which had been converted to use a motorcycle style barrel which i was told was rotax. after much searching ive not been able to find the cylinder that fits. i suspect it was an old air cooled version, and i want liquid cooled, any way ive now got the barrel i want to use, a rotax 580 twin, im only using one cylinder hence the title lambretta 290, 76mm piston and 64mm stroke. cylinder i bought is nos jetski version, ive got a head on the way from the states(snowmobile version) and piston to order yet, this conversion has already been done before if you look under rotax 300, built by ryan mason, im going to try and keep it as simple as poss, will stick a few photos up, but its not going to be a quick project by any means, will keep pics coming as i go along.
