Kdtx240 Posted April 25, 2019 Report Share Posted April 25, 2019 (edited) Hello It's wonderful to join you all I have a tx 240 but the disc valve came loose and jammed, I would say it's a catastrophic engine failure as the flywheel slipped, crank gears slipped, disc valve broke in 2. Flywheel previously welded on and crank taper is in bad shape. Cylinder and piston are fine and bearings all ok Where would I start looking to get a rotax 240 engine to replace my old one or part to fix her. I bought a rotax 122 engine but it would require some fabrication to work- drive sprocket won't fit its too low for the chain. We're worried about the strength of the frame if we start cutting. What alternative engines are there for this job. Preferably 2t but if 4t is easier and fresher and has been done before. It's not for competing just a project but due to the age of her we want to do it right This bike is the same as a swm gori and Armstrong The sprockets are on the right if your sitting on the bike I am open to your ideas and any help would be much appreciated Many thanks Kdtx240 Edited April 25, 2019 by Kdtx240 Quote Link to comment Share on other sites More sharing options...
