biffco Posted March 26, 2017 Report Share Posted March 26, 2017 Following the last trail I did, I now unfortunately have a crack between the sump plug hole and the case edge. I assume the only way to fix this will be to strip the engine and get it welded ?! With this in mind what parts at a bare minimum will I require ( seals, gaskets, bearing etc...) I don't know anything about the history of the engine, the power seems ok ( though I have never rode another MAR to compare it to), but whilst it's apart what else would you suggest I consider doing to it ? On the same trial that I cracked it, it started slipping out of first gear and going to neutral. I have re-ground a better point on to the detent pin which has improved it. Again whilst I have the thing in bits, is there anything else I should consider replacing to improve the gear selection ? These are photos of the cracked sump and of the piston and bore looking through the exhaust port. Quote Link to comment Share on other sites More sharing options...
totalshell Posted March 26, 2017 Report Share Posted March 26, 2017 if its no longer rideabl i d have that out and stripped down for a full rebuild or replace with another last i saw Adrian at TOR had taken in a bulk supply of MAR's and associated stuff 1 Quote Link to comment Share on other sites More sharing options...
