Built motor assist trike,downright dangerous when pushed.. Pulled it apart built recumbent,to hard to pedal to engage clutch(getting old)..Fitted50cc high comp 2stroke all finished and looked O.K even got it up and running was really rapt...THEN,pulled the starter ,it broke,fixed pulled rope broke,fixed after replace cord upsize handle broke..,Total 6 cord breaks,new internal bit fitted return spring disengages 4 times,another handle....s**t on this ,now fitting starter motor,nearly finished am on MK111, not the easiest job I have tackled on bikes,Wife says it is trying to tell me something do not finish the thing and throw it to landfill..Kept me busy building this over winter do not want it to beat me... NOW,the hard luck story ,new engine got it running up to temp torqued the head down ,piston comes up hits plug of course it not only has no spark the plug is trying to stop the piston going back down hence a cart load of use to cord pull creating probs.. Fitted thick fibre washer to plug maybe2-3threads worth engine running up to temp am a happy camper oil coming from head joint torque down head/cylinder bolts,crap appearing at cylinder to crankcase..Only 4 bolts so strip it down,Now not happyNEW ENGINE run fo total 7minutes...No gasket at crankcase ,a really heavy consistency glue ,not silicone ,impregnated with like asbestos 2 times pulled head down squeezed out underside unable to see,into crankcase etc; .. long story/short engine back together ,washer still on plug,maybe wrong plug,starter almost there But now I am thinking of throwing it down to the Tip...Not really a Recumbent more a very.,very low trike ,will try to get some photos ....
Bikes easy they are generally on 27inch wheels,lowriders/recumbents 20inch to do any work on the damn thing must be up on bench..Will keep you posted Stay Safe
