dougalthedog Posted March 16, 2009 Report Share Posted March 16, 2009 Hi Rebuilding a TY250 Mono, Can anyone post a complete idiots guide to re-installing the generator and setting up the timing. Motor has been stripped and rebuilt by local Yamaha specialist. I could take the generator to him, but would prefer to learn how to do it myself. Thanks in anticipation.

stork955 Posted March 20, 2009 Report Share Posted March 20, 2009 Ummm, ok - I havent seen one of these apart so I'll try and give you a generic guide. Normally I will mark the stator before removal and just line up the marks on reassembly but I have to assume you haven't done this. For basic fitting the stator will really fit only one way around - use the wiring loom as a guide to show the orientation. Fit the retaining screws/bolts/whatever. You may be able to "ballpark" it by lining up the existing bolt marks - do so if you can. Otherwise go midway in the slots. I think your bike is electronic so - refit the flywheel. Now you need a timing light. Get it started and check the marks for alignment on the flywheel and the case (at the top somewhere) at idle speed. If they line up -great. If not, stop it, remove the flywheel and move the plate a bit in the direction you need. Remember that to advance you go against direction of roataion i.e. anti-clockwise. Vice Versa to retard. Refit and repeat. Keep going till you get it and your done. Someone let me know if this bike is a points one and I'll give you the procedure for that. PS -sometimes (always actually) it helps to give a year model as there are differences sometimes that matter! HTH Cheers, Stork Quote Link to comment Share on other sites More sharing options...
dougalthedog Posted March 21, 2009 Author Report Share Posted March 21, 2009 Cheers for that. The backing plate was marked - ive lined it up and have a spark. So once rest of bike is back together I can fine tune the timing. Pretty simple once you know how. Another job I wont have to pay someone else to do in the future. Once again many thanks Quote Link to comment Share on other sites More sharing options...
