Guys,
I'd like to build an XS650 engine that has a bunch of missing parts but I don't want to use a doner engine that could be rebuilt itself. I'm hoping to get some help here and let you know what parts I need in hopes that you may have it on a shelf somewhere and don't have to take it from a potential rebuild engine. If you catch my drift I think the effort will be worth while. I appreciate your help in advance. I'll be putting a list together soon. Gracer
 
I'm making good progress on the engine build. I now have the bottom end all buttoned up. Gears are shifting, able to find neutral, kick start installed and works. Question: on the oil filter (in the side cover) how much should I tighten the plug that holds the spring and ball? I'm thinking make it flush with the tube it threads into?
 
I got a bunch done on my engine build. I soda blasted the head and rocker box but it still shows some corrosion. I finished porting the head, lapped the valves, installed new valve seals, rocker box seals and rocker arms. I bought a complete head to do this and put those parts in the head I had with matching rocker box. Everything went together nicely! Cylinders are being bored this week.
 
Ebay has lots of engine parts. You can finish the rebuild of the second engine that way. Maybe build it a bit different than the one you have. I like the 750 kitted engine I my 75.

I'll consider that for sure. I see 700cc and 750cc discussion, is it just preference or is there a big difference in power/price?
 
700 is about the limit on stock cylinder liners. To go 750 you'll need liners with a bigger OD.
