1976 elsinore cr125 cylinder help

Any 76-78 CR125 cylinder will work. There is no real difference betwen the years. Fins are larger than the 74-75 models and the bottom skirt is a lot thicker than the 74-75. I have been told that a 1978 cylinder has better porting specs and makes more HP but I have no way to confirm that. If you can't find anything reasonably priced, let me know as some of these people selling this stuff on Ebay are completely batshit crazy.

I also have a lot of piston kits for those if you find a good cylinder. If you find one close to original bore, look for a stock Honda piston. They are cast and come in .25, .50, .75 and 1.00mm overbore sizes. After that you'll be looking at aftermarket pistons from Wiseco or Wossner. You can get up to a 2.0mm overbore with those. The Wossner pistons are works of art and cheaper by far than Wiseco. Google Wossner Online to purchase. If you have it bored locally, make sure they chamfer the ports and relieve the exhaust bridge. The exhaust bridge needs to be relieved a considerable amount as that is THE problem area on those top ends. Piston on the left is a Wossner. Right is a later model stock Honda.

I have a couple cylinders with fresh bores and pistons. One has a new sleeve fresh bore standard. The other is first or second over bore, I have a lot of parts and nice 76 to 78 parts. M

I also have a complete bike I will be selling also with fresh plastic and RC replica plastic tank. I have a restored metal tank that going up for sale.

You should buy both of them if you plan on racing. You'll need the spare, trust me.
