I dropped the 1600cc engine out of my speedster and took it to the machine shop on Friday to have the block and heads bored out to accept 94mm cylinders. After picking alot of people's brains I decided to go with 1914cc engine with a very mild cam. I don't need more top end -just want more low end grunt. I found the 1600cc more than adequate at 70-75 mph.
My question is about the tranny which I assume is stock. A 2006 Vintage build. Inside the bell housing it is written in paint 412. The machinist said he could swap gears and rebuild for about $400-$600 which sounds reasonable. The present 1st and 2nd gears are really low. I am seeking advice from the guys who have switched trannys.
Thanks in advance
