240cc kits?

Recommended Posts

I have had interest in 240cc kits for a while. Basically around 12-1 with flat-top. I am thinking of using non shrunk rod on stroker crank so keep piston light, short and strong. Premium forging with real rings and rings are commonly available. I can take this down to 10-1 compression so would be ultimate woods motor as bigger CC's equals more torque. Anybody else need one? Not for profit as have to make minimum 4 sets. I need 2 so if anybody interested give me a yell. Also sleeve will be thick enough for up to 1mm overbore as I don't build one time only cylinders sleeves.

Do something nice to the house. DO NOT buy new kitchen appliances and think this counts (unless she specifically asked for them). Just a suggestion.....

What do you have planned for kick starter parts (gears and ratchet) with the added stress of 240cc's...........? :thinking:

I always hear the same thing. Funny in that I have owned one since the first XR185 came out. I grew up riding old BSA 441, TT500, hot XR500's old school backfiring 2-strokes. I have never tore one out. I do a proper starting procedure and never just wack at kickstart.  Now I have had friends ride my bike and tear it up in one ride. 

 

If at 10-11 compression I see no problem. correct spot, slow and steady and always fire for me. I do have compression release on handlebar like newer xr400's though Use it when I lock up rear in trails and bumbstarts easy while still moving.

If I make these with standard pin location it would be 216cc with a stock crank and 11-1. With stroker crank 240cc at 12.1. Of course I can knock compression down if needed.

Is the stroker crank you made for me going to work with this kit? Not sure if the one I have has short rod or standard.

short rod and yes it will work. Need to bore cases for larger sleeve. I made sleeve thick enough that 70mm can bore in for 247 later.

 

The long rod set-up will ONLY work with long rod stroker crank and special piston with altered pin height.
