Wrist pin adapters for BBK?

caferacer · 10-20-2004

I need two wrist pin adapters so I can get my BBK installed.
Does anyone know where I can find these without having to purchase another kit?
I have asked the only two vendors I know that sells the kit and one stated he only has enough for his kits and the other for some reason won't say one way or the other.
It's not that I haven't spent any coin with the both of them either because I have.
Doesn't seem like this would be a very difficult item for someone that sells the kits to come by.
Who knows....I'm open for sugesstions if anyone has any.
Thanks

I did not know that there is a difference since I have not messed with many big bores. I will see what I can come up with in the shop and try to get you a lead. It is amazing how many 43cc and 49cc gas scooter parts are inside the 40 and 48cc Cags.

I doubt you will find the adapters in any other motor, scooter or not. The adapters are custom made pieces made specifically for using a 49cc piston on a 40cc motor. The only way around not using the adapters is to use the 49cc connecting rod, wristpin, and roller bearing (along with the crank if your not capable of removing the connectiong rod).

I messed one up and a friend who has a metal lathe made me one.Took all of 10 minutes. gGo to any machine shop & they can make them.

Hi!
I am also looking for wrist pin adapters for BBK.
Anyone can help me?

Thanks

If I cannot buy them, can I just make two aluminium cylinders to go over the pin?
Anyone can advice me, thanks?

It's for the first time I do not get any answer to my questions. Must be ****ing you all off guys, sorry!

I will just try one more time with a picture and would be very grateful if I could get some help.

The wrist pins have the same diameter on my 39cc and my big bore (10mm).
The bearing itself fits well on the wrist pin so no problem there. My only concern is that the bearing can move horizontally on the wrist pin. The space in too big. Is this a real issue?

Thanks
