40cc Cag Upgrades

[midnightmidget]

Hi guys i have a a/c cag. Thought it was a 49cc but just found out its a 40cc.

Was looking at ozminimotos RD 3D Head kit (Ozminimoto - Mini Pocket Bikes - Product Detail) but he said i require a 12mm piston pin. Now im guessing i will have a 10mm being a ebay 40cc cag ?

Is there an easy way to replace the whole setup so i can get ozminimotos RD 3D head kit?

OR,,,, i was looking at these HK Moto cheap ebay kits. Its a "MINI MOTO ADA TOP BIG BORE 4 PORT CYLINDER CIRCLE CRANK" (MINI MOTO ADA TOP BIG BORE 4 PORT CYLINDER CIRCLE CRANK - eBay Parts Accessories, Pocket Bikes, Scooters, Sporting Goods. (end time 14-Sep-08 05:37:17 AEST))

Whats everyones opinion on this? Get this, or can i somehow get a full circle crank/head kit to suit my 40cc with a 10mm pin? (Or do something else to be able to use ozminimotos kit!)

I have a jetpro pipe and 14mm del rep carb with reeds on the way to be fitted.

do what bj said, then if it wont fit just buy a full circle crank that will fit, then buy the top end. or buy a kit with the crank included.
cheers

You'll get most of the things with the kit anyway
such as a new piston pin and piston so it won't matter.
The bottom one has the full circle crank so your set!

i just installed a ada style big bore kit and full circle crank from hkmotos and 15mm del rep from them also and the difference is unbelievable and its still only running it in.
i also hav carbon fiber reeds and fatboy pipe which is all made a difference. allthough the fatboy pipe is still to impress me. thinkin bout findong a jetpro and see the difference.
the kit seems to be of good quality and it only took 8 days to get here. so pretty good coming from china.
