Re: WRIST PIN SIZE ?

sorry about the all caps

Re: WRIST PIN SIZE ?

Most A3's had a 10mm Wrist pin but I belive some of the later A3N'S Had a 12mm.

Whats the difference between a A3 and A3n ?

Re: WRIST PIN SIZE ?

The A3 has the 10mm and the A3N usually has the 12mm wrist pin.

I belive thats the only difference. Search the performance forum and you should find tons of info.

That would also require a new piston and connecting rod, wouldn't it?

Re: WRIST PIN SIZE ?

Yea obviously the piston would be different, I dont know if the conrod changed or if it had a different bushing at the end. I guess brock would know.

alright, some A3-N's do use the 10mm wrist pin and i found that out wheni opened up my cyclinder and my 45mm parma kit would fit. Right now i sanding down the bushing. I need like 1 more millimeter. You could buy puch bushing and it should fit..Yes i've been sanding for a couple of days!

I've got a 12mm pin on the way and a tomos a35 70cc complete speed form MARTIN RACING PERFORMANCE . I guess when it gets here I'll find out . If you guys know any tricks please let me know .
