Re: 1981 Honda CB650 Custom Main Crank Bearings

Oh man, what a journey on my CB650 so far! I can confirm that the shells in the 500 and 550 are the same as the 650. They work and fit perfectly in the 650 crank case with the exact tolerances specified (Haynes Manual). Enjoy all!

Re: 1981 Honda CB650 Custom Piston Kit

I sent them one of my pistons' a few years to give them something to copy, so they can hook you up with some Pistons for around $650 American. I had them make me a set for a 61 mm bore, but they may be able to c...

Re: 1981 Honda CB650C Clutch Rattle

HI guys! Thank you so much for your replies, sorry that I dissapeared. Work became hectic. I opened up the clutch and found everything to be in order. Turns out it was the carbs, the main jets (4 of them), were odd: 3 were the same and original, 1 was odd. So the cylinders fired differently with ev...

1981 Honda CB650 Custom Piston Kit

Hi guys and girls!

I am looking for a new piston & barrel kit for my 1981 Honda CB650 Custom. The barrel is actually okay, a piston kit is more important. I am from South Africa, does anyone know where I can order a piston kit? I tried Wiseco, no luck. Thanks!
