Weisco Big Bore Kit for your DOHC CB750 or CB900.
67.5mm pistons (5.5mm oversize), 10.25-to-1, Weisco 4218M06750 (x4), with rings and pins.
Using the stock 62mm stroke will get you about 890cc. Using a 68.78mm stroke will get you 985cc.
These pistons are LIKE new, minimal use, with a very small amount of carbon on the tops. Direct from Weisco, they're $152.32 each ($609.28 a set), plus shipping/taxes/etc. You will obviously need your cylinders bored out to match, but as luck would have it... I have CB750K cylinders that have already had that done. What's a bored set of cylinders worth? I'm not sure....
I know that I am never going to use these on my ratty CB750K and someone here can put them to better use.
Asking $500 for the whole set including the cylinders, plus shipping. I will consider splitting up the set. Located in Southwest Ohio, Northwest of Cincinnati. You're welcome to pickup to save postage cost, or if you want to have a closer look for yourself, email me and we'll set something up.
