cylinder bore size

[tjm52]

What is the largest bore size for a stock cylinder.

I thought 66mm was the most that you can bore it to

but someone else told you can bore it up to 68mm

You would have to resleeve it to go 68mm. 66mm, 100 over is the max.

Correction...

66.50 mm is the largest, which is .100 over...the max for a stock set.

I'm telling you...after .080 those water jacket walls are pretty thin..

 

64.00 mm is stock, figure each .010 over is .25 mm.

 

Each .010 over (or .25mm) gives you 2-3cc's, depending on the rounding factor..
