1397 big bore street build

[jumjum01]

I am in the early process of building my 2001 hayabusa from stock to 1397cc bigbore.
I plan to use stock cams since want more low/mid power. I plan to buy JE pistons with 12.5 :1 compression so I will be able to run pump gas.

Has any of you done bigbore with stock cams? I would like to see dyno sheet from similar build..

Can I use / reuse OEM cylinder bolts?

Can OEM headgasket be used?

A couple people have done this back in the day. You can use stock head bolts. But you will need to get a new headgasket sized for the bigger cylinders
