026 piston swap

[HVYTWR]

Does anybody know if you can put a late model 260 piston and cylinder (44.7 mm) on a older 026 (44 mm)

Is it worth the trouble?

If the bore is different, it will not work. Boring it out will mean a replate job.....not worth it. OEM 026 pistons can be had for around 20.00 or so.

Err... Teacherman - read the question again


Yes.. the larger Piston and cylinder fit and vice versa...

Will it give you any material gain? nope... different porting.

Why would anything need reboring for a 0.7 mm increase?

If I remember right the 44.7 mm was just an upgrade done when the 026 was still the current model so I don't think there would be issues fitting the 44.7mm P & C.

No problem, I have to read these posts twice myself as to not misunderstand. I'd imagine that would take a pretty good size hammer to get that in there without changing the cylinder
