Default Real 80's?????

O.K.

Who has an 80cc engine, and can prove it with a caliper and some photos of bore and stroke measurements.

Doesn't Chris Hill claim he has a real 80cc?

I don't know, I'm just saying, let's get this on the table and clear it up once and for all.

I wish I knew, mine was stated to be a 80cc but who knows. Im not taking it apart until I have good reason. Then youll get your answer on this end.

Eventually.

I was hoping an importer or vendor would step up and show us the "80cc" measurements.

Please, do not include the combustion area as some have done in the past...

If those of you with an "80" can remove the head, measure bore and stroke in mm and report it here along with the engine kits name, we will start a pool of info here.

Don't sprain anything running out to do it, just next time you have the time or energy, and a ruler.

I'll do it this weekend when I get out to prep the bike for paint. Though, it's an older Dax, and he already says there is no 80

I have a new PK "80" on the way, but I don't think I want to pull it apart right out of the box...

I don't. And it's never a precise measurement of the true stroke anyway. I get something between 60-70cc, depending on how I hold my head.

I just chimed in here to see.....if anyone throws down the flag.

I'd be willing to bet it's 31cc +/- 0.5cc

Chris does not claim that his engine is 80cc. But most of these designators are simply model numbers, PK80, CH80 etc. A little misleading true and some less reputable vendors will stretch that to mean 80cc but there are no 80cc China 2 strokes. End of discussion.
