Cg250 Flywheel threads.
 

I have been searching for a while to find this answer with not much luck. I need the thread size for the flywheel puller. From what I could find I believe it is an M27 left hand thread, but if anybody can tell me for sure I would appreciate it.

Ok, so it is an M27x1. I will order this puller as it appears to be the same as what you linked. https://www.ebay.com/itm/1pc-Black-M...-/352663054759 Thanks for the response!

I have that tool used it on CB engine Yamaha TW clone engine NC250 engine etc
You’ll do fine with that!

That's what I wanted to hear. Thank you sir.

So does this mean the cam swap is about to began??:clap:

Shouldn't be necessary for that, perhaps the crank is getting swapped out, or maybe an EFI kit?

I do plan on doing the cam swap here soon. I figure it is worth a go before I decide to just move on. I have other more useful plans for the money I would be spending on the GTO, so I may just hold off.

In order to get the cam pin out the flywheel most likely has to be removed. If not, great, I still want the tool anyway.
