Well, I can't tell from the stack of boxes what you have and don't have for it yet, but I can tell ya from the pics you're gonna need a piston/cylinder, new head, and bottom end bearings (if not a crank too), bare minimum.

Good luck, that thing is pretty fucking lunched.

...Come to think of it, the top of that rod looks pretty knackered too. Might clean up...

I'll take the exhaust if you let it go for shipping.


If funny how after 30 years these engines have barely changed.

I am keeping the exhaust. Just got to clean it up. Definitely not giving away a FMF pipe for free.

I have a new racehead, cam for the head, new racehead cylinder, crankshaft with bearings and the rod, piston, carb, jets, high flow oil pump, air filter, spark plug, 4 speed transmission, and other parts I can't think of. Only thing I am reusing is the case, some of the bottom end stuff, and the manual clutch kit.

The entire top end is getting replaced that's for sure. I am changing it from a 3 up to a 1 down/3 up. Can't wait to see how the 4th gear will work out.

probably by not grenading your motor from doing laps at the gap.

hey can you fit the 50 on your GS? :lol: just strap it on ride up... take the 50 for a spin... then load it back on the GS and head home! LOL

I think I probably could if I took of the passenger seat and secured it to the top box.

Well, the Chinese have knocked this Honda 50 motor off more than anything else out there, so it's become the standard powerplant for so many cheap Chinese bikes...it's become rather ubiquitous at this point...and while the basic design is unchanged, there is so much shit you can buy to hop them up, aftermarket.

If I'm not mistaken, this motor has been popped out as far as 125cc, in some applications.

Bigger 138s I have ridden.

I think there is even a 140 something kit

For sure, when you blow one up, you don't hold back!

I once added up all the mods you can do to a fiddy, and it came out to over $12K
