Make me wanna buy a Jog now though. Read somewhere you can bbk them to almost 20hp. Thats bloody nuts, the nuts I like to be.

no you have it backwards. They are ten times a OKO. Oko's are seriously the cheapest carbs on the market for a reason. You could get two, and one would require a bigger Mj than the other. THey suck, ask anyone who has ran them both. The oko probably cost $10 to make in china..Think about that one

I wasnt saying the polini is bad it just lookes like it in pictures, i personaly prefer fuel injection over carb so I dont have a full grasp on the brands but polini seems to be the most choosen.

Spark plug turn out nice color after 2nd run.

That jog is gonna tear a**! Always been my favorite bike! Just cant find em on the mainland, not Or anyway.. you gotta stop by motosource and show it off, they'll really appreciate a bike and build like that. The owners brother took my Razz from 32 to 50 just by modifying stock and adding a carb! Good set of guys.

Japan tail came in mail today.

I did compression test.

Today, I put in the new bore top performance blk trophy ,ran stock carb 14mm 48 pilot and main jet 110 32:1 premix. I rode 5 miles and runs great!

I did 30 miles riding since had a new bore and check compression last night. It had 164 psi on cold engine before riding my jog.

motor still going strong had 50 miles on it , i did wide open throttle 1/4 miles. reliable 1 kick start , motor runs..

Greetings:

Hope you run race fuel or AvGas.

im using 92 gas tesoro, 76, chevron.

Hmm, don't know if a drop from 171 to 166 is significant or not. Hope it's ok, but I'd add a gasket or trim the head to lower compression to 145 if it were mine. Either that or race fuel.

compression 171 is polini corsa w/ oring corsa cylinder head and oversize malossi piston 47.8mm, base paper gaskets

Compression 164 is top performance black trophy, asso 47mm piston, both aluminum gasket.

Greetings:

I'm just not sure if even the precise, high-quality Corsa can survive with that compression on pump gas.

corsa bore still can handle on 92 gas.

Here is my daily riding.
