Gota love those air cooled motors.

giving the honda nearly a full face lift. about half done with it so far. one more weekend and the grinding should be done. i dont expect 80hp but it should run very well with all things considered and match up great with the cpi pipe . nothing ventured nothing gained

I posted it because the Crankshaft is turning opposite to the way it should be going

my dad had a cr 250 with a snomobile ignition jimmy rigged on there, and it would sometimes get going backwards... my uncle borrowed that bike and was lined up to race his friends, and launched backwards down a bank, wish i was there

My kids have started there CR5 backwards before

Bloody IT's, mate had one. Dammed if we could start the bike earlier it was a 200. put it in the back of the ute and tied it down. Driving along the road and it started, must of moved a fraction and bump started itself was wheelspining backwards at full revs

Fucking freaking, never seen anything like it. Nobody believes me. i know what i saw. No i dont smoke POT


anymore

cant talk about specific port timing or discharge angles or time area but heres a pic

Looks tidy, just don't leave a wide exhaust perfectly flat across the top

put a fair amount of thought into this. should be headed in the right direction for the type of power i want. if changes are needed theres still material left.

atleast the cylinder wall doesnt look like this...

holy crap is that picture big, hahahhahahha

What the fuk !!!!!

Are you showing us a pic of your cyl wall finish or your port work !!!!!

All i see is the corner of your exhaust port if your only going to show one pic atleast make it a good one!!!!!!!!














































































Or

























May be we don't want to see it????????

whats all the pitting on the lower left corner of the exhaust port ?

its not pitting. its filings from grinding.

billybob theres nothing to show. no secrets. no magic shapes. looks alot like the stock port with slight bigger area.
