My first guess is the carb took a hit and disloged the assembly. Check for air leaks at the carb to manifold and manifold to cylinder.

i think it was as simple as an air leak, i went to pull the fuel line off and the whole intake manifold was super loose, not sure if it was this morning or not, i didn't check.
and i think i got the leak around the petcock (hopefully).

i'm going to take it out again here in a bit to test it and see if that was in fact the issue, i took the head off and there was a bunch of un-burned gas/oil on the piston and in the cylinder so my bet is that the loose intake was indeed the issue.

it could also be that the float is stuck open and the fuel is just overfilling the float bowl and just running into the crankcase and the cylinder

Default Re: what did you do to your motorized bicycle today?

Just did some more transfering parts off the old mountain bike frame to the new one... I still need to get a wide 3 piece crank set for this one and I'm going to need to make a set of billet mounts since the frame tube is too wide. I'm also going to need to get a few more spacers for the head unit since this one is a little shorter than the other one and the stem won't sit all the way down like it's supposed to, but a 1/4 or 3/8" spacer should make it fit just right.
This frame is a little bigger than the old frame but space will still be pretty limited. I did a test fit by setting an engine in the frame so I know it'll have a little more room than the other one but not much, There shouldn't be any problems using a shorty intake and an 18mm Mikuni or a 21mm Dellorto. I'm going to try and use the Super Rat engine I built in this frame but the front mount bolts are too close together for the frame tube to fit in between so I'll either make a billet mount or see if I can open up the billet mount I already have enough to go around the frame tube, the one I got is about 1/16" too small so I'm going to try and use it before making a new one.
This one will get the Super Rat engine I built a few months ago along with a CR80 pipe and a 21mm Dellorto PHBG carb since that's what I got sitting around at the shop. I may try and get an Arrow reed and do the necessary cylinder and piston mods but I can still make this one plenty fast as a piston port. This one may go back on hold as I get closer to finishing the road bike, but I got some good progress on it tonight.

Here's an idea of what this one's going to look like...
