Hey thanks guys....

Well, after setting the float height of 27mm (as per manual) I wasn't able to start the bike. I read in the manual this could cause a rich condition that would prevent the bike from starting....

After turning the fuel on and pulling the choke, I lightly kicked it 3 times and tried to start it on the 4th kick. It sounded like it back fires through the exhaust...not like a fire cracker, but more of a sound like pulling the trigger of an air gun.

I then, advanced the timing a small amount, and retarded it a small amount but nothing.

I checked the plug and it's wet. This is after 5 heat cycles and 2 very brief rides in 1st gear.

Could this plug be fouled? I do have another one...



And the exhaust (no baffle material)...which could need to be blown out being it's a rebuilt engine.

Just took the reeds out....they have fuel on them also....

Question....should the reeds be easy to open if you push on them with your fingers from the inside of the cage?

So I adjusted the float to where it was originally and added a little more. Now there will be less fuel in the float bowl.

She started on the third kick and ran and idled good.

Shut the bike off, and was able to start it on the 3rd kick.

Shut it off and was not able to start it.

I changed the CDI to my spare but no go.

Plug was wet again and it backfired while I tried to start it.

I'm ordering a new set of boyesen reeds to rule that out.

another free thing to try is, take a piece of sandpaper/scotch brite, and clean all the contact points on the frame...and make sure all the connections are clean and not coated in green corrosion, and use a little dielectric grease on the connections.
