Starting to look like something

[wret]

Getting down to the finer details.

Got the drive chains on. Looks like everything lines up perfectly and no half links needed. Sometimes you get a break!

Got the faux oil tank / battery box about done.

Great looking bike & again I say I love this build!

 

[wret]

Thanks guys!

Got a little bogged down with wiring over the weekend. It was sweet to hear the engine turn over! It will be sweeter when I get a spark.

OK, I've to to admit I know little about these engines anyone know where these things go?

1. Crankcase vent?
2. Extra vacuum connections?
3. Open port on cylinder head.

I made a considerable amount of progress over the weekend. I got the basic wiring done. Cranked the engine. Got spark! Connected up the carb and poured some gas in the tank. Turned the engine over and vrrrrrm!!!

I still have quite a few things left: clutch, brakes, shift lever, lights, but getting the engine running was a major milestone!

Anyone have any experience with Mukuni carbs? I'm a total novice and documentation seems to be hard to find.

 

[Mr.B.]

I think they're good carbs. Very adjustable. I guess there are "real" mikunis and copy mikunis. The real ones have a larger float bowl and slightly different body shape. Seems like most people use the copies, they seem to be fine. The jets are different for the copies.

I found that you do need to experiment with the main jet size and pilot jet size to get smooth performance through the entire rpm range. Once you get the right jets, you're golden. I run a vm22 on a 5hp briggs and Honda 190cc. With your engine maybe larger, like a 24mm would work well.

Affordable Gokarts's website has a mikuni tuning tutorial, very helpful.

I got her running well enough for a trip around the block today. Only runs with full choke though. Definitely in need of some tuning!

First check for air leaks between the carb and the head. Often a manifold will distort and suck air in down the sides of the gasket.

Well the dual pull kit I had ordered for the brakes fell through. The manufacturer was out of parts. Probably just as well as I would have had to modify it to work with larger cables, but I had to ditch the brass lever. I found a dual pull lever sized for heavier motorcycle cables. The scooter style cables were a pretty good fit too.
