Runs pretty well with the kill switch turned on. Anyone know about the fuel delivery? If he could get rid of the primary chain slap it would REALLY be nice.

Not sure it is chain slap.  Check out the write up.

It's mine!

Someone saw the kill switch! wow :)

I will have to replace it,the reason is simple,since I removed the electric start I also changed the left control for a model without the start buttom.The buttom must be in OFF position to give positive to the coil,the control is from a small bike that didn't use a battery for the coil.I will have to replace only the contact Under the red buttom

It's a chain slap.It's the primary chain,reacting to the vibration of the ''V''.The 400f use only slider for the primary but for mine a tensionner would be better to remove play in the chain.If maybe a day I have to split the case I will work on it.  The good is the chain rattle stop with 100-200 rpm increace.

I have 2 carb mounted Under the tank.Ok I know I lost power.....but that's the last of my problem,it's a show bike,it run and it's perfect.And they fit Under the tank,so I keep a stock look.

Aside from its awesome engine, this is also a really nice looking bike. I am amazed.
