So I’ve been trying to tune my vlx50 for the past couple days since it didn’t have any spark ever since the flywheel came lose. Got into the flywheel and clean the points timed it at 1.5 mm Btdc Started it and now it’s running backwards. I used a buzzeti timing tool to find the exact position. From my understanding when your too advanced or retarded ? Not sure what’s going on here. Should I try to time after tdc ? Also I have a 74cc airsal kit 15.15 del carb Doppler exhaust

Malossi variator.

The fly wheel spins clockwise I found tdc spinning it clockwise then I spin it counter clockwise to get my 1.5 mm btdc or it did it wrong ?

Tyler is right. The cam must have moved when you put it on.

Did you find the highest point the pin would move on the timing tool? Then lock it in with the set screw and then move it down 1.5mm?

Do you have a light to check it?

The Wikki does a good job explains it.

The bike runs forward. It is your understand of the concept of direction that is backward.

Cool glad it is running. I would probably set the timing lower to like 1.2 with points. But then again I am alway nervous with kitted MBKs with stock points. But if you not getting hot let it rip….and very cool bike. Definitely like those a lot.
