Good question about the epoxy . Really I have no experience with it at all. just have seen many sine waves on cars over the years . I talked to My sales guy in china ,he said they machine off the old tab and gas weld a new tab on. appears the magnet is mounted inside the outer flywheel housing. I am thinking a couple mig tacks on each side should do it

.

Gas welding is a good idea, since the heat will be much lower. That said, a couple of MIG tacks would only produce short bursts of heat, and the flywheel should act as a giant heat sink. The good news is that flywheels are cheap as chips from China.

If I could just get china to make flywheels with 50btdc tabs ,without needing to order 1000pieces. I do want to see how the timing acts with the carb in place before starting to install the injection . That should be interesting

Does anyone know what flywheel puller I need for this 167fmm . It is completely different than the 200cc flywheel. Externally threaded hub

You could be correct it measures 28mm on the out side of the threads ,but I was not sure 28mm would be correct or if 27mm down in the threads would be correct.

I recommend that you ask in the "Hey Humanbeing" thread. He'll know the characters to search for.

I saw the 3 Bolts and thought , I already have this tool. Hopefully you can get the idea, tab runs 15-35 degrees.

Thank you Humanbeing. looks like there's a winner.

Thanks HB!

I searched those pages and found several different pullers that I'd like to have.

Me also Thank you . Beats Snap-On prices .

I decided to weld on a timing extension. The case of the flywheel did not mind at all . I did not have gas ,so in used flux core on the mig . I needed a way to smooth it to a true radius and missed a craftsman 101 6 x 18 metal lathe for 300 dollars and 4 miles from my house . 3 Reasons , not owning a truck , being lazy tired after work Thursday and Friday, then thinking I had time to wait for my wife and her Saturday chores . before I took her ford edge from her . I ended up putting a abrasive disc on the table saw and careful fence setting to grind the radius. Not the most beautiful timing tab , but the bike runs ,with the carb still at this point . So about the extra timing with the carb in place . The bike seems to rev freely and pull harder in all gears . With my current gearing of 15 and 45 18inch rear dirt wheel. riding at 7000rpm it still has good pull with no complaints to 8000 @60mph across the board it feels perky . Oscilloscope will tell me if the timing tab is good enough for the Fuel Injection .

Good thinking. How did you attach the tab to the flywheel?
