might be of interest to someone?
I have not used this service so this is no reccomendation. I just thought it may help someone out.

might have to check this guy out...i have a 5 gallon bucket of these things inoperative...i end up using motoplats...

what is the general opinion on the sem versus motos? my original sem setup went bad on my 88...made it misfire and run backwards...really bizarre.

i notice the lighting output seems alot stronger

My 430 (88 see avatar) requires at least 5 kicks when cold I am looking for something that gives a good spark when spun slowly?

I had good results from the SEM on my 84 240 in 84 to 89. No problems. was told to continually clean the unit btw rides to allow it to remain cool. Lots of punters had problems, i got a good one...

I forgot! i borrowed a 83 240 to do a race and the magnets flew out! very expensive noise!

Put a chinese coil off a thumpstar and a CDI off the same.
Time it with a battery powered strobe.
Total cost less than $25 aud.
The CDI uses a lower trigger voltage than the Husky cdi and makes starting a lot easier.
I put a post on here somewhere [ with photos ] but can't find it now.
I have this setup fitted to both my 240 and 400 and it has run fine for over 2 years now.
I do have a deco valve fitted to the 400 which helps a lot.

Found that pikky

Looks pretty slick. dies your grinder have a lug so it can be clamped in the tool holder?

Na just a piece of pipe with a bit of flat welded on and a bolt to lock it in.
Rough as guts but works fine
Have done 3 flywheels now and all work great.
The tapered mandrel is special and I spent some time getting it right.

I like it. So let's hear about the mandril...

 

[dukkman]

Mandril runs between centers and the inside of the flywheel runs true to the taper.
The outside of the flywheel is all over the place and is scary to watch when spinning.

I grind some magnets away , about 2mm dia/ only on the generator , then epoxy the generator magnets and grind it back out to the original dia.
This looses a little of the magnetic effect but the generator has heaps to spare.
