What's better TBM or RAD flywheel?

[infamy]

Magnets don't "wear out".

then why wont my hoverboard work??:shrug:

Then what exactly goes bad on them then?

So are Jetinetics the only ones that seem to go bad? I haven't heard of any TBM's failing yet or RAD's for that matter.

The RAD flywheels had a problem with the ring gears spinning lose and the center hubs cracking. Also you have to constantly re-torque the flywheel bolt as per the instructions or they come loose and the magnets throw the timing off a bit.

Thought I would add some pics to this topic. Here's a RAD side by side with a TBM and some weights for comparison.

Those are some good pictures and info you posted. :fing02:

Here's the weight for the Jetnectics aluminum flywheels. http://www.jetinetics.com/cgi-bin-j...spage&thispage=yamafly.htm&ORDER_ID=171634229

Matt, you are correct. Magnets don't wear out, but they can loose their magnetic charactoristics. Torr is correct, the f/w housing gets hot and heat is produced when current is present, let alone the crank and cases carry heat from the cylinder. Heat will weaken magnets. I have seen some Jetinetics f/w's whose magnets were very very weak and could not generate a strong enough field to induce current. This doesn't mean they all will, but if TBM's fail they are still in business, you can call them.

TBM also has screws in the cover plate over the magnets. I didn't remove them at all to look under but it looks like they may be more serviceable too if you can remove a cover rather than trying to get all the epoxy out of it like the Jetinetics to replace the magnets.
