me again flywheel issue 425 magnum 4x4


Recommended Posts

I also have a magnum 4x4 that I am working on it is getting a new piston, In the tear down I pulled off the flywheel

and found that all the magnets are not attached? why does this happen? there all in good shape so is it possible

to reattach them to the flywheel? I can buy a different flywheel, but it looks like around $300 or more and one of them on Ebay

looks like the spacing is off a little so it may have the same issue.

the stator looks good also

That sounds like badly made really.. Can you see how they were held in ? Some bikes the magnets are glued in and some have some sort of clip or blocks of hard rubbery stuff between the magnets holding them in.. I've seen cases where on magnet was loose.. but never the whole lot.

I don't think I'd try repairing it though.. to much potential for real damage if they came off again, smashed the stator, broke, and went through the engine.

Perhaps there is a problem with them.. and perhaps there is a superseded part.. I'd check the genuine parts supply, and check for warranty or recall info....

I know nothing about this bike, I got it tore apart with the piston stuck in the jug, but it came with a used jug and a new piston and rings.

it's a 96 with 112 miles on it, well that is what the odometer says it's a 4x4 with real good plastics with nice tires my best bet though would 

be to find a new engine for it I think that I would have less money into it going that route, because I am not sure of the parts that I am missing now

If the pistons stuck because of sitting it might be ok.. usable even.. If it seized from overheating and then got parked.. not so much..

Soak it is something.. diesel even does a good job.. then pound it (the piston) a bit with a wooden hammer handle, or solid dowel and hammer (one pound).. It'll come free.. Free the rings in their grooves carefully then take them out and and clean it all and put that top end back together.. It will be good enough to test the rest of the bike.. Then you decide whether to do more repairs or not..

That's what I'd do.

Ah.. Gwbarn beat me to it..
