[Jimmy V]

Hello folks! I would be the new guy on the block 
I have a 1982 cb650sc and it looks like ill be changing the rotor on this bugger
do you need a puller of any type to do this or is there a trick too this task?
any help or ideas would be a plus in my book also i found a rebuilt for 145.00 could they come any cheaper?

You need a puller like this.

Check ebay for the parts I got mine for about $60

Yeah, eBay is probably your best bet. The 650s from 79 to 82 all use the same rotor. I believe '79 to 82 750s use that rotor as well. Basically if it's a Honda rotor with "slip rings" it'll work. Just make sure the resistance is around 6 ohms.

quick look on ebay found this one but it is ending soon.

you don't need a special puller to remove the rotor on a 650. the rotor has a thread in the middle and you can use your rear wheel axle, just put the bike in gear and screw the axle in and the rotor should pop off.

OK scunny
you got my ear with this technique would you mind filling us / me in a little slower?

[scunny]

ok hope we are talking about the same bit here, the rotor is on the end of the crankshaft. if your bike is together put it in 1st gear and screw your rear axle into the rotor(same thread) mine came out without much drama. I think the shaft is a taper so once you pop it all is sweet.

Rear axle trick doesnt work with All bikes as there are only 2 axle threads but 4 different rotor threads (depending on model--all in same model will be same)
