I am wanting to my cam cover on my '70 T120R. The bike came with a Boyer ignition pointless plate. I removed the pickup plate then pulled the center allen blot out that holds the ROTATING magnet plate to the end of the exhaust cam. How do I get the plate off of the tapered end of the cam safely? I tried running a 5/16" fine thread bolt into the threaded center of the Boyer magnet plate to try to push it off of the cam but I didn't want to crank on the bolt too much and screw something up. ALSO, is the piece KEYED to the cam or not? Thanks for any help! Heck....It's been in the high 60's to low 70's here on the Left coast. Getting excited to get the 650 back on the road! Chris

Note the rotor's position so you can put it back in the same place. Find a bolt like the one used to hold the rotor in place, but a bit longer. Screw that into the rotor. Give the end of the bolt couple of sharp raps with a hammer, and the rotor will come loose.


Stepping on others doesn't make you stand tall.

DaveP's method should be tried first ,
it works for most and is quicker ,
a sharp small rap usually Frees the taper
... but if a P.O. foolishly added locktite ,
you need a back-up plan
