Rotor

[sternavi]

Hi
I cant take off the rotor bolt,I put iron bar inside the rear wheel in first gear
with no result,what you think I need to do?

Get a shop manual and read the instructions. The normal procedure is to use special tools such as a rotor holder and rotor remover. Why do you need to remove the rotor?

If you're talking about the rotor on the end of the crank that spins inside the stator... you can remove the bolt with an air impact wrench (it's a normal righty-tighty lefty-loosey thread), but you absolutely MUST have the proper special puller tool to remove the rotor from the crank.

Subtitutes made from spare bolts are just heartbreak waiting to happen...

If the "rotor" you're referring to is the electronic ignition rotor on the right side of the engine, make sure you're trying to loosen the right thing first. There's a 12 mm hex head bolt that is removed first. It's threaded into the end of the crankshaft. Then under that there is a 21mm hex "WASHER" that just pulls off. So unless you first remove the smaller bolt, the hex washer isn't going anywhere! That washer just helps retain rotor and ignition advancer while at the same time provides a convienient way to turn or hold the crankshaft. If you try to turn or hold the crankshaft with the smaller 12mm bolt, chances are pretty good it will break.
