It's a bit step buy a complete kit when master seal worn every year...
Someone knows if i can borrow a master cylinder seal from another motorcycle to use in my braktec master? Or some kind of o ring?
The problem is when i start the bike and put my clutch.....
Can be something related to hydraulic actuating....
The third problem is the radiator.....
Try to jump the temperature sensor (brass thing on radiator) conecting their 2 wires together. If fan start. Is the sensor fault.
I use one for MTB (MR pro Extreme) which offer more protection and since it is supposed to be used when pedalling, it not restrict any movement.
Look also for something from 661 brand
Used Brake fluid + water 50%/50%
let pipe full overnight.
or
Use a GLP gas torch to reat the front pipe untill it get red. But this destroy pipe finish.
