2010 510 SMR just replaced the clutch slave unit with the kit from toxic moto because my clutch pressure would go to zero, after the install I beeded it correctly and got about 4 miles down the road and it went to zero again any ideas? the only way to get pressure back it to pop the top of the reservoir and pump it untill I feel pressure again then another 4 miles or until I have to stop.
Is your master cylinder leaking by chance? I'm not familiar with the toxic moto kit. What comes with that setup?
Yup rebuild master cylinder, if its not keeping pressure its gunna be back bleeding into your resivour.
