bought some chinese short CNC levers for my monster... all ok for a short time but then after being stuck in a traffic jam, the clutch started slipping.... was a real pain to get home.  Damn, clutch repair needed I thought

did some digging around on the net...turned out the CNC levers sold on ebay from chinese sellers is the problem..many other bike riders had the same problem....... switched back to the original OEM brembo levers.... all ok and no slipping....

my two cents but avoid chinese CNC levers at all costs!

Had a customer with a Busa who got very cheap billet levers. They rattled to the point of falling off. Shocked He got Pazzo or CRG after that. Wink I have worked on Chinese dirt bike, once.
China makes great stuff if they want to.

mr freezer...hmmm... did you adjust the screw that pushes the pin into the master cylinder? if so, all the way in is better?

the levers look fantastic and it`s a shame to have them sitting in a drawer in the garage....

Spike in PDX

I fitted a set of the folding version of those and they worked fine. I was bothered by the looseness of the joints, though, so after scraping one up a bit (it still worked fine) I replaced them with a set of CRGs. Functionally the same, although the new ones are more aesthetically satisfying!

You need to adjust that screw so there is 1.5-2 mm. free play.  Less and clutch slippage can happen.

sorry but do you mean free play before engaging the levers so that ` at rest` there is such play before putting any pressure on the pins that go into the master cylinders?

Free play - the amount of pull travel before the lever actually starts acting on the piston of the Master.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the air—these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

May the torque be with you

I can personally contribute to this conversation.

Installed some of these a while back while installing a new clutch slave and oil change (They were CRG knock off's)...Long story short, even with proper clutch lever adjustment and bleed, there was still slip after the install.  Now I was only experiencing slip at max torque and at hard shifting. I can only imagine the geometry of these Chinese levers isn't exactly right.

So after a bit of confusion and frustration, I say "Why not put the old levers back on?".  I mean why not right?...well sure as shit that fixed my clutch slip. Go figure.
