Beta Sincro Snatchy clutch...

Has anybody found a cure for the Sincro light-switch clutch yet? 

I've tried several things to fix it:
1. Changing the pre- installed settings
2. Changing the oil
3. Slipping the clutch in high gear to wear it down

Despite this, it still snatches in slow turns, so I can't keep a line in a tight corner.

Basically, I spent £7,000 on a bike which is not as good as my old one. Absolutely gutted.

Hi 

I have no experience with a Sincro, but looking at the diagrams on the Beta website it looks to be very similar to the enduro clutch as below.

Although it has pressure adjustment via preload on the disc spring, it still has friction / steel plates in a basket like the EVO.

However I have owned a few EVO's and the clutch on those was often grabby. Many people modified the EVO clutch plates as video below.

This is a pain of a job, but does help. Maybe worth trying as it is presumably the friction plate engagement that is the issue with your bike - unless there is a faulty / out of tolerance part(s) fitted to your bike.

Putoline GP10 oil with frequent changes also helps as other oils I tried seemed to induce clutch drag.
