What is your comp and reb in the rear set at? Also have you changed geometry at all? You mention it's "twitchy", can you elaborate more? And when the bike slides out are you real heavy on the throttle or are you just cracking open the throttle or maintenance?
Also when you added preload to the spring did it make it better or worse?
Well basically theres a set of bends near me where i take all my bikes to get a general feel of their handling.
Straight away as soon as i was leaning the bike over it skipped out at the back a couple of times which i thought was odd on both nutral and full throttle.
Put it down to cool weather and standard tyres.
Then i went round a roundabout with my sc2 tyre on and with nutraul throttle on and it slid out again.
I ignored it and kept it cranked over and it didnt do it again.
Then a slip on the power out of a corner.
Also with the sc1 tyre on even when warmed up the rear still breaks traction momentarily which all in all means i am now nurvous on it and cant get my confidence anywhere near where it was with the gen 1 i just sold.
Im not sure on comp settings as im just playing around with it trying to make it feel better.
Its feels better in other areas since ive stiffened up the rear spring but the edge grip seems to still be and issue
