New to me 2015 300 TXT Pro Racing.  I have been going over the bike getting it ready, but I am new to trials bike.  The forks came set to max compression, and max compression damping (as in both adjuster screws were bottomed out in the forks).  Where should I set them to get a baseline?  My instinct says to put them in the middle (12-13 clicks) and go from there, but just wondering where other people are running their clickers.  I am about 170 lbs.

I've same bike, same year bike but a 250. Had it from new, the adjusters were set midway. No guarantee this is correct. You might need to keep check on the the fork pressurising during use, loosen the air bleed screws to release excess with the bike on its stand. Careful the screw doesn't shoot past you.
