Hey guys, I've read all the posts on closed loop and it seems there are a some people with issues with faulty afr numbers, codes, bad 02 sensors or bad modules etc. There are not a ton of threads on closed loop so I'm still on the fence but definitely interested in looking into buying it. Its...

Hi guys I have a 2007 attak 136 I just bought it. The limiter strap is an aftermarket strap. Should there be slack in the strap with track on ground and no rider? Right now my strap is taught with track on ground no rider but has slack with rider. I just need a starting point to get this rear...

What are your thoughts on cutting down a 137” 1.25 down to 1”? I ride mostly groomed trails, and speed runs on weekends....I will be using max spool 17 most the time in the trails and either max spool 20 or higher for races.....I realize the 1” will get me better speeds in the races I was just...
