I've messed with everything from stock to +6 on my serval dune bike. Stock arm was hard to do hill climbs with. The +6 arm was dumb and didn't handle or turn at all. After that I went to the +4 and it was a little bit better but the handling suffered badly. In the end I got a +2 and haven't looked back. It's got just enough extra length that it's fun on hill climbs but the handling doesn't suffer. A lot of guys buy a swing arm based on looks. Dont be that guy. You wind up selling the bike because you dont like riding it. Good luck. Sent from my SM-G965U using Tapatalk
I actually just kept using what I had and start the bikes more frequently. I have since switch to amsoil dominator and thinking about blending it castor oil.
I guess I should add before everyone has a meltdown that I dont reccomend doing what I did and I'm not saying it will be ok. I'm just sharing what happened to me and i should also add that I was using klotz techniplate.
I did nothing last year and 3 out of 4 of our bikes were froze. Went to kick and they wouldn't roll over. Kept pressure on the kicker and they all finally rolled over and fired right up. Never had an issue after that bikes run fine.
It's probably not shown because stock carbs have the tors and the tors delete caps are different. Hit up west coast atv parts or south Texas banshee. Or just about any sponsor. They will get you a gasket.
