Clutch Maintenance

Hello team - I hit a big log in a water hole that stopped me dead and bent up a tie rod. On the way home, bent the other one! No biggie, will bend them back to straight. Also tore the CV boot. So that will also get replaced. But while its all apart I should do some clutch work. Bone stock 2013 Outlander 650XT. 1500 miles. I removed the CVT cover. Everything is still very clean and belt looks good. Need to remove primary to get to one-way bearing. I'm familiar with snowmobile clutches but not ATV clutchs. They must be very similiar. What tools do I need to get the primary first sheave off? Can the clutch be split on the machine? On sled the entire primary came off as 1 unit and then was split. I have a clutch puller for a sled, worked on my ski doo. Will it work for this? Not sure if they are all the same. What tools do I need to do this job correctly? Any recommended sites to get them? I do have the service manual but thought I'd ask here first.

Should I get a new one-way bearing or just clean up and regrease. This atv plows my driveway, pulls a garden wagon and goes on the occasional trail ride. Its not abused or overworked!

Thanks!

Mrrpm vs Griffin performance

Title says it all. Looking to upgrade my 09 renegade 800 with one brand or the other. 975mrrpm bbk or griffin 980bbk. With there race heads or maverick heads. Stage2 or 3 cams. Looking for around 80rwhp on 93 pump gas. Got full clutches. Qsc stm combo. With full ron woods exhaust. Speaking outs load at the moment but this is the route I’m thinking about going. Not going to be a mud bike more like a gncc racer. Won’t be a sleeper with the cams I understand but tell me any info you have with something like this. Forged pistons would be a must because of the possibility of running boss nos shot of around 20-30hp for the scramble button. Figured 12.5 compression to be ideal. Anyone?

1998 Polaris 500 spark issues

Hi, my friend has a 1998 Polaris sportsman 500 that has had problems since he got it. I am the one who works on it. It ran fine for one ride but has problems since then. When I washed it after that first ride, it would not crank back up. It had very little to no spark. So, I replaced the stator and trigger coil along with wires (caltric) and it now has spark. It would run for about 20 minutes then foul the plug. So I adjusted the needle and it ran for longer then fouled the plug. (This is all at an idle no throttle) it obviously was having a spark issue. I re cut the spark plug wire to have new wire in the boot. I have been using a brand new plug and cleaning it when it fouls. I have tried adjusting the idle air screw. Unplugged and cleaned cdi to coil plug. The spark plug only gets a yellow to white spark. But the bare coil wire has a bright blue spark that can jump a half inch. I eliminated the boot as a problem by taping the wire directly to plug but it still gives a weak spark. This is all done with the correct plug (BKR5E). I have the trigger coil set as close as I can. Please help.

Air Intake Filter

Anyone ever add a pre-filter in air intake or would this be a bad idea? Would this choke off air? Picture is a pre-filter used on Ranger’s.

mega mayhem good for gravel roads also?

I do mostly forest trails where mega mayhems will work well, so my main concern is traction off road.
But sometimes I also do higher speed gravel roads (70-100 km/h).

Will the mega mayhems work ok for that also?

650 clutching

Sorry, probably been asked a million times already. I have a 2017 650 max xt and want to go bigger tires. Would like to go to a 28" because from what I can understand I won't need to do a lift, but will I need to reclutch? The bike is otherwise stock. Would like to go with a mud tire, probably silverbacks or mega mayhems.
