Re-gearing after 3 inch and 7 tooth driver

[Imstuckagain]

I have a 2015 m8000 ltd 162 and am about to pull the trigger on the 3 jnch with 7 tooth driver. Just looking for info on how it will affect top speed, re-gearing from 19/50 to 21/49 if needed and hopefully someone who has doner his already can chime in! Only mods so far are the 2016 front end and skis, evo bullet and fixed post. Wouldn't mind hearing about any of the stage packages or clutch kits you guys are using either. Most of my riding is done in valemont. Thanks

I've been running a 2.6 and both 19/50 & 21/49, hard to clutch the 21/49, like the 19/50 better.
At the end of last year I was running 68g blue/pink primary 21/49, great for long climbs and lake racing, a bit heavy in the trees.
Going to run 3"Camo, 8 tooth drivers, 69g with blue/pink, tried 19/50 with 2.6 and 69g RPMs where a bit high, should be good with 3"
Stock secondary!

just my two sence

Is there enough clearance/ cooling with running the 8 tooth? IM half interested in running the 3 inch and 7 tooth and clutch as needed just to see. Should be pretty snappy in the trees, but the ride in im thinking you may run out of gear pretty quick. Anybody have any experience with the speedwerx or bikeman clutch kits?
