Top heavy?

High lifter 3-5" lift, rhino axles all around, max radius upper and lower bars for rear, front forward arched control arms for front. 32x10x14 mudder inlaws

All going on 13 rzr 4 900

My buddies are worried about me being too top heavy and having issues with not being wide enough

Not sure if it’s cause they dont have money to do it to their machines or if I’m actually going to have a problem. Wife and Kids ride with me often, don’t want to have problems

2012 walker evans 800

Bough it new, April 2012, has about 900 miles now. at 4 miles had engine faure so i added the following just after purchase while fixing engine; team alba bb-kit, crankworks billet stroker crank (so its about 850cc), Muzzy exh and PC-V with AT. And has been flawless til yesterday. Wife was driving it since I bought a 900xp, anyway Saturday at near end of our ride check engine light came on, she said once got to 212* and fan didnt come on and yellow check engine light would come on, go back off, come back on..

Also seem to have a slight intermittent miss right above idle a time or two.. But mainly it did not.

I got it, floored it, seemed fine up til about 40mph seemed little sluggish….

Any ideas??

Does the coolant temp sensor in T-stat housing the computer reads, does computer use its reading for fan on/off switching too?

Also can someone point me to the thread that had what parts you could by to rebuild the driveshaft aka prop shaft (runs from transfer case to front diff) rear slip yoke is worn and lose/sloppy on the forward splined shaft.

Thanks in advanced.

Cam Phase Sensor!!

I’ve got a 2011 rzr 4 that i bought used, and the bike is throwing the cam phase code, but the only problem, is that there is no cam phase sensor on the engine. I know its supposed to be right above the oil filter.. The plug from the harness is just sitting there but there is no where for the sensor to go. The bike starts and runs and everything, just has a sputtering issue at around 3,000 rpm on take off. Any help is appreciated.

Just put on a Big Gun do I need a Programer???

Allright so my stock exhaust cracked at the muffler on my 2012 Rzr 4 800 and I threw on a Big Gun slip on eco. It sounds great but should I buy a programmer for just a slip on. As far as I know you dont need a programmer for "just" the exhuast only if you do more mods like bore, turbo, supercharge, alter max RPM’s….Let me know what you think!!! Thanks!
