Rzr 900 xp coolant issues

Ok guys i relocated my radiator to rear. Ive tried bleeding the system numerous times and keep getting air. It also keeps filling up the over flow bottle. Do these factory radiators have to be filled from the bottom hose or am i missing somethig here? I put the fill in the upper hose bc i didnt think it would make a difference. Thanks in advance for help

800 rzr 4 duraclutch…

I came to this forum looking for some advice on clutching for my rzr 4. I put a 3 inch lift on with 28" bighorns on beadlocks on and the stock clutching immediately let the belt start slipping. So I ordered a epi sport utility clutch for 27-28 inch tires and a new gates carbon belt for it, installed it and about 4 hours into riding at my farm it started slipping. The epi clutch I was not very happy with and was a complete waste of money. After doing some research on here it seemed that Todd from Hunterworks was the man to talk to. I pm’d him and got his advice he turned me towards the duraclutch. I installed it today and have yet to take it on trails but from just driving around the yard this thing is so smooth it’s unbelievable. Todd is a stand up guy and was emailing me back and forth on a Sunday night at 10pm, now that’s customer service. I will report back how well the duraclutch does at my farm this weekend and how it does at windrock Oct 17-19th as we have a trip scheduled to go there.

Fuel in Valve cover?

I recently bought a 2008 rzr 800.. They guy told me it had a holz top end about 40 hrs ago… It’s has a dual looney tuned exhaust and a power commander 5 and is snorkeled straight to the intake with a uni filter… It started blowing white smoke the other day and a rattle near the valve cover and it’s always been hard to idle when it’s cold… I reloaded the lte map and it still didn’t fix anything …I have since pulled the valve cover and it smells like gas.. I pulled the intake and there was some black soot on the flap… Any suggestions before I go deeper into the motor?

Xp transmission oil

Has anyone used honda vtm-4 differential fluid in their transmission? It has the same consistency of the polaris agl fluid, but red. Here are a few pics of the honda differential and the oil recommend. I have 2 gallons left after I sold the ridgeline.
