You are absolutely a fantastic mechanic. It amazes me how well you work on engines. Partzilla should be proud to have you on staff.

Was wondering why you put tdc at the case halve and the service manual says to use the cps sensor hole as the guide? Seems that your putting yours 90 degrees off per manual. 900 and 1000 difference?

great videos but I aliens my rzr 1000 with the way you showed to get it on top dead center and my number one piston was about half way up to top so I was wondering if maybe the 1000 timed differ ant than the 900

I just rebuilt a 2015 Polaris ranger 900 and did a bench compression test and found 145 psi on one side and 45 on the other could the shims possibly be the culprit? and where can I purchase the shim kit. thanks

Hello randy. You may have a tight valve or two, which could be a result of incorrect valve lash. Here you go! www.partzilla.com/parts/search/Polaris/ATV/2015/R15RTA-E87+RGR+900+XP+ALL+OPTIONS/ENGINE%2C+VALVES+and+CAMSHAFTS/parts.html On this unit you will have to replace the entire bucket to adj the valve clearance.

Hello Joe. This is normal. What you are looking at is a build up of carbon.

I am wanting to buy a polaris Rzr 900 xp that a guy is selling for 1300 but I am afraid of not being able to do the rebuild; last time I went and looked at it. The guy said it ran but was knocking, so we got it started but died on us three times, the third time, starter wires got hot and we noticed it was locked; Whats your opinion? Thanks very excellent job. I have watched the videos a lot, trying to memorize the procedure.

Question I'm redoing my pistons and rings would you do a valve job also or just adjustment if the head seems to be in good shape. Also what's your take on converting my razor to the big bore 935cc kit
@PartzillaParts

Pull the valves (make sure you number them), clean off the carbon, and take a look at the seats. Also check out the seals to make sure none are hard or cracked. Be careful when modifying an engine as there is always a price to pay for higher performance. Hence why we had to rebuild this one.

Did you torque the cam caps when measuring valve lash or can you leave them snug, measure then torque when complete?
@PartzillaParts

Snug, you don't have to torque them down until final assembly.

Great video. I had a question on the cam sprocket bolts. I noticed in the service manual for 2013 RZR states to use new bolts for the cam sprockets (assuming because they come with a thread locker pre-applied). I recently did the valve timing on my 900xp motor and did get new cam sprocket bolts x 4 but realized that I had to remove the first two bolts (exhaust and intake) then the timing chain jumped while rotating the motor to reveal the next two sprocket holes. On the second try I got everything lined up and put the first two bolts back in (exhaust and intake) then the second two bolts fresh from Polaris. I did ensure everything was torqued to spec on the cam bolts. Should I be worried about the first two (re-used) bolts working loose? I noticed in this video the bolts were removed from the sprockets and put back in without thread locker so maybe it's not a big deal? Would love to hear your thoughts. Thanks!

The manufacturer always recommends replacing the bolts because they will stretch over multiple tightening. You should be fine if they are torqued correctly.
