I finally figured it out! It was the valve lash. At top dead center, it's. 006 for intake and exhaust valves. The motor needs to be at top dead center. On this 550, that's when both "|" marks on the camshaft gear are parallel with the top of the head, or otherwise horizontal. It started up...

I have a 425 that had broke a timing chain and bent the intake valves. I ordered a new chain and valve set. I was wondering how I line up the chain with the sprocket on the bottom end. The cam chain has 3 different colored links that I have used before to time the engine. There is a timing mark...

New to this forum as this is my first post and just want to say thanks in advance. I have a 2014 Polaris Ranger 900xp EPS (1,500 miles) that I brought a few months ago and everything has been running fine except for the usual Crank Position Sensor code, but about a week ago i loaded the bike on...

I have a '96 Trailblazer 250 that I'm in the process of completely rebuilding. I got it trashed, and with many parts already off of it. The issue I'm having is, aside from installing the new stator using the marks on the old stator from the bolts for position, how do I know if the stator is...

Our 03 sportsman 400 was left untouched for some time so we took it to a local repair shop to get it back in working order. When we got it back we drove it not more than 5 miles before it started smoking, turns out whoever worked on it forgot to put oil back in it. The piston and rings burned up...

Timing Chain Broke! On my 1999 Sportsman 500 the exhaust lobe on the cam was worn down completely. I replaced the cam and rockers. Set timing. Set valve clearance to .006 at TDC. Fired it up and it ran beautifully for 20 seconds. I gave it throttle and once I got to half throttle... "Snap!"...

I just bought a 1992 Polaris 350L 4X4. When it starts up it idles fine, but when you rev it up it seems to bog all the way up through the rpm range, slow climb to rpm as well. I know the previous owner said he changed the carb and thought he may have the wrong one. Any ideas? If you put the...

Just finished with a top end rebuild. Rebuilt the carb. Put a new pull in. It pulls smooth and seems to have good compression. But nothing fires when I pull the rope start. pulled the plug and checked for spark. It fires very time I pull the cord.poured fuel in the cyl. and got it to fire one...
