I did a compression test on my 2005 Bombardier Traxter 650 CVT and it's 75 PSI. service manual only talks about leak down test. No specification for engine compression the manual. What does 75 PSI tell me? Thank in advance.
A little history of this machine. 640 miles. Picked it up about 2 years ago, not running. Probably the computer. Tested all circuits and confirm it was the computer. Long story short, I watched a Youtube video and fixed the computer. ATV now started and runs. BUT, it tops out 20 MPH. I cleaned the carb 3 times also using a Mikuni carb kit after the second time. Slide in carb is going up and down. Only adjustment for fuel is at 1.5 turns out. NGK Sparkplug had soot on main part but brown on the electrode. Champion sparkplug is brown. I check CVT clutches and they both appear to engage like they suppose to. Checked valve clearance it's 0.00, I can't get any feeler gauges in-between. I check timing chain I believe it's in the correct position and hasn't skipped. I removed muffler plug and drilled into muffler to try and make sure it wasn't plugged.

Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

polaris 2008 50 outlaw automatic: got the 50 for free. would only run with chock on, replaced the carburator with new. I can't get the unit to an idle where the machine doesn't move forward. if I do get it to idle down within a few moments it will die. got something to try?

Just bought a non-running 425 Magnum 6x6. Guy said previous owner had motor rebuilt (3 years ago or so.) It reportedly ran great but recently the electric start began failing and he put a new recoil on it which he broke immediately.
I get it home and put a new recoil on it and the pull is incredibly hard....so much so that I think I'm going to break the new recoil assembly. I also installed a new starter which won't roll it over either.
I'm thinking maybe a hydro-locked situation so I pull the plug and the motor rolls over fine with both pull start and electric start. The cylinder was dry however.
Checked the valve lash and it was right on at .0006".
Checked the compression relief spring on the end of the cam and the spring was strong and keeps the metal piece against the dowel like it should. The cam lobes look good from what I can see.
I have a small camera that I dropped into the cylinder. Could t get a pic of the entire chamber because of the angled engine but there are marks on the center piston and a couple of grooves once side of the piston top. I will include the photo.
Anyway....I'm at a total loss at this point. Not sure how to proceed and diagnose. Would sure appreciate anyone's help who might know what the heck is going on! I was able to get it to turn over about 5 times with electric start with compression tester installed which read 145 lbs. I don't know what else to do!
