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.

Hey everyone!
Ya'll have been so great and welcoming to our new Ambassador program, we wanted to be sure that Quad Crazy was getting info directly from us about the Stay The Trail educational program too.
The program was started in 2003 with the purpose of educating the public about responsible trail use and fostering a sense of stewardship among OHV enthusiasts.
The "Where To Go" section of our website is another great resource for anyone looking for trail info. We host all of the Motor Vehicle Use Maps (MVUM) and overlay them on the Google mapping system. We want this site to be the place you go to for trail maps as you plan a run. The MVUM maps show what trails are open for what types of vehicles. If a trail is not on these maps, it is not an open trail.
We attend events and set up at trailheads throughout the season to ensure that folks are getting the info and education they need to be responsible on public trails. We have posters and brochures that quickly review these guidelines (all of the Etiquette info can also be found on the website).
Very soon, we will have a HUGE announcement about mobile mapping options!
Sam and Matt are going to be around on the forum, keeping everyone updated on what is new with the program and answering questions. Feel free to ask us any questions!
Oh – and don’t forget to follow us on FACEBOOK!

Hey all,
My name is Weston and I own a small engine repair shop in Pueblo, Colorado. I've only been repairing engines for 2.5 years so I still have plenty to learn. I look forward to learning from you all and pitching in on problem-solving when possible.
Thanks for the add!

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!
