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.

Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves. From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match. I have no idea what this would cost.
2. Buy a replacement head+cam+valve cover.
#1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option. However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number, 11100-19B10, instead of 11100-19B01 like for all earlier models. What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years. Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical. Would those work as well possibly? I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on. Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

The studs in the sprocket hub are stripped out. The hub is probably walloed out also. Probably will have to have a new sprocket hub. I doubt I have the ability nor the tools needed for this job. Thanks for all suggestions/opinions!

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!
