As far as which side, they don't need to be the same, or even syncd. I'd try 150/155 and maybe the needles on the 3rd clip. 25 pilots...

From what I recall from working on carbs, they're always from the bottom? So, 3rd from the bottom. That would make sense to me, which doesn't mean much.

      I've had this machine for 2ish years, has ran great up until winter. Sometime during then, I managed to break the exhaust right before the muffler. The summer before it had a hard time idling, but we fixed it by cleaning the carb, and messing with idle. Near the end of last year, the only way for it to fire was the have full choke, and full throttle, and the engine bogged down and you had to keep on throttle for 25mins. Over winter, the throttle had dislocated, and I got it back in place. We got it running, and all was good. Spring came along, and now it doesn't start at all. A fluid is coming out of the exhaust, and I'm told it could be water from over winter. I checked the airbox, and the air filter isn't for this quad, it also is barely sucking air. There appears to be little to no compression, based on this. I'm pretty sure the engine is flooded, as the spark plug produces a spark, but is oxidized. I don't know how the previous owner treated it, or when it's last oil change was. A bolt on the engine has either oil or gas seeping through it,abd was loose. I tightened it and it consisted. The engine is basically positioned in the rear, and it needs a good clean, I don't have a pressure washer, so I can get the built on dirt off. any recommendations on how to get the beast started again?

      Hi, All

      I started this project a while ago.. I have decided to make one thread I can continuously update..

      So , here we go. I got this Raptor 80 in really bad condition.. Rear end frozen, Engine toast, tires dry rotted, tons of rust..etc.. They admitted they beat on it very hard.

      Since they do not make these with a drive shaft anymore I decided to restore it from top to bottom..

      These are photos of when I got it home.

      Next up, the tear down..



      First, I needed to tear it down and determine if the rear end was still good... As we all know... That is where it would be cost prohibitive to restore if it is trashed..

      Got it completely stripped down and I lucked out... The rear Drum brake was caked solid inside with dried mud. That was causing the rear end to lock up. Took off the rear brakes and the rear end spun perfectly smooth.

      Once I got it all stripped apart I needed to take the finish off all the parts. I am going to be powder coating the frame and many parts.. Once the finish is off each part it will need to be sandblasted to white metal .. The guy I use for powder coating gives me a hefty discount if I bring the parts to him ready to go.

      You could just sand blast, but that would take a long time to get the finish off. First I used Aircraft Paint Remover.. That stuff is pretty toxic Goggles and Resperator are required. That quickly gets you down to the metal... Then you can sand blast to white metal pretty quickly...


      I had another thread I had started about a problem with the tear down... It has some great info .... here is the link... It is about removing the frame bushings. ....

      This is more of an informational fix I wanted to share..
      My Grizzly has been getting harder and harder to shift this winter and today was completely stuck and I needed to plow the few inches that came down this morning. First thought...oh no, tranny...but it’s winter and maybe it’s iced up. I pulled off the plastic to see what was going on and indeed I did find the drain tube iced up. 
      I took the blow dryer out and de-iced it. Quick fix, I never really thought about the shifter drain tube icing up before, shifts like new!

      Can anyone give me guidance on my issue. I have a 02 Grizzly 660 and replaced the wet clutch, primary shaft, one way bearing.  Today I was riding since I tested and was driving about 20-25 mph and all of a sudden the tires locked up, heard a screeching sound, and engine died.  Didn’t have a clue what was going on, decided to try and restart, engine turned over normal but engine hesitated slightly, started and had to assist with the throttle.  It seemed to do this for a minute then seemed to straighten out.  Got home, pull clutch cover and test drove to witness clutch operation and everything looks and sounds perfect.  Could not duplicate.  Please help.

      If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.

      I have a 01 raptor and recently had to bore it out to a 686 because it sucked in a bunch of sand. Now I have no torque or power in the first third of the throttle. I am hoping that someone else knows what is going on with it
