Hey guys, I have a 86 ltr250 I got for cheap. Runs an rides good but I'm not doing that any because it needs some love. Definatly lower on compression. I've owned a few two strokes but never have rebuilt top end on them. What is needed an or would a Manuel be best to go by being a newb to it? Lol. Also slight oil leak into stator cover so in gonna replace crank seal first. Oil is grey, is that my rings bad causing low compression an fuel to leak into the bottom end? Or is that the double lipped seal for clutch side? Idk if it's water or not, doesn't really smell like fuel either an I'm not losing any coolent. Help guys! It's much appreciated

its verry  simple procedure to tear the head and cylinder jug off. recomend a light bore of the cylinder an new piston and rings.  get the oversized piston  and have cylinder bored to piston. oil sel as for the leak in stator cove..

Grey oil as in milky colored? This is usually coolant and could indicate a blown head gasket, which would also account for the low compression.

Definitely get a manual. It can save you some agonizing problems like finding out the bolt you just stripped was actually a reverse thread (been there, done that).

Oops! Just noticed the date of the original post. Sorry.

      98 Polaris Magnum 425 4x4 speed limiter advice needed.
      By BillR94
      I suspect this bike may have a bad speed limiter. The part number for is 4060204. I found this one on ebay but it has a part number that is 1 number different. (4060203). It has the same LR44-2 and says its for a 94 Magnum 425. Will this one work on my machine or do I absolutely have to have the 4060204? Your advice would be appreciated. Thank you

      94 Polaris Trail Boss 250 2wd - Transmission Question/Help Needed
      By fixitforfree
      I have a 94 Trail Boss 250 2wd that will not go into forward. Reverse works great but forward just clicks but won’t engage. I’ve verified the shift lever is pushing far enough so I believe I have either an engagement “dog” or mating forward gear that are likely bad. I also see a fair amount of metal on the dipstick magnet. But if I ride the machine in reverse the gearbox seems quiet with no other issues by what I hear. That said I’m in process of pulling the gearbox to see what parts I need. The gearbox has 1341124 as the model number as shown in the photo below but I can’t find any gearbox on eBay or the Polaris parts site that matches that number. Is this 94 model a year that used some special gearbox? My tag on the box even looks different than all the tags on gearboxes I see for sale on eBay. I really want to buy new parts for the ones damaged in my gearbox to fix the one I have but just doing research at this point to see what gearbox I have to know which parts I need. Anyone with experience with this I welcome some advice or direction from what you have learned. Just FYI this machine is new to me but cranks, runs and idles perfect. It’s not beat up and will be a gem when I get this tranny fixed. Thanks.
