Need new tires for mostly plowing and running around. Found some good tires.
specs call for front 26-8-12 Rear 26-11-12
Has anyone put 27-9-12 & 27-11-12 as more of selections going up on front and taller
Was given a 1997 Bayou 220 for free that had sat in the back of a barn for almost 9 years. Owner had parked it because his kids got too big for it, and they have other bigger bikes, said when it was parked it ran fine. He gave it to me as a trade from some networking I did in his home.
*Marvels Mystery Oil bath down the cylinder to free up the piston rings (I let sit for 24hrs)
*New battery as old one was shot from not having a charge for 8 years. I took my multimeter to the entire wiring harness and cleaned EVERY contact possible, as not even the headlights were working. After a few hours, everything electrical is now working. Headlights, green dash light, red reverse light (goes on and off with changing from reverse to neutral), and starter spinning strong (after a conversation with my mallet).
*Drained old oil (no glitter!) 2qts fresh oil with new filter.
*CDI was shot-- had zero spark and using a multimeter up the wiring harness everything was good up to the CDI—replaced with new one along with new plug wire and new plug now have excellent spark
The original carb was a total loss. I'm assuming it was parked full of fuel with the fuel switch on. It looked like they found it buried in the sand and put it on, it was so eaten and corroded my thumb went through it trying to get it apart—so new carb. I did also inspect the intake and none of what was in the carb made it into the engine, thankfully.
After oil bath, compression was still low—threw some brake cleaner down the intake and noticed smoke escaping from the head gasket—took the head off and saw the original head gasket was completely shot. Replaced that, and now compression is up to 90 from 50. I'm assuming, it'll need to go through a few heat cycles for the compression to really build back up (had the same issue with my 2000 Kodiak 400 from siting for 5yrs after a few heat cycles went to 180)
While the head was off, I did a leak test on the valves and liquid stayed, so no signs of gaps in the valves sealing. Also took a look at the piston and wall and both are in excellent shape, very clean conditions.
At this point, the bike should fire off or at least pop… but now that compression is back it's sucking air in though both the carb AND the exhaust pipe. Putting my hand on the pipe (no muffler) I can feel it sucking air in, doing the same with the back of the carb, I can feel it sucking air there as well. It isn't pushing air out anywhere.
I've checked timing and it's correct. The TDC mark on the flywheel is lined up with the spot on inspection hole. The mark on the timing gear in the head is lined up with the mark on the casting there as well, so timing is spot on. I don't believe it has a leak from the exhaust valve due to the leak test I did. I also don't believe a valve is sticking, I can see them both moving just fine when looking through the inspection holes.
In the past, I've had a bike have intake from exhaust and exhaust going out carb, but that was the timing being off, which doesn't seem to be the issue here.
Any advice on this would a big help as I'm stumped on what could be causing double air intake. Chances are it might be something simple that I'm not even thinking of.
At this point, I'm about to order a box of hair from Amazon Prime from all the head scratching going on.
Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.
Trying to see if there would be any interest in either or both of these groups. I was surprised there was not already a Polaris Club--there could be so many sub-clubs...
yay forum stuff again... really needing a 87 trx125 service manual.. if anyone has one without a dead link that would be super!
