Did a top end rebuild, honed .010 over, new piston, rings, valve seals, etc. When i re assembled i only had like 30 psi of compression but then after it sat all night i now it seems to have gained some somehow, there is much more resistance pulling it over and i even got it to fire for a few pops. Issue i got is that it makes a loud squeak noise through the intake i believe (goes away when throttled so something with carb area) and it seems to not want to run well. I took head cover back off and timing seems fine so im not sure if something is sticky and that's why i got some change over time or maybe the valve lash is messed up after doing all this, i did get another cam for it but i wouldnt think it would make enough difference to need to re lash. Any insight on next step would be appreciated, i will be looking up how to do lash on these because it is a very weird angle to slip a feeler gauge in.
Actually cam is slightly off now that i look at the picture, thought it was good while looking in person. Hmm.

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.

I rebuilt the top end on my 2007 Honda Trx500fe. It ran fine right after the rebuilt. But now when I try to crank it it blows Bach through the carburetor. I held my hand over the opening for the intake air and it blew gas back on my hand. Can figure out what happened all of a sudden. It was cranking and was able to ride it running through all the gears. Now can get it to crank just blowing gas back to the air filter. Need help again. Starting to think I should have walked away from this one.

'Gidday. An issue I can't find discussed already - my Bear Tracker selects into 1st gear fine. Selects other forward gears fine too but all above 1st gear are slipping. Can select reverse but nothing engages/happens.
Any ideas what I might be dealing with?
Cheers, Jim.
