I'm working on a 2002 Polaris Sportsman 400 with shift indicator problems. The indicator panel only will show Neutral and Reverse. If it's in High or Low, the indicator will show "R".
I have replaced the three position indicator switch on the transmission. There is also a two position switch on the tranny that I didn't replace. If anyone is familiar with this problem, please let me know what I need to do. Any help is greatly appreciated!

Hey everyone,
I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

The clutch engagement on my 2021 cforce 400s was approx 2700 RPM, very abrupt/not smooth. I obtained a "kit" from RNG consisting of a blue painted spring (spring force unknown) with 12 gram weights, as measured on my postal scale. Installation was easy; 18 mm and 30 mm (not 32 mm as seen on other writings) impact sockets for clutch housing removal. The resultant clutch engagement was still up to approx 2500 and very abupt/not smooth.
The original spring was labeled p/n 0951-1021 (specs for spring force 300/1600) with 18 gram weights.
I called RNG who told me the kit should work fine for my ATV, but that wasn't the case as I found.
The RNG spring was slightly longer than the stock spring, but felt slightly easier at initial downward force but had more resistance than stock as I continued to push down. RNG would not tell me what the spring force was.
I then tested the clutch with the RNG spring and the OEM 18 gram weights with the resultant engagement RPM of about 2050 RPM, a little smoother engagement but still not good.
I am really struggling to get any answers on the best combination of spring / weights to achieve a smooth engagement of maybe 1800 RPM. Note; idle RPM is approx. 1600.
I have searched all the forums and cannot find good information, and RNG appears to be not willing to share information. What gives here? Anyone with experience to share?

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.
