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'm trying to help a buddy out with his bike (he's not really on the internet or familiar with these forums) and I'll admit that I am not super familiar with the transmission and clutches in these bikes. I owned a Brute a few years ago, but never had an issue like this that I had to troubleshoot.
So basically my buddy bought a group lot of 650's to build one good bike out of. He got it all put together and has it running but when he pushes on the throttle the clutch doesn't engage till the RPM's are quite high and even when its moving it doesn't really speed up, almost seems like its in "limp mode". He's tried 2 different transmissions so I don't think that's the problem.
Is there any adjustment on the clutch engagement? Anything else I can tell him to look at? Let me know if you need anymore information if you think you can help.

Just bought the atv, sounds like there’s sand in a bearing near the clutch! Any ideas?

Is there any way to mod an Outlaw 50 to increase the speed? The size is perfect just would like a little more top end speed. Thanks
