Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

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?
