Doesn't cycle like it's supposed to.
Doesn't fit tight.
On Christmas I was excited to see that I got the RAP4 cyclone upgrade kit because this was all I needed to fully upgrade my A-5. I installed it that night using thier video. Its real easy to install but the video was terrible. After trying to put it into the cyclone compartment I noticed that the ratchet pin did not stand straight up, it was at a slight angle. I figured it just need to be broken in and that it would straighten out later. The next day I played a small game, as I started to fire I realized nothing came out half the time. The sad thing is that I was using semi-auto and not full-auto. I looked in the cyclone and saw that it wasn't cycling at all. I pushed the pin manually and it cycled fine. I wasn't satisfied so I took it apart and looked at the cyclone and everything looked fine. I thought that maybe the spring guide in the vortex put to much pressure on the ratchet so I snipped off one ring and put the cyclone back together after oiling it. I then tested it on full-auto and the first 8 shots were fine but after that it quit cycling. Needless to say I sent RAP4 an email and tried calling them but without any luck. I began to ask around and found that alot of people have had problems with RAP4's cyclone upgrade and some of their aluminum powertubes. I guess thats what happens when their made in China.
Don't buy this cyclone kit, it's not worth the money or trouble. Buy the Tech T upgrade kit because it works and they back up their products, unlike RAP4. Tech T is also made in America, so you know it's good.

Are you sure your trigger pin and spring were installed properly, and that your rachet pin was also installed properly? I have not had any of the problems you experienced, so I think you might have gone wrong on the installation.
It does sound like a ratchet problem. Check and make sure your paddles are all the way seated to the bottom. I had the same problem and I found that the paddles weren't properly seated and it caused the ratchet to be off center
I took it apart multiple times and it did the same thing evrytime. everything was installed properly and it would work for the first 5 minutes and then it would stop cycling unless i manually did it, I talked with another person who had the same cyclone upgrade and they said they had the same problems and that they blamed it on quality since its made in china. I bought the techt version and never had any problems at all. Ive sold it since then and now have a sp-1 with ups. funny thing is i posted this last year and i was just now notified of these posts. no worrys either, everyones entitled to their 2 cents, otherwise i would never have posted
