OK, at the start of this season we picked up a rebuilt Vortex black 2 disc clutch to run on my sons kart in Jr. 1 restricted class. I have no complaints about how the clutch worked. After the first night using it, I followed the instructions I downloaded for servicing the vortex clutch, but I could not get the screws out to disassemble it! I broke 2 wrenches trying to turn the screws, so I gave up before I wrecked the screws and for this season I have cleaned the clutch with brake cleaner. I have tried a few other times to take it apart, but no luck.
About the third race of the season I was cleaning it I noticed the drive hub is cracked where the keyway would be on the crank shaft. We had no choice but to keep running with it. It doesn't seem to be causing a problem.
The past 3 weeks there are a couple of new drivers at the track that are very rough drivers! A couple of times my son got tangled in a wreck with them, and his kart stalls and dies. I am starting to wonder if maybe the clutch is not dis-engaging as fast as it should, and when he gets stopped quick it is killing the engine.
So, now I am in the market for a different clutch. If I can I am going to replace it for the rest of the season and send this one off to be rebuilt during the winter so I have a spare in case I need one. Also, if my daughter heals up from her latest injury I will have a better clutch for her kart. This leads me to a question.
What is the difference between the Bully 2 disk clutches and the Black vortex 2 disk clutches? We have used a Bully single disk clutch and really liked it, and we used the vortex black and really liked it too. Are there any real big advantages to one over the other?
