I am going to add my 2 cents since that is what forums are about
I had a similar product on my VTX 1300, that bike had a stiff clutch pull also. When I got the Vic finding a clutch pull reducer was high on my list. I found the one everybody is talking about at Victoryonly. But then I found some other posts and articles that got me thinking.
After reading the articles I felt very embarrassed since I am a electrical/mechanical engineer by day. I should have known what was happening.
Like mentioned above, you are risking premature clutch wear. It is my opinion now that it is not a Risk but a guarantee.
To put the operation in very simple terms: When you pull in on your clutch lever you pull the cable that is attached to the clutch arm, which "rotates
" to disengage the clutch. You only have a finite distance you can pull the clutch lever, which relates to a specific amount linear movement of the cable which translates to a specific amount of rotation on the clutch arm at the shaft. The way the tension reducers work is to "increase" the leverage by lengthening the arm on the clutch arm. Here is the problem, by lengthening the arm enough to get a benefit in "felt" tension reduction, you need to pull the cable further to get the same amount of rotation out of the arm at the shaft. The problem is you have no way of increasing that length of pull!!
So the result is either (A) you don't fully disengage the clutch when you pull the lever, thus the plates are still rubbing, or even worse (B) you don't let them fully engage when the lever is released. Either way will cause premature wear of the clutch plates which is a bad thing.
The clutch on my VTX was starting to slip, not major but I thought it odd after only 30K and I am not an aggressive rider
But after I found the threads and articles about these tension reducers it all made sense.
You can take what I say with a grain of salt, that's cool, you can do your own research, thats better, but if you think about what I described above it should make sense that these tension reducers are not a good thing. You are better off to exercise your hand and build strength or if you have $$ to spend, upgrade to a hydraulic clutch.
Think about it, if there was a way to reduce the tension, the engineers designing the system would have done it, or there would be a true OEM accessory for it so Ma Vic could profit.
I am not trying to rain on anybodies parade, I just want to put some information out there to help my fellow riders out there stay riding. 99% of us bought our Vics to ride, not to work on them
