So what is it and what are the advantages of having it?
lets get that susp kit on TimRog is right. Again....
I beat this up on the other board about what you get out of it. The bottom line after riding is you get excellent RPM range on hill climbs, higher top speed, and no loss in torque.
If you only did the sheave alone, you would be MUCH higher on top speed. But doing the sheave alone actually will impact your climbing ability. By doing the duners kit, you will be a few MPH faster on top end, much better climbing ability, and a bit of a punch off the line.
Best all around mod I ever did. So far.
What weights and spring were in your duners kit? your top speed should be the same.I have an '07 660. A couple months ago I put on a KMS sheave, and a Dynatek CDI. Top speed went all the way to 53-55. Last week I put in the KMS duners kit. Top speed went down to 51-52. I haven't really ridden many good trails yet, so I can't tell you about hill climbing. I did notice a slight gain in low end torque.
These are probably the only mods I will do to my engine and I am glad I did them.
A very small amount. the 12/13 combo works pretty good, with my 14's I can accelerate as fast as 1fast06's bronco clutched rhino to about 48, so I believe in my suggestions. he has more top end then I do though.Rog,
Thanks for the tips. I appreciate it. I am not sure that I am ready or willing to just tear into the sheave again at the moment. I will probably put another few desert rides into it and then maybe change out the weights when I do my next inspection.
Will the 14g weights change the bottom end??
