HI boys
I have no Downtown yet (I have a Grand Dink 125), but I bought Pulley rollers and sliders one month ago...
My experience, the rev is little higher, because of that the acceleration is much better, there is no "hole" between 40-60. I haven't noticed the consumption would changed at all. Now it 3,5 l/100km (I am from Hungary, so I dont know that miles/gallon number, sorry), and I am a 97 kg rider. So I am totally satisfied. If I will have my Downtown (I hope), the first will be the roller changing...
I admit a secret for you.
First I put the rollers in a wrong position. The result was scary. There was a part in the rev, where the engine has less power. But in the red field the engine gone crazy, it is pulled like a bigger bike. And I can reach the max rev (10200) in WOT, it wasn't stop at 8200. I don't know why is that? It was an interesting experience
So this is a tuning option for crazy riders
I have tried get an explanation from Dr. Pulley, but they had no idea neither...
