Well just got my bike back from my local shop after having a Nichols Flywheel
installed. Oh boy Oh boy my bike is sooo much fun to ride now. Everything is better in my opinion.
The bike just falls into turns and goes like it is on rails.
It builds rpm's that much faster.
The throttle response is just that much more responsive / crisp.
There are always drawbacks with any change.
I have noticed that if you are not taking your time and paying attention to your clutch work, the bike will shudder.
I also noticed about a 15% decrease in engine breaking. I personally do not consider this a bad thing. You can let the clutch out that much faster after downshifting without worrying about the rear wheel hopping. But thought i should mention it since it did change.
Overall I am very satisfied with the new flywheel. Rotating mass is the enemy and I took my first step at it's reduction.
The real negative thing to come from this mod is getting me to thinking how much better lightweight rims would be.
On a side note...
The mechanic said that my front tire is starting to "dovetail" when he showed me it was pretty obvious. I'll take a photo tomorrow to illustrate what he was talking about. Funny thing is the bike only has 3600 miles on it. The mechanic said it could be due to the original rider running the front tire below the recommended psi.
