Well just got my bike back from my local shop after having a Nichols Flywheel Nicholdmfg.com installed.

I think I am in love

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 so 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.

Every time I see one of these posts I get just a little closer to doing this myself.
I figured the universe was telling me I needed to buy a flywheel.

I had been reading about them before I bought my bike and one day I was going back and reading Nichols site. Then I went over to ebay and just out of amusement searched for nichols flywheel and one item came up. It had 10 min left was the exact version that fit my bike, was "brand new" and was stupid cheep :eek:.

Ended up getting the flywheel in the mail, still had the original packaging. Guy bought it then sold his bike and did not bother to set a reserve.
I picked the flywheel up and got it installed for 25 more than the retail price of the flywheel.

Ebay is a wonderful thing. >:D

Minus the clutch shudder these were my exact observations after I installed my Nichols flywheel. I'm also running a complete lightweight clutch set up (aluminum basket, plate & discs).

It bothers me that the lightweight rim option is still out there, especially since I have the small diameter axles and wheels are next to impossible to find. I don't really want to go through all the BS to make the newer style wheels fit. I'v had enough agony for one year.

You should have more engine braking when you close the throttle than you did with the stock flywheel. I know I did. The engine slows a lot quicker without all that momentum. Now if you downshift, the engine will rev more quickly to match the road speed, but this is not a lack of engine braking.

As for the light wheels. They are worth every penny. I have a Nichols flywheel & clutch basket, a barnett clutch pack, and BST wheels. These are some of the best mods you can make.

On my old s4r I ran a Nichols flywheel, a Yoyodyne slipper clutch, down one tooth on the front and up two teeth on the rear, and light wt. 520 chain and light wt. rear sprocket carrier and sprocket. I did it all at the same time, so I really don't know how much differance each mod made, but it accelerated like a cannon shot. Much quicker and fun to ride. Total off the rotating mass something like 7 lbs. or so with some of that being unsprung rear wheel weight.

Yea How ever much I want and think I will really appreciate the lighter wheels...

I think that I would rather spend the money on a new project that have been looking forward too for a long time.
Been thinking about buying a VW Ghia and fixing it up (yet another sink hole for $$$) as a fun cheep sports car for when I don't want to ride the duc on account of the weather or my friends want to go play on 4 wheels.

Ghia or wheels. Kind of funny when you think about the fact the the Mag wheels cost as much as a used car.

you know, i've had ideas about old ghias...

throw a 911 engine in that, redo the suspension, raise the center console and throw in a short-throw shifter...

edit: uh, not to threadjack or anything...

No worries I love thread jacking specially my own [cheeky]

I would really like to put a type 4 motor into the car and keep with the air cooled heritage (it's a porsche 912 engine). If I were to transplant a watercooled bastard motor into the thing it would probably be a inline 4 like a hayabusa motor since it would fit... Then I would always add 200 more hp if I wanted to turbo the thing. I think a aircooled 2L engine will work just fine in a 1700lb car.

Nope, It just removes rotating mass from your bike. Just like a light set of wheels.
It may reduce rotating mass in the engine, but not even close to what a set of lightweight wheels will do.
