Guys I hate inflicting on you indecision threads like this so lets make it quick:

All things being equal, if I want easier/2nd gear wheelies and finer throttle control in and out of a turn, which is the most bang for the buck?

TIA

The flywheel's about $290, and the FCR's are about $740, so it's kinda apples & oranges due to the price.

For me, there's lots of stuff I'll buy before I get a light flywheel.
In fact, a light flywheel will likely never make it onto my bike.
But that's just me....

For you, I think the improved running with the FCR's would be a lot more satisfying than the light flywheel. From what I've heard, the FCR's will make the bike easier to ride. Don't recall anybody saying that about the light flywheel.

Since you put it as "bang for the buck", I'd lean towards the flywheel. I've got both on the same bike as you (which makes me want to agree with the last poster), and I'd say that the flywheel puts the throttle control back into your hand (both rolling on and off throttle), while the FCRs give you more punch when you hit the throttle.

BTW, the light flywheel does make the bike easier to ride. I've heard the Nichols flywheel described as the "poor man's slipper clutch", and it does have that effect. While the light flywheel makes the bike's compression have more effect at slowing the bike when rolling off the throttle, it also lets the bike's engine spin up faster when you knock down a gear and your rpm is too low for your wheel speed.

If you want better wheelies on top of that, add a couple of teeth to the rear sprocket. The effect that I found with the FCRs was that I could take those two teeth back off the rear sprocket, still have better bottom end than the stock gear ratio and get the top end back that I lost with the larger sprocket.

Hey Filmore, Did you find yourself using the brakes more often in the twisties?

IIRC, you had 43 teeth on the rear? That's 4 up from stock 39, that is "two upgrades", and now you're back at 41. I have a 14 front. If I understand you correctly this will suffice.

Actually, stock on a US `00 M750 is supposed to be 41 teeth, but I wouldn't be suprised if some of them came with 39s. I had a 43 and went back to a 41, but when I did that I was also upgrading to magnesium wheels. So, now I've gone back to stock gear ratio and the bike still accerates better than ever, so I could probably even drop another tooth or two for some top speed, but I'm pretty happy with the ride right now.

Stock gear ratio (15/41) is about 2.73:1
15/39 would be about 2.6:1
15/43 is about 2.87:1
and 14/41 is about 2.93:1

I think you're saying that you're running a 14/39 which is about 2.79:1 so you're running somewhere between what stock for a 750 is supposed to be and my old 15/43 combo.

With stock carbs and flywheel, the 15/43 combo created a really nice low end, but with either the carbs or the flywheel it might be on the verge of too low and with both I was just wasting top end, which you don't really want to do with a 750 either.

I've done the FCRs, and rode a stocker that a Nichols FW had just been installed in. Personally, I pick the FCR's. The lightened flywheel is alright, but with the stock carbs the engine braking and throttle control are just not smooth enough for me now that I know what the bike rides like with the 41mm carbs.

The kit that Chris sells comes with a new throttle and cables as well. Well worth the price I think. I've got a whole new bike now. What I thought was a great ride before is now just plain gorgeous. I'm smiling just thinking about it..

Oh, and wheelies? No sweat. Pulled the front wheel up in 3rd getting onto the freeway. Scared the hell outta the cager who cut me off on the on-ramp....

BTW, I'm not saying that the FCRs aren't everything they're touted to be... They are and then some.

I was just pointing out that the Nichols flywheel on a `00 M750 gives a lot of benefits for $200 and while the FCRs are a great mod, I couldn't claim that there was almost 4x as much benefit as the $740 price would suggest.

Hell, if we were just talking about the best mod, I'd say skip them both and get a set of light wheels. ;D

Very true Rev! If I had a couple grand laying around, some nice lightweight wheels would be finding a new home on my monster...
