It would be interesting to pitch a 'run in' UCE bike against a de-restricted AVL - I reckon performance should be pretty similar. Although speed isn't my top priority it might be a fun race  ;D
I had the chance to ride a run in AVL today, the UCE faster and smoother.

Was it a de-restricted avl with carb & pipe, sprocket upgrades? I've rode both & agree the uce is a great bike but didn't have a chance to push it much. I don't think there will be much difference in the top end for both bikes.

No, both bikes were stock, perhaps an AVL with all those mods would equal a UCE. It would be interesting to see.

I'm sure the AVL could be as fast as the UCE, I've riden both and the difference for me is that the UCE seems designed to cope with slightly higher speed. It feels more comfortable throughout the speed range which is what you'd expect I suppose.

I know emission legislation was behind the UCE development but you might as well make one that's a bit faster while you're at it, new technology and all that.

I've done 900 miles now and for what it's worth mine will cruise at 60/65 all day, I've seen 80 on the speedo before I felt guilty and backed off.....and it's returning 78mpg :o

I rode 300 miles on mine yesterday, 60-65mph all the way. I  filled up this morning and checked the mileage again,  I got 78mpg too, not bad at all.

If I have calculated this right, (and please correct me if I am wrong):-
If a C5 is doing 70 MPH, then a G5 will be doing 3.88 mph more. This being due to the difference in wheel sizes, (18" & 19" resp.) and all other things being equal.
Am I right or am I wrong!!

Don't think you're right, I'm pretty sure the C5 has an extra tooth on the gearbox sprocket to compensate for the smaller wheels.

You may be right --the G5 gearbox sprocket has 17 teeth.Don't know what  the C5 has though. I did say all (other) things being equal.

The G5 has a 17 tooth sprocket.
The C5 has a 18 tooth sprocket.
The 18 tooth sprocket will fit on the G5.
At least it did on mine! I'd like to go up to a 19 or a 20 but there isn't enough room for anything bigger than a 18 in there.

Can you tell much difference with the 18 compared to the 17?

There was a month and a half that I didn't ride the bike (REcall) and it had the 17 on before and the 18 after so it would be hard to give a side by side report of the performance.
The motor didn't notice it at all, it still has all the pep it had before and less vibes at the 60/65 cruising range. Gives each one of the gears a bit more "legs" than they had before. I'd recommend it to anyone that has a G5.

I'm used to the 4 speeds and big sprockets (19's & 20s) on my older Bullets.
You seem to get a lot more out of each gear on a 4 speed.
It seems to me that I'm always shifting that 5 speed. No sooner than you let the clutch out it's time to shift again.
A bud of mine has a 97 iron bike with a 5 speed and a 19 tooth sprocket and it doesn't give me that impression. Must be the larger sprocket.

I can't go up a tooth on my C5's front sprocket, but when it's time to change ther rear tire I'll try a 90 series instead of the stock 80 series. A taller tire should give me a bit higher ratio, we'll see.

I installed a set of Avon Road Riders on my G5 early on and could notice the difference in size right away. Only problem it was the wrong way for my kinda riding.

Next set of tires is going to be a 3.25 x 19 Avon Speedmaster on the front and a 4.00 x 19 Avon Safety Mileage on the rear.
The OD of the 4.00 x 19 Safety Mileage is over 1" larger than the 100/90 x 19 Road Rider that I have now.
 
I know that the Road Rider is being hailed as the greatest tire ever made but I'm just not seeing it. I have just a bit over 1,200 miles on the rear and half the tread is gone already. Looks like it's going to be a 3K mi tire.
If I had it to do all over I just would have left the stock Speedmaster/Safety Mileage combo on it. Got 10K out of em and then get the larger rear.
I got the roadriders dirt cheep and just couldn't bear to see em on my old iron's. So the stock G5 tires are on my 01 now.

Yeah I think the stock Avons won't last long on mine, showing wear already. But to their credit they handle great and ride smooth.
