That tyre ... Single side swing arm mod/engineering challenge ... 

It's been done...

Jim's Bikes are so sweet

Doh! ... that explains why I had a foggy image of that in my head!

My memory chips are mere salty crumbs at the bottom of the bag recently! Lol

I've got the Delkevic aftermarket pipes and exhausts, so my bike is a bit more noisy than stock.

Generally, I cruise around at 3.5K~3.7K in 5th, and shift around 4K. If I'm feeling naughty, I'll rev it right out to 5K before shifting.

The only time I really get over 4K is if I'm going over 80Km/h. 6th gear is strictly for 70Km/h plus for me.

  you must get fantastic gas mileage!!!!!

500Km per tank. Not bad for about $25.

Beware of engine lugging at those low revs in gears, revving is healthy for a GS engine but lugging can be deadly.

What's the damage?

Ok, after reading this thread, I feel like I am guilty of repeatedly kicking the family pet.  What follows is personal experience/opinion, not science or fact.  Mileage may vary... all puns intended.

Apparently I am a maniac.  I ride my two GSs like I stole them.  My daily driver (26K mi) I redline in 1st, 2nd and 3rd when entering the interstate and my "touring" bike (16k mi) routinely sees 9k+ RPMs.   When a buddy (KTM 450) of mine and I ride to lunch, I hit redline a half a dozen times just for a more fun ride there and back.  Oh and I VERY occasionally miss a shift and "zing" the motor... oops.  A normal shift for me is 7-8k RPM and I try to keep "cruising" RPMs between 5-6k with 70 MPH being 6k RPM.  I have also ridden it from fillup-to-fillup at 70-75 mph non stop.   

So, besides going through chains at around 15k miles and tires around 11k miles (including wearing off some of the nipples), I don't leak and haven't shot any parts out the exhaust.  I just wanted to add my 2 cents worth in that these bikes aren't dainty little teacups.  Who knows, maybe I will be dropping a couple of grand on a motor rebuild in a few years but no problems so far.  I just figured that's the way these bikes were meant to be ridden!   

It wouldn't be so bad for the engine as much as the mounting bolts, but that just fits in with the whole maintenance schedule.

After evaluating my riding style, it seems that I might have been lugging a bit riding up certain hilly sections, so I'll just shift down a gear for the hills. But generally the bike seems to be smooth most of the time I ride. You just need to learn to get the bike to sing using so little power. I did try revving it out today and the power really does pick up around the 5K mark.

Lugging is heavy on the engine,  from what I understand both conrod bearings and the crank bearings take a beating. Obviously once will not break anything but once a day will.

(A bit late but...) I totally forgot about that bike of Jim's!!! Indeed it has been done 

I geared my bike with a +1t front, and a 35t rear.
The bike does do 3k RPM at about 40MPH, but not lower (that would be lugging it), and goes all the way to 6k rpm at about 80MPH.
I would probably been better off with a 36t rear, same as the other guy on ecomodding, who says the 35t is a tad too heavy.

I'm riding it carefully, and mainly on the interstates.
If I want to go 85+MPH, I downshift to fifth, which takes me to 100MPH easily (on the dash speedo), and then creeps up to 120MPH when ducked forward).

A 36t should give better top speed in 5th.

In 4th gear, my bike is geared like a 250cc, 1k rpm per every 10mph, meaning at about 100MPH in 4th (10k RPM), I'd really want to shift to 5th.

So far taking it well, but I'm selling the baby.
The gas mileage isn't too good (around 55MPG, but I usually do highway with it), and I find myself taking it less and less on the road (just to keep the battery active).

I went to a 17T CSS, on a ride from Seatac Wa to Packwood Wa I managed to get 69.8 Mpg, even with one step larger pilots and mains on an otherwise bone stock bike. For what I do that was perfect.
