I had one on my 74 R90 for years. I thought I would be better off without it and sold it. I wish I had it back. The new ones are $$$$. I may break down and buy another... some day. Run a flyscreen on my Bonnie.

I've had mine on for over 12000 miles, and I wouldn't be without it. I find I can ride for 3 times as long and feel less tired than on a much shorter ride without it. Crosswinds, passing trucks, etc. have little or no effect on the forces on the handlebars, IMHO. At speeds over 100 mph, it feels like sitting at my kitchen table. :-D I don't know of the effect on mpg...I did a lot of changes at nearly the same time...however, I have averaged over 50 mpg for the last 12000 miles, and I do not ride slow. I have a 790 with NARK, NH Togas, and a modified stock igniter with an 8100 rpm rev limiter...I spool it up through the gears at least once per ride. I'm 5'8"--don't know my sitting height--and I bought the 16" windshield after doing a lot of measuring with info from Parabellum...they recommended an 18" windshield. The bug line starts just above my helmet visor--about perfect for me, IMHO. I also ordered a 10" windshield for July and August temps above 100 degrees. :-D

Thanks, that is a beautiful bike. The black exhaust is a nice touch. Think I will buy the Parabellem Scout Fairing - sure is expensive! How do you like your King Queen seat? I have read that the buttons come off. I am new to Triumph - What is a NARK? Marc

The buttons are very easy to re-set if one ever did pop off.A small crochet hook and some "fire-wire" beading string will keep them in place just fine. Not an excuse to avoid the seat at all.

Thanks, Steve, I'll try to remember that--at least I can remember that you are the seat guru and I will ask you when and if I have a seat problem. I currently have over 20000 miles on the K/Q seat with no problems.
NARK = Newbonneville Airbox Removal Kit. This is simply one of the kits available to remove the airbox and use individual K&N cone filters (or some other brand cone filters) or the UNI pod filter. Some have chosen to "cut up" the airbox rather than replace it. They cut out enough to allow space to install the individual filters, but leave enough to provide the battery box and rear fender extension. This modification coupled with installation of much freer flowing silencers AND proper jetting changes will give significant horsepower increases--especially on the 790cc engines. It is not unusual to get from 65 to near 70 RWHP on the 790 with these two modifications. These are also popular modifications for the 865cc motors; however, I cannot speak from experience on the 865. :-D

Thank you for your response. Did this modification give you an increase in fuel mileage? Right now I have all the power I need. However; I would really like to get better mileage and more range from a tank of gas. I am currently getting 42-45 mpg and am not that aggressive of a rider.

What about this one...
He's a regular at the shop I hang out at...The thing is a work of art! Each piece hand made...He plans on running it at Bike Week at Bonneville this year...
You really have to be up close and personal to really appreciate the work.

IMHO, the two biggest factors in the mpg race are: 1. The number of miles on bonnie--she must be broke in for one to realize the best possible mpg...at least over 2500 miles, IMHO. 2. The rider weight (and pillion) have a great affect on mpg in my experience.
For some of us, the single, most effective modification would be to ourselves (losing a significant part of our over-weight self).
Your mpg doesn't sound out-of-line with what others post--especially if you have less than 2500 miles on bonnie and weigh more than 200 lbs.
I can't say what increased my mpg from around 45 mpg to over 50 mpg--I did mods and installed the Parabellum and went over 2500 miles in a very close time-frame. The increase could have been from the bike just breaking in. :-D Some have said they get worse mpg, some about the same, and a few better mpg after removing or modifying the airbox. One big factor that I didn't list above is throttle twist. After airbox removal and louder pipes, some of us twist the throttle more and more often. :-D
