Orem is on the west side of a mountain range just south of Salt Lake City. If you drive west its faily level for a bit and usually clear sailing, East is a mountain pass. I worked there one fall. 30 degrees C in Orem and I decided to explore the mountains one Saturday. Got stuck on a park road in a snow flurry still wearing short pants. Didn't drive east of Orem the rest of my visit.

To start with the gen 1 bikes had different sprocket sizes. Most riders change to the 17/42 for lower open road RPM. I agree that city riding (mpg) will not be effected by gearing.

Your V&H header will make the bike use more fuel due to the design of the header and the open can is no help for MPG. The V&H is a performance pipe. To make power you need to uses fuel.

160 miles on a tank is normal for a bike w/o mods. I get about 180 with mixed riding before going to reserve. I get 50 mpg over the road but have gotten as low as 32 mpg on spirited runs. Sounds like yours is OK.

Shifting at say around 4,500 to 5,500 rpm will gain you better mileage but the pipe is designed to run with a good solid twist of the right hand.

Correct Genius almost identical but not quite ! , obviously not listening when we were in TN - it's
what I ran there and errrr we talked about it then too lol

It's only marginally taller and corrects the speedo but it's way smoother
than stock because of the bigger cog up front way less clunky

I get about 170 before reserve

Riding Hard 135-140

I would stay at stock gearing. I like a few teeth up in the rear, but it's just a personal preference. I generally get about 36mpg avg and rip on her too much.
Huh?
+1/+2 is almost identical to the stock 17/42 gearing.

Whatever, clown. I just looked it up.. it's 1% lower in rpms. Not even noticeable.
Sure as hell not worth dremeling chit off the front and using a longer chain.



And on clunkyness...... yeah right. That's just your silver turd of a bike.

Pointless as **** on a bull. hahaha!
