I made the mistake of not bookmarking any of the jetting sites
previously mentioned. My elevation here is about 600' above sea level.
I'm trying to decide whether I'd need to change jetting for Brushy
Mountain where the elevation appears to range between 1,300-,2500'?
And if so, how much change can be expected.

You may not have to make any changes... just depends on how well you
are jetted now for your current elevation. I'd probably just go there,
take a quick test ride and make the changes as necessary. >> Stay informed about: Jetting - Revisited |

Dang, I DID bookmark the jetting sites, and they're all gone. Linkrot,
as they say. Guess we'll have to buy Eric Gorr's book now.
I'd be willing to guess that if anything one clip up on the needle
would be all you'd need, if even that. Maybe one step leaner on the
pilot, but that's probably overkill.
I hate you

You should be OK with your normal jetting.

Check your e-mail.
Sorry, I couldn't find the easy way to strip one or two pages out
of that, but print what you like for reference.
Looks like you might want to go one size leaner on the main and
one clip leaner on the needle, but I'm not sure I'd worry about it
a huge amount. It *may* be cool enough to cancel out any
elevation differences.
Or not.

I was hoping to avoid the "HardWorkingDog" syndrome witnessed in
Idaho last year. ;-> I hate having to work on my bike when I should
be riding! And unfortunately, my entire carb must be removed (along
with the air box assembly) in order to change jets. It won't rotate
because there's not enough clearance between the carb and center case.
After hearing opinions and checking out the info Scrape sent I
think I may be fine anyway. It's jetted spot on for here, even when it
was 100-degrees on time, so mid-80s at 2,000' will probably be okay.
If the needle needs to be repositioned, I should be able to accomplish
that without removing the carb.
Thanks, Dudley!

Syndrome?
Actually, I kind of like the sound of that. It was fun changing out
the main jets on both bikes, although I did hold up the group a bit
and I do feel just a touch bad about that. It didn't take me THAT
long, did it? But then, I usually bring up the rear anyway.
I've never had to change the main jet when riding in areas from sea
level to almost 5000'. Never having ridden at 9000' before, I was
skeptical about the need to rejet that much. Not any more.

We'll see. I think I'll just leave it stock for now. Hopefully, as
you mention, the cooler air temp will offset the higher elevation.
(Assuming it *is* cooler that weekend). Thanks, Scrape!

Funny, because I *did* see Eric's new book for sell while looking
for info. Too bad I'm such a cheap bastard.

Send me your specs (pilot, main, needle#, clip#) and I'll try to run
them throught the spreadsheet and see what it says...

Hehehe. I was just teasin' ya, Charles. I was so anxious to ride
with you guys and then I lasted what, 6 or 7 minutes before my water
pump drive gear went out and took the clutch with it? Damnit Charles,
maybe if you had taken a little longer replacing those jets...
;-p
