I feel the need to test myself & the last of a design that has been an amazing piece
to ride.I have been thinking about taking my brand new 08 650 out for an adventure
that if completed will make the mark of the breed another feather for her cap.
I will be taking her to saltlake city from portland for the dealer show & then to Las Vegas
for the start of the vegas to reno! Then back to portland! pics coming soon!!

Wish me luck breatheren!
 
Not only would I like to know how you fare, I'm sure we'd all be interested in any special prep/modifications you've done. On a related note, do you plan to push the limits of the service intervals, at least for the non-race part of the trip?

Oh yeah...good luck! :)
 
Good luck, although I think both you and your 'Berg will come through with flying colors.
 
I have a lot of confidence in these bergs. You'll do great. By the way thanks for the radiator guards a while back, and the larger berg desert tank i'll be getting in time. Also, all the 08 bergs here in San Diego are red sticker bikes. Are all the 08's this way?

Well blake i'm leaning on the side of caution,do to the cost of the race fee & overall
cost of the trip.I think oil change's every 2 to 3 hundred going & none for the race
portion then maybe just one for the ride home,we'll see. I will post some pick's of
the progress made so far today & will continue to post the updates as completed!


Thanks for the confidence guy's :D
 
Nice job Boss.
Its one way to deal with the cost of fuel for sure.Maybe we will come full circle and the "run what ya brung" :D days will come again...
 
Best of luck Rick!!

Are you planning on running the same gearing for entire adventure?

Given the following:

engine rpm=5000
primary reduction 29/87 or 2.68:1
overdrive of 6th gear 27/20 or .74:1
secondary ratio 16/42 or 2.62:1
street tire 120/80= 4.4" side wall height. 18" wheel dia + 4.4" side wall height X 2=26.8"wheel dia. x 3.141= 84.17" circumference or wheel run out. (not sure about the tire size, took my best guess)

So,
5000 Engine rpm/primary reduction of 2.68=1865.67 rpm's of the trans main shaft.

1865 trans main shaft rpm X trans OD of 1.26 (.74:1)=2350.74 counter shaft rpm.

2350.74 counter shaft rpm / secondary ratio of 2.62=897.23 rear hub rpm.

897.23 rear hub rpm X 84.17" of rear wheel run out= 75,458.4" per min.

75,458.4":per min/12"= 6288.2' per min.

6288.2' per min X 60= 377,292 feet per hour.

377,292 feet per hour / 5,280 =71.45mph.

Applying the same formula for 8000 rpm's yields 114 mph.

Looks like that gearing should get you there plenty fast.
 
The 16/42 gearing appears to be near the same as my 15/45. Which is taller?

Pollo,

Your gearing of 15/45 is 3:1 Boss's gearing of 16/42 is 2.625:1 and is , significantly taller.

Consider this, if you increased your counter shaft sprocket to a 16 with your 45 rear the ratio would only go to 2.81:1. As a rule of thumb, 4 teeth on the rear sprocket is worth one tooth on the front. It's not exact, but, it's close.
 
Yea , I get it. I get mixed up sometimes what action that front sprocket does. So 16/48 would be the same as 15/45. Yea, he's a lot taller, and i'm tall enough! But he's doing the marathon. I always thought it was 3 teeth on the rear worth 1 on the front. Thanks
