Best regards,

I would have to change the front fender to use that one... HOWEVER, the 1937-38 Sport Scout had a version I can use. Now if I could just find one.... Cool

Completed break in today with 350 (+/-) mile run round trip to Zuni, NM. Only 20 unavoidable miles on I-40. Rest on route 66 and highway 53. NO problems (except when I got stupid, missed a corner and did a little moto crossing through the sagebrush. No damage to bike. Rider has sore back.) Embarrassed

Considerable wind. Headwinds, tailwinds and cross winds. Lot of tribal police and sheriffs deputies out. (Tribal police are NOT to be messed with.) Got the hairy eyeball from guy on new Indian with XX thousand dollars worth of "Indian" accessories on bike and himself.
I'll try to get the bike on a dyno fairly soon.... Cool

Taking bike out early before temps hit 90+. Engine pulls THROUGH 7,000 in 1st, 2nd and 3rd gears. 4th and 5th = ????... Beyond my comfort level.... (Way Beyond!!) Gas mileage in 55 mpg range @ 60/65mph. Far more comfortable ride with the 12" Intruder 800 shocks.

What was indicated MPH? What tire you running? Some of these guys have it all worked out.. Transmission gear ratios, RPM, tire size, Cha Ching, translates to MPH. That speedo lies like Speedos with a sock in them.

Rear Tire = 140/90-15 Michelin , Front Sprocket = 25 tooth , Numbers = 3,660 RPM = 60mph (math by Dave).
195 pound, 6 ft. rider (sitting upright, no windshield ) 5,000 RPM in 5th on level straight at 6,000 ft. above sea level. (Too busy paying attention to the road to eyeball speedo at the time... )

Numbers = 3,660 RPM = 60mph (math by Dave).

5,000 RPM in 5th= MPH?

I Used to be able to See how numbers worked sometimes,, now ain't when..

1,830= 30
915 = 15
5,000/ 915= 5+
5X 15 = 75,, meehhhh,, a hair over 80..
If you had gone to 7,000, you would've been cutting 100+.
If IT will do the 7,000 min fifth..
You're not exactly tiny.

At the dyno this afternoon.... 6,000 feet above sea level 96 degrees F, 24.77 in-Hg, 14% humidity SAE 1.25 Red line 7,000
At the BACK TIRE....

Max HP = 31.73 @ 6,300 RPM
Max Torque 32.22 @ 3,500RPM (Note: Torque curve stays 30.0 and above 2,500 rpm to 5,500rpm)

Carb is running way to rich at 4,300 rpm and above.... I'll be talking to the Lectron carb techs tomorrow to see what I can do about that.
Tweaking the carb, lower temps and more humidity should squeeze a bit more out of it, I'll definitely get better mileage..... Over all, not bad for a baseline....

It is great that the maximum torgue is at 3,500 rpm.....it is right down where you can easily access it - without having to shift to a lower gear. (That is why we love a Thumper!).

The HP number is a bit lower than I would have hoped for - however it is rear wheel HP, and you are at 6.000 feet. A normally aspirated engine is supposed to lose 3% power for every 1,000 feet of elevation - so you are down 18% from what it would make at sea level.

I don't know how much HP a motorcycle loses in getting the power from the crankshaft to the rear wheel. Most online comments for cars is around 15% for a manual transmission - but some folks claim this number is too low - but they don't use an efficient belt for the final drive.....so let's assume it is 15%.

So with a correction your 31.73 HP would become 38.7 HP at sea level, and then with the 15% correction for the drivetrain it would become 45.52 HP at the crank!

If the stock bike is around 30....that certainly is an impressive improvement!

Thank You for the input Dave, I'm happy with the results. For the number of $$$ I have invested in the Thumper, I have a fairly ideal motorcycle for my style of riding and the type of roads I ride. Cool

60 -65 mph all day long with the ability to hit 85 + for passing by just rolling on the throttle. Cool
