Model: 2000 Adventurer (standard)
Carbs: Keihin CVK
Airbox: K&N in Trophy/Sprint filter box w/ 2x1.5" holes at bottom inlets.
No snorkels.
Pipes: Aftermarket (?) 3:1 with conical collector.
Manufacturer unknown, from 1998 Speed 3.
Muffler: DIY high flow.
Cams: Triumph 'blue' Sprint/Trophy
Ignitor: Stock 8,750 rpm
Setup T-43 (43rd setup since January 2007)
Main Jets: #130 Keihin
Needle: Factory Pro Titanium, clip on bottom notch
Float Height: 17.5mm
Pilot Jets: #38
Mixture Screws: ~ 2.5 turns
Slide port drilled to 3.0mm from stock 2.5mm
Butt Dyno Results:
Small throttle operation excellent. Smooth to 7000 rpm, no bucking or audible misfire. (#40 pilots caused misfire/weakness throughout range)
WOT -- Hot and Cold -- no misfires or bucking. (#125 mains caused misfire @ 4K rpm.)
Notes: Could feel thrust surges between 4-5 K and at approximately 6.5K indicating a lean mixture at 4K, rich mixture from 5K - 6.5K, and lean mixture over 6.5K rpm.
Thrust has substantially increased over the entire operating range and the zero to redline time in first gear has decreased substantially -- I estimate 1 to 2 seconds improvement.
A 0-60 mph test with my digital speedo read 3.5 seconds but that is unverified -- I need to check the speedo calibration with the GPS and verify the reading.
----------------------
UPDATE: The wire from the speedo sender unit came loose and dropped onto the ignition wires. That resulted in ignition pulses being added semi-randomly to the speed sensor pulses. That made my miles a lot shorter and my 0-60 time a lot less. I'll update again after I cal the speedo and verify it's accurate and consistent. Sorry 'bout that.
----------------------
UPDATE: Mileage: 10 Oct 07: I did a group ride last weekend with multiple gas stops and the mileage varied from 34 to 40 mpg (US) depending on riding conditions and speed. The multiple fuel stops were necessary due to a Sportster with a peanut tank.
----------------------
It's going to take a dyno run to see what the ultimate results of this configuration are.
