mr steamroller is a happy man , made a new change ..26hp .12.6 footpounds of touqe . some things which i did 6 months ago failed and now know where i went wrong . could not work out why after the gp it was only 22hp so forgot about his bike and worked on mine lol

26hp an still more to come what can i say

Seen a real cool trick Jerry branch used to use on the dyno (not interia) in was in the Kevin Cameron book......
He used to have a pump on the carb breather tubes and he used to either put a vacuum on the breather or put pressure on it to see what the altered fueling did at each point of the re range it was even calibrated so he knew how much to altered it beats changing jets constantly.

He also said about the fuel not in the Dyno room away from hot engines lol

then again i guess that what a lappy and injection on the Aprilia is for

5 psi in the rear tire would not of helped with a good reading

carb breather tubes vent to atmosphere and react to atmosphere (not as much as we would like)
what he used to be is alter the atmosphere the carbs actually read.
by either a vac or pressure to richen or lean the mixture. only talking slight pressures here. like an old school air bleed on an turbo waste gate.
same reason pressure fed airbox's are vented into the air box on the ram air bikes

Nice Husa.

Very do-a-ble. In fact thinking about it Ive the perfect bits sitting under my desk.
Matched up with an oxygen sensor, one really could clean jetting up very quickly...

he allegedily had it so he could match the percentage on the jetting he looked for the torque of course at each rev interval.
But o2 sensors were not so much around at all then.

Why am I not surprised at that statement?


If it ain't smokin' - it's broken.

Strikingly similar power output i.e. 8.5k to 12k. Of course mine is the least powerful of the ESE bikes for the Nth Island series.

[mr bucketracer]

think i will have another go at a 2 stroke been 16 years but now you can use better stuff like pistons . most probley only 2-3 things more to try on the fxr but unless i go to a 4 cyclinder cut down to a 2 or a ktm motor to get more rev's i'm wasting my time but do like the low reving fxr's because they don't drop valves ...well not yet lol
