I had the wheel on and off for tire changes and sprocket changes. I usually didn't keep the chain adjusters locked up so I had to adjust my chain tension after mounting the wheel. So the ten adjustments kind of reflect all that, not that I was adjusting the chain every 300 miles or so. When I...

OK, the whole story. When I got the bike it had 5K on it. After about 1000 miles I experimented with the gearing by getting a JT 46T alloy sprocket and a new VX chain. I did think there was some added smoothness with this change but I wasn't all that familiar with the bike yet, and with the...

well, that was nicely patronizing The JT is very precisely made - I measured less than 0.001" runout of the tooth circle to the hub circle. If this is stamped then it is either milled or broached very well. Perhaps you have some wisdom why JT would make them so very nice if it's not necessary...

As I've gotten used to my bike I started to notice an odd noise - a undulating schess-schess-schess. It seemed to come from the front of the bike and was there if I coasted with the clutch pulled in. It definitely varied with speed and seemed to be front wheel related. But not the brake it...

That is my experience, which is exactly three different 2V bikes. I first experienced it on my beloved but oh so flawed MTS1000DS Multistrada. I seem to remember the redline was 9200 or 9500. It would just be wailing away in the most satisfying manner when - the very abrupt limiter would cut in...

Well, some time and miles have gone by. So far I've not had the time or stomach to take mine in. My local dealer, Greg, I've known and basically liked for 23 years. But I have never bought a bike from him because he - does - NOT - deal. It makes for awkward conversations, and I'm sure this will...

I'm getting right at 60mpg in my usual riding that includes mountains and desert highways. I usually cruise 75 when I can. I have a tall windscreen, which took a few mph off the top speed. By comparison - I got low 50's with my Triumph Sprint RS, probably going a little faster, and about the...

Slightly OT but I just had Racetech rebuild and revalve my WR250R forks. These USD forks are noted for being harsh and these is lots of online about fixing revalving etc. So, I went through the normal RT questionnaire about experience, weight, bla bla. I said I wanted plush plush plush. They...

Pismocycleguy, what model are they for - did Knight design say these would fit?

I had a pair of Knight Industry 1.5" lower pegs left from my dearly departed Sprint RS that I adapted to the NC. These pegs used 3/8" pins, so they also needed sleeves, and a little spacer to take up some missing width. I machined flanged sleeves on my lathe. I had to art the stops in on my disc...

Waaa,,, no calculus nece. The constant came from Watt himself after measuring what a horse could lift. Dynameters measure power against RPM, from which the torque values are trivially calculated. Back to dduelin's comments about the peak power and redline - Exactly, the engine is merrily just...

Work is done by power (energy transfer). Agree that HP is the important info, and the torque plot can be inferred from the HP plot. Full throttle dyno run HP don't tell much about the bike in the real world, but the torque value kind of does. Bigjeff, all flat it seems? No doubt about it -it's...

I don't disagree with the first part of your statement. The second part I know what you mean but it doesn't bear on torque and power. For some starting speed,acceleration will be greatest when the bike is in the gear that has the engine at the maximum horsepower RPM. Here is an example of...

I'm not trusting my gas gauge at the moment, last weekend it seemed to hang up at the second to last bar. Since I was on a freeway with lots of businesses I kept going, waiting for it to drop to the last (flashing red) bar, but finally at 213 miles I got off for a fill up - 3.47 gallons! So now...

Some physics bits from Wikipedia. And pardon me, I'm not a physicist, I'm a geologist that long ago went into an optics career. BTW, there are bunches of hotrod explanations of torque and horsepower out there. "The constant 5252 is the rounded value of (33,000 ft·lbf/min)/(2π rad/rev)." *5252...
