Silly bugger

Sniper. I havent had such a good laugh for ages. Powerband indeed !

Is it suppose to be an optional extra or something.

[Blairos]

He should have asked if it was a Battery Powerband, or a Mains Powerband

[White trash]

Give the fucken kid a break. Poor bugger's probably had no experience what so ever with bikes, no one ever told him or showed him. Which is why he's selling it.

I remember when I was seven, pointing at the coil on my KT250 and telling my mates "That's the powerband right there!"

Edit: I forgot, you guys knew everything about bikes from day one.

(It is fucken funny though)

I can recall many years ago trying to sell a car to a young guy. He didn't know much about how cars worked, and asked if he could bring a mate with him who knew a thing or two. I agreed, but I think even the potential purchaser was a bit taken back by the statement his mate made.

The mate: "I think it needs a valve grind"

Me: "Could be, but I haven't noticed any loss of compression or any other indication."

The mate: "No, I really think it does need a valve grind. But maybe it doesn't need a new one, you may be able to get a good second hand one from the wreckers."

The sale didn't go ahead.

Hey I gotta get me one of those...!!!! Do you think Coleman's would stock special Suzuki ones?

[Lord Derosso]

I knew everything from day one. After all.. if I wasn't so modest I would be perfect. More to the point though... is it really possible for bikes to have more than one powerband, or was someone BS'ing me when I was learning the talk to do the walk etc etc. Perhaps some smartass could explain the how's whys and whens of powerbands. I mean obviously its to do with the gearing but I will be the first to admit that I just take it for granted once I have found the range at which each bike hits it. I just ride the bloody things, I dont get into the fiddling around especially after what happened to me some months ago because I got smart and wanted to look under the tank..

I do believe it's just when an engine in it's most efficient rev range, making the best use of the fuel/air mixture and ignition timing available to it.

It refers to the "band" of revs the bike makes the most power in.

I knew that....!!! Seriously though, this has been one of the most vexing areas of development for manufacturers - trying to broaden the powerband to make engines more efficient. The internal combustion engine is only about 30% efficient and has a relatively narrow powerband, hence the development of variable valve timing and lift with powerful computers controlling things. IMagine the performance if they could get over 50% efficiency!

Yes, perfectly possible to have several "powerbands" on a bike.Though normally we call the gap between them a flat spot. The old OHC singles often had one powerband (though they weren't called that then) as it came "on the cam", and then another , more powerful one, as it came "on mega". It's nothing to do with gearing, it is to do with engine revs. Some engines have very steep power curves. The area outside the steep part produces little power, the area within the steep part, lots. Hence, in the powerband. The practical effect is that you start off trying to accelerate, nothing much happens, you twist the twistgrip right round, the bike accelerates slowly, sluggishly, you think, "What a dog".The all of a sudden it reaches X rpm, and the front comes up like a striking snake (not a Cobra though, they would never be so illmannered) and clobbers you on the back of the head. Then, if it's a Kockasucky, and it succeeds in tipping you off, it will come back down and dance a victory dance on your mutilated body. Vicious brutes.

I nearly had a fit. I could hardly understand a single word those "homies" were saying

Post edited, thanks Ixion

[Ixion]

Honies ??? I think you mean homies, bro.

Sigh. The homie selling it admits he has no bike licence. The homie thinking of buying also has none. Obviously neither of them have a mechanical clue. Poor, poor, poor li'l two smoker. Petal and Phoebe are sobbing over it right now. And they consider Whangarei to be 8 or 9 hours from Taupo! Darwin is the only one going to come out ahead on this.

[Crasherfromwayback]

I like it.

I have a sad story to tell about the later high powered 250 2 stokes.. my mate (13 years riding, he is 19 heheh) had two of his mates die within 2 months of eachother (after owning 2 stokes for 2 and 3 months respectivly) after getting them as first bikes. One hit a pole the other I cannot remember how he died. But yeah, this might be another tale like that if they are stupid enough.

Blah blah 2 strokes are bad.. no, mabey a bit more tricky (later 250 2's) and not the best 1st bike but you just need to have common sense. 250 IL4's are enough to get you in the shit, same with any other bike really.... Just take heed if you are thinking of doing the same thing.

You're all a bunch of giggly schoolgirls laughing at the dork across the hallway... But it is pretty funnay!! Hahah!!

Jonathan2003's much too honest! Let's toss another spanner in the works... Haha!!
