Top speed on the straight flat...80km Bahahahahahahaha!

80kph thats sad. Put the poor thing in for a service / tune.

Or put the poor thing out of its misery

pipe from each exhaust valve

So you can use it as a wheelbarrow at the weekends

... you got 80kmh? so where did you find a 10km down hill straight with a tail wind?

[avgas]

needs oil change - clutch too slippy.
my zxr400 did the same many moons ago....same speed even

I have heard that smoking dope and drinking a couple of beers before riding is the cheapest performance improvement....it make riding a GN at 80kph feel like riding a GP bike around Philip island

Also check that you're not low on indicator fluid.

Is that a block of hash in your avatar?

pipe from each exhaust valve

Yep. When I was selling my old NZ250 (one cylinder, two exhaust ports in the head) on TM some guy tried telling me it was a two-cylinder bike. I bet him the bike (i.e. bid the reserve price. Then, if he was right he could have it free, if he was wrong he had to pay), and he went away.

(Geez, I counted the spark plug. One. And had the factory service manual with pictures of the engine in bits. His argument (apart from two connections of exhaust to the head), "no way, that's too fast for single!".)

At 80kmh roughly what revs were you at? Shouldnt be any more than say 5000 in 5th. If so then your clutch is slipping.
But go through the basics,

-Make sure your choke is off
-Clean airfilter -> replace if you need to
-Replace spark plug, don't even bother checking it
-Clean fuel filter element (it's in the tank)
-Clean carb

In that order.

oz for oz its propbably the same value today.....unless you live over here where it grows wild.

But then why does it have 2 exhaust pipes?

One pipe for each exhaust valve, the engine is a single cylinder with a 4 valve head, 2 inlet valves and 2 exhaust valves.

Nah he wouldn't be able to type if he didn't have a pulse.


....unless he is a vampire.
