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

[Madzen]

Angie, my GN250s top speed on the straight flat is 80km, I think she may need a tune up being 26years olds, I know Im only suspose to go 70km/hr on my learners but I actually feel a little unsafe going that slow. and it seem so pointless lane spitting to the front of the que and then having then all pass me by. LOL

[The Baron]

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

I would have thought top speed would be around 120-130.

Agree completely with the above post.

Unless you're doing it all wrong and changing gears too early.

Ask the mechanic to check if you have a dead spark plug. It might just be running on one cylinder.

lay off the pies.....

This post is funny. The GN250 is a single cylinder bike. :clap:

Spoilsport I was hoping he'd say that to the mechanic. :innocent:

Or not at all...:blink:

[varminter]

I remember doing 100kph for the first time on my GN, had to look down to be sure my wheels were still on the road. Wonder what it would feel like going back to one.

[Sable]

I've been on faster mopeds.

[Flip]

When was the last time the air cleaner was washed or replaced?

But then why does it have 2 exhaust pipes?

So you can use it as a wheelbarrow at the weekends

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

[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

[breakaway]

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

Is that a block of hash in your avatar?

[pzkpfw]

pipe from each exhaust valve :yes:

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!".)

[BASS-TREBLE]

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.

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.

Was it me?

[racefactory]

I got 120 on a GN250 with a small windshield. I'm 75kg. That bike sounds a bit poorly.

[Cayman911]

I'll tell you how to cure your problem.

put that bike down. put it out of its misery of having to be a GN. forget about it.

[Bren]

Dont mock the poor old GNs, they are a solid reliable learner bike...

Just look at the amount of old GNs for sale on Trademe

You'll never get top speed on a level road ... :no:

You've got to go downhill to get that ... :innocent:
