I have recently purchased a 2008 Keeway Cruiser to get my learners licence on.Question is, I am unable to get it faster than 80ks! Specs for top speed are around 115ks.
Its a V-twin and has only done just over 2000ks. A couple of people have told me that it maybe governed!
Thanks in advanced.

If its a 250cc bike theres something pretty badly wrong if it struggles to do moren 80. I'd be checking for mechanical issues such as closed up valves or timing out before restrictions

Thanks kazbanz.
I was wandering about the valves also,in the manual it says at 1000ks to inspect the valve opening. The lady i brought it off didnt have bike for long either as she just had it to get learners on also. Apart from this problem she runs sweet as. So possibly this has not been looked at. Any ideas on how i can check this! Cheers.

Check that you are using all the gears in the box

I did not check your profile lol Possible air-filter restriction
I promise not to mention anything about carrying capacity ok

Carrying capacity is 73kgs lol. I did look at air filter today, gave it a clean. no change. (it was pretty clean anyway) As for any restriction.! have just read that maybe take air filter out an see if any better!

To reduce power, sometimes there is a 'washer' in the intake tract. This would usually be on the engine side of the carburettor. Any mechanic could check it for you, or look with a torch and small mirror into the back of the carburettor. Usually they reduce the size from about an inch, down to half that. Some learner bikes are supposed to be limited in power-to-weight ratio.

My honest advice would be to book it into a bike shop and have it serviced. Just use Yamaha XV250 settings for exhaust and inlet valve settings. The people there will also know if the bikes restricted or just in need of a service. But given the last owner probably diddn't do the 1000k service I bet it will improve a heap. That said at 2000km a lil air cooled bike is likely still running in so it might improve over time

Thanks guys :-)
After reading this, Mr is making me book her in to get this sorted :-) Will let you know the outcome.

I has been a while since I was on a 250, I was on motorway doing the 100 klm and the piston melted, It was not to bad the bike came to a gradual halt
5 minutes from home

Back in the '70's I used to ride my Honda 250 Motorsport trail bike from Wellington to Napier regularly, cruising at 60 - 65mph.No worries at all.The Hyosung ought to be able to do that easily.
As others have said, it's quite fitted with a restrictorin the inlet or more likely, exhaust.

Nasty, would of been bummer if you were further away from home.

Correct fuel being used! Just a thought

I was told it has been running on Premium Unleaded, so this is what i have been using. The whole what petrol to use is confusing for me.!

Fryan melted pistons at 100km/h would be an issue with THAT bike. hardly a common issue

It's just a copy of a Yamaha XV250 Virago. They never got restricted as they never made enough power to need to be restricted. First things first, are you turning the choke off!
Otherwise I'd be doing as Kaz said, valve clearances (if they haven't been done yet, it'll need them as it's being run in)
Does the engine pull cleanly to redline in other gears! If the clearances are within spec, I'd pull the plugs and check them Clean/inspect carbs Replace fuel filter Sync carbs Check for exhaust blockages Check it's getting healthy spark Check leads and plug caps Etc

It was a CL 250 honda of course, bit of weird beast, i went through a few of them

No one has touched on your post I would be just using standard Unleaded,it is hardly performance bike, talk to guys when you get it looked at

Sep 26, 7:22pm
Yea might try this, can i mixed the petrol! or best to use up whats in there first!
kazbanz,

Hmm-but thats just a cb250 T or N with a custom tank. I wouldn't a thunk one of them would melt a piston at 100--unless the rings were worn and it was running 4 heat ranges too hot a plug.

Great news.was a little bit of crap in the fuel that managed to go through with a good thrashing by a friend of mine :-)
Running sweet now.Yay :-) Thanks guys for you thoughts and help.

Just needed an old school tune-up, stick it in 2nd gear and give it heaps. I like stories with happy endings.
woodstockblu,

Yep just needed old skool lol. im likeing happy ending also :-) I feel a lot more confident and comfortable now im a learner rider being able to do 100ks on main rd. Glad new rules for learners came in yesterday, 70ks is just a hazard.
