no clue what so ever

Ok so I have a keeway txm 125 and it does the job it gets me to wherever I need without fail.

But I have noticed for a while now that one day it will happily hit 67mph and want to do more but it's restricted.

But some days it decides it wants to be really sluggish and top out at about 58 so uphill on a roads can go down to a ridiculous 45 mph.

It seems to be completely random days that it does it.

It will do it maybe once a week sometimes twice but I was wondering what on earth it could be? Just temperamental chinese junk or just a genuine fault?

Thanks all

Can't say I've noticed a difference with the temp and a couple of weeks ago I was riding around the highlands...


Biggest factor is wind... Even when you don't notice it. The bike does.

It really does want to go a little more when it wants to but it has a rev limiter it says in the manual..

It just bugs me as I find it quite dangerous going down the a12 any kind of incline in the road slows it right down!

But yet on a good day it can maintain its top speed up the hills...

I have the keeway superlight 125 and that does the same. I thought it was just down to it only having 130 miles on the clock.

Not sure if it's the same engine? Single cylinder carbed?

I have read that the first thing you do with a keeway is change the plug if it's the original.

it's a 125....take your helmet off when you find it's struggling and you'll notice your hair flaps about quite a lot more because of the head wind. When it's nice and speedy that's the tail wind helping you.

When it's running sluggish try dropping down a gear or two, to give it a boost.

 


:popcorn: yes ... interesting concept on a 125 ..

hopefully OP will let us know how he gets on with that one :lol:

 

I sometimes drop down a gear or two when going uphill, and I have got a 1000cc bike!! So why not do it on a 125?


Edit. In fact I can't think of one mode of transport where the need to drop down a gear isn't required at times

Are you still having this problem Robert? I couldn't understand why the engine would perform so drastically different in the same conditions. So I tried a new, better sparkplug and use shell premium fuel and it seems to have done the trick.

From max revs (limited - see OPs comment) in 4th - drop down two gears and.......


Pick yourself up. Pick the bike up and check for damage. Replace rear tyre, chain, sprockets and trousers!

My little Honda does similar. But it is definitely related to weather conditions with mine. On warm, dry, still days it is perfectly happy doing 65-70mph. On cold, damp/humid or wind days it can struggle to get to 60mph. Wind is the biggest thing, then dampness/humidity. On cold dry days it can be ok, once it's warmed up completely.


Also worth checking if you have water/liquid in your crankcase/airbox breather tube.

Thanks for the tip on the breather tube, will check that out.


This is something that happens in the same kind of conditions. Very odd but seems to have gone away mostly.

Dare I say it, but it could be due to it's country of origin! Now I know you're all big fans of Chinese bikes but this maybe a draw back. :lol:

Have to say, apart from that, it's a very well built bike. Looks like in the last 10 years, China and Hungry have got the QC better on Keeyways. Helps buying them from a good delear too though.

It depends on the gradient of the hill. Picture this, you are going up a hill in bottom gear (4th, 5th, 6th. Whatever) and the revs start dropping along with your top speed. Drop down a gear and as if by magic the revs start to rise again and so does your speed, this carries on untill you either reach the summit or run out of gears in which case you come to a stop. Simples!!
