2006 Jinlun jl 125cc Y running help.

Hi everyone. I thought id try getting some help here as all i seem to get on Facebook is the usual "it a shit Chinese bike" or "why not buy a better bike" comment.

I bought this bike effectively for £50 as i had an old mtb laying around and sold that for 200 which went towards the 250 for this! Lol. The guy claimed it was ready for mot which i knew wouldn't be the case as its £250 lol.

So the problem i have is, it runs and rides, gears change etc. But it runs lumpy, struggles to tick over and if i rev it the revs will randomly rise and stick and won't drop. I then have to hit the kill switch or it starts smoking. Could this just be the carb need balancing? I took the carb apart, cleaned it out and put it all bk together, new fuel also. The spark plug is very sooty too. I've played with the screw on the side for the air mix but can't seem to find the screw for the fuel. Any advice would be massively appreciated. Thanks.

Spend more money next time?

For 50 UK money that's 10 packs of fags?
Sit back and ask yourself how much money do I need to spend to get a bike that runs like a new $15.000 BMW bike?

Ride Safe

I guess you have a air leakeage. In Poland we say false air.

And if you will keep the jinlun for longer time buy this:

The Jinluns are not so bad, as you think.
A friend of mine made 100 000km with a JL250. Of course after 80 000km he changed all bearings inside.

Any pic ?

Most Jinlun we talk about are powered by a twin (similar to CB125T/ CA250) machine.

I will vouch for Jinlun, I had a 250, used as a daily 80 mile round trip commute. Loved that bike

That's good to hear. It's just a cheap commuter till I can sort my Direct access out. Even if i keep it a year it will have paid for itself.

Thanks for your help guys. It's booked in for mot tomorrow morning at 10am. Have to see how it goes.

Just an update. Failed mot on a front fork seal, an engine mount needs welding, and the lights were not functioning correctly as i found out the wiring was wrong from the guy i bought it from putting it bk together shit lol. And the horn decided not to work. It had an advisory for a missing lower engine mount bolt too! So i have a guy doing the welding, for seals and giving the carb a tune and fitting an engine mount bolt for under £100. Considering the bike only cost me £50, £13 for a choke cable and £5 for some new brake fluid its not too bad lol
