No power:(

[John]

Bah...

Tried ona long straight, over a mile...

whatever gear can't get over 30mph

Any ideas?

Thanks

[minesweeper]

What bike? if you have an nsr something must be wrong

[Ste]

Its a kawasaki AR125.

It pulled to about 75ish last week and then ran out of petrol

I'd start checking stuff like the carb cos i dunno how long that guy had it for and he was fairly blank abouts its years of history

[TGE125NSR]

Top end gone bye byes?

[John]

what? :@

[TGE125NSR]

When the top end of the engine goes

Piston and rings normally , the acceleration and top end are slow as!

[Kickstart]

Hi

The AR has fairly small ports so should give the piston and rings a fairly easy time. They could have failed, but not that likely (unless you have been reving the engine hard from cold).

Basically first give it a good service. Clean the air filter, clean the exhaust out, put a new plug in, put fresh petrol in, change the gearbox oil and then see how it goes

All the best

If you had to switch to reserve at some point, then there's a chance some crap from the bottom of the tank managed to make it's way to the carbs.

Does it feel as though bike is running out of fuel?

Err yeah I should probably say that its fixed in that respect now, dunno wot he did and is good for 80mph

However it doesnt seem to want to start now...

[John]

Was fixed

Dunno what's wrong with it now.

After it was fixed it became quite hard to pull away, had to be very careful with the clutch or it would stall, it wasn't like that before it was fixed, quite strange.

[Robby]

sounds like your carb needs a good clean.

However there are easier ways to clean it that may work.

First off try undoing the drain screw at the bottom, and drain the carb out into a plastic cup or something. Look in the petrol or petroil there for different coloured droplets sitting in the bottom of the cup. If there are any, this is water, and it never helps to have water in your carb.

Also try chucking a bit of redex in the tank and see if that helps it.

If none of this works, get the carb off and give it a good strip and clean.

[John]

Took the carb off totally yesterday, cleaned it all out.

Funny thing was the bike didn't seem to be getting any throttle, rolled it along at about 10mph then went into 1st, the engine seemed like it was starting, then just had no power.

I think the powerband has been adjusted by mistake or something?

Any __useful__ ideas as what may have happend?

It had very very little power low down, but shot off to 65mph no problems, pulling very hard indeed

Then i stalled it and it wouldn't start

[McJamweasel]

No, no, no!

Green wunz wif Red Stripes go fasta!

stfu!

[Hex]

Well you did say a very silly thing, didn't you.

I assume the throttle cable is tight and is working the carb?

When you cleaned it did you assemble the needles, jets etc correctly?

Yeah they're back right

or were, will check again i tihnk

also what oil does it need? the light comes on if the bike is tipped, so i guess it's low!

thanks

[Kickstart]

Hi

Your bike is quite old, and possibly hasn't been used for a while. Water accumulates in the petrol and rusts the tank, and the rust gets into the carb.

I would clean the carb out again and put a fuel filter in. I would also be tempted to drain the fuel tank full, and only put back in the decent fuel (you will probably see "bubbles" at the bottom of the fuel which is water).

Also your AR doesn't have a power valve. Depending on what has been done to it in the past (such as a Micron exhaust) it is quite likely that the power will come in with a bang at high revs. As such you soon get used to slipping the clutch loads when you move off.

For 2 squeak oil just use a decent quality normal 2 stroke oil. I wouldn't worry about using synthetic 2 squeak oil in it. Not the 2 squeak oil will go in a tank, the gearbox has its own seperate oil.

All the best

Keith

Thanks Keith!

The oil light is telling me the 2 stroke oil is low then? Does it use any other oil/need any other oil changing apart from the gearbox oil?

Also, any ideas why when the bike was doing a maxium of 20mph hardly any slipping of the clutch was needed, it'd pull away easy with almost no revs.

How would you suggest that the tank is emptied? Also, where can i get a fuel filter, where would it go, and would it affect performance?

Thanks

[John]

And a few more questions,

Do you know where the adjustment for the idle rpm is?

Are there any other adjustments? I was told there was one for the amount of air getting in, or something similar?

What make spark plug should I buy, or doesn't it matter?

And finally, how can i clean out the exhaust, and is it a good idea?

Thanks very much!
