Smokn Easy Adjust Idle & Air Mixture Screw Twin Pack for 2 stroke Keihin PWK Carburettors
This idle & air mixture screw set replaces the originals to give quick easy access to your tick-over speed & pilot air circuit without the need for tools or even removing your gloves.
After the success of our Easy Adjust Idle Screws we manufactured this Easy-Adjust Air Mixture Screw to compliment it.
Both have been designed to be the perfect shape & length to allow for quick easy adjustment in seconds rather than having to stop & dig out the toolkit for a screw driver every time.
You can now have total control of your Keihin PWK carburettor settings without the need for tools.
Originally launched in 2011 with thousands sold worldwide, they are tried & tested designs made in Scotland from Aerospace specification aluminium alloy on the latest CNC machinery working to ridiculously accurate tolerances. You will not be disappointed!
What are the benefits?
Idle Screw
Warming up
Engine idle speed varies as the bike heats up to normal operating temperature.
If the idle speed is correct when fully heated up it'll be lower when the bike is warming up causing it to run poorly, stall or even foul a spark plug.
Simply start the bike from cold, turn the idle screw in by 4 flats (360 degrees) & leave it to warm up quicker & smoother on a higher idle.
When you're ready to ride turn the screw back 4 flats to return it to normal.
Climate, temperature & altitude changes
2 strokes are sensitive to climate, temperature & altitude changes, even one long hill climb can alter the way a bike runs. You can compensate for this by raising the idle speed so that the bike doesn't cut out on tick-over.
Racing
Some Enduro racers like to increase the tick over speed on special tests to reduce the chance of the bike cutting out, now its a quick easy job.
Washing
Internal corrosion is a major cause of engine failure in 2 strokes so running your bike up to operating temperature after every wash is essential.
Raising the tick-over speed slightly speeds up this process & avoids fouling the spark plug.
Air Mixture Screw
Climate changes
2 strokes are sensitive to climate changes & this can alter the way a bike runs.
Correct adjustment of the Pilot air circuit can make a huge difference to the way the engine responds.
This screw will not teach you how do do this properly but if you have (or acquire) the necessary skill it will make the job a lot quicker & easier.

Please see the larger image in the main picture for the finish that you will receive.
The ones with the coloured anodised finishes are slightly more expensive than the polished ones to cover the cost of anodising.
All colours shown are available in our eBay shop, if you can't find the ones you want just drop me a message.
Please check your own carburettor before purchasing to make sure it is a Keihin PWK as manufacturers sometimes swapped between carburettor manufacturers from year to year.
