can anybody tell where I can find a how to, because I've seen it once but forgot where.

regards andrew

Hello Andrew,

what do you mean with "emission kit"? Do you mean die secondary air system (SLS)?

If so, you have to close the two holes in top of cylinder-head cover. And you have to close the vacuum port, wich switch the vacuum valve... (below air-box).
Look that the difference pressure system of the carburetors is correctly applied to the air-box at reassemble.

Thats it

yes that is exactly what I mean.
I can remember that there was a site with an how to.
futher more is there anybody who can explain how it works, or what it does.
At the bike I've just bought they just removed the SLS and didn't close the cillinderhead cover holes. wich results in a lot of bugs in the cover.

Try to close the holes!

How it works:

The gas, wich is exausted after complete 4-stroke cycle, runs through the exhaust mainfold. The holes you see in the cylinderhead cover brings in fresh air to the exhaust valves. It workes over "venturi" principle. The fresh air should burn rests of unburnt fuel.
On low RPM the valve is closed over some underpressure valve. On higher RPM the valve open, and let in the fresh air (from airbox) to this holes.

This stuff takes power from the engine, and brings wight . Simple colse the stuff and all is fine.

THANK YOU THAT IS WHAT i thought, but somebody said I was wrong.
I'm going to do that, but if anybody still can give that link i'll be glad

jepp,

very importent is the connection between the carbs (the upper reference pressure line) and the airbox on the left side. a simple hose should work. without or a bad connection, the bike runns, like it has no fuel. in my bike, the cover-bolts for the zylinder-head-cover looks like original-kawa-parts, so maybe your lokal dealer can get those one's.

Iknow those cover and hope the dealer has them.
another way to do it is to use a cupper pipe and put it between the 2 hoses coming out of the cylinderhead. this i've seen in the how to I'm looking for.
and the left hose os the airfiltter box once came with my bike and indeed it ran hopelessly
