Airfilter adapter

[fossie]

The airfilter for the 400/ 250 Kat is 13780-45D00. Which is available but can be a while to arrive .
The alternative is to buy a GS 500 ( twin) airfilter 13780 01D51 and use one of our trumpets that simply fits in the top and you can adjust to suit .
This item obviously can be reused in next filter saving in the long run .
£15 incl postage buys the trumpet .

What exactly is the purpose of the trumpet? It can't be to tune the intake length?

[fossie]

It is to increase the volume pressure intake .
If you slip the trumpet in the filter all the way out and start the engine it sucks it down adding pressure through the filter to the carbs.

When I first got my 400 filters weren't available and we hadn't made the aftermarket adapters , I just found a connection from an old VAX Hoover was the correct diameter and cut it to length...adjusted it a few times, it was still there when I rehomed it 120,000 later .
There was a flat spot without it , gone with it ....until the carbs wore out, literally ..
