Look that the size of that thing!!!!!!!!!!!!
The new filter in place
Looks cool
The old K&N filter
Yesterday at the Wheels day Martin found himself a new air filter for his Pilgrim Sumo when we were looking around the trade stands.
So today we had to try and fit this monster of an air filter, the thing is the size of a dinner plate!!
With the old K&N filter removed from the carb we could see that we would have to use the base plate from the K&N filter to get it fit to the Weber carb. A couple of holes had to be drilled into the base plate of the new filter to pick up on the mounting lugs of the K&N base plate, once this was sorted out the next job was to get the height of the filter right so that the bonnet would shut, at first the filter was way too tall to allow this, so it was out with the die grinder and a good 1/4 of an inch was cut off from around the lip of the new base plate inlet hole.
With the two base plates fitting together nicely a flat piece of metal plate was used between the two mounting lugs to support the filter lid, once it had been drilled and fitted, the stud that holds the whole thing together on the new filter was cut to the right size and a M6 thread cut onto the bottom part of it and then bolted to the support plate.
Now to see if the filter would fit?????? The modified base plate was mounted to the carb followed by the filter element and then the chrome lid and locking nut it was the moment of truth.
With fingers crossed the bonnet was gently closed and then locked home all had worked out well,
a job well done.
