So, it's been a little while since last I wrote - how have you been?
Logically it had to be the filter, so the intake was kept clean. I'd bought a carbon fibre air filter from CBS just before Christmas, it came with a lightweight stainless clamp type mounting, but I drew up a couple of brackets & made them out of 1mm aluminium (with stiffening flanges) that mount the filter to the "shelf" behind the engine. It was an easy fit, it weighs next-to-nothing, so four 4mm pop rivets is sufficient & I also cut & fitted the aluminium trunking that takes the clean air to the airbox. It's surprisingly stiff so need no additional support. Not sure how long it'll survive attached to a vibrating engine, but it should be OK.
Things still to do:-
Shouldn't take long then should it?
