Bad news / Good newsFirst I want to thanks all those who have supported this endeavour.
The bad news...I've decided to stop supplying the filter kits. My costs have gone up again, and I can no longer justify the upfront out of pocket expense. The reality is I was underwater on the last order. With the move, starting to get some shop space setup, and prepping the sidecar for the coming season there are no funds available to continue.
The good news for those who want to DIY. Paul @
http://classicmotorcyclesolutions.com/ can/will continue to make the stacks available for the 500 / 550, & both versions of the 750 carbs (early & 77/78 PD's). You can contact him directly through his web site.
'edit' Sept 6/13 - I have contacted ITG (Andy Jackson: andy.jackson@itgairfilters.com ),and they will make filters on an individual bases - the P/N's are as follows: for the CB500/550 #JCJNBR/45, and for the CB750 #JCJNBR/55. At the present time these will come with an un-drilled back plate. I'll post drilling information shortly to this post. Orders from Europe will ship from ITG directly, orders from else where will come from the local distributor.

Drilling info - 1st you need to mark to horizontal centre line on the back plate, and find the centre point of this line. For the 500/550's you need to mark a 2nd line 8mm
above the first, this is your drill line for these. The hole spacing is the same for all versions: 75mm between 1&2 / 80mm between 2&3 / 75mm between 3&4. Start by marking the centre of holes 2&3 (40mm each way from centre point). Hole sizes - 500/550 41mm / early 750 carbs 44mm / 750 PD carbs 48mm.
