Firstly, Hello everyone. My names Olly and I've got a '79 T140 currently undergoing surgery in the Uk.

Now to the problem. Someone must have encountered this? The parallel port T140 Bonneville doesn't have enough room between the Amal MKII bellmouths and the OIF to fit normal conical type filters. I've spent a lot getting my head to flow right and will be tuning the inlet and exhaust lengths shortly so I'm not about to make up some splayed manifolds or ditch my head for a splayed inlet. Anyone got any ideas on this one? I can't run the intakes open has I've got some expensive parts in the head that I don't want to be replacing too often!
 
I should have said, the airbox and side covers are long gone. I just have a small alloy box containing a dual output coil, EI unit and a gel battery.

I've been looking at foam filters by Ramair and Pipercross. Ramair make a filter that is meant to fit over the stacks on a Webber DCOE that I'm fairly certain would work. The problem with all of this though is trying to find the exact model of K&N that will fit out of the thousands they make. I don't want to take a chance when a single filter is going to cost forty pounds.

I've run MKIs in the past and in my opinion they peform poorly in comparison to the MKIIs. The only other carb I'd consider running would be the Monobloc but I don't want to go back in time.
 
There's only one solution to the filter problem on that motor - a Rob North Frame.

They just look so right in a way that a normal splayed head looks old fashioned.

OK so maybe not the cheapest solution, but it isn't my money I'm trying to get you to spend. Are there any Pipercross or similar Weber filters that might fit. I don't know the spacing but maybe a filter for a side draught DCOE might do the job
 
It's be nice, I saw a weslake 850cc rob north the other day, it was quite something.

I've seen two options, one the tie on filter and the other the rubber mounted filter but the later is longer and may foul the OIF but that shouldn't be a problem if its foam. My one concern is that they may try and collapse but that could easily be remedied with wire.

Ram Air have a good rap. They are like UNI that we get in the US. UNI usually have a spring inside and that helps a lot.
 
Sorry Swivel, I misunderstood, thought you meant MKIs. I don't think I'm familair with MKI I/2s, they still made by Burlen/ Amal?
