Not sure what sort of fuel lines your hoping to get Jeff. I shall probably go the copper pipe way like my single carb has at the moment it looks original and always looks nice when polished. This could be rather fiddly and I'd think that rubber pipes would be so much easier to fit, but hey... Bit of time and patience eh!
My latest news is that I have just had my magneto back from a full overhaul and rewind (soooo much better) I'm now on the lookout for a right side carb to match the left one, the carb fitted in the photo is a 276 DP/1A 15/16th bore, I've just got to get a couple of drip trays and cable links and then I should be ready to fit. Keep us posted on how you get on!
Brian... An interesting idea of running a fuel line from each side of tank direct to carb, the only snag is what happens when your low on petrol? Obviously at some stage one side will stop running, I'm wondering if it would be okay to keep the bike going on one cylinder untill next petrol/gas station?
