Thanks for the info guys. Downpipes, collector box and silencers are all available but the covers to hide the collector box are not, that would add about £350 to restoration cost, the existing two into one is in good condition so something to think about.

I am restoring a 1981 CB 250 superdream. It has an aftermarket two into one exhaust system. I think that all models had two into two, can anyone confirm this?

Yes I had this problem, the bigger tap is quite hard to find I eventually got a new one from a German ebay seller - not cheap but a good quality tap

I am in East Devon so about 40 miles away - any 500/550 owners in Devon?

I see that dss has a 4 into 4 in stock for a 550 K3 - would this fit a 77 f2?

Make sure you get a temperature controlled iron and don't use the lead free solder

on my 550F I am getting 4000rpm at 55mph with 17/34 sprockets - I dont think the tacho is very accurate on these bikes though.

Like an idiot I managed to drop the bike while on loose chipping, got it upright tried to restart and after a bit of a rattle the engine stopped dead. Anyway after a complete tear down I found a nut jammed in the primary chain - looks like a cylinder head nut to me and although I have had the head off in the past I know I have not dropped a nut so I can only assume that the nut was stuck somewhere in the lower crankcase for years and was only disturbed when the bike tipped over - all very strange but the good news is that it is all up and running with new primary chain, oil seals, cam chain etc, not a job I expected to be doing though.

Thanks for all the info - looks like adding some seafoam will do no harm so I will try that anyway. Anyone using high octane fuel, any gain in using it?

I am often getting sticky fuel valves, the petrol poors out the carb but is fairly easy to cure by giving the bowl a tap. Is this a common problem? Carbs were stripped and cleaned a thousand miles a ago. Is it related to modern fuels perhaps they are drier if you know what I mean. Anyone using any aditives in the fuel or using the higher octane variety?

Thanks very much for your help, I will see how it fits when it arrives.

Yes it was fitted as shown when I serviced the the head - I had no idea that the pins should have rubber on them, I take it the new one should have the rubbers which should cure the problem?

Thought the bike was rattling a bit more than usual and on inspection I found the broken cam chain front guide, the adjuster seems to work as it should and I can't see any other problem. Anyone of you guys seen this before? wear and tear or what might have caused it?

It never slips out once the gear is in and its when riding, I haven't tested on the stand, as it doesn't happen every time I am wondering if it's a clumsy boot problem! My last bike in the 1970s was a triumph so perhaps not used to left hand gear changing. Anyway, I will check gear selection on the stand and also the lever position. Thanks for the advice guys.
