Hello,
thanks for all the replies, I've now separated the carbs from the frame and replaced the O-rings but they're still leaking - maybe I've used the wrong size? Are they imperial? I'll blow through the upper vents to check them, too, Cheers, MikeJ 18

Hello,
thought I'd jump on the bandwagon here and ask if anyone knows the size of the O-rings on the carburettor connecting stubs (the black plastic double ended spigots between the carbs)?, Cheers, MikeJ 19

Hello Clem,
thanks for the reply. I don't know how to separate the carbs as they seem to be connected by a cross bar which is pinned to the carb bodies, from what I remember. Is there a way to separate the carbs without damage? Cheers, MikeJ 21

Hello,
thanks for the reply, but the overflow pipes are clear and will drain if the carbs are turned at an angle, so I don't think it's that. I've checked the float heights and the float needles are fitting o.k., so it's still a bit of a mystery, Cheers, MikeJ 22
CB350/400 / CB400F carb. leakage« on: May 22, 2017, 02:08:35 PM »
Hello Folks,
I'm restoring the carbs. on the seventies CB400F project and have a slow leak in them. The problem doesn't seem to be with the floats/bowls as such, but the petrol leaks over the outside of the bowls and then drips off the drain screw heads. The cast in (blank?)holes at the outer face of the outer carbs have petrol in them (the ones just above the float bowls in line with the fuel connectors between the carbs.) but I can't see if there's a leak in the holes or whether they're filling up from a leak elsewhere. Also, the carb. bores also seem to have some petrol in them, which wets the choke flaps. I've checked the floats, level pipes and float needles. any advice gratefully received, Cheers, MikeJ 23

Hello,
you can get replica parts from motocicliveloce.it, including tank and seat units in glassfibre but they're a bit pricy. They also do a beautiful replica Bimota swinging arm. Bimota classic parts in Italy may also have some original bits Cheers, MikeJ 24

Hello Dave,
thanks very much! CAD drawings much appreciated- it reminds me why I still ride bikes-the people, Cheers, MikeJ 25

Hello Dave, thanks for the offer, I'll send it a.s.a.p.
Titanium sounds posh Oddjob, but probably a bit hard to come by (and cut), Cheers, MikeJ 26

Hello again,
if anyone could draw around a spare plate and send me the drawing I could make an alloy version? I'd be happy to pay postage, Cheers, MikeJ 27

Thanks ST,
it all sounds a bit Hi-tech for me, I'll probably look for a slightly smaller gell battery but thanks for the info, Cheers, MikeJ 29
CB350/400 / Re: CB350F crankshaft oil seal leak« on: December 28, 2015, 02:29:38 PM »
Congratulations Roy,
there is a tool which looks like a handle with a flat shaft extending from it, with a 'beak' shape on each side which can be used to prise oil seals out, if you have the clearance, Cheers, MikeJ 30
CB350/400 / CB400F Battery« on: December 28, 2015, 02:22:11 PM »
Hello All and Happy Christmas,
could someone please tell me if there is a smaller, lighter than standard battery that will fit the CB400F while still allowing use of the electric starter etc? Cheers, MikeJ |
