Metal replacements for rubber intake manifold 350
Posted: 26 Jun 2023 09:12
Hi All
Thanks again for all advice on thread "Bogging down/ rough running problem" I think Mark (threadmbmm350s) got it and when I re read his post properly I realised the white wire that I had linking the two ignition boxes needed to be removed- seems to have made a difference...I have been very slow to work on the bike as other life been busy. I have been riding the bike a little but latest was a hidden split in the rubber connecting the front cylinder carb to the engine causing tuning issues and then finally loss of power etc...maybe that has been causing issues for a while...
My Question is: Are there replacements intake manifolds other than rubber ones from https://www.mdinaitalia.co.uk/M300155.html. INTAKE MANIFOLD 350 ? (£46.58 Inc. VAT)
I am thinking metal ones might be better. Mine were not that old but one split perhaps because I had the carbs using the airbox so they were supported by the rubbers going up to that BUT then changed to 'hanging' the carbs on cable ties with cone air filters. This is when the manifold split I think as I may have moved the carb up and down whilst it was tightly attached to the engine via the manifold....
Perhaps the rubbers are necessary as heat dispersers- metal would allow the carbs to get hot?
As always all info gratefully received- point me at a relevant thread if there is one - I have looked but not found one exactly...
BTW: Have a great Track Day- I want to come but have a boring work doo the night before and bike prob not ready in time anyway...! Last time I went on my Morini I'd just bought it and after a fine day on track, as I left the Park I turned left onto the road outside and the crank spilt! That fixed long ago by Nigel (?) up in Bromyard area...
Best wishes to all
Matt
