Mick, I make up a plate from thin aluminium (1mm approx) the length of the number 1 to number 4 extractor outlets (plus 2-3" ) and slide it in between the inlet manifold and the extractors until it jams in against the head with a bit of a light tapping/wacking to conform to the extractor bends. This has the plate seating against the head firmly. Mark the distance to the front face of the carb in front of each carb and scribe a line along it. This is the bend line to form a flange on the undershield.
I then get a sheet of 3-4 mm aluminium and mark the centres of the carb throats and bolt hole locations for a vertical face on front of the carbs that extends up to the base of the bonnet with a small rubber flap to seal there. I make the under side extend down to just near the rail and put a rubber seal on there as well. The horizontal section is then trimmed of to leave a flange that can be bolted through onto the vertical section. This seals the extractors from the intake area and keeps any fuel leaks of the exhaust. :-) Cheers Feral Errol -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of mick ralph Sent: Tuesday, 29 January 2002 12:24 AM To: [EMAIL PROTECTED] Subject: Re: Radiators/UNDERheating? Hi errol Thanks. I should install a proper gauge I guess but the issue of extra wear is disconcerting. I played around with thermostats a while ago but I'm starting to think that this may still be the problem as i did a run from brisbane to gold coast (about 45mins) at 5000rpm all the way and afterwards i could rest my hand on the radiator and the rocker cover was not really 'red hot'. Doesn't 'smell' hot either.. I'll check the thermostat asap thanks again cheers Mick PS U got any clues about heat shields and air boxes for 45 webers? ----- Original Message ----- From: "E Smith" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, January 28, 2002 6:23 PM Subject: RE: Radiators/UNDERheating? > Mick excess cooling can cause high engine wear rates through the pistons not > expanding enough to conform properly to the shape of the bore.
