I have just finished rebuilding my 1600 TP, my bottom tin aint great, as Im running J tubes it just sits there and does not seal as the heat exchangers are not there, so it appears to be neither use nor ornament, I reckon it will be OK to leave off. What is the consensus, Cheers Dave
got none on mine - type 4 running j tubes - didn't realise it had to have any lol, to be fair i haven't got a clue what bits are missing! all my heating is gone including fan to the windscreen so i imagine there's loads more bits off. the temp runs at 350 degrees farenheight according to the cylinder head temp gauge.
