Have fitted the K&N filters to both the carb and engine breather. On mine the larger main jet doesnt appear to be needed as there is no hesitation in in accleration or whilst on constant throttle settings however I will keep an eye out in case it develops. No nasty smells from the crakcase breather but the engine doesnt breath heavily anyway. A small but noticeable increase in performance which is a nice bonus. Over 150 miles so far with new setup. New shiny rocker cover fitted so underbonnet smarten up begun.(thank you ebay). EBC green stuff disc pad have made a marked improvement on pedal feel and braking. Thanks for all the advice, to someone new to Morgans, great chat room.
I haven't used the larger jet either, and there doesn't seem to be any hesitation etc. I rather like the new improved soundtrack.
Did you do anything with the exhaust manifold heat shielding? - I noticed that the HT leads sit directly above the hole where the hot air feed used to be and seems to direct hot air onto the leads, I wondered if it might be worth blanking this off somehow or ducting the heat away from the leads
Any thoughts?
