I would imagine they are repro hm300's with single-skinned headers. Much less forgiving when you're dialling in the carbs after a restoration...

Pretty sure Pete but I'm no expert so could be wrong...To be fair I've seen OEM Honda HM341's (double skinned headers) 'blue' with poorly adjusted carbs in the past...

I didn't know they were single either.
the main difference is he has 3 coloured up and one clean.
I seem to remember if nunber one was blued the "excuse" then  was heavy breaking
and the heat coming from the disc caused it, Don't know
if true or not though.

I run a CB500-4 ,with genuine HM 323 pipes,

all 4 have blued and tinted,the plugs are a nice biscuit colour,

when I fitted,or remove the pips,they look single wall,

I have heard the lead free petrol runs hotter,???

I fitted single wall stainless down pipes to my Laverda many moons ago, and they were blue within hours--nothing to worry about. I think what this guy needs to think about is---is it only running on 3 ?!

Sorry Guys
Not ever have genuine honda exhaust systems gone blue with me.If its happened with you, you have problems not even running for hours in a garage has that happened.
That is why I hate Brit bikes cos they blue within minutes
