Header Colour(Color)
I have recently given my headers the once over and they were looking good.
I went for a lengthy ride and flogged the bollocks off the bike.
Happy with the way it went but somewhat mystified in the difference of the colour between the front and back headers.
Is this caused by the fact that the rear cylinder runs hotter than the front?
I thought that I had taken care of that by fitting a bigger jet to the back carb in the belief that more fuel equals cooler running.
Take a look and see the difference.
What I need is a definitive answer from some carb gurus on here!
Hawk, where are you?
Front Header
Rear Header
Who knows what the answer is , but sure as hell I would like to know!

I think the difference in color is totally normal and not due to the rear cylinder being hotter, but rather because when the bike is running the front header is exposed to direct air flow and gets cooled way more than the rear.
Retired- but not tired!

I can't see the discoloration very well, though just for general knowledge, if the specific cylinder runs rich, it will show up as blue colour on the header, or if it runs lean, it will show up more yellow colour on the header, it is a direct effect of the burning temperature the exhaust gas coming out of the cylinder.
Most Honda's actually running a little on the lean side from the factory.

Kenmoore is there anyway to route your hydraulic clutch cable away from the counter shaft sprocket?
I would hate to see you toss a chain and it takes off the clutch line.

In the picture it looks close, however in real life it's not.
If the chain was to go I would be in trouble I know as it would probably take out the line.
Just one of the many reasons I am so **** about my bike .
I check and recheck the bike before and after rides as I like to give it some if you get my drift.
Part of the reason I routed the line that way is because it looked terrible following the original route.
If you look closely you will see that there is a rubber grommet around the line where it meets the frame to stop chaffing, but like was said before if the chain goes the clutch will be useless anyway.
I threw a chain on a Z1R Mk11 that I owned once and I can tell you that I had to change my underwear, Bloody scarey it was .
