But again, I don't argue of "the feel". But again I'll point it to different factors other than the cooler air intake.
You're talking shite.

also why cages air intake is usually just behind the grille not next to the exhaust.
exactly what I was trying to get across, 100% bang on , therefore my point been on the opposite ie high temps the bike would run a bit rougher

Yep I know the Bandit has carbs My previous other mentions referred to a K6 and a Busa but the principle of what I was asking was the same

And Jaded just as you said and Allsorts above , on the frosty mornings you noticed a diff on the old carbed bikes,
so long story short, I put it down to filling up in the local Agreens as opposed to another garage,for what I was asking anyway in the op

Re-reading my comment I should edit as the turbo really comes after the turbo, but other than that it's pure fact.

But then again, if you gain 50hp on a cool day. I'm happy for you

Yep, def runs better in the cool of the evening rather than the full heat of the days we have had.

I always found my 350 YPVS ran waaaay better on frosty mornings/nights and even ran better at night than by day.
Air expands when heated so cooler air means more oxygen which means more bang(and that's always good )

I am only guessing but it could be the additives they put in that is actually good for the new and newish 0-10 year cages on the road but not good for our auld ice lumps.
They put crap in the fuel to stretch it and make more profit.They're all at it.
Best bet is pay a little more,although more cost isn't always better.
A lad told me they're adding animal fat to diesel now.God knows where it'll end.

Bikers tend to be one of the worst culprits.
But ex-bikers (had a 100cc piece of shit in 1983) take the biscuit.

You do know that different petrol stations can fill their tankers from a different companies tanks down the docks if their own holding tanks are out right? On a 'get you back when we get our tanks topped up' system

They do it all the time, but I thought they actually buy the fuel from their competitors, as opposed to borrowing it.
It's why boycotting certain stations (suppliers) is pointless, because this means the extra load goes onto the other suppliers, who then have to buy the extra fuel they need from the company you boycotted.
