V7 Muffler Fire

Cut me down if I am wrong, but a TB loose is different to a TB that has fallen off!
If the TB has fallen off it will give full airflow but less petrol as the TPS will not be fully open.  So I would have though the engine would have a weaker mixture than normal?

Or if the TB had fallen off would the lambdas run weak so that they made the ECU demand more fuel....?

Well, of course, you are right.. but a throttle body isn't going to just fall off..

So I would have though the engine would have a weaker mixture than normal?

Certainly, that *cylinder* would have a weaker mixture.

You would notice somethong is wrong of course, how soon you would notice depends on the variables

Hi Chuck,
Roy said the TB blew off due to a backfire.....and the later V7 bikes only have 1TB so with no TB attached there would be full airflow to both cylinders......rath er than excess fuel??
