If you try to alter the natural (allowed for in the design) scheme of things then you CAN not always will cause your self problems, loud bang and pop=pressure, normal burble is dealt with quite happily by the diameter of the pipes.
It doesn't happen on throttle because the fuel mixture is burnt as part of a well timed cycle, on overun however this cycle is absent and the mixture burns at will when there is either enough present in the exhaust or ignition at a random point. 4 stroke (otto) cycle:- suck, squeeze,bang and blow, all in the engine its fine, unfortunately there is no easy way to control the bang and blow in the exhaust.
Ps cerruti Harleys are normaly a little louder because
a/ the exhausts are of a bigger diameter.
b/ they normally have a straight through configeration
c/ they are large Twins.
Agreed. The other thing to remember especially with big twins of an older design such as the BMW Boxer engine is that to get them through the tougher emission controls now they are running extremely lean (fuel/air mixture) as standard. My Beemer popped on the overun in standard trim - they all do that sir! That's with a restrictive exhaust and catalytic converter. I have subsequently removed those offending items ;) and modified the fueling to suit. The popping noises are still there which I have a personal preference for ;D just a bit louder due to the clearer pathway for the exhaust gases. The engine runs sweeter at low and mid-range revs especially, which was the improvement I was looking for.Quote:

Go onto a BMW forum and the stick given to the squids on pocket rockets is just as bad!
Dont forget about the power rangers !!!!!! they come in for it too!
Yes, it's a very bad thing! But admitting that you own a Harley is the first step to recovery. ;D[/quote]Quote:

Thankyou very much. [/quote]
Oh dont take it to heart I'm sure it was friendly banter - give him some back ;) :) :)
We need more ladies here on the forum even ones who ride Harleys (and I really am joking I've got nothing against Harleys at all, although my OH accuses me of being a secret Harley fan because I love Ducatis...strange man :o :o ;D ;D)

Cerruti. I wouldn't take too much notice if were you. I don't think Mr Builders view is the view of most of the people on here. In fact i'm sure Mr WB would even admit that he doesn't mean any harm by his statement. Wouldn't you Dan? I'm fairly sure it was just a poor attempt at humour?

I thought it was a very good attempt at humour ;D made me laugh anyway.
Cerutti, it would be a shame if you were put off a whole forum by one very mild bit of fun (with a laughing smiley at the end of it) !
Forums are supposed to be fun places and part of this is the banter that goes on between members. If you are a Harley rider, a BMW rider, a Ducati rider, a trike rider, a yellow sports bike rider (with yellow leathers) or a crasher after the flag on a track day rider, this all will be picked up on and merriment made at your ( and my) expense.
This forum is by far the most gentle that I know of, and it's great that we have such a diverse group of people and bikes.
Gerry ;)
ENOUGH!
This was ment to be lighthearted comment on a incedent. NOT a comment on forum etiquette.

I would have said 4 litres, but have you seen the price of petrol these days?
