    I never bother. I have NEVER found a clogged  injector on a BMW.

Realizing that clogged injectors are rare, I would however like to let it be 
known that it can happen. For me, it was on my 1100GS with about 50K on the 
clock. This was determined by the dealer who was able to diagnose the problem by 
replacing the injectors, and by process of elimination, determining that one 
injector was clogged. 

The culprit appeared to be a K&N air filter I had been running for 40K miles. 
(I switched back to, and have continued to use only OEM air filters in my 
bikes since then.)

About 10K later, the bike once again started running poorly, in the same 
manner previously caused by the clogged injector. Installing a new throttle cable 
resolved 50% of the problem. To resolve the remaining problem, I ran a couple 
of containers of STP Injector Cleaner (the black bottle) over the next 4-5 
tanks of gas. Problem solved, to my surprise and relief. (Injectors cost over 
$200 each.)

I now routinely run a bottle of STP Injector Treatment (the white bottle) 
between every oil change, pouring in 1/2 bottle per tank beginning about 600 
miles before the scheduled oil change to avoid having this chemical spend too much 
time in the crank case due to blow-by in the cylinders. I follow this same 
routine with my cars as well. At less than $2.00 per bottle, I consider it to be 
cheap insurance.

I understand that a lot of riders follow this same procedure using Chevron's 
Techron Injector Treatment. I'm not qualified to say one brand of injector 
treatment or cleaner is better than another. I can only say that STP worked for 
me, and therein lies my prejudice. Better Living Through Chemistry. Naturally,
