InDuct & power flow filteron, otherwise stock 2001 R11S, will it run too lean?
 

I have a 2001 R1100S. It is completely stock but, I have a Power flow filter coming and may get one of those InDucts. My concern is that the bike will run to lean. It still has the Cat and O2 sensor.
Any suggestions?
Later going to get the Vanderlinde exhaust.

Here's a thread that might help you.

I see that this particular person on the thread is using a K12RS fuel regulator, so he should be getting more fuel than I would.
Am I correct?

Yes that is correct, cost $60 plus your time.

JOE http://www.pelicanparts.com/ultimate...oads/MINIS.jpg

Yes, more fuel. There are a couple threads on that too. Although until you do the pipe the amount lean is going to be relatively small.

In some sense FI makes the fuel thing MORE work than a carb since its not a closed loop system, or even on that measures mass air flow.

Jasper,

I ran the original InDuct about 2 1/2 years ago with an aftermarket Foran exhaust, cylinder head porting, disconnected O2 sensor, and later a K&N filter with the stock chip for about 18 months. This is not to say it was not too lean, but it did not seem to have any detrimental affect on the engine whilst providing good power. The motronic will compensate to a certain degree, but the real gains for any change will benefit from a chip change.

I still run the stock chip with an increase in fuel pressure that seems to improve the combination. The next thing is to custom tune the bike for its current setup.

what's the difference in psi between the S and K12RS fuel regulators?

Thanks.

Mal

The S runs at 3 bar and as far as I understand the K runs at 3.4 bar.

Can someone post more info on the K12RS fuel regulator. Cost? Install procedure. other useful info. Thanks.

I have a laser mid section with TBR Carbon Cans, I also have a K&N filter fitted and a K1200 3.5 bar pressure reg with the O2 sensor still connected and original Motronic chip. I have advanced the ignition timing also and run on 97 octane fuel.

The biggest difference I have noticed with the changes is that it is much more willing to pull at higher engine speed, that's 5000rpm's to the rev limiter and it will fly up to an indicated 150mph. (Track only of course;-)) This may not be useful in everyday riding but it does help to keep up with your buddies on their jap missiles.

How dos one 'advance the timing'?
I was under the impression that that was one of the functions of the chip.There is a seperate adjustment?
Oh, goody!
Dish.

Por favor, of course...

jeff
needs something else to doink with...

The timing advance instructions are on the IBMWR site under the tune-up and tuen Super tuning techniques...

I'm dying to try it to mine but its still under wanrantee and I'm pretty certain that fiddling the ignition timing would not be a good thing if the engine went south.

It's dead easy. Take off the front plastic cover, undo the three hex screws on the timing plate, twist and retighten, takes about half an hour.

Hi,

Yes, it is dead easy. I'd say Rapt is right that a misadjusted timing setup _could_ void warranty. Most likely only if you holed/burnt a piston or valve though. The combo of too much advance and leanness would be plenty cause for warranty denial, so I'd be careful about that combo.

To answer Mr. Clark's question, yes, timing variation/advance/retard _is_ done under engine control. The base mechanical static timing can be adjusted though. The engine computer will vary the timing from whatever mechanically set baseline you've dialed in.
