That's fine. As long as you have ANY clarance, there shouldn't be any issues.

Part of this was due to the tires, michelin pilot sports, which have much better feel and stability than the Metzlers on the VFR. The bike tracks well through the corners and has a very comfortable riding position. It's a good looking bike, too, compared to the R1150R (imo, of course). Some issues with BMW bikes, though: they're massively expensive for the technology you get. The switchgear is unforgiveably misconceived -- even if you were to get used to its idiosyncratic layout, it's still a huge pain to use with gloves on. Particularly, the turn signal switches have almost zero feel, and it can get a bit distracting/dangerous. The antilock brakes were kind of dangerous too, in my opinion: when they actuate, you can feel the bike just lunge forward for entirely too long a distance, maybe five or ten feet at a time. It's as though the cycle time of the pulses is much too long, and it's not fun when this happens as you fly towards a hairpin with no guard rail between the edge of the road and several hundred feet of drop. This was not an issue on the VFR800, where the ABS worked very smoothly. Finally, the kind of power BMW gets out of its boxer motors is a joke. Sure, the R1100S is fast enough for most purposes on the street, but it's not fast. All that said, we're going to be picking up another R1100S along with an R1150RS in a few weeks, this time sticking to southern france and possibly corsica. Zach

Ah very true but then I wouldn't have known the difference about the "extra" hole! :D Although, now I'm already debating, maybe a carbon fiber intake would be better... much deeper sound I'm assuming based on the chemical properties of that verse plastic. Hmmmmmm... if I do decide to make the switch I'll go list sponsor this time (although I got an incredible deal, $100+ off). ted 1997 M3/4 - AFE intake, blue filter matches Estoril paint ;-)

It's detecting a mixture abnormality that's outside the range of normal operation. Problem is you can't tell if it's too rich or too lean with the Peake, but your dealer can with his equipment. If too rich there might be a stuck injector or misfiring plug in one cylinder. You could pull the plugs and see if they're all the same colour. If too lean it could be an air/vacuum leak. Given your recent experience with the secondary air injection I'd be looking for an air leak in that area. If you don't find anything obvious you'll save a lot of flailing around if you have a dealer mechanic run the BMW diagnostics. I've got some printouts from mine from some while back which read in part: Fuel control limit, cylinder 1-3 Mixture at oxygen sensor is too rich Oxygen sensor has reached control limit Fault not currently present Detected 2 times First fault detection 1h 6 min ago at: Engine speed 832 rpm Coolant temperature 70C Oxygen sensor heater 1 69% Oxygen sensor 1 0.409V See what I mean about level of detail?

Date: Mon, 28 Mar 2005 17:05:03 -0500 From: loweseaton@aol.com Subject: Re: [E36M3] 8.5 w LTW's all around? I had a long discussion on this very subject with a guy on our local BMW chat list. I never could get him to understand the difference between the bottom and the top of the tire, so I gave up. Maybe I will have better luck explaining myself this time. The road contacts the tire at the bottom. As you corner, the ground exerts a sideways lateral force on the tire and does indeed make the tire flex sideways. However, at the top, there is no such external lateral force on the tire. No force = no flex at the top. However, things are quite that simple. You will agree that the tire wants to center itself on the rim if it is pushed sideways - correct? So as soon as tire leaves contact with the ground, the tire will start to move back to center. Say the tire flexes sideways 15 mm at the very bottom due to lateral cornering forces. Will it still be 15 mm off center at the top? It can't still be 15 mm off center. It might be 14.999999 mm, but not 15.0. The tire has to come back to center eventually. How long does it take? That depends on a lot of things but probably tire construction and stiffness of the sidewall is most important. Now, I'll agree that the tire might not have enough time to snap back to center by the time it rotates around to the top. It depends on how fast the tire is rotating. But I will argue that it doesn't take very long. And I will argue the tire is closer to center than whatever the maximum deflection is at the bottom. The faster and harder you corner, the more residual tire flex you will experience at the top. All that said, bottom line is I don't think it matters. You might get some rubbing but I doubt it does any more than just light "polishing" of the tire. I'd check to see that you don't have some sharp edge rubbing on the tire but if it is just the stock (or Bilstein in my case) strut, no problem. I really can't see any harm in a little tire rubbing. You might hear it but your wheel will not lock up - it will cause an insignificant braking force. The tire won't self destruct - the rubbing occurs for a short amount of time - and doesn't occur at all when you turn the opposite direction. Thats my story and I'm sticking to it! ;-) Lowell Seaton '95 M3 -----Original Message----- From: Dave DeBuhr <debuhr@comcast.net> To: loweseaton@aol.com; E36M3 <e36m3@bmw-m.net> Sent: Mon, 28 Mar 2005 13:30:39 -0800 Subject: RE: [E36M3] 8.5 w LTW's all around?

Dave, I've had my tires rub with <2mm clearance, but I've run ~3mm without problems, but that's with R-compound tires that may have stiffer sidewalls than most. But yes, the tires do deflect some when you corner hard, so it's good to check the dynamic clearance also.
