I have a 2004 R1100S which I wrecked in August of this past year. I came up on a turn which tightened up dramatically and I pretty much forgot that I was riding with bags and laid the bike down trying to make the turn until the right bag hit the road, which I’m thinking the right cylinder would have hit at about the same time. But long story short I was fine, the bike not so much.
So I started the rebuilding process by rounding up parts here and on EBAY and BeemerBoneyard. I got the aluminum cage and the upper shock tower and in addition I needed an ignition switch and a gauge cluster and from there mainly it was just plastic.
So I get to the point where I’m ready to make the bike a running ridable / rolling machine before I proceed to start working on the bodywork. I was unable to crank it after the wreck as the ignition switch was destroyed, so this was the first time it would run since the wreck. When I went to crank it, the thing was not running right. Basically it is misfiring on the right cylinder. While it is running it is spitting back through the intake and popping out of the exhaust sporadically. Before you start suggesting coil stick / coil / plug wire, I have spares in that I took the sticks out of my R1200S and I just so happened to have replaced the lower coil with new wires a few months back and I still had my old ones.
So between those and swapping from left to right I came to the place where I knew my problem was the right cylinder and had nothing to do with wires or coil. It sits there and pops and spits until I unplug the two plug wires on that side and then it sits there and runs on the left without drama as in spitting and popping. If I do the reverse, which is to getting it running and so much as disconnect one wire on the left cylcinder it dies immediately, it will not run on the right cylinder.
So I pulled the Fuel injector out to make sure there was gas, I even swapped the injectors from side to side, still no change. I just had the injectors cleaned and calibrated this past winter by RC as they are RC310’s. I’m not an ace / expert mechanic such that if I was I would not be asking for help, but I know when you have fuel and you have fire and the thing is not running right, typically the fire is happening at the wrong time or something in the combustion chamber is not where it should be when the fire occurs.
So I take the cam sprocket cover off and line up the arrows on TDC and check the valve tolerances and they are totally in spec per the last time I adjusted them, which kind of blows my bent valve theory. At this point I was sure if I just pulled the head off my problem would be glaring at me, but I knew one more thing which needed to be done and that was run a compression test on it. I had to borrow a tester from a buddy and last night I checked it and I had exactly 229 PSI on both cylinders. As much as I was glad that I had 229 it made me realize what I thought I was sure of was no more and that it was back to the drawing board or I guess in this case the Pelican Parts Message Board as I’ve never asked for help before.
I’m not sure if it is accident related or related to what was replaced after the accident, but I’m not sure where to go next. One thing of note, and that is the tach is not working and I felt like that was a problem I’d deal with later. Does anyone think it could be related. I’ve checked all the grounds and pretty much everything you can check visually. I don’t see any to reason to pull the head at this point. I’m starting to think that even though I have everything you should have to make one run, gas ,fuel ,fire, compression that perhaps the fire is not occurring at the correct time.
I remember reading somewhere way back when about putting a plug on a coil stick and rolling the engine around to see if it fires or sparks when it hits TDC. Anyone have any other idea’s ???
