Question about 2001 BMW R 1150 GS

1 Answer

Possible to install R1200S heads and pistons on an 1150 GS ?

I am seeking to upgrade the engine performqance of my '01 R1150 GS. Could one do this by swapping out the heads and pistons for R1200S components (with an overbore if needed)? If so, (a) what other major components (if any) would need to be swapped too (e.g., con rods, valves, etc), and (b) what machining would be required? Alternatively, is there another BMW model whose engine components could be swapped onto the 1150 GS to increase the horsepower to 110hp or more?

R 1150 gs Adventure , no spark no injection . Fuel pump works fine , triggers checked with GS 911 looks good


Hi, Spanidishar if you have a CKP sensor it needs compression to send the correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in the head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm needs reset

No problem but I have a general question. I ride a 2000 R1150 GS and I have put 65,000 miles on it since new. I'm thinking there has to be a known by experience maximum mileage point for these engines...


hi,my GS1150 has 180000k's on clock and is in daily use and probably has never missed a beat. I believe i am looking at another 100,000 by the sound of my engine

Oil


Since the R1150 engine is entirely air cooled, standing still with the engine running for extended periods will quickly lead to high temperatures. This is normal and engine temperatures should be monitored to prevent excessive engine temp. This can lead to valve stem jamming in the valve guide, warping of heads, etc. I can see my engine temps increasing if I drive slowly (1st gear) in loose sand (high engine revs). You just have to monitor it. I haven't heard of anybody overheating an R1150 engine yet, but I suppose there is always a first time. Having an engine problem in the bush (here is South Africa we do a lot of off-road driving far away from civilization) is not a good idea.
