Gday all,
Top site and a hive of collective wisdom it seems. I hope someone can help me work out what is going on with my 07 GSA (Sept build) with only 3000 klm's on the clock.
Riding between 3500-4000 RPM and above the engine rattles/knocks very loudly.
This is my second GSA as I wrote one off on a trip riding over the Top Of Australia last year
I did over 30,000 klm's all up on her without any noises like this bike emits.
I'm using 98 octane and the rattle has nothing to do with pinging which I'm familiar with.
Put it this way, my Norton commando rattled and knocked like this GSA dose before the mains went west with the rotor taking out the stator.
Question is do I have a out of spec motor? It sounds like loose gudgeon's and piston slap. Of course I'll have the dealer look at it (again) but the head BMW mech has already test ridden it and I could tell he was reserving his comment.
This bike also has a buckled rim from factory which is being replaced under warranty and was way out of spec so much so that it wore a brand new Metz Karoo out in only 2500 klm's.
To top it off the bike had two missing bolts (Rear Rack and one Crash Bar) and all 4 lower triple clamp bolts were just off hand tight (noticed when backing bike out of the shed and the fork tubes were binding/twisting in the clamps. I've since gone over the whole bike with a torque wrench using my Haynes Workshop manual Torque specs. Found several other loose bolts as well.
What do you blokes reckon? Anyone heard of any other engines leaving the factory out of spec like mine is? It seems this bike has definitely been slapped together. I have read of blokes with similar bad engines but never heard of any outcomes.
I raced a GSX-R-600 for 3 years in the State Champs and Blue printed the engine myself and have rebuilt everything from a Chev 350/ Jaguar V12 to the mighty Norton but I'm finding it hard to come to grips with a brand new bike sounding prematurely worn out like this and being such an expensive bike like the BMW, I was under the impression quality control would be above average.
I'm genuinely concerned the bike might buck me of if something lets go in there. I have taken some sound recordings which clearly indicate something ain't right. Valves set spot on and head torqued to factory spec so I've eliminated every possible cause of this rattle or have I?
I love the GSA's obviously as I got another after the first one failed to bounce and hope BMW do the righty and replace the engine as whole rather than fitting a new piston or what ever.
Thanks in advance

Here's a pic of what happens when a big heavy pig like the GSA bucks too hard.

I hit a dust bowl with a concealed ledge on the exit (gazzetted outback Australian road)and to this day i don't know if the swingarm broke causing the bike to highside me or what?
Thanks for that Chief. Good to see a web site devoted to all aspects of BMW ownership good and bad but at the end of the day as long as BMW do the righty allsgood.
