Yesterday I collected my 'new' 1150GS - it's so good to be back on an 1150 after 3 years (and a misguided attempt to like a 1200 - they give me back pain after 20 minutes riding:eek:).

But I think the bike is weird. It's a 2002 model (probably), single spark, registered December 2002. Black engine/gearbox and SERVO BRAKES :confused: But I thought servo brakes were fitted only to twin-spark 2003 models? Or have I got a rare "let's see how it works" bitsa change-over model? It's had a new servo pump fitted already but I'm not sure it's going to stay fitted for long - the brakes are very effective but I'm not a servo fan.

The other thing is that it has a JAH gearbox which isn't mentioned here:

but it's black with a long 6th. And it's incredibly smooth-changing - far better than the 'box on the '09 1200 that I rode last weekend and in a different league to how I remember my old (2000 model) 1150 being. It's had a gearboxoil change recently as part of the 24k service so maybe that's something to do with it, but I doubt a main dealer would have put in anything other than 'standard' gear oil.

Things I've discovered since collecting it last night:

1. There's no 'key' for the aftermarket oil filler - circlip pliers and a return to an original filler plug on the cards.

2. There are no rubber plugs on the throttle body balancing stubs - it didn't run badly without them but I've taped them up until I can get replacement plugs. And I should check the spark plugs to see how lean it's been running.

3. I LOVE 1150GSs :D (I knew that anyway, but I'd forgotten how much)

It's good to be back. Forgive me if I ask some stupid questions as I investigate the bike further, although it's all pretty familiar stuff.

I don't think that the list is complete. I have a spare black, low 1st, gearbox that is marked JBH.
 
What's the difference between the long and short 6th?

At 80mph (GPS speed) mines turning over 4,000rpm in 6th - seems quite high but still pulls Ok!

I don't remember the figures exactly but I think mine (long 6th) was pulling about 4,750rpm @ an indicated 100mph (speedo, not GPS) on the way home last night. And 70mph was somewhere around 3,250rpm. Acceleration isn't too hot in 6th but it's very relaxed for cruising.
 
04 GSA .... low first and sixth gear. At 70 mph bike is just under 4000RPM ... around 3800 I think and at 90 mph (on a closed private road :augie) just under 5000RPM. Pulls fine in 6th!
 
and thats exactly where im off to now, escape the house and chat to the bikes, they make more sense.
