1150GS '02 Rattling noise
 

Quick question...My bike rattles when I push it harder (like when overtaking a car)...is it just the gas's octane level?

Usually It's fed 91...should I boost it ?

?c?

Just try it.
If it is, its a cheap fix :mchappy:

I got the same bike as you o2 1150 GS. Mine always makes rattles too when i push it hard. I'm up on just under 80000ks . The rattle increased, bought it in for a service and asked them to check it out. Bad news:(
Got a hole in the valves and lost compression. Fix = $400.- a side, ouch.
I always run mine on 95 octane.
Hope that's not the case with yours.
