best i do the cam chain adjuster mod when im in that far too.
thanks for the idea though.
Firstly - it's the intake tubes to the airbox are what you want. 1100GS or 1150GS are identical. Sometimes called 'runners'.
I did this conversion on my 'S' and started this thread with the results in late 2012.
I did so after a friend put me on to an RT forum where a chap had put GS runners on his RT and meticulously dynoed the results.
"Looks like the go for me" I thought and away I went with the 'S'.
Removing the bodywork is the longest part. Easy to reverse if it didn't work.
First thing I noticed was the easier starting and even idle.
Then the crackle in the exhaust note when I blipped the throttle. Cool.
Out the driveway and up a short hill: much less clutch needed. Onto the road and roll on the throttle. WHOA!!! Didn't have to concentrate to feel a bit more here and a bit more there. Was pie-in-your-face type improvement.
It's the best bang-for-buck mod I've ever made to any engine. My 'S' is otherwise completely stock.
I really encourage you to get on with it.
Would you get back to me with your impressions when it's done.
I actually have before/after dyno results but I'm loathe to publish them after the many naysayer opinions already posted here.
All the best and have fun. (follow my step-by-step pics).
Real torque curves don't have a first derivative. :-^)
