Does anyone have the BMW tool to pull the cap from the spark plug ( the secondary coil over the plug) or know a way to pull it off without the tool and without damaging the secondary coil?

Goldie has 1

i have one if it is the same as the F800

Thanks I managed to get them off by Looping 2 cable ties around them as a puller
Will have to get one for the tool kit as that was less than ideal

Thanks for lending me the secondary coil puller Mike, and a big thanks to Nev for mechanical assistance, good advice etc. It took a little longer than planned, 5 hours instead of 2, but the new cam sprockets otherwise known as "Rocket Sprockets" no relation to D.Sprocket, are now installed

Purchased from Boxer-Performance these sprockets change the cam timing by 9 degrees which has the affect of bringing the peak torque in about 1000rpm lower. This gives the bike better low and midrange response. I went for a good blast this evening and the best way to describe the effect is this...

At 3000 rpm in any gear twist the throttle and the standard Cam timing of the 1200GSA delivers a smooth but steadily increasing acceleration. With the timing advance sprockets the same scenario delivers and instant steady kick in the back acceleration. Ie you don't get the sensation of the power building up it just comes on strong straight away.

Anyway early days yet and more km to do before true assessment of the change in characteristics. There are lots of posts with positive feedback on ADV rider about these sprockets, sometimes referred to as Lennies Sprockets after the guy who makes them, based now in Melbourne.

Nev you need to take the GSA for a spin, I think you'll be impressed.

This is the Boxer Performance site if anyone wants to check it out.
