Phil,

There are many good suggestions here to remove the bolt.

I would try to have a large nut mig welded in place and remove the bolt that way. I would make up a coned protector out of a beer to cover from the cam to the access hole to stop anything getting intot he engine. The heat from the welding will also free up the loctite to aid in the removal. Use a length of pipe over the breaker bar and be sure to support the pivot point firmly with your other hand.

All the other ideas are good as well but this is a quick and simple way to get it out.

In all the years of selling the sprockets, this is the first time I know that this has happened.

What I can say is with all the sets I have changed there have been times where I have been very wary of applying any more pressure even with a pipe over the extension bar. When they break loose finally the noise is quite frightening.

As an example.

I went to the Sunshine coast 4 years ago for my brotehrs 50th. I met a customer with a R1150RT and after great effort I refused to apply more pressure and left it up to him to break the bolts loose. They did come loose again with the loud crack.

We started to remove the bolts on my brothers R1150R and thet would not come loose.

2 bikes and 2 different torques or loctite to hold the bolts in.

Since moving to Melbourne I have fitted 2 sets to a R1200GS and a R1200S and both came loose without too much difficulty.

As phoenixtexoma says, try to get the sprockets fitted as you will definitely have a different bike to ride.

A guy in Romania Dan Cata who does the throttle body rebuild kits installed a set. He now uses 5.3 ltrs/100 km down from 6 ltrs/100 km or an 11.5% improcement and this was 2 up riding over varied types of road and speeds.

Hang in and keep trying.
