If you want to borrow my locking pins, I'd be happy to pop them into a jiffy bag and send them off to you - no charge. Just PM me your address.

I'll spend some time tomorrow going back to square one. I'm sure I have carried out the correct sequence of events but something somewhere must have moved.

I had locked the cams with Drill bits, checked the belt tension and then turned the engine over by hand before starting.

Fingers crossed nothing is bent, I commute daily on the Monster!

There are a couple of you tube vids you could take a look at to help.

It's probably worth just checking to see if you have inadvertently disturbed an electrical connection somewhere... Easily done when you're working on the bike.

Give all the connectors you can find, a good wiggle and push together, especially all the connectors to the coils and injectors ect.

Very gracious, thank you.

I purchased some the other week in readiness.

Am I right in thinking though, that if the horizontal cam is at TDC the vertical cylinders locking point will be in the right place?

That's it - there's only one point where all three pulleys line up. If it's not in the right position, the locking pins won't locate.

Note that, when it comes to tensioning the belts, you don't need to move the vertical cylinder round to TDC because the locking pin stops the valves' closing springs from affecting the tension.

Have fun!
