This fall my 750 Paso had a failure of the output (sprocket) shaft bearing. I picked up a used bottom end and just finished transferring all of the parts from the other engine over. I hope to get the engine back into the frame today and maybe get her running tomorrow.

I may take the old engine apart to see just how much damage has been caused by the failure. From what I can see from the outside and by looking into the engine now that the pistons are out, there is very little loose metal in there.

So you've got your barrels, pistons, and heads on a new (used) bottom end and gearbox, eh Jon? Did you set new ignition timing on the new bottom end, or are you just going to see how the new one feels? Let us know how it goes.

I have found the *sweet spot* on my chain again at just on 25mm slack, and once again have a total absence of vibration.

I had to transfer the timing pickups but not the bracket. I'm hoping it's OK.

Do you have a procedure for setting the timing??

The timing should be good, jon. All you can do is align with the reference marks on the bracket - the rest is up to the igniter module.

The last time I took the timing apart, the bike felt a bit flat after I had put the motor back in. I must have slightly missaligned the marks a bit - parallax, I guess. So I took the motor out again and changed the alignment slightly. I must have got it right the second time because she ran as good as if not better than before. I could not check the advance dymanically because I didnt have a strobe light.

It might be possible to take the side casing off without removing the motor, but for some reason, I did.

How did it go, jon?

Well you can certinly take the side cover off a 906 when the engine is in the frame so cant see any differance on 750 just need a puller which is very easy to make

Nothing done yet. I was abducted to other projects around the house.

OK, jon, well I hope it FLIES. If she doesn't go as well as she did before, it can only be the timing, eh?

I'm hoping she just runs good!!

John,

check out the Haynes stuff in the download section if you want to kow how to adjust the timing.
It`s not for the Paso but the engines of Monster/SS are about the same.

Gerhard,

Glad to see you've made it over from the mail list. I still do both.

I'll download the haynes info and check it out. It would be nice to do a static timing before putting it in and having it running. Thanks.
