Flywheel lock

'99 has 66k miles and I'm planning a long trip so I thought I'd replace the HES. Eurotech Motors sent me a tool to lock the flywheel along with the new sensor but I can't see any way to get it in there without moving/drilling the airbox. I think I can do it without locking the flywheel but just wondering if I'm somehow making this too hard.

Yea, you're making it too hard. Have you taken off the starter? A 6 mm allen key works as good as anything else.

I took the starter off to make sure I was in the neighborhood and that's when I discovered the REAL insertion hole was way up behind the air box. There's about 2" at most. Not enough room for the tool I have.

If you're talking about the bent bar tool, agree. Mine only fits without the trans. I typically use the plastic tooled one for lock the flywheel to swap cams but it doesn't align thinks like the bar. I also line up with the cam sprockets in the heads. I get the arrows horizontal on both heads with the cam chains in tension in the right direction (CW as you look fwd). If you pull the chains taught in the wrong direction, you're alignment will be wrong.
This is where it goes (I added the Remove Before Flight)...

I think I like the "old method" for uploading better...

That was obviously a lot of work which I appreciate but I can't make much out of the picture. Not familiar with the plastic tool, but it looks like something that engages the teeth on the flywheel would work. Is that what you are using and, if so, where can I get one?

Thinking about it, I'm not sure I've ever done it on an S. Will an allen key work? It doesn't take a huge amount of force to get the bolt a the front of the engine off, so the flywheel doesn't necessarily need to be locked in place. Can you get an impact wrench on the bolt?

I'm thinking the same thing, that is, that this can be done without locking the flywheel. Have a few things to do before I can try but that's next. Thanks for giving it your thought. Working on this bike has been a lot of uncharted territory for me. Not necessarily a bad thing.

What about etching a mark where the HES is now and putting it back in place.

yeah I use a impact to remove them
but you do have to reinstall it with a torque wrench and either lock the flywheel or
leave it in gear lock the rear wheel and deal with the spring in the drive system
you can use the timing marks to reinstall the hes

A mark would work if I was using the old one again. New one needs to be re-timed. I used a combination of broom handle and rear brake to remove and re-install the bolt. The really strange thing was the 1st installation: I could almost time it but it was at the very extreme end of the slots. After a sleepless night I decided to remove the pulley on a hunch. This is hard to describe but the Hall effect plate which is behind the pulley is not attached to the pulley and has a VERY small circular ridge to center it. The first time I put it on and even though the locating tab was right it had slipped off center. Before I installed it the second time I put some super glue between the Hall plate and the pulley. Timing is now somewhere near the center of the slots. I haven't started it yet but I'm thinking I've got it.
