And all of the production cylinders are the same height. The '88+ HRC jug is slightly taller, which will lower compression with anything but the HRC piston. Head bolts and dowels got larger in '88 so heads and cylinders cannot be mixed and matched without mods or fabrication.

When fastening down the cylinder head cover, when should the 8mm bolt be torqued down?

After the 6mm bolts have all been tightened in the approved 'diagonally opposite' manner; first, before the 6mm bolts are tightened; or at the same time as part of that process?

Thanks

The XT600 is a Yamaha.

There are quite a few XL600 CDI units on ebay, rather than using a Yamahaha unit that may or may not work.....

yea got an eightie three cdi with the round plug so need to work out what wire goes where as the pin position seems to differ from 85,86 cdi with the square dual plug layout.

I was merely poking fun at what I thought was a typo. R and T are next to each other on a QWERTY keyboard, after all. And I do like Yamahas, actually...and Suzukis. I tolerate Kawasakis.

As far as using the XT CDI, if possible, I would compare pulse generator and stator winding resistance between XT and XL600s and see if the ignition timing specs are fairly similar.

Hoped the damaged thread of one of the 6mm head cover bolt holes that stopped thebolt from being torqued down properly wouldn't cause an oil leak.

I can hear the guffaws from here.

At least on my RM I can pull the cover without dropping the engine. But, of course, the damaged hole is too close to the frame to be able get a drill at it to install a helicoil. And in any case, the idea of producing swarf in that area around assembled valvegear doesn't rest too easily.

So unless someone has a better idea, it looks like a head-off job.

Less than 50 miles since the engine went together with new head and head cover gaskets, both OE. What do people think about reusing them?

Thanks

The rocker cover can be reused with the help of a sealant like Hondabond on both sides of the gasket. No go for the head gasket.

A couple of weeks ago I worked on a fellas XR650 for broken rocker cover bolts. Of course they were the ones right by the spark plug. At least the head came off without having to pull the engine. Heli coils to the rescue.

If the head gasket doesn't lose the black coating in disassembly(or never had any), I would consider reusing it...
