I haven't reused head gasket in the past but wondering what you guys thought of reusing one?
Its metal oem yamaha with about 400 miles on it.
This head gasket just got unlucky on this bike and had a crappy life.

Air cooled lowish compression.

You can reuse them and get lucky and you can re-use them and not. If it's been running in a bike them generally they're done in. Up to you...

With all the trouble you had - Get a new one for sure.

I agree, replace it. It has been compressed once, will not compress more. Probably leak.... or not.... :funmeterno:

Any thoughts? I need both gaskets.

Is that the same bolt pattern as your head ? Looks like it in your first photos, If so they'll work fine.

When putting the clutch assembly back in. Do I need the tool to hold clutch to torque down nut? Or can I use....
I don't have any old plates to make a tool with. Wondering if their was a way around this.

Get the tool. Its £20. There are other ways of jamming up the clutch basket but they often end up doing damage.

Bought the tool at Cycle Gear (US motorcycle parts/gear store) for $21.
Took it off with air tool but figured it should be torqued down right for return.

[QUOTE=jjrider;537064]Here's where I put my probe in my XT's , This location measure the oil temp right above the right side exhuast valve , the hottest part of the motor and it'll show the quickest if anything is going wrong . I just see what it reads normally and if it suddenly goes higher I'll know to check things out .

How did you attach the sensor bolt? I have no hole threaded or not there.
The sensor bolt is the same length as some rocker cover M6 bolts. But the sensor bolt is not threaded long enough to hit female thread.
Am I thinking this correct?

I drill that hole in the heads then tap for 6mm x 1.0 . As they are stock there's an aluminum plug there and the hole in the casting is around 3/8" diameter behind the plug so the temp probe reaches in to where the oil is being splashed around . You can't use these probes as a replacement for any bolt , they're not made for it and will break before torqued down to the amount a bolt should be .

If you don't want to drill the hole in that plug you can drill & tap a hole in the rear valve inspection port and put the probe there , it will be exposed to the oil up there but won't read quite as high or as fast as the other spot . Will still be plenty good and the cap can be cheaply replaced or a short 6mm bolt put in the hole if the probe is removed and not used anymore or swapping to another bike.
