What are the engine head torque specs for 1986 Yamaha XT-600?

SOURCE: Need cylinder and cylinder head torque specifications 98 XR 250

you dont need torque specs on that just use a 1/2 inch drive with you 14mm or16mm socket hold the wratchet right at the top and tighten it as tight as you could get it like that then use wratchet in normal position and just give it a little snugg it will be perfect i have done it a million time on the same type of bikes...

SOURCE: 87 samurai bolt torque specs for engine

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.

The factory service manual is the only way to go.

Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)

Intake & exhuast manifolds- 13.5 - 20 lbs

Flywheel - 41.5 - 47 lbs

Clutch cover - 13.5 - 20 lbs

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

1. 20 Nm (15 lb-ft).

1. 40 Nm (30 lb-ft).

1. 50 Nm (37 lb-ft)

• Tighten to 40-50 Nm (30-37 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.

• Tighten to 20-30 Nm (15-22 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.

SOURCE: i can not find maintenance manual for YAMAHA XT 600 E

There is an XT 600E repair manual listed at this site. It appears to be in German. The Clymer manual covering '83-'89 is the latest from them. Haynes never made one for that model.
