with stealer labor rates @ $100 hourly plus or minus all that labor to remove "stuff" makes for a costly valve adjustment!! once in there its prolly not too bad, so seeing that a 1200 cruiser is soon to be a reality i am surely interested in this!!

With 20k mile intervals, many riders will probably be on to electric bikes before they ever need a valve check.

Never say never. May come a day when petrol goes the way of the Dodo bird. Nothing lasts forever.

There is no room for the rockers to slide over. The rocker shaft and arm is removed to get to the shims. There are just two bolts holding each rocker shaft on.

Getting to the Cam Cover requires removal of the tank, coils, Immobiliser/TPMS module, spark plugs, and unbolting the coolant filler neck and re-positioning it for clearance.

Found some other interesting facts;

Valve Head Diameter
Inlet 35.60 mm
Exhaust 29.70 mm

Valve Lift
Inlet 10.3 mm
Exhaust 9.2 mm

Camshaft Timing (at 1 mm lift)
Inlet Open 5.0 ATDC
Close 41.0 ABDC
Duration 216
Exhaust Open 39.0 BBDC
Close 4.0 BTDC
Duration 215

I'd be interested to see if the cam timing is the same for the T120.
All 1200's use same cam p/n T1147025

Amen, brother! I find myself subconsciously looking for the smoothest spot in the power band, and doing whatever it takes to stay there.

Then you'll love general aviation aircraft. 100 octane leaded fuel, dual magneto ignition, two plugs per cylinder, two values per cylinder, direct dive thrust, air cooled, carbureted induction, manual fuel mixture, manual fuel primer, manual carburetor heat, throttle control cable, and cable operated control surfaces. And for adventure, get pre-war aircraft (made of wood and covered with fabric) without a engine starter (hand prop start) or electrical system.

All this fun (with better views) for about the purchase and insurance costs of a new bike.

Ride On . . .
