Read up on the procedure of measuring and adjusting valve clearance.... intake=0.1mm, exhaust=0.12mm . The bit about remove tank, crankshaft, timing hole and valve adjuster caps are understandable. Clearance of the left exhaust and L/R intake valves is "reasonably" clear, but then comes the valve clearance on the right-hand exhaust valve... doh ?

On a scale from 1 to 10 how difficult is the whole job...or at least the last bit ? What would a garage take in the UK for this job ? If I multiply that by 3 it'll give me the price in Norway

I've had spanner for two years now, and thought it about time I did it !

Cheers chaps !

It's not that bad really The point they stress about the RH exhaust is on account of the valve lifter. If you take your time and make absolutely sure you approach the timing mark from the right direction and stop spot on (as opposed to missing it slightly and rolling back for another go) You'll be fine
Out of 10 I'd say a 6 with 1 being turning the fuel on/off and 10 the removal of the gear cluster

Just to make things easier when i do mine, i remove the fairing and fuel tank - avoids any damage if a spanner slips, plus whilst those bits are off, you can have a really good clean to all the hidden bits - just take your time.

Hmmm ! 6 eh OK I'll give it a go around about February. That way, if I screw it up then I haven't ruined christmas I can always chuck her on the trailer and deliver it to the Honda dealer. Would you believe I've never had the need to turn a crankshaft before. I've shafted a crank - but she's another story ....thanks again people

When setting the valve clearance on mine I just had the valve open then rotate till its on the back of the cam and adjust. Cant see why the need to use the timing marks. No big problem to adjust.

Here we go then......I'll attemp to replace the valve guide from another thread in conjunction with this exercise. I don't understand the missus anymore , so I'll try and deepen my understanding with the Dommie. Tonight - sofly, softly....stripping - tank, fairing, loosen carb., spark plug lead. Don't you guys disappear- cos you're going to be called on very soon.....

Oh yeah !....and how do I obtain TDC......like physically what do I have to do and where do I look......and you're all thinking hmmmm! he's gonna end up with a box of bits at the honda workshop

[Rubberchicken]

TDC, you need to get both hex caps out of the left side of the crankcase.

Better polish up your cursing vocabulary, because they tend to be stuck hard. (So get a decent hex bit.)

Anyway. Big hole turns the crank, little hole is the sight hole. F mark is firing point, T is top. Something like that.

Rotate counterclockwise only, and the right hand exhaust valve has an automatic valve lifter so you may have to rotate it a bit past TDC to get the play on that one set.

(And ofcourse, there's 2 top dead centers, and only one where all the valves are closed!)

doh ?
