CRF80 manual help, please

[BM-GS]

Hi all,

Just got a CRF80 off TM for #1 son. It seems in (mostly) good nick, but it's at least 3rd-hand and there's no manual with it.

Can anyone please tell me the correct torque values for the common things like:
axles f & r
oil drain-plug
steering head

Also the oil capacity (which I've roughed out at about 850ml).

And the chain slack for when I get a new one, so I don't root that.

Ta,

Shouldn't really need to torque them, just do them tight enough that they wont come undone, but not so tight that they'll strip or thread.

as for the chain i believe it should be 2mm or might be 2 inches. from the swing arm (??)
correct me if I'm wrong.

anyway, it should be tight enough that its not hitting the swing arm but not extremely tight

You're wrong.

You need to torque certain things, or do you just tighten your triple clamp bolts up until you squash the fork tubes?

I plan to torque everything, it's just a matter of how much...

On which topic, how accurate are torque wrenches, and how often do they need calibration? Assume that it's usually left unwound (ie: at its lowest torque setting) in a garage at approx outside ambient temp/humidity. Used about every 2-3 months.

Maybe this might work?

Not such a problem on conventional forks....

You'd have to be a complete muppet to tighten them that much...

Hi all,

Is this not stamped on the crank case somewhere?

Pretty easy to do on road bikes with upside down forks if your running 30mm cartridges. Specialy if you have aftermarket triple clamps or clip ons.

We torque everything on the race bike but I wouldnt bother on a farm bike but if you can be bothered it is good practice

Sadly not. Roadbike has a little plaque with quick-change, filter-change and rebuild quantities on. Maybe some newfangled KTM will have a mummy's note on the side...

I'll write it on my sauce bottle when I find out how much goes in.

Odd for a Honda, the missus's CRF150 has it. The flash harry KTM has lots of cool info stamped on it, like the triple clamp torque values and such...but not the oil quantity. Which is why when I started it up after one oil change, I thought it sounded a bit more noisy than usual... then remembered it was my old RM that took 700ml of oil. So I added the remaining 400ml that should have been in there and she was all quiet again...

Edit: Ha ha, just figured out who you are (admittedly not that hard, but I don't pay much attention to things like details...) Going to buy a KDX soon then?

Thank you, thank you for that link - GOLD! All the Honda on-road & off-road bike manuals are in there, plus... well, all Honda product Owners Manuals are there, usually one for each year. Or here: http://www.hondampe.com.au/repositor...s-manuals.aspx

That deserves a sticky all to itself! I bet it's so useful that they take it down soon....

I might be. Just got to sort details about how to get it (and the other bikes) to/from places. A bit put off by the 2T oil on all my gear now. A 4T might be better for duffing about after the boys, though they are definitely getting faster - #2 son needs to be onto the 70 ASAP, cos the 50 can't keep up with him!
