Broken tappet

A torque bar will not stop you rounding off nut's and bolt's. It will only stop you over tightening them and shearing them off. When replacing bolt's always apply copper grease, but NOT to internal engine parts.

my only advice with sockets is make sure you buy 6 sided ones,

I borrowed some of them star type ( 12 sided say ) and found they just don't grip.

also impact driver has been a god send

....read somwehere that copper grease shouldn't be used where steel bolts are inserted into alloy threads as it increases chem reaction between alloy and steel and thus increases seizability.... some other kind of grase was recommended for these situuations (cant remember what though)... but maybe that was a load of crap ?

I think I would use something other than copper grease for engine mounts having had the last ones I worked on sieze up so solid that I had to gas axe them out after a year of riding when I came back to removing a copper slipped bolt. At the trail biking place I did some work at they used a mix of waterproof grease and acf50. Copper grease is good where there is heat and steel on steel but that combo of salt water off the front wheel, alloy, steel and electric from earthing the starter - something in that mix was bad.

I was talking about engine bolts lads. I will start stripping my mates z650b1 engine tomorrow which i built in 1995. I am confident that i will not have any problems getting any casing bolts out seeing i applied copper grease when i built it nearly 19 years ago. I will let you know.

Hi,
      Molybdenum ( dfsm) anti seize grease is a better alternative to copper-slip, and it will take the heat as well, but it is more costly, used it for years in industry without problems, one trade name is rocol, as for torque wrenches, its worth considering "facom" if you find one at a reasonal price

Thanks for all the help so far, interesting info regarding grease, also, I'm thinking about getting Halfords Pro Torque wrench 8-60 Nm seems to cover all the range on my bike.
Is this tool any good? at £74.99 should be OK I hope.

Any recommendation in up to £100 price range?

hi Bomber I've got one and am happy with it.  Bought it last year to replace the  hopeless machinemart one I had

[MIKE550/4]

also bought one and no problem so far

[bomber]

A bit of an update,
Got my torque wrench from Hallfords for just over £50! I convinced store manager that I'm ehmmm mechanic and he gave me a trade discount card! very happy, bought few other bits and saved about 25% on most items!!!
Now, bad news, 3 screws which holds cover where snapped...
Not sure what to do, to do proper job I should take cylinder block a part and take broken bits out.
I'm kind of tempted to ignore it until end of summer, I'm a bit of scared what type of other issues I will find once the top end is off, plus never done it before.

Do you have replacement tapper screws Bomber? If not I'll throw a couple in with the seat.

[bomber]

Thanks, i got them a while back.
I'm after tach gear cap...

I was lucky enough to find one on Ebay a while back for £20. I couldn't believe it.

[bomber]

how about this?

[bomber]

Tappets look alright, but head has to come off, thinking about it really should fix it properly a specially that there is a oil leak from gasket.
This is such a disaster project, happy that temperature is getting higher so easier to work on bike.

Mike, I did send bomber a PM explaining everything he was getting in a bit of a mess. bomber, once you get your rocker off, check all your tappets for any chips. If you find any that are chipped, check all the valves for any damage.
