Cheers for that.
There is a tyre shop about 80 meters from where i am staying, so i think it will pay for me to push it over there and borrow his airgun.
We also have a full workshop (power station) in work, and a decent set of pullers which can be modified/ added to.
I've never realy worked on a bike engine before ( i have the mechanical skills and tools (i'm a mechanical fitter by trade). From what i've read is this the basic way forwrd to replace the cam chain
1* cup of coffee and roll up
2* remove seat, tank, carbs, rocker cover, crank case cover, drain oil
3* get friendly tyre fitter to remove rotor bolt
4* using correct puller remove rotor
5* set engine to timing marks
6* remove cam chain adjuster
7* remove cam
8* remove cam chain
9* remove guides
10* replace guides and chain
11* refit cam/chain to timing marks
12* refit chain adjuster
13* rotate engine by hand to check timing marks
14* refit rotor
15* check valve clearances while i'm there
16* refit covers/carbs, tank and seat etc
17* refil oil
18* cross fingers and start engine
19* if all is well celebrate with

and cigaretts
If i've missed anything obvious, or its all wrong, please let me know. I realy don't want to mess this up

:confused1:
Cheers
