Its very time consuming, the bike was in bits for 2 weeks as i ordered the shims i needed, and broke a cam cover bolt, oops!
Putting it back together was the pain, mounting the radiator and the hoses, ect.
If i spent every day after work doing it though, i could of done it in a few days, I was in no rush though, i haven't got my full license yet
Not sure i would be comfortable doing it on someone elses pride and joy just yet. I'd have to do it a few more times on my own, as this was my first time. Its pretty easy to do, i could give you some pointers as you follow that guide, if you want to try it.
Agree with the sydney city statement, they are terrible. scratched my swingarm when they changed tyres, claimed they cleaned out the carbs but the bike ran worse..
