Today I finally got to remove the buckets from the intake valves and see what sizes are in there so I can get the correct replacements.
1a =2.75, 1b = 2.70, 2a = 2.75, 2b = 2.75, 3a = 2.75, 3b = 2.70, 4a = 2.75, 4b = 2.80
the measures valve clearances for the largest size that WILL go under the gap between the bucket and the cam shaft are
1a = 0.10, 1b = 0.10, 2a = 0.13, 2b = .15, 3a = 0.15, 3b= 0.15, 4a = 0.13, 4a = 0.13
So my math gives me the following buckets I need to buy to get all the intake valves into the higher end of spec
1a = 2.65, 1b = 2.60, 2a = 2.70, 2b = 2.70, 3a = 2.70, 3b, 2.65, 4a = 2.70, 4b = 2.75
Agree? Disagree?
I have heard some people say it is ok to reuse an existing bucket on a different valve and others say it is not. It would only save me 3 buckets so I am not that bothered either way but what is the general consensus?
Also I found one minor issue when I put everything back together again (it is going to be at least two weeeks before the new buckets get here and I did not want to leave all the guts of the engine open until then)

As you can see it is slightly misaligned compared to before.
I think that is because the camshaft was put back in a slightly different position? I am not planning on riding the bike before replacing the buckets so I have to disassemble everything again anyway but I assume it is very important I get the camshaft back in exactly the same place it was before I took it off last time?
