Ok so ive a really grotty connector block under the tank which is so trempremental its safer to take apart and completely replace it. Which is the better method to go with? Just using bullets or is the a good connector block to replace it with? Its tge 2x3 block that does lights and indicators.

mate, use crimp heat shrink connectors for each wire....proper job

Why do you need a connector block there in the first place.
It's only for the manufacturere convenience that they have so many connectors on the bike. Think of all the problems that we get because of connectors. I have cut the connector block off my Reg / Rectifier and solid soldered the wires (using a reg with a bout 300mm tail potted into itself), just so that I don't have a problem there.
If the bike was mine and you have a problem with connectors underneath the tank which are difficult to get at then consider this as an option.
Can you consider why you would need to have a joint at that point?

Just my ten pence worth.

Oh and for information, my Ten was the very first to rear it's ugly head and have the reg / rectifier coinnector problem. Not any more.

I have been giving this lots of thought, becuase i've been working so much i've not had chance to fix it so had more time to plan.

I initialliy thought a block for ease of maintanence then as i thought about it you don't ever touch that block unless replacing the "dash".

I've 2 options for connectors, i've grabbed a load of uninsulated pin connectors from work and heat shrink, or good old halfords bullet connectors. but i'm thinking it'll be a better job using the uninsulated pins as i can waterproof them better.
