Trying to remove the injectors and fuel tube on my K100 RT for a renovation but I can't get them out........followed my Clymer instructions all the way but they don't want to come out.  HELP!

They can be very stubborn, remove the clip from the top of the injector, it holds the injector to the rail. Remove the rail then work on one injector at a time. Make sure to clean around the base of each injector to prevent dirt going down the port.
I have had to put a lever under the rail at times as the O-rings virtually vulcanize themselves to the rail and head. Soaking some fuel around the base can help release them.

I've removed the clips but I can't budge either the injectors or the fuel rail.......I'll try some fuel around the injectors.

I stuck a hammer handle under the rear end of the rail and levered the end ones first.  Took a bit of force but once it was a little loose it came out very easy.

Tried that method with a bit of 2 x 1 timber and........ Off came the fuel rail nice and easy, followed shortly (after some persuasion) by the injectors which are in a poor condition, so it's off to the injector doctor for them and some TLC. I've seen a company online that charges £12.50 per injector for refurbishing which sounds reasonable compared to new ones which don't seem too available anyway.

Now for those seized exhaust nuts and studs..........wish me luck!

Use a nut splitter on the exhaust studs when they are being difficult. We have seen many a broken stud here trying to get those nuts off.

The nuts were so rusty that I drilled a small hole into them and after applying heat I used a nail punch and hammer to turn them. All of the nuts split and came off better than I expected so that was a good result. Unfortunately two of the studs are a little bent although the threads on all 8 studs are usable.....so do I go all the way whilst the engine is out and try to remove the studs or leave well alone?

That is a difficult call that one. I personally would get them out but they still can snap easily. I would make them cherry red hot and then let them cool, then give them a solid whack on the end and double nut and they will have the best chance of coming out. Here is where I insert the usual disclaimer like "it's really your call and I take no responsibility at all and if they break it's your problem" and besides I am in Australia. While the engine is out is a good time to do it. When you put new ones back in use grade 5 steel studs and put never seize on the threads and copper or brass nuts.

While the engine is on the bench I've got to try and get them out, it's not worth future hassle leaving old studs in. I'll try your method and if it all goes pear shaped I will reflect on your disclaimer. You may well be at the other side of the globe but so are my mates in Melbourne ha ha!

I got my exhaust studs out HERE

I would suggest using a bit of heat before you attempt undoing
