[oil drain pipe removal]

Right, Many thank you's for all the ideas and advice guys   Lots of cleaning, soaking and warming up eventualy got the pipes out of the spare crankcases, gsx600f ones i believe. The 650 Bandit ones were a pig. The whole one came out, eventually, by the usual methods .. The rotten one broke almost instantly. However this may have been a blessing as i was able to weld a piece of metal to what was left and use a slide hammer to pull it out .. Pretty much a whole days work but done now ..

Put a big screwdriver down the tube, and start levering it carefully in all directions. Clean the holes in the case out carefully (stuff some rag in first) use only genuine Suzuki o rings, put a dab of grease on them before fitting. And welcome. 

Thank you .. Is there any advantage th heating any of it ?

Hi all, sorry if this has been asked a thousand times but .. How on earth do you remove the oil drain pipes from the upper crankcase without destroying them ? They came out of the head fairly easily but can't budge them in either the bike or the spare cases and would really like not to have to spend 70 quid each for new ones .. Thanks in advance, might be a newby on here but not to a workshop
