I've always trusted to the scottoiler which was already fitted to my bike when I bought it. Some people swear by them, but I'm not particularly impressed.
I've found it difficult to regulate the oil flow. If you don't use enough the scottoil leaves a gungy residue which seems to attract grit and dust and make a "lovely" abrasive paste. If you use too much the throw off from the chain covers the engine and sprocket covers, the swingarm, the left hand side of the wheel. Then when you've got it about right the temperature changes, the viscosity of the oil changes and you start all over again. And too little or too much? Either way you end up doing a lot of cleaning, and it doesn't lubricate the side plates so you have to clean and lube the thing manually to stop rust anyway. Neither do I seem to have enjoyed the spectacular chain life that some people reckon they get with a scottoiler (some people talk about 25 thousand miles).
So, unless anyone has a better idea I'll switch the scottoiler off and try Shazaam's 'WD40 before each ride' trick on my new zero miles chain.
