Does anyone know of a suitable valve spring compressor that's good enough to get these valves out, i'd hate to think how much a genuine Yamaha one will cost from the dealers? what about a D.I.Y one? have tried an automobile one from Halfords and found it to be useless so took it straight back for a refund. Also, what about a Flywheel puller? Again is that a specialist one from a dealer? This engine stripdown is going to be expensive enough without extra cost to have to buy specialist tools from Yamaha... Any advice or tips guys, bearing in mind i'm in the U.K so dealers in the U.S. would be a bit long to wait on delivery etc, pity tho, as prices here in "Ol' Blighty" are rather more expensive than what you lucky so-n-so's have to pay..
