Can anyone give me a number for someone who can rebuild a crankshaft for a Suzuki gt550, Somerset would be ideal, but I guess thats a long shot. Thanks in anticipation. Rod

I have several GT550s but never needed a crank doing. How do you know yours is U/S?
Chris Applebee seems to be the known name for the job.

Not 100% sure if it does need a rebuild, but its an engine thats been run on premix with no oil pump, so I guess the bearings will be knackered. Having said that whether its true or not, that there is a mod to allow full lubrication without the oil pump. Just signed up to the kettle klinic, tons of useful stuff on there.

Bandit 600? I didn't realise you was that old!!  Shocked
You sure you're not Dick Turpin?  Laughing

If it's been run on premix without doing something with the oil slingers on the crank itself, it'll certainly have a shortened life. I dunno why people insist on running these engines on premix when they are designed for positive lube to the bearings. The Yams were different as the autolube only fed into the inlet so it was really premix without getting oil in the carbs.

Hi Alan H, you mentioned crank oil sllngers on one of my posts I think - do you have a diagram or something of what you mean? I've mentioned this to people with far more knowledge than me and they hadnt heard of the term. Even the guy who just rebuilt my engine! My X7 is on premix with new/better bits in so it would be nice to keep it alive as long as poss! Especially as its tuned!
Would squirting some 2T oil into the crankcase under the pistons every now and then help!? Just then annoy the neighbours with a smokey start up!
