harrycatcat 31 Posted April 7, 2009 Report Share Posted April 7, 2009 My lad has just bought this bike and it turns out it is low on compression should be 15 and its only 10 and needs new piston rings. Is this a big job and where is the best place or a good place to buy the rings and a gasket set. The motorbike garage is out of the question as they have quoted him "somewhere between £400 and £1000", feck that for a game of cricket. Just a thought would it be as well to put a reconditioned engine in sooner than the labour doing the rings. I don't know. Quote Link to post Share on other sites

I don't know. bandits are straight fours arent they? i have only done it on single cylinders but once you got the engine out the frame it a walk in the park tbh. but thats easier said than done with some bikes. make sure you get genuine parts and if you can get a mate who done it before to help out. my dream bike is a gsf 400 bandit only a little while til i can affordf one, good luck rob Quote Link to post Share on other sites

Crow 1 Posted April 7, 2009 Report Share Posted April 7, 2009 Assuming you have the older model, and assuming the 600 is the same as the 1200 then getting the engine out/in is pretty easy as they have a side-rail that unbolts to allow the engine easy access. I removed my engine by myself when I stripped mine down (I did strip the bike completely down) allthough I did have a hand putting it back in so that I didn't scratch my nice new shiny frame!! I'm sure two blokes could remove and replace a 600 engine with no trouble at all, in fact I'm willing to bet that the hardest part will be getting the airbox rubbers fitted correctly! As to whether or not its easier to get a recon engine then I suppose that all depends on your mechanical ability! If it were me and I knew the engine I had was OK apart from the low compression then I'd probably fix that! Crow Quote Link to post Share on other sites
droid 11 Posted April 8, 2009 Report Share Posted April 8, 2009 I agree with Crow (amazingly) Trouble with putting a s/h engine in, you don't know the history, and you might be substituting one problem for another. A reconditioned engine won't be any cheaper than the bike shop quote, though you'll have a shedload of spares from the old one. If the engine's otherwise sound then do the rings. Check the bores though. if they are worn then that's a whole different ball game. Quote Link to post Share on other sites
harrycatcat 31 Posted April 8, 2009 Author Report Share Posted April 8, 2009 Thanks for the responses especially Crow's. It is an older bike and my sons mate who is a motor mechanic although he is only 23 says that he will help/do it and is looking forward to it. So it looks like new piston rings is the answer. Thanks again. Quote Link to post Share on other sites
