thundercat2325 Posted June 25, 2007 Share Posted June 25, 2007 Hey there all,I''ve been looking for an engine to replace my yzf600(98) thundercat for a while, been doing some more ringing around and i've been told that it might not be blown bottom ends after all, it might be camshft tentioner, can anyone help on this as to weather there is a way of looking and telling the diferance or what this sounds like compared to bottom ends ect. at moe my poor baby sounds like a bag of big heavy nails is shaking around the bottom of the her engine. I can't get her into gear but she does start. If anyone can help....or have any ideas....Thanks guys x x x Link to comment Share on other sites More sharing options...
chrisw Posted June 25, 2007 Share Posted June 25, 2007 I suppose the obvious thing is to have the camchain/tensioner checked. You could buy a Haynes manual and have a look yourself, but if you're not cinfident in doing so ask a garage to take a look, explain carefully what you think may be the problem and don't let them start replacing things unti you've given them the go ahead to do so.

thundercat2325 Posted June 26, 2007 Author Share Posted June 26, 2007 I've had a ring around garages asking how much just to diagnose the problem and i've been quoted 500-700 quid and thats not even replacing any thing, the only problem with that is if it turns out to be the bottom ends and other problems i'm looking at a huge bill. the 500-700 quid for diagnosing could be spent on a new engine but the brick wall i face is finding one. I'd love to have a go at fixing/helping someone fix her but i just dont have anyone i know to do that with me so if anyone lives in surrey and is good with engines and doesn't mind showin me how to work on a bike message me (i will pay of corse) Link to comment Share on other sites More sharing options...
harry69koi Posted June 26, 2007 Share Posted June 26, 2007 Cam tensioner would make a rattle on idle that would slightly go away when a few revs are applied Without seeing ur bike m8ty i would say the big end bearings are shot or sommat has come addrift in the gearbox with you saying you cant engage gear? Be cheaper and quicker to whack another lump in it imho Lee Link to comment Share on other sites More sharing options...
chrisw Posted June 26, 2007 Share Posted June 26, 2007 Quotes of that price are outrageous, crike you're only asking them to have a look at it. A good garage would be able to diagnose something fairly quickly. Link to comment Share on other sites More sharing options...
martin young Posted June 27, 2007 Share Posted June 27, 2007 If it won't go into gear it could be broken clutch plates or basket, or even worn out shift drum or worn or broken shift forks. Clutch is fairly simple to check. Obviously without hearing it it's very difficult to suggest what it could be. Link to comment Share on other sites More sharing options...
