Chris79 Posted March 19, 2017 Share Posted March 19, 2017 So at end of last week i noticed a new noise coming from engine when closing throttle when revs were in mid range and above. Gave the bike a look over today and one of the clamps (think that is what they are called) that are used to bolt the down pipes to the engine has snapped. I guess that since that down pipe is now no longer held tight to the engine that is the cause of the new noise?Should be an easy fix but despite trawling internet I can not find any to buy, only a complete new down pipes set. Am I being blind or can you only get them with full down pipes set?Cheers Quote Link to comment Share on other sites More sharing options...
TimR Posted March 19, 2017 Share Posted March 19, 2017 (edited) What bike year model etc ? You should be able to get the clamps separate but some do only have them fitted to the pipes.Exhaust leaking will sound louder and can cause small popping noises on engine braking Edited March 19, 2017 by TimR Quote Link to comment Share on other sites More sharing options...
TimR Posted March 19, 2017 Share Posted March 19, 2017 http://www.cmsnl.com/yamaha-yzf600r-2000-4tv9-england-104tv-300e1_model40430/partslist/0013.html#resultsLooking at fiche looks like pipe attached if you still got thundercat as listed .Possible way round us getting the broken clamp welded or a split clamp fabricated similar to http://m.ebay.co.uk/itm/1990-2001-Kawasaki-ZZR1100D-Exhaust-Headers-Clamps-Holders-Collars-ZZR-1100-D-C-/292044144282?nav=SEARCHIf you measure the pipe diameter and stud placements i will look and see if i have a spare one i can post to you if theres a chance of it fitting Quote Link to comment Share on other sites More sharing options...
Chris79 Posted March 20, 2017 Author Share Posted March 20, 2017 Many thanks for taking the time to respond Tim and for your very kind offer to try and help me out, I really do appreciate it. I do still have the 2000 Thundercat.Having thought about it further I think perhaps I should just bite the bullet and buy some new downpipes. The existing ones are quite grotty and this may be just the first problem with them failing. I did intend to replace them at some point anyway as part of a wider strip down exercise but was hoping to have a second bike by then so I could tinker at my leisure and make a mini project of it. Inconvenient timing as always !Thanks again for your help.Chris Quote Link to comment Share on other sites More sharing options...
