KATANAMANGLER Posted October 5, 2016 Posted October 5, 2016 You're half way to a 5 valve set up, keep going 3 Quote
Madb Posted October 5, 2016 Author Posted October 5, 2016 (edited) Were thinking of filling two ports and making a two valver... save buying new valves eh. Or maybe cut 1 cylinder off making a triple gsxr? Edited October 5, 2016 by Madb Spelling. !! 1 Quote
Joebloggs Posted October 5, 2016 Posted October 5, 2016 Bit of liquid metal and it'll be good as new......... 1 Quote
Madb Posted October 5, 2016 Author Posted October 5, 2016 Not quite why she went bang. Well, dint go bang as such. After my last trackday she were running good all tho i could only hit 124 mph down bently straight i suspected head gasket gone, rho no complaints as the engine had done well over 100,000 miles. Thought ok. Time for a refresh. Anyways, i rebuilt engine , new every thing, first test ride sounded lush. Pulled so much better and no flat spots. Anyways, just about run the old gal in after about 450 miles everything running lovely. As i pull out of a junction i heard a ticking noise then so as ya do flicked the kill button. Recovered bike in van and this were the result. Spark plug had no inner electrode and found one of the valve collects forged inside the valve retainer. Still dont know why she broke but hey its part of the fun, yes? Only cost i lost wes the cost off complete gasket set at £66. This happened in may this year. Quote
Madb Posted October 5, 2016 Author Posted October 5, 2016 Oh and rest of engine is fine. Even the conrod not bent. Tho before ya ask. No i havent used any parts for the new rebuild. Quote

Madb Posted October 5, 2016 Author Posted October 5, 2016 Err no. Just carbon. Added lightness! Quote

Legotoy Posted October 6, 2016 Posted October 6, 2016 What brand gasket set did you use? Just interested, maybe tolerances in that brand had something to do with it - thinner head or base gaskets for example? Quote
Madb Posted October 6, 2016 Author Posted October 6, 2016 Athena. If gaskets were different surely more than one cylinder would have been effected? And this happened 450+ miles after rebuild. Me thinking just one of those things. Quote
Madb Posted October 6, 2016 Author Posted October 6, 2016 Trying to find the valve retainer with the forged collet. Basically its sitting where the shim sits on top. Thought thats different! Quote
teltwosheds Posted October 6, 2016 Posted October 6, 2016 well I reckon it was the spark plug, seen it happen on a few 2 strokes years back. Sure glad it's not a common occurance . Quote

Madb Posted October 16, 2016 Author Posted October 16, 2016 This is the valve retainer with the forged collects . Hmmmmm. Quote
