[QUOTE="BucKat, post: 357085, member: 29199"] kciH,,, I have read Eric's article on the KIPS valves..It does mention what CAN go wrong but not how to rectify it..Thank-you for the insight. :) jdbrusch,,,the valves do not look suspect when the head alone is taken off. Quite often I do take the governor cover and boot off to manually operate the valves.( removing the nut from the KIPS actuator arm allows free operation of the valves.). They SEEMED ok but,,,,ahhhh not so.. Even when taken out there is nearly no hard carbon deposite but there is an amount of gooo... The bores in which the valves rotate are relatively tight and are not out of round. I will check the bottom of the bore where the pin( if you will) on the valve seats. Perhaps this is out of round as the right valve pin was siezed in it's hole. The valve broke off just above this. I will also chech the valve collars for wear. Heck I'll buy new ones ...May as well. As far as oil I was running Belray H1R ( the power valve formula) last year at 32:1. This year I have swithed to Amsoil series 2000 synthetic at 50:1. I am open to all/any suggestions of course. I am entertained with the overheating theory due to the crack in the plating..It is just the plating that is cracked...No damage,that I can tell, in the actual cylinder wall. This makes very good sense. I'll look into this more...alot more. I would expect some damage to the center exhaust valve if this was the case though.It is in perfect form. I did notice that there is some wear in the governor rod on the far left threads. This would explain the stripped valve on that side. Too much play in the meshing surfaces leading to excessive wear. ...and that there are two parts available : 49046 49046-1065 ROD-GOVERNOR 1 ( - DX200EE011340) 49046B 49046-1069 ROD-GOVERNOR 1 ( DX200EE011341 - ) I need look into this aswell.
