Hi, I have just joined this forum after something went wrong with my bike last night, i looked online and found info here about SVS
. I had a slight ticking noise, it didnt sound major at all, even a little like a lose clamp or something, I wasnt even sure it was engine related. After about 10klms/6miles something felt wrong and i limped the bike home another 3klms on 1 cylinder, when i pulled up at home the bike would still idle but there was no pressure at all from the rear cylinder out the exhaust. After reading all the info here i thought it was SVS so today i started pulling the rear cylinder apart, there did seem to be something wrong with the exhaust valves but after removing all the covers i was able to de-press the 2 exhaust valves without too much trouble so i then thought i may have had a collapsed lifter. After pulling out the 2 lifters i discovered the real problem, the bottom of the lifters have been eaten away by the camshaft lobes, I am totally 100% PI$%ED OFF about this as i had only replaced both camshafts and all 4 lifters myself about 5000klms ago!!!
I bought the bike in that condition and bought all the parts and fixed it myself, that was about 3 years ago but only about 5000k`s as i had lost my license and only got it back last week, so i changed the oil and have only ridden about 150k`s so far, not even through the 1st tank of fuel.... I havent pulled down the front cylinder yet but im expecting the same result.
How common is this fault, if at all, Im not sure if the cam lobes are ok as the lifter material is probably softer than the cam, I had a quick look with a little Single LED Light and felt the lobes which didnt look or feel too bad, should i just replace the lifters and see how i go or not??? The bike is a 1999 and has done a few klm`s but is in great condition apart from this AGAIN!!!!
