XR and XL 250 has a camshaft decompressor, and the modern RFVC 250's also have a manual decompressor. This lever has a cable which goes up to the lever on the head, which in turn opens the exhaust valve slightly. There is a concentric lobe that is actuated by the kicker for the first few inches of the kick, this lobe pushes a lever, which is mounted externally on the right engine case. XR 200 runs a kickstart actuated decompressor. The XR 200 and the XR 250 (or XL) are COMPLETELY different models. all of which can be accesed fron the side w/o splitting the case ( or is that how your shop makes its money?) there are three gears, the kickstarter, the idler, and the clutch gear. You only have to remove the clutch cover. i was merely debating the reason you stated for the decompression systemĪlso if you work on so many bikes why do you think a kickstarter gear replacement requires a case split. the weak gears may very well be true but. I still cannot believe that the decompression release was designed to make up for weak gears. The gears may indeed be weak, but I doubt that honda ( or any other manufacturer) would spend so much time and $ to fix a pronlem that could simply be resolved by three new gears. then also retool the kickstarter shaft for the lobe assembly, etc. It costs so much more to retool the case half to accept the release mechanism, then retool the head to accept the anm that depresses the rocker arm.
And from a prodiction cost standpoint it doesn't make sense that if you discover that a gear is weak not to just fix the gear. I have never heard of this problem before. nevertheless, don't get so touchy, I wasn't doubting your knowledge, just expressing that i am very active in the sport and have done all my work to all of my, and countless others bikes. Is the 200 the same as the 250? I assumed it was due to the habbit of most manufacturers to keep production costs down and use the same parts is several models. I also work on many bikes, although i'm sure not as many as you, but my lobe was left in. I'll bet an xr that you have typo's and errors as well. I'll be watching your posts for spelling and grammer. As far as the spelling goes, it is more a product of being in a rush.
