For those of you who have performed "Dave's Carb Mods" on your XR-L, have any of you had any problems at all related to them? I've done a good bit of searching and haven't read anything negative yet, but thought I'd ask - just in case. I recently picked up a '93 XR650-L and have been reading all the glowing comments regarding "Dave's Carb Mods". The previous owner had put an old external disc Supertrapp pipe on there (currently with only 5 discs in) and says he rejetted for it - but I don't know what size jets are in there. The smog pump is already gone and the airbox snorkle removed, but the stock air filter was in there. I've replaced that with a Uni foam filter. Sounds like all that's left for me to do is drill the slide, shim the needle and check the jetting.
