125-200cc power valve clean wre 125

ok, this seems a bad design but the powervalves are at the front of the cylinder, with the frame barely an inch in front of that housing plate that covers them,. The housing is held on by four little bolts. I can unscrew one of them with a spanner but the others you need an allen key to turn, but, you cannot GET one in there because the frame is in the way! On the left hand side of the housing there are two holes one above the other, with rubber hoses attached. My powervalve was sticking open halfway so I took the hoses off and sprayed a lube spray in both holes, then did the same to the powevalve motor and cables and into the other end where the cables attach and physically turn the powervalve. Took bike today and it seems fine again, but I can't believe you're supposed to clean them by spraying stuff in the holes, I'd assume you'd take the housing off and clean them properly, get rid of all the goo! Do you really have to take the plug, hoses, cylinder off JUST to get at the housing to clean the valves???

You can take out all the engine mounting bolts and rotate the whole thing on the swing arm pivot enough to get the cover off. Still a pain.
