Hey Guys, was wondering if you could take a look at this picture (attached) and tell me if this is an adjustable item. I picked up the bike for a measly $100 off eBay a while back and finally got around to fixing it up. I've put about $400 into not including what I paid for it. It's previous owners really didn't take care of it. For example, instead of changing out the impeller, they added radiator gunk which seeped into the crankcase and basically cooked on into the gear box making a real mess. Got that cleaned out. Didn't worry to much about the carb because I wanted to test if out in open desert first but noticed at high speeds it would bog down first 1/4 throttle before the engine would start to rev up again list it wasn't getting any gas. When I got it home and checked the carb, saw the throttle needle clip position all the way to the lowest setting (which would actually raise the needle up so it would seem that wouldn't deprive the engine of fuel when I turned the throttle 1/4 way) Any ideas what might be causing this first 1/4 throttle hiccup? In the picture I'm pointing the power valve actuator "lever" which has about an 1/8 in play (up and down) before anything engages. Is that normal? I know from reading on the net that the only adjustment (at least this is the only thing I could find about it) was changing the actuator spring which of course is in the crankcase, but what about this bolt I'm pointing to in the picture. I can't find anything online that says anything about making the adjustment there. Any help would be great as being old school, you'll never hear me boasting about how much I know about power valves or even 4 strokers for that matter. This is actually my first water cooled bike and I really love riding it. Easy to handle, and puts out a really good power band after a quarter throttle. Any help would be really appreciated. Other pic is of the entire bike. Getting it ready for my next ride and making some final adjustments here and there. Can't tell you how many bolts got lose after the restore job from either not using lock tight (which I was trying to avoid) or using a flat washer as opposed to a lock washer.
