ok, i've been reading that with an o-ring chain you do not need to lube it since it has sealed in lubricant. But how about where the chain meets the sproket? any thoughts?

I just put an o-ring chain on my bike, and it didn't want to flex at the point where they joined. It would click at lower speeds . I was leaving on a long tripped, and just hoped it would warm up and work itself out, which it did. I did lupe the chain out of fear before I left.

I just purchased a x ring chain after reading suggestions on here. I would think it still would need to be maintained like any chain.

Also I was playing with the air fuel mix screw and it doesn't seem like any amount of turning it in causes a lean condition - it's constantly rich with not much difference after adjustment

Technically, no it does not need lube because it is sealed. In reality, you will want to keep it clean and lubed for maximum longevity of the chain and sprockets. Only needs lube on the 'edges' though, not the middle. I use a small nylon brush with Bel-Ray chain cleaner/lube, btw.

That's strange Wisblue. Are you running rich throughout the RPM range, or do you mean at idle only? What was your current jetting again? (sorry, I forgot) If you have a pilot jet that is too large, you could turn the screw until it's ready to fall out on the ground and still be rich.

I guess I've only adjusted the screw and listened to the bike at idle. I'm running 50/165 with kuryakn aftermarket needle.

I'll have to play with it some more this week I suppose.

You should be fine with that setup. Need to adjust the screw with the engine running. Start about two turns out, start the bike (needs to be warmed up already) and turn the screw out until the idle RPM's drop, then back in 1/2 turn. Should be pretty close by doing that.

Am I correct is assuming the appropriate idle is going to "seem" fast compared to other bikes? I don't have any way of measuring it other than just by sound.

[rustygunner]

Yes, it will idle faster than a Harley if that's what you mean.

Yeah but turning it out makes it richer. So don't you mean if you have too large of a pilot jet you could turn it all the way in and still be rich?

[rustygunner]

Sorry... backwards I am. Too small pilot jet it could be falling out and still be LEAN. My bad. (slaps self, sips coffee)

I'll play with it again soon, doesn't seem to make a terrible difference turned either way....not sure what is going on with it.

And what's the deal with seafoam, I've been searching and reading about it but there seems to be as many horror stories about it's miss-use as claims it does wonders.

Yes an x ring chain still needs maintence, clean and lube, it's just that with the seals to keep the dirt out it will last longer. Why do you feel it's rich? smoke? Setting the idle a little low can help with adjusting the mixture, just set it back up when done, and yes it should ilde higher than a harley, but only a little, I wouldn't say real high. And seafoam does work but it's not miracle juice, problems uasally occur when people over do it and use too much, althou I'm not much for using it (or any other chemical) in the oil.

I'm not getting and smoke or having any other problems, most likely it's all in my head....I think it started when everyone started talking about gas mileage and I'm only getting around 38 mpg. Also it seems like the bike has a fairly low top speed compared to what others have noted on here, if i'm going 80 on the speedometer that feels about all there is. I have screwed the air/fuel mix screw every which way but not noticed much difference at all.

I'm thinking it's all in my head. Someone needs to take my little screwdriver away so I can't fiddle with it anymore.

This weekend is the chain/sprocket/brakes work I hope I'm ready.

Have you ever checked your carb slide/diapham, if it has a pinhole in the diapham or the slide is sticking it could act like this, it should do more than 80. A/F screw wouldn't affect midrange or top speed, just idle. Also try running the bike with the air cleaner element out to see if there's any difference.

Yeah I realized the midrange/top end wouldn't be affected by the air mixture screw, what was frustrating me is that I wasn't seeing any change through adjusting it.

I have not checked the diaphragm for pinholes.

Edit- I must sound like a crazy person.

Crazy in love with your bike, maybe, and that's not a crime around these parts...

(but when you hear 'tick, tick, tick', now that's a different story, I hear )

I know what your talking about. My bike doesn't seem to run a whole lot different with screw all the way in or out. But I did find the differences. I'm not sure how well you can tell with stock mufflers but mine are cut open so I can hear the little pops quite well. Basically if I have it screwed all the way in my bike pops anytime I release the clutch on decel. If I have it screwed out where it should be it only pops on a hard decel. Also easy way to tell the difference for me is startup. If I have it set where I like it the bike will usually start up and not require much warm up time. If I have the screw in too much I will need the choke to start it and keep it running. If I push the choke in too early the bike will carb fart all over the place and jerk.

But again I know what you mean. I spent a whole day once riding around trying different settings and if the bike was already warmed up it wouldn't make a whole lot difference how I had it set besides small variances in popping on decel.

Alright I was looking in the manual and there are a couple different diaphragms (accelerator valve or air cut valve) in the carb, which one would you suggest I check and replace? If I'm going to brake into the carb again (which I'm not too worried about doing) I'd like to have the part I need even if I don't need it....rather have it there that day and not need to replace it instead of open the bike up ---- close it up --- order part. Will the carb need to come completely out or can it hang such as when I replaced the jets?

Thank you! I'm not crazy!

My bike feels great in the city and up to like 50-55 on the speedo but above that there isn't much there ---- and the gas mileage sucks

[tkuligowski]

I'm guessing he's talking about the sliding diaphragm which is generally the one people are referring too when talking about possible pinholes. I've replaced all 3 of mine though when I bought the bike. I'm thinking if you just do the top one you wouldn't need to remove the carb but you would probably have to take it off the manifold to do the accelerator pump and air cut off valve.
