My first guess is a lean idle condition. This causes a "hanging idle" which means the bike won't settle down to idle properly. Try setting the idle mixture screw so it's way too rich and readjust the idle. If the problem improves then you need a larger idle jet. This could also be caused by a cracked or leaking intake manifold boot.

The only part that doesn't make since is you say it only happens when the bike's moving. I'm kind of lost there. Try the lean idle thing first.

Will do. I appreciate the advise. I'm supposed to be off work tomorrow so me and some friends can do about 100 miles off road. I may be working on my bike instead. I will sleep on it and maybe something will come to me by morning. I will post back when I fix this problem.

I bought a '77 XT500 w/660 original miles about two months ago for $400 and spent another $250 to make it roadworthy. Have been having a ball with it, now have nearly 1500 miles on it.

I haven't done extensive searching, but did find this 3.5 gal. tank at Clarke Mfg.: http://www.clarkemfg.com/cart/index....roducts_id=261

I plan to make my own mounting brackets and use a pair of these as saddlebags: http://www.northerntool.com/webapp/w...3124_200153124

New to the site

Hey everyone. I'm new to the site so please forgive me if I'm not following correct protocol. I have a 2005 XT 660 R that I am interested in selling. It was purchased in Holland brand new and came back to the US along with furniture in a sea container. (thanks USMC) It is legally now titled in the US. It is in excellent shape and has 13,890 Kilometers.

Any interest out there???

If you have one, I recommend your garage. If not, your dining room table.

Well, what are you rebuilding and what's the problem with it? Forks are easy to rebuild.

Shocks aren't bad either, but most manufacturers don't publish rebuild instructions for shocks and often don't sell rebuild parts either, so that can be a bit more tricky.

i guess i should have said they're the rear shocks. forks i've done, but not shocks.

Starting Troubles

Hey guys,

My recently acquired 78 XT500 beast doesn't want to start anymore. Being new to the whole motorcycling thing I am pretty clueless as to what to do. I charged the battery, so that when the key is turned to the right the taillight is on (even after removing the key). Turning the key to the left and kicking is getting me nowhere as is turning the key to right and kicking (just for good measure). Any suggestions as to what to do next? Thanks guys.

Hello, I would go through the usual routine of: take out the spark plug. Then put the plug back in the boot and lay it against the cylinder head to ground it. Turn the key to the right and kick the bike and make sure you have a big, fat, blue spark. Make sure the plug is not sooty and fouled as well. If the plug looks good and you have spark, put the plug back in. Make sure you have fuel in the bike and you have the gas turned on. Kick the bike over. My opinion is if it don't start in 5 or 6 kicks, stop trying because something is not right. Then go to the points. Make sure they are clean at the point where they contact each other. Make sure when the gap is at it widest point, the gap is .014. This sounds elementary but your post said you are new to motorcycling. You need fuel, spark and compression to make an engine run. There could be other things to check later like timing and valve adjustment. If it has been running lately and suddenly just won't start its either the lack of fuel, the points or a fouled plug.

Hope this helps.

Steve

Thanks for the reply Steve. I will try the plug suggestion to rule out the spark part of the equation tomorrow. It was running a couple of days ago, the guy who I bought the bike from said he had adjusted the valves and timing before selling it to me. Just downloaded a manual so now I will have something to go off of. Thanks again!
