  1. I've purchased an OEM 40T rear drive sprocket. Now I need to get a front sprocket, but I wanted to ask you guys some questions before I do.. just so I can learn a bit. Are there certain size sprocket combinations that are required? Like 16/40? Or can I use a different front sprocket with a 40 tooth back sprocket. What will give me better mpg, or lower RPMs at higher speeds? I'm getting confused with this stuff Thanks!
  2. Whatever happened to a good ol' paper map? Or hell.. save money and just stop at a gas station and ask directions the whole way. Much more adventure, meet more people, excuse for a smoke, etc...
  3. You had to pump the oil yourself on those, didn't ya?

    I'm guessing you did this at the same spot, on a flat, in the same gear, with low or no wind..? I think your guy at work is probably correct, assuming you did the aforementioned. I've never installed a PC.. but I don't see why it couldn't be installed "inside" the fairing.

    Placebo effect? If you could trace the wire and tell us where it leads, it might give us a better idea. Maybe a picture or two if you don't know what the "thing" the lead goes into is called.
  6. Awesome! Thanks for the link. I don't know how I missed those guys with hours of scouring the internet for parts. I'm currently trying to haggle a guy for a digital copy of the service manual.. Hopefully I get it before I tear into the engine I'm planning on pulling the engine out anyway, to clean the frame, and to change/clean the sump and strainer (hopefully I can find them) I found a picture of that gasket section I was referring to (that I think it leaking), Jim: http://www.plenternz.com/images/371-00000-95.jpg Is the rubber piece you are referring to in there?
  7. Currently, if I push down on the starter chain where it runs parallel to itself, I can get the chain to touch itself. This, I'm guessing, is too loose (I do hear loud noises occasionally when starting the bike electrically).. correct? When you say movement, you are referring to the chain's ability to move up/down, right? Thanks for your patience, Jim
  8. Jim: When you say "couple mm of delfection", I can't grasp the meaning. By deflection, do you mean some kind of deviation(pulling/pushing the chain up/down) from its, I'm guessing, somewhat taught position? How full is a "full engine service"? What I'm saying is I've searched for gaskets for this bike, and they are extremely hard to find, and extremely expensive when I hardly do find them, which puts me in question of how far down into the engine I should go. There is a leak on the left side which I plan on fixing, but it doesn't seem to be too hard of a fix. If you navigate here: http://www.partforyamaha.com/pages/parts/v...d/2/Yamaha.aspx and look up a 1973 TX500, and select the "CYLINDER HEAD - CYLINDER" the gasket that looks like it is leaking it number 2 - labeled "GASKET, HEAD COVER 2" Could I make this particular gasket? Also, the oil filter is ridiculously hard to find and Yamaha doesn't make 'em anymore, I hear. What kind of solution do I have for this situation? Thanks so much for sharing the wisdom
  9. Thanks for the welcome drewps! I'll be PMing yamagod here shortly
  10. Thanks Jim! I read somewhere that they were referred to as XS500's.. but when searching for XS500, I didn't see the same year anywhere. I saw, if I remember correctly, 1976 and on. Are you implying that the 1976 xs500, or any xs500, has the same engine, therefore same manual? I only drove the bugger about 10 miles, and I didn't really notice the oil light doing anything strange while riding it. I didn't want to put too many miles on it, for fear of the tapping noise in the engine, and the oil had the smell of gas in it. I haven't removed the crankcase cover, only the left side (if sitting on the bike) cover, with the stator and starter chain/gears. Is there anything particular I should look for in the engine to see if it's worn/broke? Also, I'm really confused over the tension of chains (i.e. cam chain, starter chain, etc). How tight should they be? Is there a rule of thumb to go by? Any advice would be greatly appreciated! Thanks for the help, Jim!
  11. Hey guys, First off, nice to meet you all. (as far as meeting on a forum goes...) I'm new here. Just got one of my first bikes.. a 1973 TX500 Got the carbs off, and cleaning. Primary cover is off for general inspection/cleaning. I'll have some picture for you guys soon enough. Anyway.. I've been scouring the internet for a service manual for this thing (there is a loud tapping going on in the engine, and I'm guessing it's either valves or the cam chain slapping around... anyone know how I can figure out which it is?). I've never tightened a cam chain, or done a valve job. Hell I've never taken off a primary casing. Having tons of fun, but I need a reference manual for this toy. I'm a college kid with no need to spend any more money on this thing.. I've seen hundreds of service manuals in PDF formats floating around, but cannot come up with one for the TX500. Anyone got a link, or the file you could email me? Thanks for your time!
