zita79 Posted September 30, 2011 Posted September 30, 2011 I picked up a 76 XS 500 a while ago and I finally have it to the point where I'm trying to get it running. The previous owner took everything apart to "clean it" and I don't think he really new what he was doing! To get to the point, it appears that everything was removed under the points cover and put back on carelessly. I can't get it to fire up but it almost seems that it's 180 off, if that makes sense. The info I can find is very limited and I can’t find a shop manual for it. My question is where do I set the main plate to? After the plate is set, where do I adjust the right point plate to - there are a few "dots" and some marks on the right point plate, and the left point is mounted to the main plate. After the plates are set, do I gap the points with the timing mark at the "F" position for the corresponding cylinder? I can upload some pics if needed. Thanks for the help!
up.yours Posted October 2, 2011 Posted October 2, 2011 it's been a long time since i had one of these tempermental swines, i can't remember for the life of me how i used to set them , but once you suss it, wright it down and take photos, because you will be doing it regular.
Moderator drewpy Posted October 2, 2011 Moderator Posted October 2, 2011 put the plate where the adjustment notches are. adjust the points gap first then set the crank to LF mark (take out the plugs, its easier) the left points should be just about to open when the LF comes on the mark. same for RF make sure there's no sparking across the points when its cranked over as that means the condensor is shot. finally strobe the whole thing when the engine is running. If you can't do all this you need to get a manual and read up or get someone else to do it as its pretty straight forward engineering.

Moderator Airhead Posted October 2, 2011 Moderator Posted October 2, 2011 Nope !! XS500's are a bit different well thats a great help Jim
triton john Posted October 2, 2011 Posted October 2, 2011 Put a Bransden on it and forget all the grief that comes with points. For a fit and forget bit of kit the Bransden takes some beating and for the money well worth it.
up.yours Posted October 2, 2011 Posted October 2, 2011 good idea, mine was a real pain in the arse from what i remember. every other month it needed reseting, but when there running they are nice bikes.
zita79 Posted October 7, 2011 Author Posted October 7, 2011 Thanks everyone for the feed back. This is my first Yam and its a lot different than the Honda's and Kaw's I've had in the past! My goal is to make a Cafe Racer out of this one (another first!) but I wanted to get it running and see how the bike feels before I set down that path.

Kjetil Posted November 23, 2011 Posted November 23, 2011 Hi This is my first post here. Regarding the Brandsen, where can i find one type that fits the XS500?

Kjetil Posted November 24, 2011 Posted November 24, 2011 http://www.motorcycl...ycle_ei_kit.htm Thanks, but they are out of stock.
berniebee Posted December 8, 2011 Posted December 8, 2011 And they probably will be out of stock -forever. Welcome to the world of XS500 parts. The X is for eXtra hard to find. Seriously, many stores show XS500 parts as "out of stock" when they have no intention of restocking or they've never stocked them in the first place! Let me know if you have resolved the points issue. One thing that immediately comes to mind is that when the points baseplate is reinstalled, the "T" mark on it should align with the pointer just above the base plate , the pointer being held down with a (usually ) painted screw. Unfortunately the DPO (dreaded previous owner.) may have removed the screw and disturbed the pointer alignment. All subsequent points adjustment will be off. So now what? You have to realign the pointer, preferably with a dial gauge set up in the spark plug hole which will allow you to find TDC. however, I've done this this a wooden dowel,(watch it go up and down through the spark plug hole as you turn the crankshaft.) it will get you in the ballpark. Let me know if I can be of further help.
