Hey guys, have a 77D and looking for a tachometer replacement, since apparently i can't take the cover off and replace the missing screws. I can take the set off your hands to avoid breaking it up, if necessary. Thanks, James This is my version, apparently the "special".

During a maintenance session, my mechanic brought up a question I had never thought of. On a single petcock, does the stem mark what position you are using, or does the stub "point" to it like an arrow? Trying to determine which way is on or reserve, as there is no arrow stamp present, and i...

Hey guys, could definitely use a little assistance with my 77D. I recently had to change out my carbs and went with VM34s, and as many different people i have seen with similar posts, kind of expected it to come nearly ready to roll when I ordered them for a specific year bike. After finding out...

Hey guys, i changed my clutch this year and I guess I didn't put the spring back in the kickstart correctly because it will not move at all, just stays upright. I didn't notice until recently because i use electric starter and the bike starts and runs fine with no noises from that area. My...

I have a 77 D and i switched to a Mikes XScharge last year. Bike has been having trouble lately with losing power after riding a bit from killing the battery. Have checked all the connections and the output from the pma seems to be ok, so most likely the reg/rect is just being overworked. Been...

I have a 77 xs650D and recently had some charging issues with my xscharge PMA system. Ran through all of the tests and it seems ok, but one curious note was the 3 wire connector from the stator was melted. Is that why the charge wasn't getting through, and if so, what generally causes that? I...

I have a 77 xs650 D and I replaced the stock charging system with Mikes xscharge PMA last year. I need to know the correct way to test it out of the block before the reg/rec. The tests I have done were both the diode and ohm test on my meter, and I got O on both while touching yellow to yellow...

Hey guys, I have a 77 xs650D and the last few times I have ridden it has drained the battery. I had changed to PMAG last year and we checked the charge and was working fine. I am going to check a few things I already saw but also had a quick question; will running it with the high beam on...

Hey guys, first time owner here. Apparently these covers can crack. Need a RH crankcase cover (clutch plate side) for a 77 xs650D. Just need to get it to Florida. Thanks, Jimmy

1977 650D - I am having a shifting issue where sitting cold it does what it is supposed to, but once it warms up it seems to not downshift or go into neutral at all. Pretty sure it needs new clutch but I am having a really hard time locating a kit, as Mikes is out until at least late February. I...

Hey guys, I have a 77 D model and need a little assistance. I recently got it back together after about 4 months sitting in the garage. I have gone through the bike and cleaned the carbs, points, adjusted the cam chain and clutch, have new gas lines and filters and the bike fires up and idles...

I have a 77 D and am looking for a fender. Motolanna is out and i already have a fork brace. Anyone know where I can find a fender to fit this one, if it exists? Thanks.

Hey guys, just picked up a new petcock from mikes xs and was wondering if it is better to split from the source or come out with one hose and split after. Friend of mine has history of trouble with his Hondas when the split is right out of the PC, as apparently they have a problem with equal...

I purchased a 77 xs650D and have been trying to confirm the id numbers. I've gotten an answer for the number on the neck but still can't find the right engine chart. The number I saw was 46110. If that is wrong, please advise me. Thanks, James

I have a 77 xs650D and a previous owner had made the bike into a tracker style by changing tank and seat. They cut off the tank mounting "C-cups" that are welded to the front of the frame. I want to return it to a bigger tank and need suggestions on how to replace those cups, since you cannot...

I have a 77 xs650D that I am rewiring, and I am using the handlebar controls form mikesxs. I am just trying to clarify what sends the power into the LH switch. I cannot find on any diagram a wire listed as hot. Any help would be great. Thanks, Jimmy

I bought an EMGO 40-37600 ignition switch and need some information on what the 4 wires are for, since I do not have the factory plug to connect to and finding any kind of schematic is virtually impossible. There is a red, black, brown, and brown/white wire. Any help would be great. Thanks, Jimmy

I have a 77 xs650D and was wondering if all of the light and switch connections are supposed to be stuffed into the headlight bucket. I bought a new harness and factory handlebar switches and the leads are pretty long. Was curious if you could have some of the wires in connectors outside of it...

I am trying to find a wiring diagram of the gauge cluster. Have a few loose wires and need to find out where they go. Thanks. 1977 XS 650

Hey guys, have a 77 Yamaha xs650 and need a little help figuring out some wiring for my new rectifier/regulator. Bought from Mikes XS and sku is 24-2089. Diagram shows orange and blue, but I have brown and black. Any help clarifying would be great.
