When I check voltage with the bike running my multi-meter goes berserk! It goes from single digits up to 20 or 30 back and fourth and its barely readable. I tried another meter with similar results. This motor was in my other xs and charging fine before I swapped it into my 73. It is a 78...

I have the main wire harness for a tx650 from mikes. The wire colors are not the same as original. I messaged them but they do not have a cross reference. Does anyone have experience with this harness? Do the colors correspond to the colors on a different year possibly?

I have read a ton of stuff about this but I dont seem to have it right. This is a regulator rectifier that I had on my bobber years ago and it worked good. The bike runs, the lights, blinkers, and horn work. When I go to test the battery voltage, when running, my meter goes berserk. The...

I disassembled my fork to change the seals. There is a crack in the area of the seal. Rather than try to seal the crack I would like to replace it with a good part. There are some forks from tx500 on ebay. The part numbers for the outer tube are the same except for the prefix. Does anyone...

I am looking for the longest motor mount bolt. Its the one on the bottom center of the engine. It is for a 73 tx650. Its an m10x290mm. These came in different lengths for different years. 290 mm is 11.417 inches long not including the head of the bolt.

I got a street tracker last week with home built exhaust on it. It leaks at the head and I’m not sure what the idea was when they built it. The clamps were bottoming out on the head and the gaskets were not crushed. It appears that the pipes were only held in place by a slip fit as there are...

The top end is off of the engine because I had the head freshened up and the bores and pistons are new. I split the old cam chain and ran the new one through. I have a long piece of wire in a loop securing the ends of the new cam chain. Should I peen the new cam chain before or after assembling...

Has anyone here ever used a KMC cam chain. These are much less expensive. Is it a terrible idea to use a c-clip type master link on a cam chain? I am thinking that its a bad idea but someone might chime in and say they have been doing it for years...

I got these pistons and they are a little different. The oil holes are smaller for one. On the pistons that were in the bike the top and middle rings are two different thicknesses on the new ones they are both the same width although one ring has an all over black coating and the other one has...

I am getting up to 18 volts at the battery when I rev the engine. I have the xscharge PMA along with the regulator rectifier made specifically for it. I disconnected the R/R and did a diode check. I have never done this before. When I put the positive lead from the meter to the positive wire...

I have a 1973 TX650 that I got as a basket case. I have done a lot of work to get this thing road worthy but I could never get it to run quite right. Its the little details that count. I recently noticed that the mufflers that the po had on there only had a 1" diameter opening. I cant...

I have 12.4 volts at the battery. 12.4 at the kill switch. 12.2 at the coil. 12.2 at the connector to the pamco e-advance. It drops to 11.65 after the e-advance disconnected from the pamco rotor. With rotor connected I have 11.32 volts on the red wire at the pamco itself. Is this...

18" spoke drum rear wheel Rear steel chrome xs650 36 spoke 18". Missing the brake plate. All the spokes are loose. I think the previous owner may have been planning on putting new spokes on it but ended up going a different route. It appears to have had some rust on it that was cleaned up...

I have a 77 engine with bs38 carbs and a 2 into 1. It also has a pamco and PMA setup. It runs good when just cruising around. Here is the issue. The problem occurs when I ride it hard. After I up shift and grab a bunch of throttle it gives off a burp sort of backfire but continues to...
