Hi there,
I'm new to the XT500 scene but owned a few YZ's and other bikes in my younger days, been looking for an enduro style bike for a while now and finally came across this one. She is definitely all original and from what I am told was resting in a field for quite some time before the previous owner picked it up, then he moved on as he had too many projects on the go. I just brought it home yesterday, the original tank is quite dented and has rust on the inside so he had an XT400 tank but it does not quite fit. I'll need to source the missing parts, and I think I may have already found a parts bike but need to go look at it in the next few days.

I tried to get it started yesterday, pulled the carb apart, cleaned it all out, it was not too bad. Next cleaned the points and checked the gap, checked the plug, had good spark and it was a little wet from fuel so looks like it is getting spark and fuel. Gave it about 10 more kicks and it fired, ran for about 4-5 seconds then I went to turn the choke off, probably too soon as it died then I could not get it going after that. Need to try again or possibly do a running start.

What year do you think it is, from the tank I would guess a 1976 from some of the pics I have seen. The serial # is 1E6-007828 and the motor is the same.

The plan is to try to get it going but then most likely do a full teardown and rebuild over this winter. Not going to do a full restoration, just replace and repair what is needed, give it a bit of a paint job but I want to ride it so I can have fun on it.

Thanks!!

That`ll keep you busy!
Just joined today too.Had an original `77 XT500 back in `80,it didn`t have the low-slung front pipe,so guessing you`re about right with`76.

Yes looks like a 76c, you can check the frame number on here by searching Google for xt500 frame numbers. The original pipe looks tidy which is a good start. Be careful buying a later bike for parts as some bits are slightly different.

Certainly looks like a C and theres too many parts on not to be one.
Frame number will confirm this and the bottom exhaust bracket at the bottom of the frame.

:w. to the Forum Bainer :!: You' re owner of an old XT500 1976 model. The yellow fuel tank arrives from a DT 400.

Good luck for your plan, whatever it is.

Thanks guys!! Yes its definitely going to be a BIG project but thats ok I want something to work on.

I managed to get the beast fired up today, put in a new plug, and about 10 or so kicks later it came to life! It ran ok but I am sure the top end and maybe even more could be redone, when I checked the compression after it was hot it was only about 50 psi so thats not good but thats what I expected. I am goign to look at a parts bike in the next few days, I think its a 78 XT500 so I am sure it will have some parts that will come in handy.

As for my plan for the bike great question! I plan to use it on and off road so I will need to get the electrical/lights all back up and running plus probably do a full motor teardown and the brakes/suspension. I like the looks of street trackers so I may endup changing the fork to something that has a disc, and possibly do a mono shock rear swingarm. It all depends on what I can find that works and of course the $$$. I have seen lots of info online about different parts that fit so thats good I just need to find those parts.

More to come!!

Starting to look for "bolt on" front ends. If I wanted to utilize the existing triple clamp from what I have found I need 36mm forks. Are most Yamaha street bikes from the same era 70/80's that have a front disc the same size? I see lots using Yamaha XS forks but they look to be 35mm, and some using ones from YZ/IT's also. Keep in mind I would like to have a working speedo as this bike will see some road use along with offroad too. Looking for some advice or options on what would be easy to find and not too expensive. Thanks

XT350 is the easiest
