I've been dreaming about a project bike for a while, but life kept getting in the way. Important things like both daughters deciding to get married within four months of each other, a son still in college, a car that really needed work if I didn't want to buy another, etc.

So when a riding buddy called and said his neighbor wanted to get rid of a couple T500s prior to moving I decided to go take a look. I honestly had no idea what a T500 was. I was into dirtbikes back in the '70's and streetbikes were not on the radar.

Cool old bikes--one a basket case--so I bought them. Sold the parts bike a few days later to help the budget and started cleaning the carbs on the '71 that remained.

I'll get running--while hoping for the best with the crankshaft seals--and decide where to go with it after that. Unlikely to be a restoration, but you never know. No crazy custom, probably, as I think survivors deserve to survive.

Looks like a good one. You're in the right place if you have questions.

Sure looks like it! Spent a lot of time reading threads and have learned a lot already. Happy to have found the forum.

DON'T USE THE JETS IN THE REBUILD KIT!

They are always wrong. Clean the jets or replace them with genuine Mikuni parts. Trust me, you'll regret using the jets that come in any aftermarket carb kit. The float valves and gaskets will be fine.

Ordered OEM gaskets, etc. Brought an '83 GR650 back to life a few years ago and received the same advice from the folk on The GS Resources forum too.

Quick update. I got another box of parts from the seller after I sold the parts bike. Had another set of carbs, so I've torn those down for cleaning as well.

Made a DIY soda blaster and did a quick pass on some of the carb bodies, but decided I needed to take a break long enough to create a blast cabinet. As it turns out, baking soda will in fact blow all over the garage unless you have a way to contain it. :D

Carb parts came in, but think I may need to order a couple of pilot jets before reassembling any of them. Hard to wait, as I want to take a shot at starting the bike to see what I am dealing with, but better safe than sorry. The pilot jets screw heads were marginally marred when I removed them. One still in the carbs from the '72 as I couldn't get it to budge. May take some heat to get it out.

This dirt was in the float bowl of the first carb I pulled off the bike.

Carbs are clean and I set the slides last night.

Spent a few minutes draining a bit of the old two-stroke oil out of the tank this evening.

Decided I would fill the tank with a different color oil (has green in the tank and in the line) so I can see the line change color if the oil pump is working correctly when I try to start the bike. Probably going to give that a try early next week after my final grades have been turned in.

Going to have a friend with a lot of experience building and riding two-strokers come by when I give that a try just to have someone who knows what to listen for if anything is wrong.

The rubber bit connecting the airbox to the carbs is in bad shape, but I think I'll use tape to seal it up enough to try to start the bike. Just want to know if it is going to run.

Next job, prior to trying to start it, is to drain the crankcase put a fresh 1.2 liters of oil in.

Suzuki changed the amount of gear box oil to 1400cc along with a modification to the internal structure of the cases to raise the height of an oil dam. If your c/cases have 1200cc embossed next to the oil filler the cases would benefit from this modification. It consists of a rubber curtain which is glued on, but requires the cases to be split to do so. It prevents oil starvation to 4th & 5th gears during prolonged freeway cruising. For normal street riding you will be OK (ish) until you can get around to do it.

You can still get the carb to airbox rubber from Suzuki AFAIK, but they often appear on eBay.

Cheers Geoff

Thanks, Geoff. I had found the info about the modification, but I'm not certain this bike had it done. At this point I'm just wanting to get it started to see if there are any significant issues with the bike.

I'll tear it down and check to see if the dam has been added later, but I'm just wanting see what I'm dealing with before I do.
