Didn't the TX 500 and 750 come from the factory without any kind of cam chain tensioner?

The TX500 was also a short lived,short production run bike,some kind of mechanical suicide was going on with the 500's. Sounded good,ran good when new but eventually led to internal shrapnel.Ive had a XS650 and couldnt hurt it,fun buzzy kind of bike that never had a problem while I had it.

um edsel

Well sure I'll take those TM400 off you hands you just pay me for shipping and handling as for the Edsel parts I would sell them some people do actually want those parts for the simple fact is Edsels are RARE (i know there was a reason)... I paid $230 for it off Ebay (E(vil)Bay).. I have researched the TX750 and found that the main problem was the Omniphase cam. At high RPMs it would froth the oil and then your top end would be starved... The 74 actually corrected this issue but the damage to the reputation was done.. and with the modern oils and such these bikes are like any other just have to maintain them... least that is what I read.. Getting closer to wrentching on it...

A friend took a low mileage TX500 in trade about 25 years back.
It blew approaching 35,000 miles after running low on oil.'
Friend admitted he had no confidence in bike's longevity and neglected it shamefully. Felt bad, was enjoyable ride.

I for one hope it runs like a champ,Ive just never seen one on the road. Parts can be had for the thing? I took on that Airhead project knowing nothing about them really and kinda figured it out as I went but Im not a mechanic by any means.It was a satisfying thing to take it down to nothing and back up again. Trading it for an 05 V-Strom 650 was heresy maybe but the Suzuki suits my needs to a T. Good Luck! I'll check back in.

I have a friend working on a TX 750 also I think it is a 73 or 74. It really has a worse reputation than it should. His needs nothing internal to the engine just the cosmetic stuff, brakes and carbs rebuilt. It had a ton of bondo in the tank and a mural of a ferry sniffing a tulip(no kidding). Painted purple with the words "Shoops Hoop". It really was a flower power of a job. I will have him post up here maybe the two of you would have a lot to discuss.

Newby Post - Have Three restored Tx750's

Just joined and this is my first post. I'm basically into bmw airheads and Yamaha Tx750's. Have a 79 R65, 95 R100M R1150RT and three restored Tx750's: two 1974 and one 1973. One 74 was a good find that I got cheap (exhaust crossover pipe was cracked, replaced it and installed aftermarket exhaust, cleaned carbs and is now a good runner). The other 74 was a barn basket case and is now restored except for top end changeout/rebuild (using top end from another one I bought for parts). The 73 is a gem I found in June that is the cleanest 35 year old bike you will ever see. Replaced tires, throttle cable, battery and cleaned carbs and runs great.

Granted, these bikes died an early death due to initial serious quality/warranty issues, the ones I have are Ok bikes as long as scheduled maintenance is performed and you don't run them at the red line. I have accumulated my own stash of major parts and have a couple of good sources for the maintenance/rebuild gaskets/etc. (although they can be expensive-oil filter a good example).

Pic of the 74 restored one is attached. Will attach pic of the mint 73 later (the only pic is on my PC at work)

Cool2 parts easy to find

So far I have had no real problems finding parts for the old girl. I think thee hardest part to find for me was a left side sidecover. Took three months to find a rusty old p.o.s that i bought then two more have shown up on ebay, one in immaculate condition for a price I would never pay and another that was in excellent condition for $15. Now that most of the stuff for the house is out of the garage, I had the chance to wheel the old girl into a corner and pull off the carbs. The carbs will get a bath later on.. I will get pictures closer to November I want to take pictures of what the insides look like of the carbs and such before cleaning them up. If the service manual is any indication then this is one complicated beast (engine) and I am no mechanic so the going is going to be slow

73 Tx750

Here is my other running TX750 (not a very good pic). Was garage kept all its life -no rust (even in the gas tank. Needed tires, throttle cable, carbs cleaned, and timing reset. I added the luggage rack and crash bars from a parts tx I bought.

My other restored 74 tx (previous post)was a last winter project (have a heated garage).

The second 74 tx that needs engine top end rebuild will be this winters project. Gives me something to tinker on in the long northern Michigan winters.

Does the starter work on yours? All three of mine came with slipping or non-engaging starters. The starter clutch has 3 rollers that engage. The rollers have pins with a spring inside. All mine had a least one of these pins/springs busted. A real pain to get at to fix (need a special rotor puller).

I had this bike out and put 50 miles on it today. Get lots of looks and people always want to know what year it is.

Thanks

Whats up with the TX wheels everyone I have come across are in great condition regardless of the condition of the bike. They must have had something correct when it came to the wheel and spoke combination. Anyway if I end up buying it I wont have to worry about spoke replacement.

I have not gotten to the point where i am testing the starter... I do plan on tinkering with this and making it my Iowa winter project. As my garage is not heated but I have a good sized kerosene heater that keeps it nice and toasty as long as the wind not to cold...

Make sure you're well ventilated with that kerosene heater dude

Parts if you want them

Hey all. I just did a search and found this forum and thought I would post. I have a 1973 TX750 that I am looking to get rid of. It is partially taken apart and in my garage. It hasn't been run since the 90's and was in a neglected condition then but it did have all the parts needed to run as I did ride it a few times. It's really more in condition to be used as a good source of parts but could be rebuilt as well. If anyone is interested please let me know. I live near Atlanta GA. The bike is titled in IL and in my name. I am just looking to get it to a good home as I don't have the time or money to work on it.
