Concours- Thanks for the replies, yes, the carbs are clean and the idle circuit is functional. Also, I did not know what to look for to see if I had the balancer adjuster fitted to my bike. Looks like it do ;-)

Thanks to SOS for asking that question as I did not know....

I have uploaded a picture of the adjuster and a picture of the bike.

Here is one of the 1974 TX750 - http://img840.imageshack.us/img840/1...cture001vq.jpg

and another of the adjuster for SOS - http://img200.imageshack.us/img200/2...cture004hy.jpg

Just joined after acquiring a '74 TX750 and already have a few of questions. 1. I've heard that synthetic oil is a problem with the clutches by being too slippery. Is that true for ones that are motorcycle specific oils and/or ones that aren't "economy" rated, ie. Shell Rotella T-6, Mobile 1 Diesel etc.? 2. Are there any diagrams for the spin on oil filter modification? That looks like it would work without removing the chain, unlike the BMW element option. 3. Does anyone have a source for an owners manual?

Do you have any filter's available. Thanks.

Just use a motorcycle specific 20-50, rated for wet clutch. I have been running Amsoil full synthetic 20-50 for 4,000 miles, no clutch slippage. Owners manual can be downloaded here: http://www.tobyfolwick.com/tx750/

A couple of more questions. 1. for Isettle (or anyone else with an oil cooler)-do you have a diagram or pics. of the lines to and from the cooler as well as how the cooler mounts? 2. for concours-what handlebar did you wind up using? The one on mine seems to be shorter than the ones shown in the "official" photos and I wouldn't mind a little more upright riding position. Thanks.

re. an update on mine: I now have about 500 miles on it after attending to the top end and other issues. It runs well but the oil/case temperatures seem warmer that I'm used to, hence the desire to add a cooler. I also need to correct a pre-existing dent in the fuel tank.

The bars I ended up with are the XS650 bars from www.mikesxs.com and the oil cooler is the specific one for the TX, issued trying to stop the engine failures. (Any Lockhart will work just fine) but the answer was the sump extension. Shoot your oil tnk with a IR temp gun? HOW hot?

I have used an instant read kitchen thermometer in the oil tank just after riding now a couple of times and get 180 degrees. Both times the outside air temperature was around 60. During the summer the air temperature can go over 100. I found a 750 cooler on ebay which is on the way, but have questions on routing the in and out lines between the case, tank, and cooler.

Did you use the Part #25-0654 bars from MikesXS? If I'm measuring correctly the ones on the bike have about a 2" rise, and I'm not sure on the pullback. Width is 28" and I wouldn't mind a bit narrower, but that would crowd the switches and brake cylinder.

Just found this post. I have good memories from the TX750-A I rode for 8 years. This was back in the 80's & I don't remember seeing any others even back then. Sounds like I must have gotten a good one. I didn't beat it , but I did ride it. Did have the electric start problem & got parts to repair. I'm thinking it had an adjustment for cam/balancer chain. Was the Purple color & did look good. Saw a sad one a couple years ago at the Mid Ohio swap meet. Hardly even a parts bike.

Yup, purple was '74, all updates included right out of the box, the starter still sucked though.

Sorry I missed this, yes, #25-0654 is what I used. You need an oil cooler with 1/2" ports, most are 3/8". The scavenge line is the one to cut, (goes to the TOP of the oil tank.)

Wish I could find some old pics of this bike. They'd be from the 80's. Used to ride with a guy that took his new KZ1000 home still in the crate. We could cruise together all right, but his throttle did much more than mine. I'd kick down twice and still do no good to leave his ass. But I still enjoyed the bike for what it was.
