    I purchased an oil adapter and filter from Jim Dishman, he has an eBay store that he sells them. link to one of his auctions - http://tiny.cc/ld33j . Jim was great to deal with and shipped the adapter in a timely manner!

    The install was straight forward. I removed the old filter and assembly, kept the main long bolt, the large o-ring and the copper washer for the bolt. From there I put the old bolt in position with the filter and inserted the adapter and filter in where the old filter hardware used tm be. The kit also came with instructions, but it was easy~ ]

    Here are the pictures

    Nice! I had a 73 back in the day. That year did not have the eccentric adjustable shafts for the omni phase balance system, but I upgraded it and sold in 75. It later grenade d under a subsequent owner. Not too many of those around anymore but it was a fun machine and comfy. I reckon that oil filter is unobtainium these days so nice job on the upgrade.

    So does the filter go inside the case? I have a 1973 TX750 out of the bone yard that I've been playing with. I read about the Toby Folick's oil filter mod, but have not tried it. :ear

    SOS- Yes, the filter goes right in the case. I have been following your post about your 73 TX750. Any updates?

    Thanks. I haven't got to the TX lately.Tthe electrical harness is really bad. I've got new pins and connectors coming to rebuild it, but they are backordered. Trying to get the F11 done in the mean time.

    That filter adaptor looks like a must have for these bikes. I'll be getting one once the project is closer to finishing.

    I think that color doesn`t fade as much as it yellows. making it darker than original. May have been an early clearcoat type paint. Gm had a color I wish I got on my truck called sunburst orange metallic that's pretty close. the 73 tx750 was is a pretty good looking bike but I had one so I`m partial to em.

    Not original, just repainted by my Nephew. THE WHOLE BIKE had been rattle canned satin black by some Monster Garage wannabe... I washed off a lot, but the tin needed repaint. here's a pic as she sat at the Bettencourt auction, neglected, abused, and I was snickered at when i bid on it... he went DOWN from the original start bid, lol I had one too, it was my hooligan bike when I was 16yo:lol3

    Hey Guys,

    Can you give me details on the oil cooler? Specifically, I'm wondering where ittakes and returns the oil. Does it take oil from the oil pressure sender and return elsewhere?

    I've been doing a custom without too much for mods. Full engine rebuild as well, pistons, rings, valves and seals. Bearings were all in spec so I left them alone.

    That brings me to another question for you guys. Like most, my omniphase timing chain is loose at 7200 miles. Its smooth during accel or decel but at constant load, it "rattles" pretty badly. If you've rotated this motor and looked, they come very close to one another. There's a significant amount of play in the chain. I'm planning to cut the timing chain and locking the balancers in place. Here's my reasoning:

    1. The balance does not balance the rotating assembly, it simply balances the mass of the crank/rods/pistons so it feels smother to the rider.
    2. Leaving it in place ensures that oiling of the rest of the motor isnt effected.
    3. Locking them in place ensures they cant get get all bunged up. Not sure if this matters, I need to look at it closer. They cant contact the rotating assembly then who cares right?

    Anyway, I look forward to any words of wisdom. I picked up one of the oil filter converters back when Toby got his first batch. Super nice piece.

    Oh, here's a pic of the bike recently.

    Does yours have the omni-balancer chain adjuster, or the the recall if it is a 1973? I only road mine for about 1 mile so I don't have a feel for how it will act, but I di notice the lack of vibration while riding. In fact I thought it felt just like an old ironhead sportster as far as the motor goes, but without the vibration. Mine is a 1973, but has the recall for the balancer chain adjuster and the extended oil sump.

    I have the extended sump but not the adjustable balancer. My motor is very smooth as well but when it isnt accelerating or deccelerating the counter weights, the chain slack makes a pile of noise. Too bad Yamaha gave up on this bike. I have a friend with a fully restored '76 CB750F and the TX is a way better motor (except reliability obviously).

    Assuming removing the chain willl not effect longevity of the motor, I could really care less about the vibration. Heck, until someone stole it, I rode my XR650R 5-10,000 kms per year.

    Thoughts?

    Put the tensioner retrofit on... it's not hard http://www.ebay.com/itm/YAMAHA-TX750-TX-750-ENGINE-CRANKSHAFT-COUNTER-BALANCE-2-1973-/160921550629?pt=Motorcycles_Parts_Accessories&fits=Model%3ATX%7CMake%3AYamaha&hash=item2577abff25&vxp=mtr
