100% right Cecil, I'll aways be a TZ350 man at heart as they have the perfect balance of power, weight, braking, etc and are just the best racing bikes ever. The 750's are of course monsters and command a little respect or they quicky show you who's the boss. As KR said "TZ750's have too much of everything" 😄 That's why we love them.👍
A crude motor when compared to the NSR’s and YZR500’s but absolutely thrilling to ride these beasts and a pleasure to work on, owing to their simplicity. Second most saddest day of my life when I sold my TZ750…will always miss it…
I am 68 and although there never was one in our country, we all knew about the TZ. This is a wonderful piece of engineering, a wonderful historical machine. Please keep it alive ! Trinidad & Tobago. West Indies.
Thanks so much for letting us see the piece of Tz history my father and uncles raced td and tz through the seventies and eighties so tzs have a special place in my heart
No but the same layout and cc, the TZ750 motor complete with gearbox was built by Yamaha from 1974 to 1979 for road racing, and famously the odd dirt tracker. The VMax-4 was snowmobile only (no gearbox, longer stroke etc) and came out much later, 1990’s I think. Nice motor though and I wonder if anyone ever converted one for use in a bike?
Yes, but everyone was so used to the almost bullet proof TZ250/350 clutches that easily lasted a whole season of pure abuse that only getting two or three starts from a TZ750 clutch seemed terrible despite its increased size. But when you double the power and add some weight that’s what happens. On the plus side because the crank rotates backwards on the 750, reversing the thrust side of the piston away from the massive inlet port, piston life doubled compared to a 350. 😄
Cantilever rear suspension with the long mono shock was standard on most Yamaha TZ125, TZ250, TZ350, TZ500 and TZ750’s. TZ250 & 350 “C” models (1976) where first from memory. It was a massive improvement over the old twin shock rear ends especially for the bigger bikes that wanted to tie their chassis in knots.
One of the best motorcycles ever to have raced as a young boy people,raced these on the roads off Northern Ireland ☘️☘️☘️☘️☘️☘️ big respect 💪😉

2 stroke engines are so simple to work on. Just have to make sure the jetting is spot on.
God what a beautiful beast she is
Totally

I proper love those bikes, grew up on LC's and raced against TZ's in open class club racing on a big 4 stroke. The smell.....
Congrats!!!! I'm 64 myself...so my point of view, sexy, so clean, so honest just everything it should be!! Thank you .
Very nice liked this, it's good the legend is still alive.
I am so jealous!
All the best!
10/10…Top job! 👏👏🏍️❤️
With unlimited funds, I would have one, just wicked machines.
Nunca tinha visto um motor de tz750 aberto. 🇧🇷🇧🇷 incrivel.
Holy moly this is beyond wonderful , I can almost smell it. I'm not in the least bit jealous , where do you live?😂😂
Fast as a modern gp bike with 1/4 as many parts.
Awesome👍
Brilliant! Good job. Is this the same engine Yamaha used in their Vmax4 snowmobile?

All that classic power going through a 160 tyre on the back ….
Actually a 150!, but you're right. Back in the day it was KR124's and KR164's, that's scarey!
140hp out of the crate.
Much more available.
Didn't these have a reputation for eating clutches at the time?

Cool 👍👍🍻🍻
Be cool to put one in a BANSHEE😮
So can you get genuine Workshop Manuals like you can for road bikes? Also 'Microfiche' parts lists etc.
Parts lists are available online.
Yes, they came with them from Yamaha, I doubt Haynes or Chiltons do one though 😃
Rebuilding an iconic 2 stroke race bike is fine, but clearly you need some help with laying slab paving....😁
33 💨👍🏽🏁

That bike is a dream! I wonder why it has three silencers on the right and only one on the left, instead of two on
each side.
No room for 4 fat round expansion chambers underneath the bike so one pipe had to go around the back of the carbs
??What is that rear suspension layout?? and length i've never seen before.Whywhy?🇯🇵

Do these want Castor oil in the fuel?
Sure do, Castrol A747 15% castor oil
