I believe the YFS200 and YZ80 reed valve are a direct bolt on to TZ750, so could one also use the manifolds from these.......?
Look for the Blaster part numbers. Many YZ80 models had smaller reeds.
I had a 750 top end on a TZ350 and I used those reeds but I don't remember which manifolds I used. YZ85 are at an angle so they won't work so it makes me wonder in the blaster or YZ80 are straight on. If so, they should work.
The only manifold I found that fit the bigger bolt pattern and the carb fits on straight are Yamaha Tri Z. They also have a fitting for a crossover tube though.
yz 80/yz85 are same pattern as stock rd. i assume you are looking for the larger bolt pattern?

Need them for my TZ750 project.

Need to know if any other motorcycle be used as a donor for the Manifolds.
The only manifolds which fit correctly on TZ750 cylinders are TZ750 manifolds. People have tried for years to find a different solution/option. It doesn't exist.

Where do I get.those then?
Your best bet is to enquire on the North American Two Stroke (NATS) forum. Lots of racers there.
From TZ-Mike or from Yamaha if they are still available.
TZ-Mike used to be a member on NATS. Not sure if he still is.
This guy in Hollywood might have some, has tons of TZ stuff. -- https://www.ebay.com/itm/TZ-YAMAHA-250-350-NICO-BAKKER-ORIGINAL-GAS-TANK-ALUMINIUN-LATES-TZ-MODELS/183764105028?hash=item2ac931b744:g:c0AAAOSwQJhUddp2

^^^^Looks like he's got mostly 250/350 stuff^^^^^.............there's a guy in the UK that has a set on eBay right now, would end costing about 400.00 by the time you get them here. He's actually has a lot of OEM and replica TZ stuff.
I've gotten them from TZ- Mike before. Another option would be the billet style manifolds so I've reached out to a couple guys to see if there's something available. A couple of the early banshee monoblock cylinders used CR125 reedcages that are the same bolt pattern.
I'm almost positive I have a set of tz reeds and intake boots on the shelf. Want me to look?

That would be great. Thanks.
One of the people i reached out to was Chariot Racing because i've been using their billet banshee manifolds more and more and i just got a reply back: "Yes they are that bolt pattern. They fit perfectly. Boots for 35 to 41 mm carbs and up to 49 mm with modification to the intake. Just a little grinding." So here ya go:

Two things to consider:
1- If you are using OEM Yamaha TZ750 or Blaster reed cage assemblies, the OEM (or TZ-Mike) manifolds will have the 'ears' which protrude into the cage to smooth the flow (just like stock RD manifolds) and fit into the reed cages.
2- If you plan on using V-Force reed assemblies, the 'ears' are irrelevant and will need to be trimmed off the OEM Yamaha (or TZ Mike) manifolds, so an aftermarket billet manifold, with a smooth face, will work just as well.
:twocents:
Sorry I forgot about this I'll look this weekend.

Folks my project is nearing the end.would appreciate any help procuring TZ manifolds.
have you reached out to jim hinshaw @ fast from the past? he doesn't sell them but probably knows who does. or contact fondseca. One of them knows.
and what happened to mfactory west and tz mike? I know he used to carry them. :twocents:
Do you need 4? I think I have 2.

Unless these ^^^^^ will work for you there aren't a lot of options. TZ Mike is your best option. No, they are not cheap. Looks like you missed out on the set I mentioned were on EBay awhile back.
