Re: "TZV500" Retro Rebuild;
Thanks!
Now to figure out what to do with the tail... For the body, it sounds like the TZ500 fairings aren't wide enough and perhaps the TZ700/750 fairing won't be much different however, I'll probably just order the 750 fairings to try and get something wider and then modify from there if needed (like Paul did in Houston!
For the tail - I like the slab-sided look as it really supports the retro theme however, not sure that I can make the pipes work without running the two top pipes on the outside under the body in some of these pictures...

I don't think that the right-side "inner-thigh warmer" pipe-routing is an option on the V4 as with the black AKAI bike below. That was more a way to accommodate the parrallel-4 configuration...! Still, I love that look!
The peak-a-boo cut-out look at the rear on the Blue Castrol bike below might be okay and that will certainly accommodate the two upper pipes for the rear motor...

Re: "TZV500" Retro Rebuild;
Looking good.
I used Airtech's TZ500 fairing. The 700/750 don't have quite the correct profile. And remember, the TZ500 from 1980/1 shared bodywork of the YZR500 of the time.
The change in tail piece reflects the change from inline 4 carbs facing rearward to inline 4 outer carbs forward and inner carbs rearward and finally the switch to square 4 of the YZR500 after the TZ500 was discontinued.
I am scratch building the TZ500J/YZR500 OW48R tailpiece. It is one of the looks that you can easily pull off with our square 4 layout. TZ500G/H not so easy to do.
Here is a nice period side by side comparison. YZR500 OW48R, YZR500 OW53 and a TZ500J.

And by profile, you mean the fairing silhouette - looking straight at the machine from the side on...?RC45 wrote:I used Airtech's TZ500 fairing. The 700/750 don't have quite the correct profile. And remember, the TZ500 from 1980/1 shared bodywork of the YZR500 of the time.
I'm okay with that - keep in mind that I am not in the process of trying to build a particular OW / exact replica TZ500, or YZR copy. It's more of an era / theme that I am going for. The TZ750 profile might be okay for me if it means less work on the mods to the engine area of the fairing (like you had to do...)
The tail - I'll have to work around the pipes once they're done, but I'm going for that slab-sided look again of the TZ750. I think that Airtech actually makes one without the "thigh-warmer" / upper can cut-out on the right... Keep in mind that the cut-out was there for #1 cylinder to come around to and have some equal length... It can't run that way on the V4...

Re: "TZV500R" Retro Rebuild;
I might have to drag something in from the annals of the TZ350 that didn't have upper pipes and run the upper pipe bellies exposed back there on the sides of the tail right under my arse...

Re: "TZV500R" Retro Rebuild;
The TZ500J shown here and the OW48R(R for Reverse carbs) share the same carb and pipe layout and bodywork. The OW48R got an alloy frame disguised in black paint while the TZ500 kept the steel frame.
The G/H TZ500 shares the same carb and pipe layout and bodywork as the YZR500 OW48. Width wise the TZ500 and TZ750 share the same dimensions - they are both across the frame 4's.
I chose the TZ500J fairing simply because it was the right one to represent any inline 4 TZ500 or inline 4, square 4 or V4 YZR500 from 1980 through 1982.

Re: "TZV500R" Retro Rebuild;
I don't know man... Perhaps the wire-wheel dream is a stupid bloody idea... Lots of work for my conversion as well - same as for Paul. (Only to end up with a lesser wheel technologically speaking...)
Up front it's not too bad. The Ducati wheel is a direct fit in terms of the brake rotor spacing! But, now the angles of the bloody spokes cause them to hit the rear of the R1 calipers! I have to source the Ducati Paul Smart / GT1000 calipers and make custom brackets to fit them to the YZF forks! (Discacciati makes a killer upgraded direct-fit 4-pad caliper, but they're 1000+ dollars with pads and shipping!)
The front Ducati axle is also a MUCH bigger diameter than the R1 bolt (at the bearings / spacers), so it's either source smaller ID bearings and make custom spacers, or make a custom axle bolt with Ducati inner axle dims and Yamaha YZF outer fork dims / nut thread...! Or, yes, I can always convert to a Ducati GT1000 / Sport Classic / Paul Smart front-end (forks triple tree etc.) Who knows what issues I encounter at the stem conversion point and the fork length and handling aspects are an unknown...
Thoughts? Ideas?

Re: "TZV500R" Retro Rebuild;
The wheels look bloody sweet in there though! At the rear the picture for fitment gets a bit worse in one regard...
The sprocket off-set is not bad at all! In fact, I might get rid of the Honda CBRRRRRR offset sprocket and take this thing back the other direction with the stock sprocket! Not sure, we'll investigate some more, but again, the axle bolt diamater of the Ducati is much larger. So, it's either custom spacers, and sourcing the right bearings etc. Or, perhaps just keep it all Duc (bearings, spacer ID, axle bolt etc) and just machine custom ID adjustment blocks for the YZF swinger. I'll still need custom spacing.
Either way, the R1 caliper hits the spokes, so it's back to a Ducati rear caliper and carrier with a custom mount.
All input much appreciated!

Re: "TZV500R" Retro Rebuild;
If you are thinking of some other caliper and custom caliper hangers - why not simply keep your current calipers and space them correctly with custom hangers?
And yes, it is not unusual to need to use a 5mm spacer with traditional Yamaha offset rotors to get space for 4 piston calipers around the spokes.

Re: "TZV500R" Retro Rebuild;
Because the calipers are lined up with the rotors now... Its the back of the caliper that is too deep that runs into the spokes! If I space them out, then they won't line up with the rotors anymore - I'd have to change rotors to some dished setup or something?
I think that it's more than 5mm that the caliper needs to move out - perhaps as much as 10-15 mm each side!

Re: "TZV500R" Retro Rebuild;
The rotors will need to be spaced away from the wheel until the calipers clear the spokes. Then have the caliper hanger machined to fit.JungleJustice wrote:Because the calipers are lined up with the rotors now... Its the back of the caliper that is too deep that runs into the spokes!

Easy test is to get some 1mm thick washers - stack them to 5mm place the between the wheel and the rotor. You only need to do 3 bolts each side. Remove the caliper from the hanger and place over rotor. If the caliper clears the spokes then that is the size of spacer needed.
If 5mm is not enough stack the 1mm washers until the calipers clear the spokes.
Now custom hang the calipers to suite the brake rotor spacing.

Re: "TZV500R" Retro Rebuild;
Yeh, I'd have one machined. You have all the original hanger diamensions, so shouldn't be hard to move the 10-15mm.
