Tri Z Engine Build

[El Camexican]

I'm curious, what's the company that is calculating your pipe design? I've used a program called the "Pipe Wizard" to calculated pipe dimensions but have yet to build one. On a side note, I just put an NOS Bassani on my Z and Wow! what a difference from the DG. The Bassani hits a lot harder than the DG but has a more narrow power band. Of course, you would expect that from the different designs. The condenser cone on the Bassani is steeper and shorter than the DG.

I'm hoping RPM Works can do it, but the link on their site for ordering specs is non-existent, so I sent them an email, but no answer yet. I'm sure there are others as well. I'd prefer not to get a pipe off the shelf. I have a bunch of old 250/300cc dented dirt bike pipes as well as a spare DG that I'm hoping I can cut up and cobble together into the configuration the pipe programed spits out. If I can and it works I may get a nice one built. I may contact Dyno Port as well. They've made them in the past, but they might not do a custom, but you never know, as they say in Spanish: "With money dances the dog"

Jemco in Texas builds a great pipe, Oscar Mayer is very happy with the pipe they custom built for his son's quad.

They should have jigs for a Tri-Z pipe.

Look what I found with a Jemco search

Guess I'll send them my spigot diameter

Maybe they make a pipe with threads on it that you can screw either spigot onto by now.

^ Well...... I guess someone grabbed the wrong part. They have been building pipes so long, I guess their time was up on that one.

Tri-Z decals look very nice.

All your stuff looks nice and is very clean and well built.

I dig the Katoom theme, plus it matches your other hot chicks...

Here's how I came about the measures:



I made two etchings at the same time so I could compare them, as I said the first measure was done quickly with a rule just redone with a caliper and it reads 51.7mm ish.

Spoke with John at Jemco today and I think he'll be making the pipe. To say his website sucks would be an understatement, but I'm not looking for a website, so I'll give him a try.

With spare time on my hands I pulled out the decals and made the transition back to Yamaha. If it ends up running like crap its better that people don't think it's a KTM

Any updates?

The Jemco pipe has been sitting in Laredo for about a month waiting for me to pick it up. As soon as it's mounted and tuning begins I'll be posting.

It`s really nice .......i like it alot !! Don`t get it dirty !

When are you coming to see it?

Finally got the pipe home. Looks very trick from a few feet away. Get a little closer and it starts to lose a little of its “wow’ factor. There is a dent that I didn’t notice when I unpacked the pipe. It could have happened in shipping, I have no way to know, but I hope I can pull it out with a torch and a wet rag.

I am very aware that carbon steel is a mother to TIG weld, so I’ll let the close up photos speak for themselves. I will however say that I did request a third spring hoop that I didn’t get (offered to pay if need be) and also I requested that the collar fit directly onto the cylinder snout and gave dimensions. It ended up coming with the larger collar, but that’s fine as I have one of Muthey’s nice little collars that will fix that right up.

I plan to finish the weld on the mount up and add a third spring hoop before shooting some WD-40 in it tonight to make sure there are no pin holes. At least with this pipe I can heat it and weld on it and it won’t look much different.

i've only seen gas welded pipes . . the "old" guys like dave miller and harry klemm are masters at gas welding . . the shape of your pipe looks cool, but yeah...your welds look like i did them....on a GOOD day.

[ironchop]

yeah. I`ve seen better tigs on carbon steel than that. I had trouble with cracks in tig welds on carbon steel but I`ve never had an issue making a clean bead. Really, it`s hard to armchair quarterback from all the way over here so maybe there was something else going on I didn't realize.

outside of that, I would be most pissed about that good-sized dent. That's not good for any 2smoke pipe as you well know and wether or not it got dented in transit or before it was boxed, it should be priority ONE to make sure the pipe gets to its destination with nary a ding or dent. Bad form there.
