Checking the sidewinder exhaust for fit. Unfortunately the dog decided this one is not going to get pass the frame. Back to the search for another.

Another dog?

Yes, a new pup. I had to have the Rottweiler mix put down a while ago due to muscle wasting disease.  It was painful to slowly watch him experience difficulty in standing up and then randomly falling down. I had to keep him on pain medication 24/7. It got to be to much when I had to hand fed him. Sometimes you have to know when to let them go. I held on a tad too long. I got this black dog as a tiny puppy last February so she's not a year old yet.  Cane corso per the breeder and verified by a DNA test. Lol. She's still breaking me in and weighs almost 100lbs.

Sorry to hear that frank,it does suck

Frank, sorry to hear about your Rottweiler. Neighbor has a pair of German Shepherds that were his son's, his son died in an automotive accident last year. They bark at things and keep others and animals away from his property. He has another dog and apparently they don't get along.

Glad you are enjoying her presence and she's breaking you in right...

Can't wait to get this bike together and learn to tune this Maxxecu.

[PeWe]

Lambda sond will help to tune it without several dyno visits.
And tune it to weather and altitude.
Unless using fuel injection that will do it right "by itself' when adjusted.

It will be interesting to follow this build and its result on the strip.

dragracer,will this MaxxECU also work together to help program your fuel injection ?

Yes. The ECU controls the electronic fuel injection system and ignition.  It will use a missing tooth trigger wheel and pickup. The Maxxecu is fully programmable with user parameters for fuel, timing, nitrous,  2 step launch control, Rev limiter, shift light output, autoshift control and many other features that I probably will never use. It works great in turbo applications as well as normally aspirated. If a sensor can be connected to it, it can control a function.

Frank,the Maxxecu must take some 'figuring' to set up

That's an understatement 😳.  Especially for my old school points and coil brain.

 Our Holley EFI when in learn mode always seems to outguess me and we break out a couple hundredths. My driver wants her carburetor back. We began last year with a can of flat race gas, that took a bit to figure out. I called it covid gas because it was in the can too long.

Ran into a problem getting the sidewinder I had on hand to fit my chassis. It was hitting on the frame as it made the turn to the rear of the bike. Fortunately I have a friend that had a big tube pipe that came off an old pro mod bike. I should receive it by tomorrow afternoon via FedEx.  I'm hopeful it'll fit this Koenig chassis without modification. I haven't done much to the project in the last few weeks so getting this issue behind me might kick start my interest in moving this build forward again.

[grcamna2]

Frank,is that SS?
The pipe that's on the way from your friend will extend further out away from the outlet of the header/collector before it makes the bend rear-ward ?

It's my hope that it will extend out before it makes the turn. I'll see this afternoon as the delivery is supposed to be today.

How did it look ?
There's a way to adjust the pipe flange where the springs pull it in;possibly tig welding a few stops?

[dragracer]

As much as I was hoping for a better outcome than my previous attempts using the Star sidewinder and then the V&H pro stock pipe, I struck out again. The collector exit isn't going to allow the megaphone to pass by the frame. I've come to the conclusion that any off the shelf exhaust will not work unless it's specifically modified to fit this chassis.  I'll be making a call down to Timblin Chassis to see if Walt can get this problem squared away. I don't want to waste any more time on the project until this is sorted out. Not giving up, just moving slower.

Frustrated but not defeated.

I imagine that header/collector is designed to be set in only that position(collector exit)and there isn't enough movement in it to adjust/pull-away from the right frame lower down-tube:that's how it looks.

A reputable chassis builder saw my pictures of the header dilemma.  His initial impression is the engine  wasn't set up in the right position.  I'm going to contact the chassis shop that did my conversion from Kaw mounts to Zuk to get his opinion on why 4 different headers won't work on the chassis.

I like your idea.

I haven't posted on this thread in a while. Last time I put anything out I let you all know I had run into a major stumbling block with the exhaust system.  After trying 4 different headers, I had to at5ccept the fact that no off the shelf, aftermarket exhaust would work on this chassis. I  had located a fella I raced with bsck in the 90s that currently builds custom headers for dragbikes and race cars. He agreed to work with me to build a pipe. I dropped the rolling chassis off, and within a week he had me ready with a very nice, stainless sidewinder exhaust.  I had him to do some other things for me like remounting the body. He did a good job straightening out a flaw from  the mold and it sits on the chassis much better at this point. Now I don't have any excuses to not jump back on the project. I'm going to give myself 90 days to complete everything and get the bike down the dragstrip for testing..

Standby, more to come.

That is sweet work!!

[RAFster122s]

Gorgeous work, very good at pipe bending and welding is putting it mildly.

[PeWe]

Beautiful pipes. Like a nest of snakes

[dusterdude]

Very niiice
