First Tracker Make Over

The tubing came today. Just a few little tweaks here and there and their off to the chrome shop.:thumbsup: I did make the 2 rings that weld to the headpipes and bought a HF tubing expander for the low rock bottom close out price of $11.95. It only has to expand both tubes that fit into the megaphones by 1/16" each so I don`t have to use the ridiculous split reducers supplied with the megaphones. Looks like I`ll work a couple hours in the mornings before the shop gets over 100+.🥵

I have one of those tube expanders, I could not get it to work. Probably using the wrong technique. Could you let us know how you get on with it.
 
Since it was 109 degrees in the shop and 70 in the basement where my lathe is so I made the collar for the haedpipe tube to fit in the exhaust port. I got 2 of the remaining SS flanges Gary Hoos had left and I have some flanges that were for MAC pipes. Both will work. I`ve already changed my mind about making these twice and I`m sure I`ll change it again (&) again. At least the flanges will have plenty of threads to secure them.:thumbsup: Its 8:10 and the temp is 106 so my production level has hit rock bottom. Only 81 for a overnight low but maybe a little work in the early morning.:shrug:

Cold front moved through. Only 98 in the shop.😅 I cut the head pipes to length, fit the collar and tack welded in 3 spots and faced them smooth. One less thing to hold on to. Each piece of tubing has to be made to fit and marked then removed to tack weld then reassembled. No welding on the bike.:yikes: It`s just killing me to have to weld in the center of the bend in the LH tube.:shootme: The large fin BBK is becoming a real pain in the ass. Much less room to fit the tubes. I plan on having this done by the weekend

Right side pipe turned out to be a real SOB. I finally got it to fit and run parallel with the left side (lower) pipe but to fit it to the bike you have to remove the front motor mount, magneto and left side lower valve cover nut then the pipe just falls into place. The large fin cylinders really throw a wrench into the works.:shrug: I`ll get them TIG`d and prep them for the chrome shop. What a PITA project.

Fab fabrication; Pipe perfection! Exhausting work!!
 
If you mean by "wrap around" as running the tubing on the outside of the frame, I`ve seen that done but I was trying to tuck the pipes in closer. It would be much easier than the way I did it though. Large fin cylinders really limit the style of the right side bends. Besides no challenge (ass kicking) involved.:laugh:
 
@halfmile do you have more details on your oil cooler setup?

I see that the return line is going into the finned oil cooler housing. Did you not want to machine away part of the side cover to get this fitting in there?

Is the feed port just tapped for the adapter fitting? what size lines did you use?

Thanks for the help!!!

The factory plug material was removed from the feed port and tapped to 1/4" NPT as was the return to the oil cooler housing. I used #6 stainless AN fittings & line. Oil passage in the side case was plugged as per instructions on this site. (somewhere ?). For some reason it doesn`t leak.:thumbsup:

Very cool. Did you make that oil filter cooler? Wondering if I could simple do the same to my Heiden cooler...

Does it use a stock oil filter under it? What size Earls cooler did you use?

Sorry for all the questions, looking for a way to keep the bike cool in this furnace that is DFW....

The oil filter cooler was from eBait. Uses a stock filter and not much of a cooler? The Earls cooler is a UltraPro 7 row 8 1/4" wide.

Glad to see those worked out for you.:thumbsup: When I built them they were for a stock 650cc barrels. The bends I made those with are not available any more and they were 1 5/8" tube. :(

So the new pipes you're working on are 1 3/4"? Wouldn't 1 1/2" be easier to work with, then step them up once or twice to 1 5/8" or 1 3/4"?
