Did Ron run 1 5/8 pipes... on a standard motor...?I'd be about as concerned about running 1 5/8" pipes on my Norton motor as Ron Wood.
If you have time, it would be great if you could start a thread somewhere on your Norton tracker project. I'd like to see it live and in person when finished, if possible. I'm just up the road so to speak.I work out of a small garage. It can get crowded. My project is a Trackmaster frame that was originally designed for a Triumph Triple. I adapted in a
P-11 motor and trans, no easy fit. I fumbled around with different pipe designs but now I want to try the original pipes.
Two days ago I finally took my Goldstar cases down to a place in South Seattle called FLAME SPRAY to get a couple of bearing holes repaired. They build up the hole by blowing in stainless steel and then boring to size. $350 and it looks like a lot of work but I can't assemble the motor with sloppy main bearings. New cases are approx $2000 + shipping from the UK. I will let everyone know how this works out. This could save a lot of motors and gearboxes.
IIRC it was just after the first bend.Correct me if I'm wrong ( CMIAW ) but I believe one reason for the small diameter exhaust pipes was to minimize reversion. I read an article in CLASSIC BIKE eons ago by Alan Cathcart who described a pipe modification consisting of slotting the exhaust pipe on the underside and welding in a small piece of sheet metal as a dam to stop reversion. I don't remember the exact distance from the head. He took the bike (a goldstar), flogged it around the track and gave it a glowing report. I always wanted to try it. Perhaps it would help on 1 5/8 Norton pipes.
Throwing some dirt. Norton motors are good for that. Should be a great time.OK I won't do the pipe mod.
The trackmaster will not be a street tracker. A friend runs a 250 Yamaha DT1 at Castle Rock and the TEST&TUNE days. We are going there this Sat. to play with the Yamaha and it looks like I can put the Norton trackmaster on the same track for a very fun day. I will check out the details this Sat. From then on I will have to rely on two different friends who have trucks to get there. Looking forward to it. Sometime when you are in West Seattle you can come by and see it. It's got a set of R1 forks and a Joe Hunt magneto. Single Mikuni.
