Finished the Triumph build
« on: February 12, 2015, 11:09:29 AM »
 I been working on this 70 Triumph 650 for several months. It started off as an engine and frame. 92 Yamaha FZ600 front forks, Triumph wheels, Routt 750 kit, forged 9.5 pistons, aftermarket connecting rods, nitrided crank, slightly hotter intake cam and a bunch of other stuff...

         

         


   Yesterday was the first time it ran. Previous to the video the machine was run for about 20 minutes on and off at 2000 rpm to break in the cam and see if any parts fell off....

       Turn up the sound and wait...

Gorgeous interpretation... 

I remember Sonny Routt from back in the day.  Always wanted to drop a 910cc kit on a Triumph.

Nice job.

    You forgot the Brat or tracker key word. I didn't even look at the pipes. I'm glad the too loud crowd caught it. All joking aside and I really am just having fun here. I do think it looks nice and would be a hoot to own/ride.

We used either modified 850 Norton cranks , or a Moldex billet crank to achieve that kind of displacement way back then . Duncan Campbell in Joplin MO had a bad fast Triumph street bike using that formula , shook like a paint shaker though  :D

  Dusty

I do not recall, not having ever pruchased a 910 kit just how Sonny did the displacement.  I want to say on bore only, required opening the bottom end holes to fit the jugs.

Paint shaker...  :D

Nice work Rough. Is this bike for you or someone else?

I remember Sonny at the local drags. "Sundaaaaaaay Niagara!!!"
I believe it was Sonny that had the plate on the triple clamp that said "This bike turns times others dream of"

  Pete,this bike is the one I always wanted to build. All the mechanicals in plain sight. The oil filter on the return line to the oil tank is a common update. The alloy oil tank only holds about 2-1/2 quarts so the 1/2 quart of the large filter is a little extra...It's a common Jeep filter and after break in it'll get a  black Wix filter...I fiddled with the cam timing for more mid range power and the bike is geared for less RPM in high gear than normal. Loud? open pipes, but I was just jerking the throttle for the video...And this bike isn't for riding in the rain or on long trips. About 365 pounds with 55 hp is great for scattering wildlife on rural roads.
 This Routt 750 cylinder has Triumph part numbers used back in 1970 when Routt was hired by Triumph to build about 250 750 kits for the new 750 OHV class in AMA racing.

Almost makes me wish I lived somewhere cold so I'd have time to work on a project like this instead of riding all the time  ;D

Sounds better in person.  There will be a pair of Triumphs running around the Finger Lakes this summer.  His will be the prettier one

 If a Triumph doesn't start on one kick it's broken or extremely cold. First a kick through with a clutch pulled in to free the discs. If cold, flood the carbs and one easy kick with the ignition off to prime the intake, then a good kick.... I noticed when fitting electronic ignitions the engine needs a stouter kick than for points ignition to get the electronics to fire the coil.
 The Moto Guzzi is the only bike I owned with an electric start. I actually enjoy jumping on the start lever. It's part of the bike experience, like dressing in dead animal hides....But....yea rs ago I performance built a kick only iron head Sportster. When cold it started on one kick,but warm it could take too many kicks...One time I was kicking away at a gas station when a rather substantial Harley rider came over. He hoisted his mass up in the air and came down on the starter pedal,the engine started instantly. I learned to do it straddling the machine and winging my skinny ass way up in the air and not kicking from the side like many Harley guys do.
 The 70's Ducati 750 V twins and Triumph Trident were very easy to start. 850 Norton required a stout kick. The Shovelheads were a matter of technique like the Sportster. I had a BSA A10 and Triumph 650 with magnetos and manual spark advance, a lazy kick without retarding the spark was usually interesting.

I love it when nothing falls off and nothing leaks out! That's a nice machine. My first motorcycle was a very rough '57 TR6 that would kick me over the bars but it was mine so being a foolish kid I took it apart and rebuilt it. It turned out OK, not even in the same universe as yours but it ran. If I wanted to go somewhere I took one of my Dad's Hondas. Looking at yours makes me think I should get another one!

Lovely bike, but I'm glad I don't live near you and won't have to hear it. Bad enough around here already with all of the "life savers" running up and down MD 67.

 The bike even has a few Italian parts, Tomaselli  headlight brackets and hand grips  ;-T.  The bike is loud but nothing like a typical Harley. I was twisting the throttle for the video inside a closed shop. I fabricated an exhaust crossover pipe similar to Moto Guzzi and older Ducati V twins. Crossover can help tune the torque but they also reduce exhaust bark at idle and part throttle.

   This photo during construction shows the exhaust crossover, hidden battery and  70's Honda 750 foot pegs.

 


    And the other side.....My wife made the seat cover , a formed plywood base.

Just needs a couple number plates and you can bring it to Paradise Speedway and run the shorttrack and TT on Saturday nights.  Great job.
