XS 650 Chopper Re-Phased!!
November 6th, 2009 | Uncategorized | 21 Comments »Re-Phased XS 650 Engine. Bored to 707CC, Ported and Polished head, Custom intakes, Port Matched Carbs and Intakes, Dual Lectron Flatslide carbs 34MM, Custom Pamcopete Ignition (all electric baby!!!) 277 Degrees of Re-Phase, all done by myself. Just got it running in this video, needs tuning and timing, a bit rich still, but seems to run fine otherwise.
DAMN!!! That sounds good! I need to get off my ass and re-phase one of mine…The price of the cam is what’s scaring me…More vids please….
Cam was CHEAP. Just cut, bore, sleeve, weld and make sure its all square!!!
Sounds tuff man. I got mine here on the tube as well. I just have stock pipes cut off at the muffs, would like to get actual headers for a deeper tone.
The pipes on this bike are about the same length as the stock headpipes. 1 3/8″ ID
What as the jet size for the open pies?
Pipes I mean, I think I was hungry
I’m Using LECTRON Flatslide Carbs. They don’t use main jets, but rather different tapered needles. I’m using #5 Needles though, if that helps?
I bet shes alot smoother ride since the rephase
AWESOME. I want to build one…
I bought one from Ebay for $300 this guy had a few, and a really nice red one that would have been really cool to restore but someone bought the other three, good luck with the build
sweet punksalar!! my dad and I had our 79′ xs 650 bored to 753cc and at 707cc yours is really cool!! where did you get your weld-on from? 5*!
It’s not a kit. I bent the tubes and welded up the frame myself. I built the bars, seat, frame (back half at least), wheels, etc…
Awesome! Can I pick your brain about that?
I’m looking for a good method to make sure it goes on straight. I mean, I can weld together a back part just fine…but how did you make sure it’s on the rest of the frame straight?
sweet man, you do a hell of a good job
I read your whole build thread on that 4×4 board. I envy your ability to do so much of the machine work. I just got my XS, so I’m learning as I go. I’m keeping it bratstyle because I know what’d happen if I tried to line up my own hardtail frame. I don’t have near the patience you do to spend so much time on the forks, wheels, etc… Your thread was great motivation to let me know that anything is possible. I don’t find the XS650 boards to be much help. They hate the idea of cutting em up.
You need a frame jig. Make sure you keep a motor bolted in the front loop so the front half isn’t tweaked. The chopperhandbook website has info on frame jigs.
cool !
that motor sounds great, once you rephase those things it almost has a sound that would stump a harley guy if they werent looking.
wow. that sounds like a BEAST! good job!
Cheap option,go down your local steelyard and get an offcut of big section RSJ or Hsection or I beam whatever you call it over there,and weld/bolt stuff to it,it aint gonna bend anywhere,we built a Honda chop on one,cost 7 quid.
It really seems to rev very freely, Sounds Great!
What camshaft did you use for this? You mentioned above that you cut, bored, sleeved, and welded, but did you start with a stock grind or is it a performance grind that you are running? Is there a link for the cam rephasing operation? A few pics would definately be a plus, I have an engine just waiting to be done.
