rephase

Images of Bike Extra Parts Images For sale is a beautiful, near new, rephased Yamaha 650 XS that has been opened up to 700. Moving to Alaska and cant take it with. Modifications include Huges Handbuilt Rephased motor (https://www.hughshandbuilt.com/services/rephased-xs650-components/) Bored...

Food For Thought While this could be done with an XS engine I think the easiest way to build such an engine might be to use 2 rear heads on an old Ironhead Sportster engine with the front being the air pump and the rear being the power cylinder. An even better choice might be one of the old...

Hey, everyone. First off, I want to say this forum is a tremendous resource and I am very appreciative of all the info you guys provide. That being said, I am looking for some guidance. Ok, so here is what I am working on. Please disregard the seat/sissy bar fitment and the messy garage. The...

Selling bike as is. Bike needs crank replaced, carbs cleaned, and a battery. Comes with a rebuilt, rephrased crank and cam from Hughs. Top end is fresh w;it’s new cam chain and tensioner. Extra set of mag wheels and various other parts. Bike is in decent shape overall. Clean NC title...

I have a rephased (thx Hugh) now an XS750, with the Pamco electronics for the rephasing. I'm not using the green monster coils due to space limits. I'm using a Dyna DC3 mini coil, (dual output, dual fire; couldn't find a dual output single fire when I bought it). I know someone has done the...

Hi guys, my crank was rephrased by a local (at the time) moto engineer a couple of years ago. I asked him to do a right side advance same as most people seem to do. He was going to do a matching cam for me but ended up saying (after having the cam and crank a year) that he was unfortunately too...

Hey guys, I finally got my bike running (sorta). I am having some issues with timing, I have a 1975 with a rephase, pamco rephase ignition, Hugh's cam, and the crank was done at a local machine shop. I just re-installed the whole electronic ignition unit as per Hugh's guide. I will try to...

I've found specs on the 447 cam at http://www.650motorcycles.com/isky.html What I'm confused about is whether I.V.O means intake valve opening or intake valve open. I guess I'm confusled because it mentions that it was checked at zero lash then it lists various lashes?... Maybe the dude...

This may seem like an overly simple topic to make a post about but trust me, if you do it wrong there is some serious money to be lost! I just received my crank and cam back from Hugh and since I spent some extra $$$ because I of my inexperience with shipping 30lbs of parts in a USPS box, I...

So I did a rephase last year, had everything sent out to Hugh's Handbuilt (did and wonderful job), and reassembled everything. Ever since then my kickstarter has been "mushy". Is there anything you should do differently when installing the kickstarter assembly after a rephase? I'm almost sure...

Is there any reason I could not install a second pickup for the coils spaced 90 or 83 degrees (depending on 270 or 277 rephase) before the stock ignition pickup to operate a second coil for the right cylinder with an electronic ignition on an 83 Heritage Special motor? Seems to me that you...

new old kid on here. I am John Foerg in Muscle Shoals. Alabama. I [U]AM LOOKING FOR TECH INFO AS TO HOW TO buiild A 277 CRANK. wHAT ALL IS INVOLVED besides just turning the crank. Amy info appreciated. lINKS ECT. John Foerg

Sorry about the double post.... Here is the link to my original question, please respond with answers/concern there http://www.xs650.com/forum/showthread.php?t=22912 I have a 1975 XS650 that I am turning into some sort of tracker/cafe bike, this weekend the whole bike should go together, all...

I have been reading up on the rephase on the 650 motor and it sounds like a sweet deal for running it but the price tag does not. Is there anyone making the crank and cam regularly yet so the price tag has dropped? I like my bike a lot but I can't see dropping 3g into the motor. If anyone out...

The title really says it all, just trying to get some ideas for relocating the coils. Currently on my non-repahsed motor my coil is in the stock location. But when I do get around to rephasing, idk where in the hell to put them so they're in a good looking and functionable spot.

So, I am sure a couple of you have been thinking (or taken part in) about a rephase. I have decided, after all the questions and answers on this thread to jump in. My goal is to be able to have a smoother running cruiser. Something that will take me past my current 4.5k vibratory limit. I just...

So, I have rebuilt the motor and driven it prob about 2k miles. It was my first bike build and first bike ever really ridden. I must say, it's been a blast and tons of fun. With all of these good times came one repeating problem: vibration. I have done a bunch of things to make this beast ride...

Ok folks, I have been doing these for BikerMetric, but I know you would like to have them organized in one place... So here ya go... 1st article is about rebuilding your crank, and all that entails.. http://www.bikermetric.com/2011/11/techtips-re-phasing-your-xs650-by-hugh.html 2nd...

I was wondering if any machine shop would have the capability to press apart the crankshaft and rotate 3 splines and press back together. Im looking to do a rephase and as much as I want Hugh to do it for me I live all the way in California and don't want to have to ship heavy parts all over the...
