Gents, I've run into an odd issue with my triple clamps. I have a cognito moto billet top triple clamp for the 35mm forks (mine's a 1980 XS). When I went to install it, the forks would not line up into the holes. After looking at it a bit, it appears that the steering stem hole does not line...

Ok my goals for the Front brake are to have a modern, light pressure but progressive feel to the front brake. I'm not made of money so I rebuilt the stock caliper, fitted a drilled rotor from a newer Yamaha, got an 11mm bore MC (cheap evilbay variety), Mike's Kevlar brake pads (#29-3522) and a...

Hi guys, I've been fighting a high idle issue since I rebuilt my engine. I've cleaned my carbs several times, put in all new jets, inspected the diaphragms, replaced the shaft seals, new intake boots, etc, etc. I even bought a 2nd set, rebuilt those, replaced the shaft seals on those as well...

Well, I've always like Yammy's but this guy is fighting me every step of the way. I was having some starter overrun issues so I went to remove the clutch cover to perform the starter gear clip bending procedure and found metal shavings in the filters. Mostly in the right side filter. Man, it's...

Hey guys, I put an 11mm front master cylinder on my build using the stock single piston caliper. It works, but requires way too much lever travel and doesn't feel very powerful at all. I'm running a drilled rotor and stainless one piece hose. I got the 11mm MC from a Zuma and noticed that the...

I currently have the K&N pleated pods but the rubber around the filter at the front of the housing hits the frame's center support and they just don't seem secure after wrestling them on. I'm thinking of switching over to the Uni foam's but want to know if they clear the center frame rail or do...

Ok, I heard the infamous starter grind when firing up my engine for the first few times and pulled the clutch cover off to take a look. Found some bits of metal below the gear so took it off. As you can see from the pic, wear has started to happen. Looks like I caught it before complete...

Hey guys, was noticing that my starter would run a bit after the bike started sometimes. I was working on some other issues as well so I removed the clutch cover and basket and noticed that the #3 gear, the one under the c-clip (part # 5 on the parts schematic), wiggles around quite a bit...

Ok, I've been chasing after a hanging high idle after a full rebuild '80 650 with BS34's. Carbs have been done, new boots, etc. I just replaced the shaft seals too. Spraying around boots and manifolds show no change. Shafts are good too now. However, I noticed that when I press down hard on...

Ok, I think I've narrowed down my hanging idle issue to the shaft seals. Mostly stock internals but I have K&N's and straight through baffles. Carbs have been cleaned multiple times. I've gone from the stock pilot to a 45 to 47.5 and I can get rid of most of the hanging idle at 5 turns out but...

Hey smart electrical folks, I'm working on my XS build and am using a single speedo from an older yamaha. Anyway, I'm no electrical expert and have just enough knowledge to be dangerous. My question is how to wire in the single speedo flasher indicator light. Some lights like the speedo light...

Hi smart electrical folks, I have quick question I know is probably simple to the smart guys. I'm doing my own basement build which has been extremely fun. But I'm onto the wiring part and will be attempting my first custom wiring harness. I'm running a basic setup but want blinkers. I'm using...

Installing new bearings into my rear wheel after sandblasting and was wondering how tight the fit is supposed to be between the reducing collar and the bearing? My collar will not just slide into the bearing and I don't recall forcibly removing it. Is it supposed to slide into the bearing with...

So I was putting together the mag wheels on my project and went to install the internal spacers in the wheel and after looking it over, I couldn't decide what they do actually. The bearings all have lips to sit on so it's certainly not to space the bearings or support load. So, why did they...

Hi guys, I'm in the middle of my first build and have been looking all around to find how you are mounting the rear MC when using the aftermarket rear sets. Most I've seen are using either drum brakes or non-stock MC in a non-stock location. Can someone post up some pics of how they set the...

So I'm working on tearing down my '80 650 engine due to some leaking seals and such and to paint it. When I pulled the cylinder, I noticed the right hand piston had much more streaking on the piston around the skirt than the left side which looked really pretty nice. The right side piston was...

I'm in the process of an engine tear down to replace a bunch of leaking seals. Engine runs great otherwise. Anyway, on this build I want to paint the engine so I was thinking I would soda blast or glass media blast the engine to prep it before painting. My question is do you guys blast the...

I discovered that my stator side cover has a nasty crack in it around one of the mounting bosses. Argh! I'm looking for a left side cover replacement. My budget is very limited :( however so kinda looking for someone who's interested in clearing out some old parts. Please pm if you have one...

My subject line says it all. On the bike, the solenoid clicks but the starter motor won't turn. Battery is fully charged at is a 220 CCA AGM that I use on my 4 cylinder Zook. So i took it off the bike and bench tested it and it spins fine. Where do I investigate next? Thanks, Sci85

Hello, I've been wanting to do a 650 based build for some time now and finally ran across one that was too good to pass up price wise. The bad part is that the PO had already started the build and most everything is in boxes, unlabeled of course. Anyway, he at least bought some good parts...
