The trick to getting. The new chain over the spocket. I know you pry on the chain..Some pics would help.Thanks

So basically my right exhaust pipe blows smoke. It is not a lot and it has done it since I got it last year. It is just the right exhaust. I have heard that this might be because my right cylinder is loosing compression. I'm not really sure. I'm just wondering what you guys think about it and...

Hi, I have a 1979 XS650F that has about 400 miles on it since the Cafe style rebuild. I started with a rough but low mileage bike that had about 7,000 miles on the odometer. I went completely through the motor and transmission. The transmission gear dogs and shift arms all looked good in my...

Hi there, brand new to all this so please go easy on me. I have a 1972 XS650 and recently had my engine rebuilt...so far 110 miles on the break in and the vibration on the bike is intense...so much so that I had to stop driving after 40 miles today as my hands and arms were numb and when I took...

I thought my XS2 was standard, and runs just fine, but when I measured the cam timings I got: Inlet: opens 58deg BTDC, closes 90deg ATDC Exhaust: opens 65deg BBDC, closes 50deg ATDC These are the times at which the rocker contacts/releases the valve (clearances 6 and 12 thou), so may not be...

Hey guys got another bike for spare parts, support to be a 1981 xs650 heritage special, here is the engine # (wasn't on the list) beginning is 5v4

Bike is a 1980 special with a 1977 motor. Motor is a 277 rephase running BS34 carbs and using the stock wiring harness from the 1980 bike. Pamco ignition and a PMA from Hugh as well. The bike is not running on the left cylinder. It ran fine a few days ago then I took off the exhaust to...

Hi, guys. Ive been jerked around too many times by these 71 38's. Toomanyxs1b Had posted the early carbs used a throttle arm on the carbs with a quicker action, maybe for sales? Xsjohn tweaked the arms on his 34's to achieve this. I dunno. don't like it. I have a set of 74 carbs with the...

Hi, I have to open the lower casing of my engine. I've just figured out that the double raw ball bearing of the transmission mainshaft is out of order. The first ball raw,from the clutch side, has an obvious clearance. I'm just wondering if that's possible to open only the lower casing and...

New to the XS650 realm, but not new to bikes. Been looking for a project for awhile and ran across 78 Special that was already hardtailed. Couldn't pass up the deal. Anyway, it runs rough, as expected (the PO wasn't quite the wrench turner he claimed to be), but I'm working on the rough running...

Hey Portland area folks, I'm doing some prep for riding tomorrow and when i went to test fire my bike, the kick start lever snapped off. Anyone nearby have an extra? Would love to find one tonight or tomorrow (Sunday) morning. Really need to ride tomorrow! I don't recall if these changed...

Hi, hmm... about a couple of weeks ago, I noticed with my TM34-2 carbs, that the left hand plug were looking allmost as new, only with the tip a little bit colored.. The other plug looked as it should... I though maybe something had changed with the mixture, and got a hint from the forum it...

OK, so here's the deal. I bought an 81 XS650 Special a few months back that had typical charging system issues. Come to find out the rotor had a short circuit in it and was only reading about .2 ohms. So naturally I replace the rotor. And the problem was fixed, My battery was seeing around 14...

Well, first of all, let me begin this thread by saying I AM AN IDIOT. I did a full top end job on my '80, and got everything back together and torqued down. While trying to set ign timing by finding exact TDC (using a diy piston stop and degree wheel) I dropped a bolt down the spark plug...

Just got done with an engine rebuild on my 81 xs650 special. Started it up after getting the motor back in and its running on pretty much one cylinder. It's getting spark, I checked it on the side of the motor. It's theoretically getting fuel, we sprayed ether into the carb on the weak side...

Newly arrived 79 Special with 20K miles. It has not been treated well. Compression left is 102, right is 65. Ouch. My next step is to check the valves. After that? Thanks.

i guess since i have metal lying around, if i see an opportunity to save a few bucks i can't resist. some 1/4" aluminum, 4 machined aluminum standoff bushings, 4 flathead socket screws, a couple nylon insert nuts, and voila... careful layout work required, but the only real function of the...
