This method is very time consuming and your working in very tight spaces. If you already have the engine out, I'd say just take off the very top part of the head. You could try w/o taking out the Cam. Then you could use this method, but you won't be working in such tight spaces. Or you could take the Cam out and once the Cam is out, along with the rocker arms, those seal will be right there under the valve springs. You'll still have to compress the springs some how and get the collets out.
Fix em, ride em, maken em better. Loven these old school twins.
Sorry to jack this thread but, I began to try and tear into my motor after work today, and just from trying to pull the top head cover off I stripped both the top right and left cylinder side counter-sunk Phillips screws( ya know, the ones on either end of the cam shaft)... What would y'all recomend? Easy out?
Ok so I got the valve cover off finally, new question: Is removal of the camshaft neccessary? I don't have a chain breaker tool and don't want to buy one, and the valve looks pretty exposed? Can't I just compress the springs pull them off and change out the seals easy-peasy, or am I neglecting something?
>Is removal of the camshaft neccessary? No, I was just thinking that, so you could get the rockers out of the way.
>I don't have a chain breaker tool and don't want to buy one, and the valve looks pretty exposed? Can't I just compress the springs pull them off and change out the seals easy-peasy, or am I neglecting something? If you can get at them, great, I've never tried. You can remove the cam w/o breaking the chain. There's write-ups here, you just slide the cam bearings out, then it's loose enough to get the cam out.
BTW: your in uncharted territory for me....

I am going to try and replace my seals Friday night. First I will get the bolt for the compressor from the local bike dealers nut and bolt box and turn the pipe joiner down to right length on daddys lathe. Wish me luck coz I am going to try and do the job in a couple of hours as it will be eating into Friday night beer time.
Getting the cam out with out breaking the chain isn't hard to do. Take the tensioner scew out. Lift on end of the cam, pull the bearings off. Do the same on the other end. With a bit of wiggling and twisting you can slip the chain off the cam and pull the cam out from under the chain.

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.

trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!!

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon,

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
