Much quieter with the Porsche adjusters.

Hi. I was wondering, since it's been 8-9 months since the last comment, any long running problems/delights since installation? Like holding valve clearances better/longer and/or lower valve clatter noise? I too have some VW engine experience and favor the Porche elephant feet adjusters with the ball clearanced rocker Thanks

Ran mine all summer (several K miles) with no problems. Once they wear in valve clearance hardly changes. I still get a bit of valve noise at low RPM's but I think a lot of that is due to the wide clearance spec on the cam I'm using. I keep wondering if a bit more oil would eliminate that.

As mentioned, a couple checks/adjustments in the 1st few K while the parts bed in, then they seem to hold settings well.

buell88: Anybody have any idea who built the xs650 tracker used in the Draggin Jeans Ad on Pipeburn? May 16, 2017 16:24:09 GMT -5

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. Jun 7, 2017 22:09:52 GMT -5

craig8johnson: Not sure if this is the right spot or not but oh well... Jul 11, 2017 18:04:15 GMT -5

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. Jul 13, 2017 6:54:33 GMT -5

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. Aug 16, 2018 8:50:48 GMT -5

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!! Aug 16, 2018 8:55:08 GMT -5

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, Apr 10, 2021 2:14:13 GMT -5

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. May 20, 2021 1:19:09 GMT -5

deadlykittin: Hey guys,. i have a 82 xs650 special, super new rider, with almost no knowledge on bikes. So was just riding it, getting used to the clutch and all that. But i was noticed its really hard to get the bike to start, using electric start. And the kick pump--- Aug 4, 2022 17:09:55 GMT -5

deadlykittin: loses compression after the first kick. Ontop of that, i noticed it 1, wont go into neutral when sitting still. and now it dies after getting it started in neutral and going into gear Aug 4, 2022 17:11:01 GMT -5
