Looking for mechanical advance assembly, let me know if you have one for sale! Thanks

Hey gents, just spent some time reading through threads in relation to this problem. Using a timing light I get a nice consistent view of my timing mark right at the tdc mark on my sticker. When I rev up the mechanical event weights throw out consistently at or around 3000 rpm but my timing...

One of the spiffs of working at an automotive school is access to fun toys. I had set up my carbs using normal methods in the fall. I suspected my idle mixture was a tad rich as my most stable idle was found with my idle mixture screw pretty much all the way in running a 45 pilot jet. I...

My bike engine experience is pretty limited. I've worked on solid lifter BMW engines a million times and have a good sense for what valve train noise sounds like loose and tight. I'm in my final tuning phase on my XS and I've got my valve lash set at .004" on the intakes and .006" on the...

Hey guys, I am hesitant to make this post, I know there are quite a few threads related to this issue. I was going to give it another go on my own tomorrow but I'm feeling pretty deflated at the moment. Turning wrenches on cars for 15 years I must have bled a couple hundred master cylinders but...

Greetings all. Ive got a 74 tx650 with bs38 carbs. Carbs were overhauled by rick at oldschool carbs. Engine is freshly rebuilt with a heiden 750 kit. I have not been inside my carbs to see what jets are currently installed and when Rick did the overhaul I had told him the engine was going to...

Hey all. So I was setting up my clutch adjustment today and realized there was too much space between the actuator and the clutch rod. Took a look at the diagram and doh! Pretty sure I have forgotten the ball bearing that goes between the clutch rod and the push crown on the clutch pack side...

Posted this on my build thread but thought It may be worthwhile putting it in the tool section. I didn't have the proper tool for squishing the master link pins on my new cam chain so I swung by princess auto and grabbed their large nut splitter tool. I used a cut off wheel to remove one side...

Hey guys. Sort of a 2 part problem. First off I seem to be missing a part on my cam chain tensioner assembly. As per the parts diagram in my hanes manual it lists a spring seat or "dampener" as Ive seen it discussed in other threads. Its part number 21 in the diagram below. Is this just a...

Hey guys, so ran into a problem tonight installing my new big bore cylinder into my engine. Previous to installing the pistons I dry fit my heiden tuning big bore cylinders onto my bottom end to confirm it fit nice and flat with no binding anywhere, all was good. Installed the base gasket, the...

I've got a 74 tx650 with 34mm forks, version without top out springs. From my reading it looks like I can add them no problem, finding them more so of a problem. Any body have any kicking around? I've measured the location where they live and the spring would need to be around an inch wide and...

I know this topic is discussed at length in other threads, how to properly seal the base gasket on these engines. However through my searching and reading through the threads I haven't been able to get a clear answer on this particular question. I've purchased the heiden tuning complete 750 kit...

Hey all, I ordered some of the rubber fork dust wiper boots from 650 cental but they dont seem to snap securely into the grooves on the fork body's. If I jounce the front forks a couple times they usually pop off and stay on up on the fork tubes. Any body run into this? Any thoughts on making...

Looks like I may have created myself a problem here. When I started rebuilding my engine I planned on leaving it stock, I ordered this pamco ignition kit from mikes https://www.mikesxs.net/product/14-0917.html Down the road a bit I decided to send my crank to Hugh for a rephase. Now my...

Looking for a complete cylinder head to fit a 1974 xs650. Needs to be in working order. Let me know!

Hello! Just spent some time reading past threads but haven't really come up with a solid opinion on where to source replacement valves. I've got a pair of intakes with excessive wobble in the head area so looking for replacements. Found a couple threads saying mikes ss replacement are...

Greetings all. A couple years ago my father in law showed me a dirty old bike under a tarp in his garage. I honestly paid it little attention at first. The sissy bar and broken glass windjammer didn't inspire me much so I filed in my mind as "neat" and carried on. Some time passed at do to...
