Fitting Buell XB cams .551 E grind to XL

With envy.

I dont see how its bragging when it is just backing up this thread that it is possible to install inexpensive Buell XB cams into a sportster?

I would agree. Seems like some people are just gutless pussies who hide behind anonymous e-mails.

thanks for your post and the helpful explanations on how to do it.

So I might be about 3 years too late for this but I believe his #1 and #4 cams need to be swapped. I just bought some XB cams for my 2006 and I'm using this pic for reference but the timing marks just don't add up like mine do. On mine the #4 cam has the dot right next to the "E" like his #1 cam shows.

Good thing he used a degree wheel to time it though.

Buell cams spin backwards than a sportster, so swapping 1 and 4 is necessary.

Bike still runs great, don't own it anymore but know who does. I still have my build photos if you need any reference.

Yes, but I'd put money on your current cams being 4,2,3,1 from left to right. Like I said, my #4 looks just like the cam you've got in the #1 position. And I'm not talking about the cam position as #4 either, the cam itself actually says 4E on the lobe.

Regardless, if you used a degree wheel you can make them work like they are. From the looks of the timing marks on 2 and 3, it worked.

I know this is older, but since Matt posted a month ago, I figured I would update. I have re-timed a lot of XB cams, as has Chad Hart. The 1 and 4 cam do not need to be swapped, but it can be done, as the cams are identical except for the marks. Some people swap them so that the only mark seen during install is the new, corrected mark, since the #1 cam has the stock mark up on the smaller circle rather than the gear, and the #4 cam on the gear instead of the smaller circle. This is a nice, clean way to do it, but not necessary. When doing so, I do also recommend scoring new cam numbers on the gears so you or the next person don't get them mixed up during swapping or reassembly.

This is old thread but there are no threads like this. So, I post to this thread...

I am planning to put Buell XB E 551 cams to 2001 sportster (rigid or pre-rubbermount). This thread dealt with every other problem (and there were solutiojns), but not the timing cup problem, because it concerns only pre-rubbermount sportsters and everyone in this thread had rubbermount. Aaron still said that cup problem.


Now I don't have tgose cams yet, but I know from pictures that the timing slot is in quite a lot different place, and I have some questions.

Arron remembered it could be somewhat 90 degress off... WEll, does anyone know for sure?


What do you think would be best way to tackle with the issue? Should I make new slot or notch to the cam, or what would you do?

[twinspeed]

Well, I think I'd go to machine shop and take both cams containing the timing cup (original sportster cam and buell E cam) with me.

It Would be probably the best plan to let those to do the work, who have exact machinery and such.



Of course, if there's easier way (not involving costs) to do that, I'm all but ears (and grateful),... If you could just let me know it


I was thinking about modifying ignition module rotor or putting ignitin module to different position. But ignition module is probably such that it could not be moved 90 degree, and that rotor is hard to modify such that it is precisely done.
