Son of Grenade's engine is still waiting to be bolted together, purely through not having time on my side (and a lawnmower on the bike lift), however interesting snippet here regarding reuse of Buell parts. Nothing new here, but have never seen a photo of these bits together:
S1 Silver 034.jpg
So from left to right, we have:
32402-83 - Trigger rotor for S2, S1, M2 and early S3s
32422-98 - Trigger rotor for X1 and late S3s
32473-02 - Trigger rotor for 03 to 07 XBs
Something to note is the difference in keyway position between the 32422-98 and 32473-02. I always believed this to be 90 degrees but in actual fact it is more... This is due to the position of the keyway on the crank driven cam, which changed on the XB and is the reason why you can't just bolt an early trigger rotor on an XB to run with a carb, see this
post... And before you ask, the Cam Position Sensor does not have enough movement...
But, if you wanted to run with XB cams in an X1 (same as Screaming Eagle "E" grind with a whopping 0.551" of lift - but reading here
they don't perform as well as the 0.536"s which have a longer duration - also the timing marks are in the wrong place cos the front and rear inlet cams are swapped), you would need to use an XB trigger rotor.
If you wanted to run the sweet performing SE 0.497 (standard in S1, S3, M2, X1) on an XB, you would need the X1/S3 timing rotor (which is no longer available, although the big blue bird that lives on the shore of the Tame carries stock) and also work out the timing - although word has it that cam sets bought now have Vs for XB timing and Os for tuber timing.
