Well, it looks like the Buell is down for a few days. I was riding in the HOV lane on my way to work Tuesday morning, crusing at about 75mph. The engine all of a sudden rev'd up like the clutch went(my first thought) After pulling over and inspecting the bike the front belt pulley was completely stripped in the middle with the shaft just spinning. The previous Sunday I ran it pretty hard up in the mountains here outside of Seattle with my buddy and his 1999 Ducati 748. I am happy with the 27 tooth pulley's gearing. But have been thinking about putting on a 26 tooth. Any suggestions or experience changing the pulley would be great! Keep those tubers alive!!!! | ||

The 26 tooth will give you a little better edge on shot straight aways against the DUCK ... Just make sure you install and torque the sprocket nut correctly ... | ||

The shaft splines still good? That's amazing. Was the pulley a stock part? There's a gearing chart around here somewhere that gives the difference in speeds at different rpms (or was it the other way around.) You have to consider rpm at your "cruising speed" of 75mph. It will go up like a few hundred rpm. | ||

It is pretty common for the soft cast iron pulley splines to fret away into powder. Happened on my '96 S1. It was a surprise discovery. The friction from the nut holding the pulley on was enough to transfer full engine torque. I didn't even know the internal spline teeth were gone until I removed the pulley. Non-lubricated splines have a tendency to destroy themselves in this way. Thankfully the shaft is significantly harder than the pulley and doesn't wear out. |
