Excellent observation. I suspect that rev potential will also be similar.

Incidentally, I really like the stainless steel, exhaust header on the AJP PR5 motorcycle. Besides the
material and shape of the header, I also like the location of the O2 sensor bung.

I'm wondering the same thing. I suspect that a connection will be made at the diagnostic port, much like you'd do with an OBDII system.

After watching some of the Dobeck videos, I am very impressed with the engineering talent and manufacturing capabilities of their operation.

The track for the Idaho Backcountry Discovery Route has just been posted. With a length of 1,250 miles, this is an epic route.

It's the longest BDR yet. I think one would have to budget 14 days to make the loop. I know for a fact it's a beautiful ride.

Indeed, that is an intelligent observation.

You know your engines, sir. Of course, you are correct; it is a 4.3 liter, V6 engine.

Perhaps they bifurcate the cable leading from the wideband O2 sensor, and add an extra connector for the AFR+ controller.

Yes, Zongshen committed to a January 25 deadline for the first shipment.

Might we expect the Los Angeles Times to print an upcoming review of the Zongshen RX3? Check out the CSC blog.

That story was very funny! It wasn't long before I got lost in that blog, scrolling down over the last several posts.

That story was funny. Joe is a good writer, and an even better photographer.
