What he said.
Jim has a great product. Great support too. Happy me.
I think that Brit bikes ought to have Brit parts on them. AND, I believe that the concentrics are very good carbs - especially with changes in altitude. Their circuit design and flow are better than a VM Mikuni and the smoothbore monoblocs are even better than the concentrics. There were Amal engineers, now long dead, who really knew what they were doing.
So, it was hard for me to walk away from the Amals but the Keihins have a great reputation and frankly, I've been irritated for 30 years with the bean counters at Amal who decided to cheapen the product by selling a zinc slide in a zinc body. Now, after 35 years of wrecking the company's reputation with that zinc slide, Amal finally decides to sell an anodized aluminum or a hard chromed brass slide for your Amal, well that's great. Long overdue.
Now, they sell NEW Amals too. That's great too, and at a nice price BUT not with a proper chrome or aluminum slide. NOOO, you can buy a new set of Amals but if you want slides that will actually last more than a few thousand miles, well, you have to buy them separately ?!??!??!
And, while I'm ranting, what's up with the MK2s? or the smooth bore MK2s? Why did those great carbs go away? Sheesh.
