I have been having a conversation with Roberto in Italy who is working on his carb. His bike is an Italian Gen 1. He asked about an extra hole in his slide, so I asked him to send me a picture, as it sounded like it might be a LAMS hole.
But it isn't a LAMs hole, and it has me somewhat baffled. I wonder if anyone else has run across this. The pictures he sent me were a bit fuzzy, so we found some on the Italian e-bay site.
Here's Roberto's slide. He says the transfer hole (the one we would drill to 7/64") is between 3 and 3.5mm. He tells me that it came that way.
This is the slide for a KLXR.
This is the slide for a KLXC.
This is the slide for a KLR.
The transfer hole on Roberto's is larger than what we would drill, as we believe it would cause slide flutter to drill it out larger than 7/64". The additional hole on the KLXC and KLR make for a hole way larger than what we would consider feasible and the hole on the KLXR just looks friggin' huge.
I am not sure what else would be going on to accommodate these large holes and what the purpose of such large holes would be.
I'm off to look at the inside of a slide to see if there is any clue in the casting.
