Trigger, where do I find number stamps? Can't see anything on one of the carbs I removed!
Just by the port screw
So, I now have 2 x '086A', which came with the bike and are on cyls 2 and 3. My replacements were 2 x '657B'. They are on cyls 1 and 4. If I've got the same jets and needles across all 4, should I be ok?
I've done over 500 miles with them so far. Cyl 4 seems to be running spot on (perfect spark plug). Cyl 1 is a bit sooty though, but I was thinking this is due to my head leak, which I'm aiming to fix this winter. I could go with the 657B carbs on all 4, but the two 086As I swapped out, are beyond redemption. Any knowhow on what the difference is between the two sets of carbs?
