right, i have 2 YDLS srx carbs here ... both appear to be identical, certainly the diameters are the same (32mm & 30mm)
i have removed the jets, and one pair definitely look larger (hole dia) than the other, so my supposition that these were both off 400's may be wrong, and probably one is off a 600.
i can see no markings on the jets whatsoever.
you are welcome to have both pairs for comparison and, if required use. i'm sure we can come to a mutually agreeable settlement should you want to keep them (they are out of some old carbs that have been robbed for parts over the years and the jets are about the only useful bits left)
if you want them drop me a line with your address
cheers
ps.... i lied! ... with torch and magnifying glass i have foun some markings
carb 1, primary/main (the one on the emulsifier tube) jet 118 . secondary 100
carb2, primary 136 . secondary 100
the mystery is .... on carb 1 both jets appear to be a similar size hole on carb2, again same size hole BUT considerably larger than carb 1, even though both secondary jets carry the same number ... i'm wondering if carb 2 had been subject to some form of tuning, i know dynojet did a kit that involved opening up jets (i think)
anyway, if they are of use.... drop me a line
