So my FZS 600 carb to head rubbers were absolutely cracked to hell and sucking unmetered air in after the carbs, making it run lean and lumpy.
I proceeded to buy a set of cheap new ones on eBay, and when they came one I noticed the part numbers seemed to be sided (two had L two had R... seems simple?)
Now this job is one of the most fiddly I had ever done due to the fact I just loosened the air box and clips on the carb fronts and slid the lot back giving me about 15 mm of room, and the inner two sets of bolts were an absolute fcuking nightmare to reach!
Once I got the old ones off I swapped over the clips etc and noticed that the part numbers on my new ones were labelled opposite (the L was on the matching right pair and the R was on the matching left pair )
But everything else matched so I crossed my fingers and fitted them L to right side and R to left side, half expecting it to be wrong somehow and having to redo the job again!!!
Luckily when all was refitted, I’d made the right choice and it went back together great!!
So glad I did this job too as one of the inner rubbers has been fitted wrong previously with the lip being pushed in and the clip fastened over it-this must have been running quite lean on this cylinder so I may have gotten lucky!
All in all glad to be finished and hoping she rides a bit better next time I’m out!
Included a few pics of the old rubbers and the difference in part numbers between two matching ones (new and old)
