I would say more than likely those are Dynojet mains, stock Keihin mains are 155's. Dynojet has their own sizing system so unless you know the conversion it's hard to tell what they are compared to Keihin mains.

Stock jet size
Hi all. I just picked up a used 1999 ZX9 and it was wrecked. While cleaning the bike up and removing damaged parts I went ahead and checked the valves and the carbs. I noticed that the needles were adjustable. So I took the bowls off and found 134 size mains in it. The jets don't have 'DJ' or 'Factory' stamped on them so I don't know if these are just the stock jets or not. I also have no idea if it is an Ivan's jet kit since I don't know much about those. The slides to not appear drilled. The jets have no other marks on them other than the numer 134 stamped on it.
So, if anyone has a service manual or a stock set of jets laying around, can you check the size of the mains for this particular model and reply what size they are? Thanks.

All of the Dyno jet kits I've seen have the little 'dj' stamped into their jets but I have to admit that it's been a longtime since I last messed with a Dynojet kit.
Does K&N use the same jets as the Dynojet since those kits are basically Dynojet kits re-labeled?
Thanks for hte feedback.

I printed out the Dynojet instructions and it's a Dynojet kit. The slides weren't drilled but some air jet orifices were pressed in.
