Fuel injectors.

#1 PostAuthor: Gyesdad » Thu Nov 14, 2019 5:31 pm

Gents,
Can anyone tell me whether the injectors on the GPz1100B1/B2 and the ZX1100A are the same or different?
Thanks in advance.

Gary.

The injectors on the ZX1100A’s have part No 49033-1001
According to the CMS website https://www.cmsnl.com/products/injector-fuel_490331001/ this part was fitted to KZ1000G1, KZ1100B1/2 and all the ZX1100A’s
A2 1979-80. A1 1980-now

Not cheap are they ! (I presume that price is for 1, not a set of 4)
I've often thought it might be nice to have a go at restoring a fuel-injected bike, but now I'm not so sure.

Holy crap, 318 euros per injector, a set of Mikuni flat slides is a lot cheaper than that, if you want CV carbs Z1000J ones fit, if you want modern CV carbs I think Suzuki GSXR/Bandit ones fit with a firm push (the spacing is slightly different)

I've got a few spare sets.

If you've got the original ones and you think they might be blocked get a car garage to run them through a bosch injector cleaner.

I had the injectors off my GSX14 cleaned and refurb by these guys. Found them to be bang on. They supplied a graph of before and after performace of th injectors and also gave me new filters and 'o' rings. They were fast on turnaround and cheap too

Thanks gents.
I've used Injectortune in the past for my 1100 Uni and found them to be spot on.
I have a spare set of injectors, I was recently looking at a B1 that was on carbs and wondered if they'd fit but it's been sold.
