What kind of mileage do ya get?

:laughing7: if you look at the disign of a dynojet needle appossed to a standard kawasaki needle the difference is strikingley clear

the standard needles used by kawasaki are a compromise so the needle is slightly tapered ans has a sharp point at the bottom a good allround compromise

dunojet on the other hand are just a very long taper which go from top to pointed tip in one go this gives instant throttel responce which gives better acceleration so less time accelerating = better fuel economy the fact that the needles are tappered all the way down means you dont have to open the throttel a long way so again you dont get a sudden rush of fuel just a constant flow

you can fit a stage one djnojet kit to a standard air box standard exhaust standrad muffelers

a K&N direct replacement filter give better air fuel atomisation

my fuel figuers were just standard riding up and down the box and verious speed limits 30 40 50 and 70 on the motorway

will be doing a 255 mile round trip at motorway milage (70 in uk) will report back:thumbsup::thumbsup::thumbsup:
 
Interesting....

It is hard for me to remember but I think when I first bought my 900 I think I was getting 55 miles until reserve and with it being new to me, I was probably riding it a bit on the aggressive side...When I bought the 900 it had a stage 3 jet kit in it, pods, and the Cobra mufflers...I am pretty sure the bike has an advancer on it too...I put the airbox back on and put carbs back to stock and now have stock mufflers....Maybe I will buy a dynojet kit and put it at stage 1. I have a K&N replacement filter that I bought but I don't have it in yet...

I tried turning my mixture screws in to 1.5 turns and my head pipes started to discolor (lean) so I put them back to 2 turns out...I have a set of dyna coils for it too...Just gotta find time to do it all...Cam chain, guides and tensioner are gonna be replaced too (rattling)...

:nono: if the bike had individual filters on (pods) and youve put the standard air box back in you will need to replace the main jets

take out the stage three jets should be 36 jets and replace them with the stage one jets should be 26 jets this should then give you better mpg as the bike will be running to rich :hello::hello:
 
Let me clarify...

When I got the bike it had pods, stage 3 jet kit and cobra mufflers...The cobra's are slip-ons and the power chamber was still on the bike...With the pods you have increased air flow...The larger mains were in the carbs. The starting of the bike cold was terrible...I sent the carbs to Rick. He pulled out the stage 3 and put the carbs back to stock except for the mains which he put in 135 mains....(because of the pods)...I would get (if I remember correctly) about 55 miles before going to reserve...

I eventually went back to a stock air box with a paper filter. I put slightly larger than stock mains in because of the cobra's. I either put 127.5 or 130 mains in....

From your post I got to thinking that maybe I should buy a dynojet kit and put in the stage 1...Except I would not drill the air lift hole in the diaphram slides...I have a K&N direct replacement filter to put in too...

I know I cannot put stage 3 with factory airbox and stock exhaust...
 
if you get the kit their will be a slider drill in the kit so you can see if the holes have been drilled

if you fit the kit springs i would advis drilling the slides or you will defete the object
 
of course you could take off the power chamber as this will act as a restrictor

my streight through turn outs are fitted ater the link pipe but the power chamber is removed :hello2:
 
Other day was real nice, decided to take an hour ride and ended up putting 160+ miles on the bike. was gone all afternoon coming home at dinner time.

Had a blast. To make a long story short, I got over 41MPG both ways and the bike rode great.

This was in my stock 85ZL900.

All this was on country roads with speeds between 40 and 70MPH.

Nice. 41 is about the best that I can get lately. most of the time I get 34 but
once in a while I get 38 39 40, I am beginning to think that the lower MPH
might be due to evaporation because it seems like when my bike sits for a week without being ridden and I ride and then fill it up and check the mileage, it is in the lower range.
 
Sitting does not seem to effect my bike, although as the carbs get dirty and need to be cleaned miilage does suffer.

I'm the second owner and have had the bike 15 or 16 years, forget exactly but a long time.

When I first got it I had the carbs cleaned and set and got 40+ MPG.

I noticed in the last few years it was not that good.

Now after having the carbs cleaned again (one primary jet was clogged anouther barely functional) the milage is back up to 40+ again.

Anyhow I'm really pleased with the way it runs and the gas milage.

On a side note I have one of those I-phones and when I get close to reserve on a long ride I tell it to search for gas, it's real handy for finding the closest station.
 
I have to ask, did you get that bike from Willy?:winkcool:

Sorry willy but thats funny!:rotf:

Bacchus my brother-in law managed 36mpg with my zl on sat 2 tanks back to back and he is just learning to ride and dosent really know shift points yet. Gotta ask what are you guys doing, cruising around in the wrong gears all day or what?

26mpg is what I get when I play real hard and keep the throttle wide open threw most of a tank of gass.
 
carbs are bone stock, not so much as a washer on a needle.....125 stock mains....#35 stock pilot jets .....the works.....jetting for this bike would help I'm sure
 
All this talk of gas milage is fun, but the real reason we own these ZLs is for performance!!!!

I figure if the bike is a strong runner and I get acceptable milage I'm happy as a clam at high tide, and you all know what a clam does at high tide.
 
no trailor mark....

not whooping up on the bike too much, just average to moderately agressive uruban riding. I do like to punch it a bit off the line but otherwise not wraping it out real hard. my zl1000 gets 32-34mpg under same riding conditions. carbs are freshly serviced by Rick and bike runs good. Im in phoenix so this is flat-land riding
 
:laughing7::laughing7::laughing7::laughing7:

One of these days I am gonna get to the bottom of my mileage problem...

I can cruise at 60 mph in 6th gear with no wind, flat ground, and I will not get any better than 25 mpg....Average riding with barely getting in the throttle gives me about 22-23....Goin balls out...20-21ish....

I would jump for joy if I got 30 on the highway...
 
Im trying to understand how smaller carbs with smaller mains would use more fuel per mile????

mine is set up as it would have rolled off the show room floor in '85, so as far as Im concerned bone stock baseline is around 26mpg for a zl9.
 
I guess my big thing is I hear so many guys talking about getting 35+ mpg and I am getting 10 mpg less I think "somethin aint right here"....My carb set-up has gone from completely bone stock to experimenting with main size to shimming needles...all of that gives me the same result...valve adj should be right in line (I did it about a year ago and don't have a ton of miles on it since)...As far as internally, I am not sure...I know it needs camchain and tens and guides....

I got about 28 on my 1K, but I have found several things that I believe were affecting that...I just want them to be in the ballpark and run well..
