Re: Carbs, bloody carbs

hi Guys, I’m working on my Z650F3 carbs and the manual says float height is 18.5mm in the Clymer supplement for later model section. However it isn’t clear as to where this dimension is set on the float itself. There is a flat portion where the hinge arm connects and then a step down to the curved ...

Re: Z1000A1 Main jets with Kerker

What main are you on now.
Shouldn't need to go up more than one size with just a pipe change especially with the stock airbox.
May not even need to change it at all depending on the flow of the pipe.

Most yrs jerry struggles to fill the stand so grabs the offers soon as only saying Phil Yep! same every year which is why i've had at least one or more of my bikes on the stand as backup every year for the past few.

Re: KZ1000 carbs

Unless there is physical damage , float posts broken off, stripped air screw threads etc I've never had a set of carbs that are actually worn out.
The only non replaceable wearing area of the actual body is the slide bore and I've never had a carb become unusable because of that.

Re: Will this fit my Z1R

Can't help with the part numbers as i'm currently away from the workshop but the D1 crank takes the same bearings as all Z1, Z900, Z1000 through to Z1R D1. The D2 , ST and MK2 all use the later "Square cam cover" motor that uses a beefier crank and slightly different bearings. I suspect th...

Re: Pilot Jets...

Air screws in all the way means that you are enrichening the pilot circuit so larger pilots would be the obvious way to go and 17.5 would be where to start but the cutting out and lumpy running is more likely to be blocked or partially blocked pilot outlet passages so that would be the area to check...

Re: spark plugs

Have never had any trouble with NGK's or the Denso iridiums. I've had the same set of NGK's in my Z1R for 15 years or more and only recently changed them as part of a good going over for a 2000 mile round trip to Portugal but the new ones made no difference. I've got 8 Denso's in the twin plugged Dr...

Re: Greetings from Mallorca.

Average stock cam chain life is around 40k miles. This is presuming the motor has been looked after and correct tension maintained. A new one can be fitted without splitting the motor and using a rivet link which is perfectly fine if done correctly but if the chain is worn out then the rest of the c...

Re: Cam chain assy needed

Done right the motor will last for years and the initial expense will more than pay for itself.
I'm 20 years in on my Z1R since the last proper rebuild and it's still a strong motor.
This is my true everyday ride that's done a couple of hundred thousand miles not a show pony.

Re: Cam chain assy needed

You will need to buy new as any used stuff will most likely be on it's last legs. Go for PMC or Liska stuff on the idler sprockets and mounts as it's cheaper then OEM and eliminates the rubber which degrades on the stock idler sprockets so will last virtually forever. The lower rubber wheel and fron...

Re: Replacement Cam Chain

Tsubaki stopped selling the HD camellia cam chains for the Zeds a while ago but you can still find the odd one on ebay. APE now supply an equivalent HD which is what I would buy.( probably still made by Tsubaki for all I know and cut and packaged at APE.) As for longevity i have HD ones in all my Ze...

1000J carbs as a last resort.
VM28's will work well with the engine spec you have.

Re: Amsoil

Generally speaking don't use fully synth in these motors unless it's formulated for roller cranks. I use Rock oil TRM 20/60 in my tuned motors but for stock stuff it would be a waste and any decent 10/40 semi is more than good enough. Lots of stories of slipping clutches, oil leaks and excessive exh...

Re: Z900 stumble just off idle

I think Allens performance should sell the pilots or someone on the forum may have the size you will need.
Apart from getting blocked they don't wear out so s/h ones will be good enough.

Re: Z900 stumble just off idle

Ride the bike and feather the choke at the flat spot to see if that smooths it out. Do it in a high gear 4th/5th as this is where you will feel the difference. If it does you are still slightly lean coming off the pilot and richening on the air screw by 1/8 to 1/4 turn should do the trick. You could...
