Ant help here, the fuel tap on my Z1R is so stiff to turn, worried I might snap the lever at times, cleaned it out last week, put on new O ring put a touch of grease on the O ring put back together, fine nice and smooth, week gone by stiff to turn again? is it the modern fuel?

in a word YES

try backing the holding/guide screw a wee bit see if that helps

I think not fuel,

My original (1975) Z1 fuel tap was a little stiff to turn up to reserve setting but ok between on and off.

Fitted new genuine fuel tap - much smoother action between all positions.

Fuel did not change.

Conclusion - it's a wear thing. Will monitor and see how long new one takes to go stiff.

i thinks so lead was a wonderfull lube bring back 4 star

have you checked the condition of the screw that holds the lever to the tap as this normally wears + causes the lever to sit slightly of centre + bind on the outer edge of the tap

For my Z1r, I have owned 2 fuel tanks for years -
Sometimes I use the smaller tank, as I prefer the appearance - and sometimes I fit the larger tank - usually for longer journeys.

The fuel tap on the smaller 3.1 gallon tank has, from new, always been a swine to turn.
The smaller tank also has a physically smaller tap which exaggerates the problem, as it gives you less leverage.

The larger 4.5 gallon fuel tank (which I am currently using) has always been silky smooth in operation. This is my most 'recent' tank which I have had since 1987.

I always thought this issue was just inherent in the small tank tap design.

This may or may not help but could it possibly be the O ring not be made of the correct material and the ethanol has made it expand? Food for thought.

Had this problem when I first got my Z1a. Fitted a new tap 10 years ago. No problems since. Its probably worn out. As far as the o rings go if the part is the wrong rubber it will swell in fuel.

A pingel will sort all the problems out

+ 1, fit a pingel and forget about it.

Fitted a Pingel HiFlow on my Z650.
What a beautifully made piece of kit!
Definately improved performance too.
Go for it!!!
