Stiff fuel tap

[DavidZ1R]

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?

[compo z1r]

in a word YES

[KeithZ1R]

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.

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!!!
