Fitted mine yesterday onto the ZRX400.
Total time: under an hour
OK, like most opened the box and went - Oh fook!! Thankfully I used to do a lot of model building so it didn't get thrusted into the back of the cupboard for a rainy day lol
The written instructions burst my head within about 5 mins of reading ( I generally find if something has illustrations that's what i use).
1st Tip:
Assemble the feed head in the comfort of your home - that way you wont loose any of the small parts.
I done the teacup trick with the cable tie then assembled all the parts - pretty straight forward just looking at the pic's
Ensure you have the head the right way up (as pictured)
Delivery tube has a larger gauge nylon tube placed onto it and this is then inserted into the delivery chamber tube. I later read that they recommend you lube these parts for easy assembly but i didn't and had no problem fitting.
The feed tube coming out of the bottle is also placed into the delivery chamber tube and held in place with the crimp washer supplied, again no great problem fitting ( I fed the feed tube through the washer 1st then placed the tube into the delivery chamber and sqeezed the delivery chamber tube to allow the crimp washer to fit on.
Delivery chamber assembled
I didn't bother bending the wire cradle until I was outside with it and saw what I needed to do for fitting onto my arm.
It still didn't make it any easier
I've used Blue ties here but will replace with some chrome ones later, ties on the delivery tube are loose fit.
Here is the delivery head pointing downward with the arms onto either side of the sprocket.
Top Tip: Ensure you get the centering of the head in align with the sprocket as i am having problems with the outer arm coming off

I also think i have kept the head to far away from the sprocket and if it was positioned closer this may not be such a critical problem.
I positioned the bottle for ;
a) easy filling
b) short as possible delivery tube
I was thinking of the frame rail nearer the chain guard but thought my own or passenger foot could cause problems and as i discovered where i did put it is ideal as:
c) able to lube chain on the move
This time I have used 10W30 oil but will be going for something a bit thicker as it does pour very easily.
I also wont be lubing the chain stationary as you just end up with a pool of oil under your sprocket on the ground.
On the move I can easily give the bottle a gentle squeeze and when stopped up i can confirm that the complete chain was wet
So every day use it will get a squirt when I head off and on a run maybe every 100 miles or so. If I get caught in rain I can also decide how often I want to top it up
Just now I am certainly happy with it and as soon as i resolve the head alignment / delivery arm problem i will be delighted with it
