NRP specialise in carburettor diaphragms, air cut-off valves [or coaster enrichment valves] carburettor overhaul kits and spares for all Japanese carbs. NRP manufacture and supply a large range of main diaphragms for Honda, Kawasaki, Suzuki, Yamaha, Triumph, Aprilia, Benneli, Bimota, Beta, Cagiva, Ducati and Sachs motorcycles, as well as Vespa, Hyosung, and other scooters, only available from us.
We have been producing diaphragms since 1988, and take pride in not being constrained by genuine part supply. We are the only source of many discontinued parts for older models, at much more reasonable prices. We cover Mikuni, Keihin, Hitachi, Tokei and TK Kikaki carbs from 1970's to 00. Where as an original part the diaphragm is only available as a complete sealed unit, we offer a service where we refit a new diaphragm to your original slide.

This is a somewhat belated review,as the experience dates from around 9 months ago....
Having looked at the NRP website,and noted that 'stock' was carried for a set of Keyster premium carburettor kits for a '78 Z650 C2,I promptly completed the purchase of a set of 4 kits and awaited the 'first class' delivery,as quoted..
However,3 days later,the kits hadn't arrived,and I decided to telephone and find out when delivery could be anticipated.
Having spoken to an employee of the company,I was informed that 'we are currently out of stock,and will be getting some more in in a couple of weeks....'

Think again when dealing with NRP.
Horrible service. I received an incorrect item, I mentioned this to NRP who instantly replied telling me that I was wrong and that I could not return or swap the item.
After dozens of attempts calling and being hung up I finally get through on the phone by calling on a private number, to request a refund which was blindly refused before they hung the phone up on me yet again.
I called back only to be told repeatedly with considerable attitude "we will write to you via email" while ignoring my questions. Needless to say they didn't write... I do not appreciate

Not impressed at all.
I am still waiting for 2 diaphragms that I sent to be refited 8 weeks ago.
Call them 3 times to ask about the progress with 2 weeks intervals and still no concrete reason for the delay (waiting on parts from the supplier, come on 8 weeks seriously)
I am out by £85.00 and the carburetor sliders.
I expected to get some updates via email like any company does if there are any delays.
I am afraid this company is leaving me in the dark.
Unfortunately still waiting.............
