another one bites the dust
« on: November 30, 2025, 08:40:35 AM »
allens performance UK, supplier of all things carbs shuts down.

Bought from them only once eons ago, all was ok, but seemingly not the case for others.

Still, after losing also Sudco last year, it's getting more difficult to get carb parts

Have to wonder where did the stock of both companies ended up...

Really bad.
I was lucky to find their webpage where parts could be ordered. It was not that easy to find it.

Found correct needles for my Mikuni TMR 32  3 years ago. The last 4.

I saw other good to have parts.
Good prices and quick shipping.

I hope the late golden era for our old bikes can continue for a while more.

Good idea to buy while parts still are available.

  There are a few items that I waited to buy and now it seems to be too late. I'm wondering about the kibblewhite engine parts for our bikes. The CycleX web site is missing a few parts these days.

I tried to buy some carb adapters from them.  I gave up after they shipped them to the wrong country 2 times, and had to fight to get a refund.

I have sets of Kibblewhite 33.5mm OS intake valves Don. They have been discontinued by Kibblewhite for a while now.

 I was going to finally order the beehive springs for the F2 head, looks like I waited too long.

That’s a shame I have used them for many years , when it changed hands some people had problems but I never had any complaints .

That worries me. I have a good head with Kibblewhite 33.5/28.5mm valves on my K6.
It might work for 5-10 years more. But who knows? 
I'll regret not buying replacements while I could.

Simon, with your connections, any chance of finding out where all the material ended up?
