That's a lot cheaper than other places I've seen. lha

just recieved these diaphrams and they look great, cant wait to see if this cures the hanging idle problem, also got some new rubber carb holders!

That's awesome!! So cheap!! I thought id be stuck having to buy the super expensive ones from MikesXS. Good find.

So did it ever cure your idle hang? I'm havin the same problem and my diaphragms are the only thing left to blame.

yes, i would highly recommend these if you have any suspicion with your carbs at all.

look at my build thread for a more in depth review

Just received some of those diaphragms, and I'm very happy. Fixed my idle hang, and before my bike would die at idle, and now it doesn't. Highly recommended. Thanks for sharing your find fubar!

I know this is an old thread but I am glad to have to found it.
