Ebay Diaphragms

[Condor]

I contacted the seller of the diapragms on Ebay questioning him about the application of them on the 1stGens as stated in his title. I don't know if anyone has tried to seperate the rubber from the slide, but I find it nearly impossible. This is a copy of our discussion. I'd be very carefull if any of you were thinking about bidding on this auction.

 

 

Are you sure these will fit a XVZ12 XVZ13 VENTURE ROYAL The reason I ask is that, unlike other daiphragms, it's almost impossible to split the rings without damaging them, and the alignment tab on the edge shown in the pic will not fit the recess on the carb body. Comment?? Thanks

 

Hi, well, Herman in the Netherlands, ebay ID storm-h( 72) was my first customer, he had installed these in two bikes, we worked togheter a long time trying to find out if these diaphragm will fit that bike. You may contact Herman for feedback. Regarding the tab you can just cut it off. Hope this helps. Any doubt contact me. Rob

 

Well, that may take care of the tab issue, but I still can see a potential for a developing an air leak as long as the indent remains empty. What it doesn't address is how your friend Herman split the flanges to replace the older membrain as the rings are a press fit, very fragile, and very difficult to seperate with out breaking. If you're lucky you may seperate one out of the four successfully. That's why replacement diaphragms are sold already installed on their plastic slide. Unless you plan on backing up your claim, you may want to post a disclaimer to your application claim, or guarantee they will work, which I know they won't. How do I know that? I've owned a lot of Ventures over the years, and rebuilt a few Venture carb sets during that period. Just a word of advise. I'd suggest rewording your auction title and discription.

 

First I need to thank you for your time and help in this matter, I need to say that I am a honest seller, I has been contacted by a Venture specialist from the Netherlands really interested in these diaphragm after Herman's purchase so at this point after your email I am really confused and unfortunately really ignorant in this matter. Please advise on how I should rewording my auction according your experience in this matter. I don't want to deceive people if these parts will not work and obviouslly I will refund money but at this time I am thinking in cancelling this auction....sincerely. Rob

 

Hi Rob. Perhaps the expert friend in the Netherlands could supply you with pictures of a Venture diaphragm membrain being replaced, like those you've posted in the auction using another diaphragm type?? Perhaps he knows something we don't?? Until then, I'd relist just for the bike the membrain was designed to fit. If you don't absolutely know what it fits then more research is in order. I know it was not designed to fit a Venture when the tab has to be removed.

 

Thanks, I am concerned about al that so just cancelled auction until I can make sure what I am selling, thanks again for your help. Sincerely. rob.

 

Probably best all the way around Rob. Good luck.

 

 

Thanks Jack, I appreciate your comments, awaiting response to them from my experts in the Netherlands. Rob

A LITLE UPDATE

 

I just received an E-mail from Rob the seller and he sent me the response from his friend Herman. Personally I've never had any success removing the diaphragm rubbers as discribed. Maybe it can be done?? Anyone here ever tried it?

 

Goodmorning Rob.

 

I can only tell you about my own expierience with changing the diaphragms.

All four came off pretty easily with a bit of twisting and pulling ( they were busted so there was no need to keep then in one piece ) .

This means that you don't have to split the carb, slides and after a bit of lubrication you can install the new diaphragms, with care ofcourse and that's it.

I think that it all depends on the skills and the patience of the person installing these diaphragms, nomatter what kind of bike you have.

So I think that maybe you should mention a certain amount of mechanical skill or background is needed to make this a succesfull operation.

I hope this provides you with enough information.

 

Take care.

 

Herman

Very interesting condor. If my memory serves me correctly, didn't the 1st set of four diaphragms go for about $160 and that is just for the rubber. We are talking about a bucks worth of material here without the slides being included.

I think it would be great if someone could come up with a way to supply diaphragms at a reasonable price, but I do not think this is the way to go.

Good post, I appreciate you doing it.

you did good, jack.

i'm not sure whether the seller "just didn't know", and was trying to learn from you.or. whether he knew that he'd been caught , and was trying to sound ignorant.

maybe you should have a talk with "Herman".

lol

There is no way that we can know for sure but the seller sounded honest and sincere to me. I will give him the benefit of the doubt.

I was going to order me a set just because it seemed like a very reasonable price. Thanks for the info. Glad I didnt waste any:mo money:.

 

Stay safe and keep the rubber on the road.

I think I asked about the tabs when the first set came up.

Yeah you did Dan. Sharp eyes. Made me go back and look and start asking questions when the next set popped up. I just felt I didn't want any of our guys getting stuck paying big bucks for those things. I like to save as much as the next guy, but I think a few folks didn't know what they were getting into when they bid...
