frankd Posted August 20, 2012 #1 Posted August 20, 2012 (edited) I was installing my JBM carb diaphragms, and I got a little to energetic getting the metal ring out and a carb slide broke apart. Anybody have one that I can buy? The condition of the diaphragm isn't important, I've got the new one to install. It's for a 1st Gen, MK II (89). Thanks, Frank D. Edited August 20, 2012 by frankd
saddlebum Posted August 20, 2012 #2 Posted August 20, 2012 (edited) Sorry about your predicament, but why did you try to pull the metal ring out ? To get the plastic rings off, you simply nip them in half with a pair of wire cutters and then to install the diaphrams you simply gently stretch them over the lip of the metal sleeve. Just don't over strecth them. see the instruction sheet http://jbmindustries.com/Yamaha650.html Edited August 20, 2012 by saddlebum
frankd Posted August 20, 2012 Author #3 Posted August 20, 2012 It does say that for most carbs, but for the Venture, the website has an additional instruction. Yamaha Venture Notes: The 73 mm Mikuni Diaphragm fits the Venture models even with plastic slides. Remove the short metal tube from the plastic slide and remove the rings. Place the JBM Industries diaphragm on the metal tube, and then push tube into the plastic slide. Use Super Glue on metal tube. Frank
KIC Posted August 20, 2012 #4 Posted August 20, 2012 I just used some silicone spray and a credit card to slide them on. Didn't remove or replace the plastic ring things.
raybear71 Posted August 20, 2012 #5 Posted August 20, 2012 Are MK1 and MK2 different? I have some from an 83. If they are the same I will drop one in the mail for you.
frankd Posted August 20, 2012 Author #6 Posted August 20, 2012 Yes, according to Yamaha part numbers, they are different. Thanks for your offer though Frank
MiCarl Posted August 20, 2012 #7 Posted August 20, 2012 If you strike out, I sell new aftermarket slides (with diaphragm). Takes me about a week to get them. LINK TO MKII SLIDE IN MY STORE.

Frank I read that too but at the time I felt it much safer, to just cut the nylon rings and leave the metal tubes in place, popping the diaphrams over the lip. worked very well that way, with much less fuss.
