    First of all, I have searched high and low for close up pics to show the spring placement in the linkage and I feel like I am missing something. I broke a couple of the gas vents when I took the carbs off incorrectly so replaced with aluminum ones and new o-rings for the air vents as well.

    AS you can see in my photos, I have 3 springs that I cannot quite figure out how they go and the pics I took when I was pulling them off werent very good (lesson learned).

    I wouldn't say I am an expert mechanic but feel like I went through the carbs pretty well. The bike has not run in 9 years and I got it from original owner's garage. It has 18xxx and is an 84 tariff beater that I hope to get running before long. I gave the brakes working again and assume I should go ahead and check cams as I have read all about the oil issues on top (no oil mod on this bike). Any advice on that and also if anyone can point me to some closeup pics of carbs so I can figure out how to get these springs in place I would much appreciate it. This is my first time to work on a V4.

    I am not sure why I am having so much trouble posting these pics either-swear they were not upside down when I transferred them?

    I have a spare set off my '83 I can take pictures of. Are you talking about the throttle linkage springs? How old are the rubber boots that hold the carbs on?

    To upload your picture easily, put them in folder or desktop where the can easily be found.

    I took a couple of pics from my manual that may help. The springs are called thrust springs and tend to fly to all kinds of places when least expected. The manual is from and 83 Canadian 750 but I suspect the spring location is the same. Did you check the diaphragms on the carbs? they are delicate when they are new so old ones are probably even more so. IMG_3769.jpg IMG_3770.jpg

    Thanks for reply. The boots are actually in great shape as were the carbs aside from a clogged slow jet and one sticky slide. I would love to see a couple close up pics of your put together carbs where the springs sit connecting the throttle linkage if it isn't too much trouble. The pics that BCAI posted are helpful but it still just doesn't seem to all be holding together right. I guess I need to put the plate back on before bench syncing?

    I ordered new throttle cables from local dealer trying to be supportive and the two day turn around has now become a week and a half so soon as I get those I'm going to start putting it back together and hopefully fire up. Is checking cams something an untrained eye should be able to pull off?

    Also, thx for pic tips. I will do better next time.

    Thank you! I know where the two larger springs go now thanks to your and previous help but in your third photo I think the little spring goes on the side that I can't see in pic and below one of the screws with the spring on it? Going to look for threads on checking cams before I put them back on bike. Thanks again-I was ready to break down and buy a backup set of carbs on eBay but hoping these will work. Next time I'll do a better job during tear down.

    This should show where I need to see a correctly put together set. I can see a spot for the little spring but then cannot figure out how the metal piece fits into it to make it engage as there is a place on top and bottom for little spring to set into...Should I have already attached the plate with top boots to keep it all together?

    Thank you very much! Great pics-going to get them back together tomorrow if kids/wife allow some garage time.

    Got them back together, new aluminum gas tubes, all new o-rings, and gaskets, and benchsynched. Looking for good thread now for checking cams before putting back together. May just go ahead and see how it sounds (if it sounds as it has been 10 years according to original owner).

    Looks good, I replaced all the phillips head screws with allen head cap screws readily available at ACE Hardware. Much better torque and heads don't deform.

    A small spring goes under each plate where a synch screw is located. Test by holding throttle wheel fully open and pushing each throttle plate to check for any individual movement, of which there should be none.
