Two issues-carb synch/pilot fuel screws

Some carbs have a "master" carb that can't be adjusted. You adjust the others to it! Don't know about 650 carbs but would assume they are a lot like 1000's in design. Also, what plugs are you running? Too cold a plug can be a real headache too.

Master carb ???? Please explain.

Some carbs have a certain carb that is "locked" in as far as adjustability. When you try to synchronize your carbs, you will notice one won't be able to be adjusted or might not even have the necessary adjusting points. Look at your guages and set your other carbs to match the settings for that carb. You basically are adjusting only three carbs. You can find which one that is by trying to adjust each carb...you will find the "locked" one. I believe it will be either #2 or #3, but not sure. Your manual should tell you which one if you have a manual. This of course is for the adjustment of the slides. You can change the jets as much as you want on all carbs.

If your bike is stock then I would stay with the #15 pilots, 102.5 mains and I would put the clip back in the middle slot.
The ignition systems on these bikes are their weakest links. I switched to a Dyna S and Green Dyna coils years ago. They made a HUGE difference in performance and staying in tune. My bike would never stay in tune with old points ignition.

You are right. Aftermarket coils and ignitions are MUCH better then stock set-ups. If you can, switching to these is a very smart move. Technology marches on and electronic ignitions are the way to go. I've seen them "wake up" a bike...makes it feel like an entirely different bike.

Thank you for the info.
I am just trying to learn so am still a little curious.
I was under the impression that this adjustment was for the throtle plates.
I am using BS34's and thought that the needle was controlled by vacumn and adjusted by raising and lowering to a different notch. When you say adjusting slides are you talking about different carburators?

Yep...I am talking about round slide carbs like the kind that came stock of many of the KZ model bikes. On CV type carbs, vacuum raises and lowers the slides with a diaphram set-up. Those I don't have any experience with. I thought you were talking about the older, stock carbs that came on KZ models and many others. I would think that by raising the needle up it would richen the mixture beings it would be uncovering the jet sooner and because of the taper of the needle, more. I've heard some guys would space it up by putting different thickness washers in there somewhere to space the needle up if it doesn't have clip grooves on the top of the needle. I know there has to be someone on here that knows more about these carbs...hopefully, they will chime in here for ya.

"the Fish" - The word is "touted" not toted. If you feel I have promoted my business interests by providing free advice which generates good will, I believe there is absolutely nothing wrong with that. In fact, it is good business practice.

On the other hand, if you feel I have advertised my carburetor rebuilding and sales business in any way, please take examples to Stein, the board owner. I am sure this is against the rules and I have done my best to NEVER violate these rules.

Last, my signature is allowed to contain a link to my "wiredgeorge Motorcycle Carburetors" web site since it doesn't make reference to the business or indicate any sort of a solitication otherwise.

In ALL my advice, I have told folks HOW to do their own work which, in actuality, probably causes me to lose business. In addition, I have ALWAYS freely pointed out when I thought a problem with a bike was electrical or engine related and not carburetor related; both on this board and in private.

Anyway, God bless Canada and our unhappy brothers to the north. Contact Stein with complaints, because as one of his moderators, I suppose I had best quit replying to any of this as it can only make me appear silly. Cheers!

Thanks for the no charge spelling lesson.

The rules learly state that " product or service advertising is stricly prohibited". It is rule #1.

Heres a post wehere you clearly solicit carb repair sales instead of giving free online help

and I'll quote

Send some money and the carburetors and just like magic, the carburetors will show up on your door step a few weeks later... they will work properly and the little annoying holes will all be fixed hehe Dang, since we shipped you off to Okiehomer, you have lost all sense bwhahahaha

You say you do your best to never violate the rules, but you clearly break them to solicit business.
