So I am getting ready to rejet this Friday and I think i just about understand what needs to be done. Change out the main & pilot jets and adding a washer under the clip of the enrichment needle. Take the brass caps off, tighten them down and then back them out 3 full turns.
Is this it?
What about synchronizing? How is that done????
Please, please, please help :bowdown:
I'd be interested in knowing signs of when you NEED to synchronize.
oddly, there seems to be lots of information for HOW, on the web, but precious little about when.
About the only thing I've found on that seems to suggests;
"(after you change the valves, otherwise almost never)"
Your bike will run smoother after you do it. I did it at about 17,000 miles and it did make a difference. If your bike doesn't feel super smooth, its one thing to try.
Synch it if you get the carbs out - or atleast check it. Usually they hold the synch. And oddly a valve adjustment will throw off a vacuum synch, which is why I dont like it. A eyeball synch isn't affected by valves. In fact I would say your motor should be close enough cylinder vs cylinder to have vacuum or eyeball synch be the same ... and there fore eyeball synch is as good.
In reality ... maybe not. Then eyeball synch is better, Think about it, if you set the butterflies @ idle and 1 valve is looser than the other in 1 cyl, you'd set the butterflies off, and when you're 1/2 throttle the 2 butterflies are off enough that the air flow to the 2 cyl is different but the motor isn't affected any more ... if you get what I am saying. In other words, getting the motor involved in synch using its vacuum is a bit irrelevant, @ idle vacuum is high, as you rev vacuum drops and sorta loses significance.
Cool.
buddha.
Buddha, what is an 'eyeball sync' and how can you perform it?
All the instructions I've seen on doing a carb sync seem to involve using a set of hoses containing a liquid (1.55 carb sync tool, etc.) - is that a vacuum sync or an eyeball sync?
"Eyeball" means just looking down the carbs, from the air inlet side, and ensuring that they have the same gap from throttle plate to body.

Synchronizing or carb balance makes your carbs work as a
TEAM, most noticeably when twisting the grip right off an idle. The farther you get away from an idle, the less carb syncing/balance comes into play.
If your bike is warm and it wants to stumble/hesitate or not run smoothly when transitioning to just above an idle while in gear, you probably need to have it done.

Can you give a bit more info on this please? I am used to flat slide carbs and get all confused when speaking "CV carb" lingo :dunno_black:
Thanks in advance
