The importance of synchronizing carbs
I did this writeup on another forum and thought some people here might benefit from it as I explain what synchronizing(synching) is, and why it's important to synch your carburetors/throttle bodys, and most importantly the benefits like better gas mileage. Feel free to post any questions.
Here's the link: http://www.twtex.com/forums/showthre...+synchronizing

Thanks. I'm at home on the iPad and can't copy/paste paragraphs.

How often/miles you recommend to sync the carbs?
Non synch carbs possibly cause the engine to slightly rev at times? Barely noticeable on the rpm gauge but audibly noticeable. |

It definitely needs set after any carb work or when the valve adjustment is done as either will change the synchronization. If they are out it can cause erratic idle as you are essentially opening one carb more than the other and thus putting more fuel in one cylinder.

If this has motivated anyone to synch their carbs, the DIY can be found here.

I'm new at this. When synchronizing the carbs, do I need to remove / release the throttle cables? or just leave it as it is and balance the carbs directly using the screw in the middle?

Make sure the bike is warmed up and idle is adjusted properly before you start. Leave the throttle cables attached. They play no part in it as there shouldn't be any tension on them at idle.

I always start with the basics. First i replace spark plugs, then check valve adjustment, then synch carbs. That way your covering all the major bases and your not doing double the work. There are many good writeups on doing valve adjustments and carb synchs.

it's an 06 with 25,000, but this was taken after a ride where I lost an exhaust gasket--you'd never have this kind of discrepancy in normal conditions.
