If you don't have a carb synch here's how i usually do it. First you need to remove your airbox to see what ur doing then drop every throttle valve till they touch the bottom of the carburetor. To do so, turn the adjusting knobs clockwise.

Then, put one finger under one throttle valve, turn the adjusting knob counterclockwise till you can feel it raising just a little. Repeat this step to all other carburetors. Then, press on the throttle to see if they raise at the same time, to really make sure, use one hand and two fingers, put your fingers in two of the carburetors then press on the throttle and you will sense if they need readjustments.

Now place one finger in one carburetor and turn the idle screw in till the throttle valve raises a little again. Repeat this step to the other carburetors. Thereafter turn each idle screws in 1.5 turns and you can start your machine to fine tune the idle, to fine tune it turn each screws equally to obtain desired rpm's.

 

I have another ques on this?????? Can you use merc sticks to synch a zrt 800?

I have heard yes and no about using them on a 2 stroke, has anyone done it safely?

 

I have been able to use mine without any problems. I have bought the econo carb tuner from motion pro; since my carburetors were not equipted with adapters i had to buy some permanent ones that some bombardier snowmobiles have(F3's for exemple). What i like about these ones are the restriction of the holes which allow minimal vacuum and pressure to be created. The current setup i use is one restrictor in the hose, that is included with the tuner, and this adapter, which restricts even more the mercury to be sucked in by the engine. I am not really sure why they are not recommended for two strokes but, it probably has something to do with two stroke engine having more responce and that it could easily suck the mercury in without the proper restrictions. If your hoses are restricted enough you should not have any problems, just don't rev the engine too much; i have been capable of reaching 5000 rpm without any problems.

 

Thanks for the info, I also have the motion pro econo (it has worked great).
