Motion Pro
Hi, I also use the Motion Pro sync tool and I did put it on the bike before I touched anything else and guess what ? Much to my surprise (sic) not one of the carbs were in sync. You can read elsewhere on the forum a lot about how badly tuned and setup the bikes are when they leave the factory (One title said something to the effect "Isn't it sad that a company that uses a tuning-fork as a logo ....)
Although you're not splitting the carbs when you take them off, it is always a good idea to balance them when you put them back If you've taken the tops off or the float bowls. I would recommend that you do it in any case. Yes, the bike runs fine, but it can perhaps run even better.
But the reason for me sending this reply is a gentle word of advice: Be careful not to drop bolts, washers, Allen key or anything when you're doing this, especially on cylinders 3 & 4 ! Next thing you know, you're taking the starter motor out to retrieve the f..... washer or bolt once it has slipped inbetween the starter motor and the crank case.
Guess what happened the first time I tried to balance the carbs ?
