Moderator Posts: 9480 1700 float level... 9 Years, 4 Months ago   Anybody know the measurments of the float from the mating surface of the carb for the 1700? At one time there was a pic of how the float should look resting fully on the needle. For a rough start, you could see where the ridge of the float should be, compared to a cast tower on the carb. Am I clear??? I went thru the carb tech stuff and cant find that pic, or Doc...do you have a measurment? I have the carb off now, outside, and it's gonna get dark soon. Any help would be appriciated.   Logged       The administrator has disabled public write access. #128837 Musky (User) Platinum Boarder Posts: 15137 Re:1700 float level... 9 Years, 4 Months ago   Did a search and found this. - Float level   Logged       The administrator has disabled public write access. #128839 Cougar (User) Platinum Boarder Posts: 3216 Re:1700 float level... 9 Years, 4 Months ago   4-5 mm above the mating surface is the spec for the 2004 and up Mikuni BSR 40....Coug   Logged       The administrator has disabled public write access. #128841 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 19602 Re:1700 float level... 9 Years, 4 Months ago   You can't measure it that way. There is some slack in the float mechanism .... in other words, after the valve makes contact with the seat the float will compress even more. Measuring the distance when the carb is upside down and the float full 'seated' is not the same as when the valve is seated. When the valve is seated the distance is 14.5 mm When the float is fully depressed it's 7 mm ... from the face of the carb to the bottom of the float. I think I've explained is better in another post ??? Doc .... wrong ...   Logged     My Bike Website   The administrator has disabled public write access. #128842 Blackroadie (Moderator) Sometimes I wish you were a pinata !

Moderator Posts: 9480 Re:1700 float level... 9 Years, 4 Months ago   Thanks doc...I thought that was for the 1600 "good" motor.   Logged       The administrator has disabled public write access. #128846 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 19602 Re:1700 float level... 9 Years, 4 Months ago   Oh yes .... these values are equivalent to the 1600 value of -3.5 mm measured according to the OEM tube method. You may be able to use ratios to determine what it would be for the 1700.

Works fine   Logged       The administrator has disabled public write access.
