I wanted to learn where in the rev range the slides controlled the mixture & to what extent the modifications had to the running
Some might of read about the 3000rpm fuelling issue I have
, so whilst stripping the carbs down for the eleventy first time, I decided to modify the slides for the hell of it.Here are the pictures
This picture below, highlights the angle I used. It increased the leanness from 3500rpm, & cleared its self at 5200rpm.
This is of one fitted.
This is the pair lightly sanded.
After learning what the above modification did, I decided to flat the slides down so there was no radius left & see what happened then.
The bike ran horrifically lean now, not even choke would help the issue at 4000rpm.
Here are the pictures.
Please remember, I knew the slides were on a one way journey to the bin as soon as I touched them with a file.
The lesson to be learnt is if you have a rich issue at 3200rpm to 5200rpm, cutting the slides might help you lean the issue.
But if you already have a lean issue, you'll turn your bike in to one of those mechanical bull fair ground rides
