Hi
I recently had the above kit fitted but I'm not to clued up on setting the carb.
I have trawled the web to find someone who has the RT 190 set up and running how it should. but with no success.
I have a 28mm phbh nk rally and mb remote filter.
Idle 58
Main 125
X7 needle second notch down
40 slide
Mix screw 1 1/2 turns out roughly.
It starts to splutter just as the power starts to come in
And on Sunday at the Humber bridge YSA event as I was going up the the steep slip roads I had to feather the clutch and give extra revs to stop it spluttering on the steep slip roads.

As said earlier I have trawled the web but only found threads on people with roughly the same problem as me.
So if any one has a similar set up. Id love to hear from you.

Thanks from a very frustrated Boris.

Main is too big, come down a size at a time until it runs clean, then check plug colour.

I'm still running in how far would you come down.
To keep it safe.

Just go down a size on the main, try it, if its still not running clean then down a size, keep going until it runs clean, do some miles on it and keep an eye on the plug colour.
