Midrange is also boosted by longer pipework. Get a proper can on it too.

Re: new to rvf400's and wants more low end
Extra 0.5mm washers and HRC slide springs will sort the midrange flatspot out so in effect give you better midrange but the 2.5mm drill mod is just for NC30 carbs i belive. But to be honest sounds like somethings wrong if its that guttless low down, or does it just feel gutless because you've just stepped off an R1??dr_46 wrote:ok i will take ur advice on that sounds logical....what will extra washers and drilling out the sliders achieve

Err, where did you drill exactly? Pic please!
I can't remember what rvf slides look like, but I thought it only applied to vfr slides?

Ya that is normal on rvf's.
Remember to set your pilot screws while you have the carbs off - 1 & 5/8 turns out.

That's for vfr carbs mate, best to set them to 1 & 5/8 turns out for rvf carbs.
