Hi guys, I'm slowly getting my rd250b 75' (euro model ) on road back again and have question about new VM28 carbs.
My original hi top carbs are in very bad condition (previous owners hack jobs....), bike was running poorly and couldn't get it to work right (one carb body does have damaged air screw seat by using hand made jet?? , carb body where needle jet sits is cracked...) . So I bought new set of Vm28-57 to use it instead of original ones.
They came with 5DP39 needle and 169-n8 needle jet.
Engine is (will be ) stock, except one piece YZ reed petals , reed spacers and K&N YA0700 (couldn't find the original paper one here) .
I know I have to modify them for oil injection that is no problem, and change pilot and main jets ( start with 30 and 150 should be safe) but will that combo (5DP39 needle and 169-n8 needle jet.) work ?? Or I have to look for some other ones? I have found that some guys here are running those new carbs in their bikes, so maybe someone could shed some light on that matter?
Cheers guys.
