Well I tried posting this in the mechanical portion of the site but apears no one knows shit, so thought I might chance my luck here; below is what I posted last night.
Ok I have taken a VM29ss with an accelerator pump and intend on using it on my FXR150. It is the first time I have really started from scratch with a carb on a buke so just looking for a bit of advice.
Put it on the bike and put in a 130 jet based on not really to much.
The bike started fine and idled not to bad, when I jumped on the throttle the engine would bog heavely and basicaly die. If I slowly creapt past that point and then rolled on it would rev strong through the remainder of the rev range.
Now what would be causing this bogging? I suspect either the piolet jet or the neddle position but I am only really guessing.
I did play a bit with the fuel mixture screw, but it didnt seem to make any difference to the problem.
Another observation I made was when I pulled the carb off there seemed to be very wet in the inlet manifold with fuel. To bigger main jet maybe?
Advice welcolmed.
Further to this I have had a bit more of a play tonight and have come to the conclusion that I am getting a heap of spit back through the carb so really need to have a look at my float levels, also went down to a 120 main jet and it seemed to make bugger all difference (actually the smallest I tried was a 90 main jet and it was well lean but but still spitting fuel)
Anyone got anything to comment on?
