when i talked to eric he said the stock throttle would not open the 44 all the way either. that the 44 does need the moose throttle also. i think its definatly worth asking if the 44 has the same throttle suck at closed throttle as the 46hv. now in all fairness i havent been out trail riding with the bike yet so maybe ill get used to it or maybe it get better the more you ride. but just in the riding i did around here the tight technicle stuff was a little hairy with the throttle sticking shut like that.

I have a 44mm that I just got back from being setup by mrhp and 222. Infact my 44 was one of the carbs that produced those numbers on the net. It does seem to stick a little at idle but not that bad and I think that a little stiffer spring would fix it. The 44 will work with the stock throttle but you have to modify it to pull the slide all the way up. I have a HPD billit throttle and cable with the 90deg bend at he carb end and that seems to work really well. I will post some seat of the pants improvements when I get the bike out in the dirt this weekend.

The stiff off idle charicteristic can be easily cured by richening the needle about 1/2 turn and screwing the air bleed in. This will cause the engine to idle too low. Turn the idle screw in until it idles at about 1500-1800rpm. Idle will be a little too rich with this setting but it allows the slide to be set at a higher position which lets air pass through easier and helps the vacuum stiffness. I have been hearing alot about this and finally felt it on the dyno with some lean low end settings.
44mm vs. 46HV: 2hp on a bone stock engine is extremely hard to find. It took two years of R&D on the 46HV to find 53hp. This made it alot easier to get reasonable power out of the 44mm because we had a good starting place.
If you are making as much power as can possibly be made with a bone stock engine and then find two more horsepower for only $200 wouldn't that be considered a good deal??
Throttle responce on the 44 and 46 is instant right off idle.
