It sounds like the lectron carb makes a little more power than the tm45, but which one is more responsive when you gun it. also, has anyone tried the mr. hp 44mm powerjet carb, and how is it when you first get into the throttle.

 

i am also curious about this lectron 44mm...

 

I was noticing the dyno #'s Mr HP gives on his website for the Lectron 44 and 46HV. The 46HV only produced about 2 more HP and the same TQ as the 44. Not much of a difference for $200

Does the 44 also require the billet thumb throttle like the 46HV?

 

The only problem that I have niticed with the lectron carburator is that at an Idle , when you wack it, or lightly feather the throttle , it has a tendancy to stick due to the vaccum pressure.

 

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.

 

i'd like to find another 2 hp x 10[img]i/expressions/face-icon-small-happy.gif[/img]

 

I will try that setting to get rid of the "stuck" throttle at low idle.

Thanks
