How is that Lectron 44 carb? I ordered one. I hear the push on it is lighter than the RWR45. Are you using thumb throttle or twist?

Thumb, feels close to stock with more travel but very nice perfromance when dialed in. You'll like it!

I have a stock valve head, with port work, and the port work made a BIG difference. DSmike has gotten all you can gett out of a stock valved head, and he does very well against the big bores, But I'm sure he would like to get his hands on a RWR stage3 head and give it a whirl[img]i/expressions/face-icon-small-wink.gif[/img]

But for the majority f the guys that runn normal high compression motors 11.5/12.5 I think thier is little gain in large valves, but a little gain,is STILL a gain, right?[img]i/expressions/face-icon-small-happy.gif[/img]

My engine builder advised me not to go with the oversize valves due to reliability issues. I can't remember exactly how he explained it but something around the valve area wears faster. Maybe valve seats or seals or guides, not quite sure....

My buddy just broke a vavle this past weekend. Said the valve guide had an egg shape to it. I want bigger vavles but not as big as what Ron Wood offers. Maybe 1-2mm more.


Anyone here using a lectron carb? DId ya use the stock thumb throttle cable to get it to run?
