Exhaust port vein
nice collection of parts there......i have a question in that picture if you look closely at the roof of the exhaust port i couldnt help notice that vein and how it extends out to the opening,has that been the result of port work or is that stock, i want to put my finger in my hole and find out but dont wanna take pipe off,,the reason i ask is i had veins to help with turbulence ground into my ford iron heads and im wondering if its the same principle,it aids in directing the flow where it suppose to go.....

A smaller carb like the 41 would be easier to suck 2 1/2 times the fuel needed for the methanol because of the signal strength but its hard for me to believe that a 41mm would make the same HP as a 44 or even 50 like I run.
But I am sure the throttle response is excellent on that carb.
Not trying to spar with anyone just stating my opinion
And if you want to a big carb look at a pro-stock snowmobile
I know a guy running 57mm carbs on a 3 cylinder 1000 thats only 333cc for each 57mm carb!
I can't remember the name of these carbs but I swear my 50mm lectron would pass thru that carb!
They are made from billet aluminum and use all mikuni tuning stuff and no they are not the cutler carbs

whether its 2x or 2.5x or 3x, the point is you need to get alot more fuel in the engine somehow. (and as a general rule you can plan on 2x more). so with the extra fuel wouldnt you need more air ? 41 seems a bit small for a 500cc single cylinder. do you drill out the dump tube and main jet ?... cuz i aint seeing how your putting 2.5x more fuel through. 23% more power seems a bit optimistic, around 10% would probly be more realistic

air flow doesn't increase, the amount of fuel does. The fuel ratio for methanol is in the area of 5.0-6.0 to 1 where gas is 14.7-12.5 to 1
Now a 41mm on 500 especially a modded one will have higher a velocitiy and cfm of air threw it compared to a 250 but that is because of the signal strength a larger bore creates.
41 are very common on 250-330 cc drag/dune motors but they will have larger jets because of the weaker signal strength. But they do make more hp on a 41 than a 38.
But in the case of glens application torque and throttle responce is very important so 41's have ther place on 500+ motors.
I drag in the sand so I have allot of tire spin and hp wins in flat racing so thats what I am chaseing.

no problem chopping an alky motor 4 or 2 stroke if tuned, ask any dirt car racer

my "late-model"guys 'll drop a 355 chevy from 11000 to 6500 or close to while they pitch the car into the corner, usually they hook so hard they carry the front left tire the entire race, and if they arent careful the front right coming out of the corner, so ya kinda the same thing after the big cornering inertia and the acceleration they're getting its likely more forces than the bike
