I give between $1.25 and $1.75 a gallon. You burn twice as much as you would gas.

Ward, on a four stroke, the main jet alone can supply all the fuel needed for an alky motor. A 2-stroke requires so much more fuel at WOT than the main jet alone can offer. That is why most 2-stroke alky carbs have a booster jet. If you went with a HUGE main jet in the 2-stroke, the fuel wouldn't atomize correctly.

 

Thanks for clearing that up for me AlkyX.

 

i guess this thread is probably old..but i want to run alky though my raptor when i go to the dunes this summer... ill have a banshee to hit the dunes on and want to drag onmy raptor... so what needs to be done to the stock carbs? would i need a bigger pitcock on my tank? any help appreciated

 

remember to drain the stock carbs after runnin alky in 'em or it'll dry up the rubber.

 

bump.......... any info on how big to bore mains..do i mess w/ any other jets? and what about the needle..if the main is bored way out then how does the needle work?

 

Risener151, most stock petcocks are large enough to supply an alky engine. Some large (500cc+) banshees, quadzillas, etc, need a pulse fuel pump. Four strokes like yours should be fine. Do a little more searching on here. There were a couple of stock raptor carb conversions recently.

Justdragit, you run gas through the engine to flush out all of the alky so it doesn't draw moisture that causes corrosion. Not because of the seals or gaskets.
