mmmm, turbo... for four strokes
or diesel twostrokes, i guess... someone always has to bring that argument up
the electric plastic ebay POS dont work. and definitely wont work on (conventional) two smokes.
these might...but not on a twostroke... or anything smaller than 125cc, at least...
i just bought one for my honda C50. with a lifan 140, of course
an AU$300 gamble...
i wonder why noone has ever tried to combine sleeve valves with a standard two stroke ? it only adds one (or maybe two) extra moving parts...
actually, i better google that because i am sure, over the last hundred years...someone HAS!
yep. rolls royce, who else?
interesting...here we have a way to close the intake/transfers AFTER the exhaust ports...allowing BOOOOOOOST!
back on the NOS side of things, easiest way is to use a mikuni with the "plunger" type chokes. they automatically add more fuel (and air which is why any engine with a mikuni plunger choke revs its head off when warming up on the choke...) just feed the NOS into the chokes air bypass inlet hole thingy... and either start drilling out the choke jet(? its not really a jet) for more fuel or adjust nos to air ratio...
i think its the top hole...
varies between models.
side note, i found out about these recently...
a mikuni DOWNDRAFT carb
be just about the right size for these lil twosmokers... and allows for a far more direct route into the intake port than the standard NT carbs. with the right manifold of course
