Im not talking about you i am talking about the people that are telling you about the single carb cant flow enough fuel thing

Seriously do people understand how carbs work If you have more airflowing through a carb then you get a larger pressure drop across a jet this makes more fuel flow through a jet There is no way any carb company would make a carb that can not flow enough fuel to cover the amount of air it can...

Thats would be awesome if the carbs were only flowing for 180 degrees of the intake cycle per cylinder but with the ram effect due to the weight of the air then you will find that the intake cycle is longer in duration You also have to remember that when the reeds shut they send a pressure...

yes they run a 1.5 mm n/s

yes it will fit

Its a good pipe some people struggle to set it up correctly the b-pipe is alot easier to get running right the b-pipe will give you better throttle response if you dont have a decent amount of timing in your ski

i hope they dont change it every one is alwasy wanthing to change it one day they will get there wish and it will go four stroke then every one will be complaining

Wattage is right you need racks of timing and it comes alive its a great pipe and makes heaps of power i pulled my one back to about 15 at 7100 to help it rev on up top then started racking timing back in at 7300 taking it to about 18 at 7500

I use studs in my race engines as well it spreads the load on the threads

i have a stroker crank all drawn up as an iges file if thats better than a junk crank

do you have a girdled head on it

Reverse jetting works because there is a lag in fuel flow over air flow in a carburator this is because fuel flow is goverend by air fuel and so it comes after the extra fuel down low responds quicker and gives you more punch down low It also helps keep the cases cool and gives you a larger...

So a genric sort of yamaha build or close to it put in a larger low and a smaller high say a 130 low and a 115 high it will hit harder down low and rev nicer up top thats a massive high jet you have in there

whats the setup on the sj you may find its your carbs that are out slightly and you could go quite hard with what you have

300 440 550 650 750 sxr superjet square superjet round 2008 superjet xft octane and a 3d

Yeah i rung him as well It didnt help me in the least some one suggested that its because i had a dry pipe versus a wet pipe and that the carbs were different thats just meant an excuse for a bad signal in a carb to me

are these on a sj

What carbs are you pulling off

Thats fine each to there own I had f boosters on there and went to a set of full rectums i brought of joe kenny when he was over here This was on advice from some on who posts on here told me they got much better power on there dyno with them I was setting them up on my type 9 race superjet...

Dont waste your time I have found novis to be way better than full specs yes i have done the conversion i had 48 novis then put on full rectums Im now back on novis and i will not be changing back ever
