Surfriding Options on a single carb for 62T

[Jet_jase]

I have a heavily ported 760 62T/61X motor with dual 38's at the moment but would like to swapo for a single as i ride surf and want it to be a more simple set up.
What are my option for best performance output as i don't want to lose power.
I have a friend lending me a ATP single mani with carb to try but some say try the Blowsion mani with a powerbomb carb?
My current set up is FR2 Evo with 760 ported with B pipe, stock ignition and mod waterbox...will be going for a MSD enhancer very soon to.

@Gliderskier loves his single carb on 62t setup.

I have a 62t case ported 701 61x with the adapter and a single carb mani. Runs great. Using a 44 since it's only 701. Maybe a 46 or novi 48 single would be an option for your setup

I've managed to get hold of a atp mani and a 48 novi. Will I need to upgrade my reeds?

You don't need to but why wouldn't ya? I run V force 2's

Before you make a change, check your high and low screw setting on your dual carbs. If they are not the same, which they probably wont be if tuned properly, you are going in the wrong tuning direction.

Just a thought as air flow may change due to there only being one carb now?

My old ported 760 loved the dual 44's but the mpg was Killin my ride time and distanc. Swapped to a older full spec 49. Seemed to run out of steam on the top end.
IIrc- black spring 2.3 or 2.0 ns 130 pilot, 180 main.

180 main nice! did you notice better throttle response with the single?

Really the dual 44's were the best that motor had. They were dialed in. But it was in an x2 so I had to run a smaller tank. I would be empty with the duals while my buddies would have 1/2 tank.

UPDATE - So i have now got a 48 Novi single on a ATP mani.......Powerwise i'd say i have gained a fair amount and my top end is not affected either. I was wondering what the fuel consumption would be like but that's unchanged also.
So i would say it's well worth doing as ive gained the simpleness of the single with a nice increase in power... i can also get my electric box out without taking my airbox off too

Now try it with dual 44's and let us know how that compares.

 

[Gliderskier]

Big single carbs for the win

Just for tuning!? Or did that include the carb and manifold?

Find a single 49 full spec. I had one on a bored/ported 701 with a pipe and it ran awesome.

What intake are you running? I have a 650sx intake bored out to 44mm with an adapter plate I have been thinking of trying.
