38's on a 760 62t

[dirtyjrzy]

Will fuel 38's work on a 760 62t or am I gonna be shirt on fuel

Yes they will work. Will have to tune it as stock jetting most likely won't work. You'll pick up a little bottom end snap with the 38s over the 44s but lose a little midrange and top end.

They will work

What jets would I use

Why are you doing it ?? do you not have the original carbs. Its a loss every where on the 38s

I have a 62t 701 that is bored to 84mm (stock bore for a 64x 760), so very similar to a 760 but a little lower port timing on the exhaust. I ran it with stock 38mm carbs and the jetting came out very close to what factory pipe recommends for a 701 with a b pipe (it had a b pipe).

One of the strongest Freestyle ski's I ever rode when I was competing was a warmer built 760 with 38's. Hit like a freaking hammer!

I got the 44's I just hate rebuilding them I can get a set of 38's for $150 put them on and go

$150 would rebuild the 44's doing it yourself. Its super simple.
Go 38's for gas mileage and throttle response.
Go 44's for power.
Either will work.

Thanks

Why would you spend money on carbs that may need rebuilding when you have a set that you know needs rebuilding ?

There are two types of carbs, those that need rebuilding and those that will need rebuilding., it's just a matter of time and either way you don't know which you have unless you pull them apart and look inside.

I am going to lay some wisdom on you, feel free to take it or leave it.

I don't buy carb kits, they contain a lot of parts you either won't use or do not need to be replaced, they do not contain needle and seats , plus they are expensive.

Second thing I rarely replace needle and seats, I test them with a popoff tester either they hold pressure or they don't, I do replace the sealing o-rings around the needle and seats, if they don't hold pressure then I replace them.

I don't always replace the main diaphragms either, if they are nice and pliable and have no pinholes they don't need replacing, same with the plastic discs in the fuel pump. same with the fuel pump rubber diaphragms,

I will say on Yamahas usually the main diaphragms are usually crusty feel like cardboard and need replacing ,also usually the gaskets stick on the fuel pump so you end up replacing the gasket and rubber diaphragm on those. On Seadoos the main diaphragms are usually in great condition and the internal filters are always filthy, their fuel filters suck , they don't use the gasket that the Yamaha carbs use so most times the fuel pump rubber diaphragms are ok as well .

The inner fuel filters on Yamaha carbs are usually spotlessly clean as Yamahas have excellent fuel filters.

I specialize in getting older skis back up and running, I just delivered a set of 701 Waveraiders three weeks ago. , an XLT800 the week After that, an XLT 800 last week and an XLT 800 and GPR800 today, all had been sitting over a year, the two today had been sitting nine years, all needed carbs rebuilt , some needed new fuel lines and gas tanks cleaned and flushed. all were delivered running perfectly.

Next week I have two 701 Waveventures , week after that two Kawasaki 900 ZXI's , same deal on all of those, I know of which I speak.

Thank you for the heads up

44s setup correctly will have better power and throttle response than a set of 38s.
its the loose all around if you take them off

 

[dirtyjrzy]

44'sare going on

The only downside to dual 44's compared to dual 38's is gas consumption, in ever other area they are superior.
