TPE MOTOR SETUP's - list your package

[Brian_216]

ok, so i've now ran and tuned 2 sets of carbs onto my 1105. so here's how they have ended up for me at near sea level riding.
the 1st set i dialled in where ATP 48's
2mm n+s 21 psi pops
125 pilots
135 mains
low screws 1+1/2 turns out
high screws 1/2 turn out. these carbs worked well but seem quite sensitive to changes in temp and weather as it has started to warm up in the uk.

2nd set that i have now dialled in are the full spec 49's
2mm n+s 21 psi pops
122.5 pilots
135 mains
low screws 1+3/4 turns out
high screws 3/4 turn out
these carbs, while not giving any more noticable overall power do meter more smoothly at partial throttle openings and hit very well

i have been playing with ignition curves for the TS and will post up a pic when i've ran it a while without destroying my motor

i have just hit the magic 10hr mark (new hour meter fitted on install of motor) so whipped the head again for a cautionary glance, all is lovely in there.
no visible migration or immigration problems from that pesky water ;-)

I think it would be helpful if you could also list your prop and pump size / pitch that's working with this setup. I also am interested in the curve you are using

Hey Lads,

I am in the process of building up a 964 with the below setup and looking for some advice on carb jetting, needle and seat sizing and timing to get me started, any suggestions most appreciated.

46 mikuni's (Currently 2.5 N/S 120 low 150 high, unsure of popoff have not tested yet)
Dasa manifold
V force 2 reeds
b pipe (machined out 50mm)
62t stator
Lightened flywheel
MSD enhancer
OEM coil
144mm 12 vein pump
14/19 large hub

This is going into my JB1 krash hull primarily for surf riding. Would love to be able to flat water flip it as well.

Thanks for your input guys.

We are running the same jetting in the 1105 and 964 on full spec 49s
125 pilot
136 main
1.8 n/s
23 psi pop off.

Is that a typo and you mean 135 main?

Sorry that would help. Lol.
Obsession fibre glass hull 45kg bare weight.
148mm maxx pump with 15/22 skat.
Bored exit nozzle to 85mm
And here's the curve but you use it at your own risk as I've not run it for long. 99 octane pump gas.

Tubes from inside the hood. These are threaded fittings so a nut is silicone sealed on and the flexi tube just screws onto them.

[skinnyman]

Can you post pic of the top of the hood

 

[kev.t]

Some extra breathing in there now too, pipes run on inside of hood down between fuel tank and pfp chamber so hopefully any water that makes it through gets dumped straight into bottom of hull with no clear path to carb throats.

Nice, thanks for the pics. Are those some kind of boat vent?

 

[kev.t]

They are yes. Keith found and bought them so would be able to steer you in the right direction.

Wow that is some nice looking hardware! (vents)

Can anyone recommend a consertive / safe jetting starting point for breakin for the 964SS w/ PFP on duel 48 novies. Thanks

Call Novi and ask for 1100 dasa jetting specs. For my Dasa 48 carbs, it was sent to me jetted for their 1100, and it was very close jetting wise on my 964 with powerfactor and MSD total loss.

 

[ChadGnarly]

We will post up the jetting specs for u shortly.

 

[xXx Octane xXx]

This should get you in the ballpark.

140 - 142.5 Pilot
120 - 122.5 Main
2.3 N&S
115g spring (22.5psig)

(Start with the larger jets)

I am starting with 145 Pilots and 122.5 Mains in the 48mm Novi-tecs I have on my +4mm 1021cc.

 

[truerider411]

TPE 1021 (PHP +4mm crank)
dasa 48's (140 low 1turn) (125 high 1/2 turn out) pop off at 20psi
Elevation 2200ft
PHP intake
51mm bored B-Pipe MOD
148mag pump 12/17 prop
67 jet fuel line restrictor
ATP HX3 ignition
Lightweight stock Flywheel
85mm bored reduction nozzle
ATP Water box

Our water is just warming up so optimal results will be in the next few weeks. But power seems very strong. We are running a little rich at the moment to break it in.

 

[zimmy]

Owed this to DAG for a while now! My setup (subject to change with the new VIPER)

TPE 964
Stock Stroke
160 psi compression (gauged)
Dual NoviTech 48's (140 low, 122.5 high)
B-pipe with true TNT Chamber
MSD Enhancer
Stock lightened 61x flywheel
Stock pump with Skat Mag stator
15/19 Solas
RIVA Intake with spacer
V-Force 2 Reeds
GP 760 rear waterbox

The motor rips, everyone who has tested it came back with a smile. In my stock hull I had comments that it felt extremely agile with the amount of power it was running (felt like a shortened ski). Other just asked where they could buy one.

 

[Brian_216]

I learned that the 1105 with the light weight PHP crank needs a slightly bigger pilot. I'm at a 130 now and have the low speed screw past 1 1\2. I'm going to try a 132.5 and see if I can't get it closer. I do not like having screws on a full spectrum any more than 1 full turn. A conversation with Ed and he will explain why.

Is this still the latest and greatest flame curve? Getting mine this week or next.
