Carb Question building race blaster

Like i said before, we ran 210psi on little 54mm bore taiwanese scooter motors in our mini quads and they were very reliable and fasssttt! I would have to believe a jap blaster motor could handle the compression if a taiwanese scooter motor could.....
I can tell you we will be at least 200psi on my motor, maybe I am off but it worked for smaller less reliable air cooled motors.....
 
yes, the lower the first number, the leaner the mix actually is


the jets will allow an amount of fuel/oil mix in. it doesn't know how much of each is there, the same total volume goes in, so if you add more oil, you effectively reduce the amount of fuel that can go in

100gallons of fuel to 1gal of oil is 100:1
50gals fuel to 1 gal of fuel is 50:1
lower number ="s richer mix
higher number ='s leaner mix
 
i was talkin 100:1 versus 40:1 for the leaning the fuel/air mixture

and that 100:1 is funny, cause here it is again..........50:1
last paragragh!!!!!!!!!!!!!!
on amsoils site it lists "saber" as the only 100:1 ratio oil

and another amsoil.com link stating 50:1..............
AMSOIL - DOMINATOR Synthetic 2-Cycle Racing Oil


DOMINATOR® Synthetic 2-Cycle Racing Oil (TDR)
DOMINATOR®, an AMSOIL exclusive formulation, lubricates and protects high-performance two-cycle motors, both on and off the track. High-performance motors, particularly those that are modified, operate hotter and at higher RPM than recreational motors, and they need good oil for peak performance. DOMINATOR is engineered for racing. It has the right film strength and clean-burning properties for “on the edge” operation.
* Not suitable for long-term use in outboard motors as a TC-W3 type oil, although excellent as a race oil for short-term use where motors are periodically inspected.

  • Provides excellent film strength for high heat, high RPM motors
  • Reduces friction for maximum power
  • Recommended for use with coated or non-coated racing pistons
  • Suitable for use with exhaust power valves
  • Recommended for use with high octane racing gas
  • Burns clean; helps prevent ring sticking and plug fouling
  • Provides excellent protection at 50:1 pre-mix or in injection system
See Article: Two-Cycle Engine Applications and Lubrication Needs
Super Film Strength
High-performance two-cycle motors have high compression ratios, which significantly increase combustion chamber heat and crankshaft bearing pressures. Hot combustion processes quickly burn off and evaporate light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances. This promotes piston scuffing and possible seizure, and increased pressure on crankshaft bearings promotes metal-to-metal contact, wear and pitting.
High heat and pressures require tough oil with better film strength and more lubricity. DOMINATOR, constructed with AMSOIL heavy synthetic oil, handles high heat better than mineral oils and provides improved film strength and lubricity. DOMINATOR reduces friction and provides an extra measure of protection against piston scuffing and crankshaft bearing wear.
Clean Burning
High combustion processes require the proper additives and oils to control deposits. DOMINATOR contains strong, high-temperature detergent additives and highly pure AMSOIL synthetic oil. It helps prevent deposits that cause ring sticking, plug fouling and exhaust port blocking. DOMINATOR is an optimized product for severe service.
Applications (2-Cycle Recommendations Chart)
DOMINATOR is recommended for use in high performance stock or modified two-cycle motors, including air or liquid cooled snowmobiles, personal watercraft, motorcycles (Moto X), ATVs, go-carts and outboard motors*. Good for use with coated or non-coated pistons, high-octane racing fuels and exhaust power valves. Compatible with most other two-cycle oils, however, mixing oils should be minimized.
Use at 50:1 pre-mix ratios (2.6 oz. oil per U.S. gallon of gas) or as injection oil where JASO FC or API TC oils are specified. Not suitable for use with alcohol or nitro-methane fuels
and i have ran dominator for hard recreational riding, and thought it sucked, my motor did too, then switched to klots suoer techniplate, and it carboned up my motor so bad, pushing out the rings and wore them out

it's "maxima suoer m" for me or nuthin at all !!!!!!!!!!!!!!!!!

I stand corrected. I have ran it 40:1 for a year now with great results. I used to run castor 927 and after 3 races had massive carbon buildup. I took a piston out of our motor after 8 races using dominator and almost put it back in, it was in like new condition. I am a believer in amsoil dominator and will continue to use it.
 
any guess on jetting where to start. Has an FMF fatty & power core2. Will be running open filter for now. Reason I ask is they will send jets with carb to get me close.

depends which carb your gettin
i would think the 33pwk will be very close to my 34pj ????
which has...........
155 main - 162 for the cooler temps in sept - nov. but done till spring
45 pilot - airscrew somewhere under 2 turns out
"dgh" needle

absoluetley rips from bottom to top with the mods in my sig

Well seeing is believing. You get it built up , let us know. Even on BHQ I haven't seen over 190 psi even on alky.
