Premix advice

So after killing one cylinder I rebuilt the whole engine from scratch. New bearings and seals, a malossi bbk and head. Its got the multivar variator and and LV3 pipe. I have changed the belt to malossi and the centre spring and the clutch springs are also malossi. I left the carb and air box stock but I am finding it impossible to tune. So I have now ordered the malossi carb and filter (think its 19mm). I know I will have to premix. Will it be 32:1 or should I go to 25:1? I presume I can take off the oil pump and the tank once I start to premix?

Its a 1985 UK vision, well just about nowadays :lol:

Seems like 32:1 is the golden number around here.

get a pump plug for a af18 or af16 it will fit your af05e engine that way you can remove the oil pump all together and gain a little case pressure as well .Oh and id go with 32:1 with full synthetic 2 stroke oil

4000/128 = 31.25. Close enough.
Plugs can be ordered from vendors like DayWOT, VT Cycles, JiangWayne.com. They're 10-$15.

I'm going home to Hawaii in 2 weeks and I'm planning to stop by VT cycles to order some stuff for my upcoming build. I can send you one if you cant get one by then. Theres lots of them on ebay as wheelman has mentioned.

I just re-examined my post. I'd like to say that I invented a Secret Code for Joke posts where they start with "Greetongs" but I'll be honest and say it was a typo. If a suitcase full of Arrow, Scorpion, and Hurricane exhausts fit safely in the Overhead Bin, I'd say you could make a killing when you return. But if YOU say that they'll arrest you at the King Kamehamehameha Airport.

On my 90cc, I mix 200ml oil in every 10 liters of gas in a gas can, but I keep the oil pump since it keeps everything lubed during deceleration (downhill for example). The oil pump is there for a reason. The total oil ratio, (premix +oil pump) is about 30:1. Buy a cheap CHT gauge while you're doing final setup so you don't toast the thing:

You can remove the CHT when you're done tuning, and save it for your next build. It's cheap but won't last forever if you leave it installed with loose wires flapping in the breeze. It's also not waterproof.

With the CHT gauge installed, you'll see that your CHT rises rapidly when decelerating from WOT. That alone should be a clue that you should keep your oil pump.

Just off-load the stuff from your Cessna 150 at the Lanai Airport :naughty:
