Help with predator 224

[aust9002]

Yeah that was an old pic i need to get a new one with the new tires

Dang but then i still have a stock piston, would my flywheel swap over?

It's a clone taper crank/flywheel, it'll bolt right on.

Your rod will too.

What's the number on the flywheel???

With a new engine, you get a new cylinder, piston, and head.

A stock dished piston is better then 1 with dipples in it.

You will need that DUCAR-TK throttle kit, unless you wanna run that slide carb,..... I wouldnt, but that's me.

Don't be surprised when that stock ducar 224 out pulls that pred 224 with the slide carb, fancy air filter, and you don't even wanna get me talking about that lazy slow ramped cam you have, .

I'm gonna order 1 just to check the clearances on it. Waiting on a return message about what cam they are using in it, and what the CR is.

I sent the message about 10 mins after they closed for the weekend.

No hurries, I got plenty of stuff to tinker with.

Not hating, to each his own.

We've tested over 20 cams with the same test engine, gearing, stall, tach, speedo, and stop watches.

I won't be recommending it, sorry.

I probably won't be hearing from Dyno Cams til monday.

I let you know what they say about the 224.

It dont really matter what they say, I'm sure I'll be changing things anyway.

Yea, those dimples will lower lower the compression ratio by about .0000001%.

better than the lawnmower tires lol

I need some lawn mower tires. Wanna sell?

I think im more worried about structural integrity and all those other things like hotspots, destroying my cylinder wall etc...

Theyre used lol but sure $10 each with whatever shipping comes out to

 

[Master Hack]

What sizes are they? Tires only or are they on wheels?

@aust9002
Sorry bud, I can't help you.

Just do the best you can with what you got.

Don't forget to buy extra oil and hotter sparkplugs.

And what spark plug? I also always run 93 octane if that makes a difference at all

My point is those dimples won’t hurt a thing. Just make sure the rings move freely in the lands of the piston. Why spend money you don’t have to? The dimples will fill with carbon quickly and all will be right with the world again.

Here's some important info about the 224 crank and aftermarket cam clearances.

Dyno Cams has cams that are ground for the 224.

I perfer Isky Racing Cams. They hit so much harder down low.

The Black Mamba Jr cam is whats in my 224, but i had in out at least a dozen times jus to get .030"-.040" clearance.

But always check the clearances when swapping ANY cam in the 224.

I recommend running the Ducar 224 stock outta the box for at least 10 hrs, before swapping carb and rod. Getting every thing broke in good, a few oil changes and see how you like it 1st.

Also do I need one of those pulse fuel pumps? I tried using one before but it would flood my carb
