E50 70cc dmp mods

Hi im currently running a e50 with 70cc dmp. Was gonna have a go at a slight port.nothing fancy.

Plans are..

Transfer match.

1 to 2 mm off piston skirt on intake.

Mat h manifolds to ports.

Possibly open ports by 2mm.

What are your thoughts?

What ignition?

What pipe?

What carb/intake?

What gearing?

What clutch?

Re: E50 70cc dmp mods

Just widen exhaust....

Re: E50 70cc dmp mods

And be sure ring clears ex. port at BDC and reaches deck at TDC first...

Re: E50 70cc dmp mods

Standard points ignition,External condenser.

17mm bing carb and manifold.

Standard gearing for now 16-45 . What would you recommend?

3 shoe clutch with blue spring.

Akrapovic exhaust.

Re: E50 70cc dmp mods

18 x 45 or 16 x 40 are identical but pretty good...

Really?

Re: E50 70cc dmp mods

Before you do anything get yourself an expansion chamber pipe.....not kidding...

Re: E50 70cc dmp mods

Iv tried to upload a photo but for some reason it wont?!

My exhaust has an expansion chamber but towards the rear before baffle.

That any good?

Or are chambers straight off cylinder best?

Re: E50 70cc dmp mods

I neef to see the Akrapovic exhaust.

Re: E50 70cc dmp mods

I can't upload a photos!?

it looks just like a biturbo.

I like the look of the circuit exhausts which style is best

Re: E50 70cc dmp mods

They don't even list one!

Either out if production or someone has just stickered it up.

Re: E50 70cc dmp mods

Right I've just port matched my kit. Trimmed about 5mm off base of cylinder hanging over transfer port.

Opened up the intake and exhaust without altering the ports.

Trimmed 1mm off piston skirt.

And opened up the inlet manifold as far as I could to reduce the 90deg angle

Been for a test run.

It pulled miles better! Booom

Re: E50 70cc dmp mods

Treatland has pipes...and every other part you could possibly need....
