Suzuki 2 Strokes

New to 2 storks this so might be dumb to sum.
On my GT380 the piston crowns and ports are rough, now on my 4stroks I would at lest smooth or polish them.
So is this not dun on 2stroks, I would have thought it would at least slowed down the carbon build up on the pistons and in exhaust pots?
Any enlightenment would be appreciated.
Regards Bill Dag.

I polished my GT750's head and exhaust ports to keep carbon buildup down, it helps.

Absolutely, Bill, polish the pistons and exhaust ports. For sure you'll have less carbon buildup in those areas.
If you've got lots of time (and the desire), have a go at the transfers and intakes as well. Just don't be too "enthusiastic" with the Dremel.

Polishing the intake ports is a great example of a bad idea. The fuel atomizes much better if those ports are left rough. Many a hot rodder spent mega hours polishing intake ports only to find out that it ran worse than it did before.

FYI, we never bother to polish anything on a race bike - apart from the paint and then only reluctantly. There is a tehoretical advantage to polishing piston crowns and ports to prevent carbon build up. But other tuners claim that a layer of carbon acts as an insulating layer to prevent heat transfer.

Polishing intakes and transfers is a bad idea under any and all scenarios though.

On race bikes we, seriously don't polish ports or pistons. Any theoretical advantage is not measurable in the real world, so I wouldn't bother.

This what I have read also, otherwise your fuel lays like a sheet over the polished ports and may come off as such.

Well, you gents have a point with the better atomization thing. With the crap fuel we get these days, any improvement in atomization is bound to help combustion.

MMMM
Looks like we full on the side of leave it as it is.
I guess by the time the charge has found its way up and down ports and flung round crankcases southing and blending is not going to do much.
I always smooth (Not polish) and blend the inlets on my 4stroks.
Doesn’t make a noticeable difference in power, but the engines do run smoother.
My thanks to you all
Bill Dag.
