My chop chop

Hi im from Oz and this is my 2 stroke Schwinn in progress... I've done the usual mods including a severe dose of heavy porting.

I got bored so I polished the engine covers to a mirror finish - I reckon this looks much better than the same crappy slotted cnc covers that everybody has.... I also did a little porting and port-matching with the inlet manifold...

I've ordered a aftermarket cnc head as well as a 4 litre fuel tank that should arrive very soon... I'm gonna give the head a skim to raise the compression slightly just to give it shooting match a little more oomph... let's see what happens aye... lol

Check it out

I've gone back to the ape hanger-styled handle bars, I reckon it's way more suited to the styling of the rest of the bike...

Very sexy!!!

Aye !?....... I've had these exact handle bars on this exact bike in the past but it never felt like this before ! I wonder what it could be.... the exhaust perhaps ?

They go hand in hand. A good looking, good sounding exhaust has to have a matching set of handle bars. I love the look. It really makes me want to build a chopper. If I didn't have all these other projects going on right now, I would probably start buying chopper stuff. My next door neighbor would flip s**t!! He wants a chopper MB, and wants me to build it, he just don't want to pay the cost. lol

Porting done right - a timing wheel must be used to achieve correct port timing all around.

You had me at timing wheel.

This is from years of practice from porting car cylinder heads....and I'll let u in on a trade secret - when porting, don't use grinding stones in a power drill like everybody else - that's the easy way to destroy a cylinder from taking chunks out of it...
Dremel has some tungsten tips that are great for fine detail work.
I start off with a larger cylinder-shaped tungsten tip on a air-powered die-grinder to achieve the general shape I'm after, then I'll tidy it up with the smaller Dremel tungsten tips (see photo) to achieve the consistency you see here. They're not cheap as that's about $100 worth you see in the photo, but they're worth every single cent.

The only port I'll be polishing to a mirror finish is the exhaust port. The rest will be left in this semi-rough texture to aid in atomisation of the fuel..

I'll have to pick some of those up. I been using stone for the fine work.

Just google them.
