This is the KT head I last shared that we were reworking. It's now 1cc less in volume which puts it right in the sweet spot!
Mint job Greenslade Engineering 👌🤙

While I was at my day job today Greenslade Engineering we're slugging away at welding up this KT100S head for me.

Yes it looks half OK as it is but there's always room for improvement. For this particular build we aren't compromising anything! This one is part of a gun KT Twin package we're working on for the Aussie Title's next month.

Very keen to share some pics of this as I make progress on it so stay tuned!

We're pumped to say our very own Nate Greenslade will be taking on Australia's best Dirt Karters at Loxton in October!

This year we will be competing in the 100 Open and 200 Open classes!

Time to get stuck into some proper preparation ahead of schedule 👌

Thank you once again to Greenslade Engineering for reworking this 100J head back to where we like to see them!

Stock vs Modified exhaust and intake ports on a 100j cylinder for a no rules speedway racing class. Exhaust port is now 96 degrees opening from a factory 102 degrees. I also cut back the cylinder liner base.

I think this will also benefit from a cut piston skirt on the intake side to increase intake duration further. But nonetheless this will make a big difference!

Next job skim the head to drop the cc's.
