The difference in the hp on the domes is more than theory we proved it years ago when I was using rs125 engines in shifter karts, but I understand your points. the only reason I can see they use the top o-ring is to hold the dome in place as you slide it down the girdles. which is a valid reason...

A All really good points which I agree with. Im wanting to allow people to put a performance dome into their ada head as well. I can do it im just not wanting to lose the oring that keeps the dome in when you put the head down on the studs.

I can make some super high performance domes and then also make some stock style domes. It would be better not to have to do this however

Im with you on this one. I really want to use the same plug. the issue with the counter bore I have to do is it leaves it thin in the o-ring in the top. This o-ring can be left out out but then it can make it hard to put the head on as the domes now have nothing to hold them in place. i hope...

The ideal for a plug in a two stroke combustion chamber is about 6mm off the top of the piston. The squish band should be parallel with the top of the piston. The Yamaha is a dome piston so its actually supposed to be a curved squish band only slightly. if you have a squish band heading off a...

They are priced well I agree, do a good job sure I guess, its a very old style combustion chamber which leave a lot on the table, but i hear what you are saying i am trying hard to get both parts sorted, It just the issue of getting the spark plug close enough to the centre of the chamber is...

We have been making a new head for the 62t engine with a proper shaped combustion chamber. Its always nice to make things backwards combatable so we will make the heads use the same style of dome as the ada. This means you can buy our domes and use them in the ada head and you can use the ada...

Its not all there, some of the water jacket parts are but not all of them

They are not my molds. Making the molds is about 25 of the cost machining etc also adds up there. If you buy a manifold and header pipe as one. I will give you a 25 credit in the store on your next purchase

Thank you, we just restoked on those

yes it is

That blue pipe looks awesome

We are looking at different coatings to make them the best we can. Leaving them sand cast can make them look rough.

It will be powder coated Black

Thanks for your support

Thank you

Good things come to those who wait and we think you have waited long enough, So here it is guys. The mold is done and the sample made, We are tweaking the mold ever so slightly and then full production starts. Don't miss out on the pre-buy...

Isn’t a lot of Harley Davidson parts made there now as well

There is no point to make a flywheel. Simply take the magnets out of the steel one and machine it down

The issue of high static angle is a problem when you have one lump per flywheel. I have spoken to Borut a lot about this. It’s not an issue with a two lump. As it’s picking up a speed reference every 180 degrees not every 360:
