The Leviathan Project

@gareth_iowc Yeah I did write a reply. Must have forgot to send it.

Basically it's not as simple as: grab a YZ that'll do

There is a bit more to it. Diagrams have to be made, measurements have to be made and having the physical item to hand always helps.

I also no longer have access to the lathe I used last time. I need to rewire the current lathe I have got.

So no I can't I'm afraid. I've written full guidance on how it can be done.

If I had a working lathe then it's possible. But it took me a fair few hours last time due to the inferior tools. An engineering firm should be able to CnC it in minutes if you draw up a diagram for them.

[gareth_iowc]

Ok man thanks.

I've got a guy in mind but I thought you might be with a try as you've done one before

[Calum]

@gareth_iowc I wrote a guide on the basic theory. Follow that and you can't go too far.

Shit hot when ours should have a stand together at a show

[Mightyman]

You got it back on the road yet @Calum? Sounds sweet, show us some more!

[NINJA]

@Calum Looks cool bud, she's a bit smokey tho, was it a cold start???

[Calum]

@CYBER-NINJA It's a fresh engine, so that'll be the oil used on assembly.
@Mightyman Nah not yet. There is still a fair amount of work to be done. But it's nice that it's all back up together and can be started.

Hmmm i still cant decide which pipe to have off Romeu, i do like the look of the underslung one.

Sounds sweet though dude!

[Calum]

@finnerz89 It's not for everyone. I love it. But I love being different.

Just interested. I read you doubted the porting on the cylinder right? But it turned out to be good? Do you remember what it cost?

[Calum]

@irongamer727 I doubted the porting on the 3MB00P barrel. The porting by Mick Abbey is pucker. You want to get the head and barrel done together. 130 for the barrel 30 for the head.

[Irongamer727]

@calum wait, what barrel are you running? 4BL? What bike is that from?

[declan]

@calum do the porting/ head work people have their own specs or do I need to find out the squish and such

[Calum]

@declan You tell them what you want out of your engine and they'll tune it to your spec.

[Irongamer727]

@calum what did you ask for? Have you made your Dt unreliable?

[Calum]

@irongamer727 I just asked for more mid range power and to be more like an mx bike. You are always going to have to appreciate that reliability will take a hit. But the key is maintenance. And no, I don't think. It has caused any issues. Barrel has been ported for 4 years. Rode it daily door two years haven't been on the bike for the last two years but its there ready and waiting.

[Irongamer727]

@calum I mean for £160 it seems like a pretty good way of tuning your bike. Wounder if anyone could port my Athena. Seems to be much fuss about it.

[Calum]

@irongamer727 The issue is, it's not just the fueling you need to consider.

The standard DTRE ignition curve cannot make use of the new power, you need an aftermarket ignition system to go with it. Furthermore, you want to get the barrel ported with an exhaust in mind so that the new setup can make use of the exhausts harmonics. To top it off, you need to modify your fueling to compensate the better flow. Throw in the air intake for good measure, means it will cost you more than you think.

Even with the Athena kit you would want supporting mods.

@calum nothing is as easy as it seems.
