sounds like you need a banshee

That is a hell of a thing to say to me John.

I noticed you're very particular about billet parts, but not particular on the material.
That makes all the difference in strength.
Billet CAN be stronger than forged, but only if you use very particular metals and heat treating.
For the most part, forging parts of the same material (assuming said material can be forged) win hands down compared to machining from stock.
Forged parts have grain flow, which adds considerable strength and reduces stress risers.





Problem with forging is that you need a large market to distribute the high cost of initial tooling...but once the tooling is in place, you can make thousands of parts rapidly and at a low cost compared to machining.
So while I'd like to see forged parts, it's not a reality and we have to settle for machined or cast parts.
The only way we could get forged strength out of machined or cast parts is by using superior materials that are compatible with the process, so that's where you need to focus rather than which parts to make.


Transmission gears and components out of maraging or trip steel, bearing supported rear brake lever, lightweight cushion lever for the 250, titanium axles and steering components, redesigned cylinder with nikasil plated aluminum bore as opposed to steel sleeved, and an externally adjustable stator plate to retard timing for starting.
That by itself is probably way more than what we'll ever see built for our LT's.

Why not just pop the sleeve out of a stock cylinder, bore to the next available piston size, nikasil, BAM. Instant nik'd big bore.

Forgot about the skirt..... I'm a ra-tard......   I think an aluminum/nikasil cylinder would be an amazing improvement for these bikes. Less friction, easier on rings and pistons, and you don't ever have to worry about running out of bores.
The only downside to it is when you want to have it ported you would have to pay for to have it recoated

Me's bring this back! 
So how would we even begin to find people to make billet trans gears and lots of other parts for the 250 so they can possibly made into a reliable 330 and larger?
I will make this reliable 330 happen one way or another!

Hey! First off this is a ZILLA conversation.   
Second.

Well then Kyle  .
Me has a plan for making quick change clutch cover, Im already taking care of the shatty rear brake lever. So now we need to figure out billet or forged clutch basket, hub, pressure plate for my 86  . Then we move onto the shift forks, drum, shaft, and who knows what else. 
Kyle this is the perfect project it wont get any better than this one. 

Settle down Beavis. 250's are welcome here.
Quick change clutch cover? Simple. You'll need 2 covers, a mill, a cuttah, a welder, an o-ring, and some bolts. But is it really needed?
What about the brake lever?
All that stuff billet? Gonna be $$$$.
I've got the basic LT380R plan done for you. Still need to work out some crank pieces, and measurements would help in other areas, as in seeing if the cases can be mutated enough to use a bigger yet strangely similar cylinder. The problem is that slant. If it stays, the piston/transfers won't line up. If it goes, the frame tube is in the way. I'd rather screw with the frame.

Yes the 2 piece clutch cover is definitely needed so we don't have to drain coolant EVERYTIME you wanna get to the clutches

...who's feeding trolls?

DP, I am working on the Reliable 330 that makes good hp it's closer than you think. The reliable big bore was the first step........   I will warn you it wont be cheap, like some of the others in the past.... These aint no HONDA....  I have not had any company bite on a run of stroked cranks.

LOL
