@calum it's going to be interesting to hear how she runs!

@irongamer727 Yeah sure, I expect it to be...disappointing lol. If I bought a rag around RS and bolted on a cylinder kit then yeah, fair enough. But having been building it for nearly 3 years, the expectations are too grand.

Another delivery of goodies arrived!
I think this is shamefully about all I can afford this month
Brand new set of mirrors
Now, I skimped out here. Samco hoses are around £100, but I got these from China for like £35
To be honest with you, they're banging for the money. Maybe I'll get the samco ones further down the line, although I doubt it.

@declan Direct from China, like alibaba style.
Engine built, I will clean the carb tomorrow to make it spanking.
Titanium bolts mount the intake to the engine. Along with my powdercoated skull cap, which should contrast nicely with my NGK racing coil and HT Lead, along with the red engine mount.
Just awaiting on some carbon from America, my on going Hydraulic clutch conversion, then this engine is ready to rock and roll.
And for those interested in the hydraulic clutch conversion, it would appear, after much discussions with far more qualified engineers, that the solution the other chap derrived is not adequate.
I will explain in a separate thread, but basically it's gone from being very easy, to needing a bit more thought...but more on that when it's finished.

@calum COOL I bought a job lot of parts for my MX and there was a 34mm Dellorto in there. It's a VHSB model but needs a good clean and a new top cap, as the plastic one's damaged. Those alloy caps are cool looking but cost £55 new. I think it's the flat sided version, but will need to dig it out and check.

Cant wait to hear it sing :smiling_face:

@jens-eskildsen You and me both, but we're a fair bit from that just yet.

I must say, I'm pretty disappointed with the casting flaws on this fairly premium carburettor.
Having properly examined this carb today, I've cleaned it up and noticed pretty bad flaws in the inlet tract.
I didn't take any photos, but see the flaws on the outside, imagine those all on the intake.
I read that polishing the inlet doesn't do anything (Graham Bell Two Stroke Performance Tuning), but he goes on to say, it definitely doesn't hurt.
I lack the motivation, skill or time to do this job properly.
But I did remove the flaws, which I'm pleased about. Gave the carb a decent clean and it's ready to join my engine.
@NINJA What's the casting like on your VHSB?
On my DT I run a VHSA, which was sold to me as "Blue Printed" So I quickly sold the one I already had and like a child bought that one. But to be fair, having seen the condition of this one, maybe the one I got on my DT was reworked.
