@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 A multi coloured engine - unusually sweet! VHSB 34mm carb is it? And did your carb come with that top cap or did you source it from somewhere???
-
@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.

@calum I'll dig mine out and post some pics for ya, have to be on Sunday tho, as I'm out all day tomorrow.

@calum you are right though at first I was like wtf is this guy on about them I realised the price of the unit and I noticed the bad bits for the price I’d expect a way better finish on the metal are you sure it’s not a Knock off don’t mean to be a dick but it happens but I’m guessing you brought from pjs? I just realised it was not brand new you did a good job at cleaning lol.

@declan Yeah, it's stamped in the side as a VHSBLD which is what I wanted.
The thought crossed my mind.
To be honest with you, I can tell the carb is legit, I'm just surprised how bad the casting is.
This is the bike it came off.
As you can tell, it looks to have been tracked.
More importantly though, that body kit is on eBay.
It's a one of a kind, complete Carbon Fibre fairing kit.
You can't buy those, that's been specially made.
If you got the money for that, you got the money for legitimate carbs.
So no, I don't think it's a fake.
Now, that said, I don't actually like that body kit. But still impressive.

@calum I actually like that kit, it would look much better cleaned up, as stated in the listing. Cost £800 new and he wants £500 for it now, that's some serious cash for a kit, but as a one off it could look really amazing. I would add some tasteful decals to give it some colour here and there, but other than that she looks damn sweet.
Mine is also a VHSB LD carb, I may have a bit of time in the morning to take a couple of pics. Dellorto carbs are all made in Italy I believe, so there quality may not be as good as other countries???

@calum that’s a nice bike I personally like the kit Is there any tracks near you I did watch a video a while back of you track riding a yz 125 unless I’ve made that up lol

-
@calum is that an mx track? What I was asking in an awkward way was will you be taking yours to a race track
-
@calum You bought it used yeah? Sadly the luxury of returning stuff goes out the window when your not the OG buyer. All part of the risk with secondhand parts. Judging from the photo's on the ebay listing, the previous owner was not a details man and just ragged the bike. As it looks well used in those pics, but hey-ho you roll the dice and take pot luck I guess? Mine will hopefully clean up good and with a trumpet polish and new top cap she should be good-to-go!!!
