I can't say I remember the twin pipe CZ. Back then most events I attended were observed trials. I remember AJS, BSA Victors, even Harleys dabbing through a mud puddle. Your fenced in corral looks like a great place for horses. I'm sure a lot of us are glad you're into bikes instead!
I knew it was a CZ and I wrote it, but I thought it was the 360cc... huge mistake.. Great bike not known to everyone, a bit like our Italian motocross bikes of the past. You are a legend boy, keep it up Cheers mate🍻👍
A dear late friend that I knew had a 1965 CZ 250 MotoX. He would occasionally let me ride it. I can tell you, they were awesome machines in their day. The suspension was tops in their day. I believe they were the lightest in the 250cc field. When the Jikov carb started giving up on him, he started calling it the jackoff carb!
Hi great video I am restoring one right now my dream machine and I have also 360 twin pipe and 360 side pipe 250 falta and 250 enduro. I born in Czechoslovakia and CZ an Jawa its my pride and joy of my collection.
Awesome bike! Jikov carbs were often referred to as “carbonators” for frothy fuel delivery. As far as starting a CZ the ritual was to flood the Jikov, start the engine, then lean the bike way over on it’s side to keep from flooding the engine while it burbled and choked before clearing out. Just part of the deal. I love these things, especially the 250 Falta and 400.
Great old bikes!. But is seems like any old two stroke bike video, they never let the engine idle. Seem to always keep reving it a bit, and all you hear is piston slap echoing. Maybe warm it a bit before reving it, that piston grow and quiet down. Then lets see if it idles..
The rear sprocket on that bike is huge. Must be a torquey little beast. I dig that woodland compound you've got up there.. is that Northern California or So Cal?
Well, if you are talking air flow and horsepower, then yes, the Jikov is better. But, most of those old Jikov's are completely worn out by now, and the Mikuni VM with its chrome plated brass slide is an easy replacement. The Mikuni has the ability to be fine tuned much more than the Jikov, but you could wear the Mikuni out by changing the jetting over and over again to get it jetted correctly and making power. Fortunately, the CZ guy's have figured out a very good baseline jetting for the Mikuni's over the years of Vintage Motocross racing here in the USA, and that why so many CZ's are fitted with a Mikuni carburetor these days. Are they better than a Jikov? Well, yes, they are better than worn out Jikov!
@@allenwenzel7272 I just have a hard time believing the Japanese made Mikuni isn't better. I have two VM34s sitting in my room right now I'm putting on my bike early next year hopefully. Going to run UFO (thunder products) slides and possibly their thunder jet. Didn't know they don't like being taken apart. I did remove the springs so they don't get weaker during storage. They definitely make more power than OEM CV carbs are way more modern bikes.
@@Whitejesselink I think you mis-understood the meaning of my comment. It's not that Mikuni Carbs are difficult to take apart, but that with the wide assortment of "Brass" available for the Mikuni's, unless you have some sort of baseline jetting recommended for your particular motorcycle, you could potentially wear the Mikuni body out by changing the jetting so often as you inched closer to the right configuration. VM Mikuni carbs where the mainstay of the Four-Stroke performance companies of the 1970's and eighties (Powroll and White Brothers, as an example). What bikes are you mounting your VM34 Mikuni's onto?
@@allenwenzel7272 a 2005 I think is, can never remember might be 6, Vulcan 500. It's a classic engine even though that's sort of new use to be the Kawasaki 454 LDT just bored out and same thing nearly just cams and carbs and engine covers as the ninja 500.
@@allenwenzel7272 slowly piecing the bits together. This is my first time doing a swap like this. Thinking of keeping the 35 pilots and trying 190 or so mains. Any advice I'm reading, or suggestions on someone to ask about this. It's the go to carb for ninja 500 builds but those aren't common, though findable easily online. But I haven't seen any jetting information being given for free just one guy charging an arm for a kit. Kit I'm piecing together will be better hopefully but yeah the jetting is tricky. Been reading and watching stuff on this of months daily it seems.
Got to ride one of these back in '76.....great motor. Ended up buying a '75 MXB 400 Yam as the monoshock was so much better.

Previous owner had horses… we have gas powered horses 😆
Hi man, the bird probably just likes bikes, he can hear you and is just joining in, pucker moto crosser, always good. Cheers 🥂 ☺
Haha totally!
The Eastern Europeans knew early on how to build a tuned two-stroke, this one is a beauty, thanks for showing 👍
My pleasure! Thanks for watching!
What a beauty… keep such vids coming bro
Thanks so much!
my late uncle gave my dad his CZ 400 in 1971 when he left for Vietnam great memories
I knew it was a CZ and I wrote it, but I thought it was the 360cc... huge mistake..

Cheers mate🍻👍
Thank you so much for the kind words Bruno!
My Dad had a CZ 250 back in the early 70's. My Uncle had the 400...

Sounds amazing!
another great ride. love this series
Thanks Jeff! So happy you're enjoying it!!
Blendzall the smell of castor bean oil🫛 and Pilzner, on a CZ and /or a Maico! Moderation of course on a course. 😅
Haha! Good stuff!
The twin pipes are awesome! My uncle bought a CZ 250 in the 70s and it scared him so much that he returned it. It was so much faster than his mx125.
They’re super fast!
@@wheelhousegarage It was before I was born. My dad and uncle both talk about it though. Apparently it had a rather abrupt power band.
Montesa también utilizó 2 escapes para un solo cilindro en algunos modelos de los 50's y 60's como la Montesa brío 80 (125cc) de 1954
Rear sprocket is as big as a pizza" braaap braaat burrraaap roost trail mix"

Great insights! Thanks for watching and sharing Erwin!
Great bike, even greater beer.
it almost sounds like a twin cylinder with those dual pipes.
У меня сейчас есть cz250/513 и хоть она 1985г она в отличном состоянии🔥🔥🔥👍
Nice!
When cresting a jump, gas it a little.

It idles very nicely 👍
That must’ve been a monster back in the day , on the track🙄
Certainly feels that way!

Thanks Dave! NorCal in the Sierra Foothills 👍👍
How is the VM series mukuni not better exactly?!
