Crazy carb tech...

Has anyone seen one of these? Step price for experimenting, but I like the idea of no jets.

Yes I’ve ridden a metra 80 at a track that had one of these exact carbs. Bo said to order it with over 4000 feet above sea level settings regardless of where I live. Really they work on bikes with higher rpm motors. I was just in the pits with maybe a quarter mile run just fucking around. They are pretty though.

There's really no experimenting, Lectron has been making carbs for so many years they are proven to work.

I think that the venturi on that is either 28mm or 32mm, so you better have a bike that can pull it.

But yeah, the metering rod tech has been proven to work. Just a very expensive buy when you have people on MA who won't spend that much on an entire bike.

Re: Crazy carb tech...

The one I linked to says it is for a 65cc husky kit. I would totally send emails to the folks and see if I can have them help me figure out specifics on a carb, but if it runs a 65cc kit then it in theory would run a 70cc kit right? The displacement is the same, the only difference being that the husky is going to be a 5speed where you can hold the rpms in a powerband and make the most use of the carb.

I guess the biggest concern is the low end on there with a single speed non variated bike. Also would it end up having issues on a piston port setup vs a reed setup which most motos would be with this kind of carb on.

Too cool honestly. Might have to save up my pennies to try something fun like this. I bet it would be the same mount as a phbg and I would be able to use those I takes.

It's no the displacement that is an issue, it's efficiency/output.

The modded Husky/KTM 65's are making nearly 20hp. There are little to no moped cylinders in the bore that are doing that, even with the rest of the parts.

These carbs meter using vacuum wave/response, so the less efficient a motor, the less effective the self-metering is.

AFAIK, it's PWK size OD on the spigot mount.

Re: Crazy carb tech...

Dillion! Thanks for all the knowledge! All of that makes sense.

wait a minute, here in holland there are actualy 70cc puch's with 21hp, air cooled

What percentage of all 70cc puch mopeds that are existing in Holland are 21 hp?

Like, honestly. Are we only counting what you and the group of Dutch tuners in your community have built in terms of the national average?

No, I don't think that 21hp is what even confident tuners are getting (or even looking to get) out of their maxis. You can equate that to an American vs. Dutch thing if you'd like.

Re: Crazy carb tech...

My R45 is 400+ lbs and only supposed to make ~26HP.

It confidently pulls me up to 85mph and the spec top speed is 95 mph.

I doubt it’s making its top stock HP anymore.

I realize horse powers aren’t the same as torques. And comparing 4T to 2T isn’t a direct comparison. But something just seems way off here.

I even watched the racing video that Bas posted in that other thread. The speedo topped out at 47 mph in the straight stretch and the acceleration wasn’t that crazy.

So, I’m not trying to start a fight, but this stuff just doesn’t seem right to me. I know what 20-25 HP feels and looks like.

What am I missing?

Seemed like a mikuni with fewer steps, but that is why I am asking the questions.

Re: Crazy carb tech...

Someone else makes a lectron style carb but also in a smaller size to work on mopeds. Also cheaper but not as cheap as a regular carb.

Cant think of the name right now.

Re: Crazy carb tech...

Re: Crazy carb tech...

Seems like the KTM 65 SmartCarb is more expensive than the Lectron for the same price.

Re: Crazy carb tech...

Not sure, I didnt think lectron offered a 25mm or a 28mm?

25 would probably be perfect for a moped.

Ha . Thieves would steal the bike just for the carb , being as you could buy a couple bikes for what they think they want for the carb . Crap you could buy a very nice carb for what they're asking for a rebuild kit .

I know I'm 'thrifty' , but , those are simply stupid money .

Was just joking ;)

If i would choose between lectron and smartcarb, defenitly smartcarb, lectron is expensive to buy, but also very expensive to tune with the needles.

Rotary valve, smartcarb

Drag bikes not daily rider

Doubtful if anybody could make a air cooled 70cc 21hp daily rider puch moped in Holland that could stay together for use day in and day out and it’s not is it worth trying to make one either because it will just be impounded by policia and crushed,

Drag bikes and race bikes are cool but having a fast and reliable daily use moped makes the daily commute fun.

Definitely did not read joking, so my bad. I am sure the language difference isn't doing us any favors.

I would agree though. If you look up the history of Lectron/SmartCarb, they were both designed by the same dude. The Lectron design was sold to a major auto manufacturer and then the inventor went to build the SmartCarb afterwards.

BIGGEST advantage to SmartCarb is the ability to tune the metering rod without taking the carb apart. Obviously, with external adjustment points to main tuning parameter, comes the chance of accidental bump-tuning, etc., but either way it is convenient.

Re: Crazy carb tech...

You should've put lectron in the title, it'd get the attention of the folks w actual experience with them.

It seems like you can make em run and run well, but also theyre expensve and I think the main reason people with them feel so strongly that theyre worth it is they've got to tell themselves that a lot to justify a carb that costs as much as 2 or 3 whole mopeds. Smartcarbs anyway, they're what like 600 bucks?

One time we were at a swap meet and bobby got a gokart briggs motor for 75 bucks that had a lectron on it, helluva score, I dunno what he ever did with the carb tho. probably sold it, cuz even in hand I think i'd rather have the money it costs than the carb itself.

Re: Crazy carb tech...

Will,

I should have put lectron in the title. I do like where this thread is going tho.

Thanks for the info!
