Hello just bought a b1 rep mini moto,
When I got it it started but needed a new carb,I've put a 19mm one from petrol scooter website,and had a lot of problems with it getting way to much fuel and running out every were to getting none,I've finally fixed it and now it starts really well and revs well when you lift it up.but when you sit on it and open the throttle it just bogs down but if you scoot along it will very slowly go but not much and only at walking pace.
What I don't get is I was looking through the holes on the clutch bell and I could see the clutch spinning but as I put weight on the bike and throttled it it didn't slow down it just span as before.
The previous owner said it had a new engine,and because of this issue I took the CB of and had a look at the clutch,it's a 3 shoe non adjustable but looks brand new,it did have a tiny bit of free play were the shoes connect tho.
I don't wanna buy a new clutch just hoping its that as I've already spent to much on this bike.
Please help

Anyone I no it's a rep but that's all I could afford,
I'm not sure if it's the carb settings as the old owner said he had no problems with the clutch

I don't think 3 shoe non adjustable clutches have a key way in them. Possibly clutch spinning on the crank shaft. Take it off and inspect the woodruff key

If you take the rear wheel off the ground it will Rev out and spin the rear wheel ?
But bogs if ur sat on it ?
Sounds like the clutch is adjusted wrong biting to early

Yeah revs fine if you lift the back wheel up,the when you sit on it there's just no power.
I really don't no if it's clutch related or carb,as I've had so many problems with the carb(that's new)seams like it's not getting enough air/fuel as I haven't got an air filter on but even if I place my hand near(not cover)the hole it bogs a lot worse even on the stand

Those 19mm carbs are ****. So many people have trouble with them.

Put an SHA on it

Having similar with my B1 rep read my posts Think you will find its a taper fit ensure the nut is tight Youd be able to see keyway are you sure you cant adjust it ?

i put one of those carbs on my 911 and its great.
sounds like it could be too much fuel to me.
mine used to do it before when i had too big of a jet in it, would rev fine on the stand but under load it would just bog down.

That was before,I found out it is adjustable with little Allen keys on the ends,it's now adjusted so the brackets are about half way up,it does bite quite high but that's how I want it as it bites really well

If it's not bedded in you want to wind the bolts out evenly a bit so it bits earlier

The friction material needs a few heat cycles to set in. Like bedding in new brake pads on your car.

Also the rep clutches have issue of coming unstuck if they get too hot.

Here's how the clutch is now but I'm gonna wind it in abit,as it bogs abit out of corners.
Was going really well till my friend got abit throttle happy and flipped it an snapped the foot peg mount
