Hey there new to forum with a bit of a predicament. Looking for some options I guess.
I've got a p200e with 210 malossi kit, with malossi reed valve intake manifold going into a Mukuni 28mm tm flat slide. What happened today was I got back from a short ride and when I got off scoot in driveway I saw a large puddle of gas at the rear. Pulled side cover and I saw the carb about out of the rubber manifold. Been having a pain in ass getting that to stay tight in the manifold, either it gets to tight and starts to pop up immediately or too loose, we'll it's too loose and won't stay in at all. Also the pipe that runs up the side of carb was rubbing on the cylinder and broke so that's were the leak was coming. Looked for a new part ( it's the plastic part) that broke and can't find it, so that carb is unfortunately useless now.

So my question is I need a new reed valve manifold block and I need to it too set up a little higher than malossi one on there now, not much just like 1/2in or so. I was thinking I could get someone to make a aluminum plate that thick and add it to mine and that might work. Or I could get the kit malossi has for the 30mm dellorto carb and new block that might be a little taller or polini has one that has metal tall bend one that you use a rubber sleeve to attach the carb with 2 hose clamps. I also see MRP is making a nice looking block for a 28mm or 30mm set up.
So my real problem I have is HOW to you keep any carb in the rubber malossi inlet manifold and what set up will lift the carb off the manifold so it won't rub on it. Sorry for the long winded post.

Loos like you have a spacing issue. These two red lines are supposed to touch so that the clamp can sit in the groove on the carb. I can see righ now the way the clamp is, the carb will get loose with vibration.

Is the carb hitting the frame when the suspension is fully compressed? If so angle the carb out of the way.

Next, check the rubber manifold for where the rubber ridge is. Does it line up with the groove in the carb? Adjust as necessary. These manifolds fit Dellorto carbs the best.

When tightening the hose clip, first move it as close to the carb as it will go.

Is the Malossi kit the original old 210 and un-modified?

The original Malossi reed valve connection can be a pain in the butt. I made an aluminum one and use a rubber coupler from a rotary valve manifold instead. Think SIP sells one just like this off the shelf. I still have to be careful with tensioning the clamps too tight seems to pop them off I've learned how much is enough.

This is the way. Sip does sell that alum piece, & other rubber couplers are available; or go get piece of radiator hose

@ dirty dave , that pic was just showing how loose i found it after just a short ride. I'm starting fresh got a mrh reed block w RD350 reed valve coming, with a Dellorto 28mm flat side and will attach it with the clothed rubber sleeve. I hope this solves that problem. Thanks for your responses 👍
I think I'll reinstall the Mukuni external fuel pump too.
