As I was about to replace the factory intake manifold again, I noticed the Teflon intake costs almost the same as two OE ones... and that it and the Mikuni fuel pump are like a match made in heaven. Its got two vacuum ports, one fat one for the fuel pump and a smaller one for the valve on the carb. The OE pumps are known to be barley able to do the job, and if it were ever to quit on me I'd sure wish I had paid $30 for a better fuel pump... so I did.

I kept reading threads on installation issues for these, so I thought I would share my efforts and results.

I should start by mentioning this scooter is a less common engine and frame style - its a 1P57QMJ on the larger touring frame you usually see 250cc motors in.

First, from reading on here I knew the intake was slightly big for a factory size 24mm carb, but I'm a crafty individual so I wasn't worried. Luckily I found a perfect thing to use for a sleeve in a box-o-junk at my work full of 'might use that for something' stuff we save.
I really wish I could tell you where to find one, but I can't. I can tell you what it is though....
When we get new radiators to install in cars, they come with caps over the hose and line hookups. Sometimes plastic, sometimes rubber, and I found a rubber one to trim up and use for this. My other plan was going to be to layer up some 35mm shrink tubing on the carb, if that exists. It looked like you could just crank down on the thing enough to hold it, but I didn't want to risk an inferior seal.

That's a cool looking solenoid... It probably feeds power to the rest of the bike from there. The cheaper solenoids are different and have an exposed small terminal (or 1 or 2 single wires going in) for the crank signal, but you'd have to figure out what wire that is for yours, so you're right, its probably not a good idea to go jumping things blindly.
You could still try bridging the two fat posts with something thick, that won't hurt anything, except maybe your hand if it gets hot and burns you!

If you can pop your start button out and see the wire colors, it would hopefully be the same at the solenoid so you know which one to probe.

Sounds like you already checked the battery, but I had my negative wire come loose on mine once - it made a good enough connection to turn the scooter on, but no dice when you tried to crank it.

I like your Roketa btw... something like that is what I plan to buy next!!!

No, that still leaves the solenoid, the starter, the start button, the brake switch, and all the wiring in between.

Spark plug, coil, stator/regulator have nothing to do with cranking.

First thing I would do is probe the small terminal on the solenoid to see if it gets juice when you try to start it.

Here is a better look at an Avon




Another shot of the muffler with added bracket




And a look at the new air filter with a splash guard on it. You have to look hard, but you can see it. Its facing the wheel where water would splash off the wheel's splash guard.
Also note the support and bracket for that end of the intake tube, I improved the old one since the previous pic of the intake tube.



Attached is an item listing image of the filter

The enricher is like a reverse choke, instead of limiting air, it dumps in fuel. You can unplug it, remove it and shove the plunger back in all the way, make sure it doesn't drift back out on its own. Re-install it and see how the cold start does!

and did you drain all the gas out of the tank to replace with fresh??

I have a similar tach on mine, the default setting is definitely the wrong one, lol.
Nice scooter.. I wish mine was still shiny like yours!
