MOPED ARMY

figured it was that easy! so the dremel is for the spraybar? do you have a picture of what the spraybar should look like when its done? cant wait to try it out when i get around to rebuilding my bravo.

in his other thread he mentioned that he got alot of help from the dutch tuners.

Im sure they wouldnt mind the few pictures up on the wiki.

I received a bit of help from them too tuning my vespa and doing vespa research. they're a ton nicer than we are.

well, dude(shadow), if i asked "hey, where should i put this?" then i'd appreciate the opinon. but the fact is, A LOT of people don't use the wiki or know how to operate it. seriously. so we have a performance section for a reason.

just link this thread in the wiki for now, i'll get to putting the html in there in a little bit, i have all of the text saved.

and the dremel, use it to clean up the drill press mess. if you have any imperfections.

use a drill to go through the top of the spray bar, not the actual nozzel holes. sorry for not being clear

free mod = purchase a drill press = not free

last house i lived in was the house one of my best friends grew up in, and we rented it from his dad (who lived elsewhere). in the basement was a band saw and a drill press. oh, the projects we undertook!

Okay, the wiki is linked to this discussion now.

And that article is linked in this article and this article. break>

As for "A LOT of people don’t use the wiki or know how to operate it. seriously. so we have a performance section for a reason" well, I'm working on that, I swear. There are also a lot of people who don't know how to search the forums. :)

so wouldnt you just take 1.5mm off the end of the spray bar? so when it drops in place its right where it should be?

ok,what a fucking sweet ass tip.any1 think it will work on the kinetic tfr usa,03?

cAN i TURN A 15 INTO A 19??

I don't think he's asking if you can turn a SHA into a PHBG... I think he's asking if the 15.15 has enough metal to be removed from it to open it up to a 19mm carb.

There is not enough material in the body of carb to go over 16mm- drilling into 16mm leaves you with paper like thin wall on air intake side.

So the answer is no.

I am doing this jobs succesfully using hand cordless drill, good quality bits, standard table wise, good eye and steady hand.

Gradually going up in diameters and then polishing with rolled emory paper attached to drill and coarse steel wool also rolled into pipe like shape and tightened in one end with electrical tape to be able to hold it in the drill.

To take spray pipe out I carefully screw in sharp, tiny stainless screw and SLOWLY turn it in until I see pipe rotating (WD 40 a must!), then I patiently pull it out by screw with needle nose pliers, using it's conic shape as the level, moving up in thicknes as squeezing it - do not yanki it - the screw might get out and damage the end ...

after drilling I clean the passage for sprayer with matching size bit, I also drill with very tiny bit into the sprayer pipe to clean ridges from the screw.

After polishing into mirror like look all edges are smooth, throttle slide has to go in and out with ease, sometimes needs to be "trained" by pushing it in and out with screwdriver and a drop of WD 40 until able to get it out just by shaking.

Then I insert spray pipe back, making sure the holes are facing correct side and slightly tap it until it touches the wall.

Before putting the carb together I am using spray carb cleaner with straw to clean all shavings- by placing it in white plastic container i found out that at least 3 repeated cleanings are necessary to come out with super clean carb.

Sharp needle helps to make sure all tiny holes are not clogged.

The rest is easy, make sure rubber gasket and tip of float needle are plyable, if not get new ones.

Good luck, I could make some pics if asked.

i have tried this before w. a sha and a bing. usully comes out wonky somehow.

"any one done this to an fa 50?"

The FA50 carb can be opened up 2mm easily.

Same basic steps... However I used a mill and milled each side of the oval bore 1mm.

I have done a couple and it works well.

thinking of doing this. ideally you would use a ream right? i have access to a decent shop. i just dont know if i should do this now or wait until i have the polini 70cc.

can you bore out an intake manifold too? i'm cheap.
