MOPED ARMY

sorry i cant find a 19mm clamp carb with a cable choke

if possible i want to keep the moped oil inject not mixed.

The choke on the phbg is kinda modular like, you can put whatever choke you want on it.

ok so i order the polini 19mm intake and a phbg 19mm clamp carb with the pull choke. and i heard to get http://www.treatland.tv/malossi-VL6-4-petal-reed-block-p/malossi-reed-block-stuffed.htm to change the power band and then the ninja to max out speed

woot! Another kitted chappy.

I highly doubt that four petal is just going to sit right in there without some modifications. I am using one of those $30 Top ones up on treatland right now (got the whole intake, just using the reed block), but I had to slightly dremmel open the intake on the cylinder (mainly square out the corners and widen the sides just a tad) and open the holes on the reed block to fit the bolt pattern. I tried setting in my gila reed block (same size as malossi) and it wasn't really very close).

I'm just premixing on mine now, with a 21mm carb (cable choke and malossi e12 air filter) and the gianelli pipe. Mine does a comfortable 45 and gets there reasonably quick despite my super fat jetting. The Ninja pipe has a huge restrictor that basically part of the header and really not very easy to remove unless you chop the header and weld on the one from your stock header. Other than that, the chamber is super nice and would likely rev out much higher than the gianelli (like a foot of header pipe).

I can't imagine what these bikes would do if they didn't weigh a ton. Luckily the bottom end is rock solid, so I guess there are trade-offs.

I dunno, I've always run a 21 on it. I think a 19 might actually be a little better, but who knows, the overall difference in speed is negligible. I have the polini intake that treats sells.

Not sure if the gianelli is better, but thats what I've used. I originally wanted the ninja, but then after seeing the two, I dunno, both are have their flaws. The ninja chamber is awesome, its just that header restrictor that sucks. If you know anyone who can weld, just chop and reweld the stock portion and it'll be fine. The gianelli also has a restrictor, but its just tacked in and comes right out. The header is way too long also, so my pipe is all low end, and basically sucks from 30 to 45. It gets there, just no pull.

If you want to get creative, get some other pipe and just weld it up to fit. I'd love to try like a ninja g2 or a simonini calibrata or even a metrakit giant muff. The stock chappy header is huge (same size as the aftermarket pipes), so any of these could work with a little fabrication.

lb80 rear sprocket is a little smaller. You aren't going to lose any torque up hills. My bike blasts most everything up any hill.

I would not keep the oil injection. While its unlikely it'll fail, the risk is just not worth it. You should do 40 no problem. I've hit just over 50 on mine.

yeah, why do you want to keep oil injection? premixing isnt a hard thing at all. plus even though those injectors NEVER fail, the chappy one isnt designed to inject correctly and high speeds.

not that premixing is hard im american im lazy. i can mix gas. does the carb get effected by running mixed. im assuming you just use 2 stroke injector oil.

I would seriously think about premixing. The oil injector is calibrated to the exact amount of fuel delivery of the stock carb. The fuel delivery of a 19 phbg is a lot more than the stock carb. Too little oil for proper lubrication.

If you are running a Polini go with what Polini suggested and use Sabre at 60:1.
