4L0-01 Carbs standard jetting?

[jamesieboy94]

Hi, im just wondering ic anyone here can confirm what the standard jetting should be for the 4LO-01 carbs?

The bike is a 4Y3 import from canada, i have fitted short can microns and boyesen reeds, standard airbox, im trying to set it up properly but im not sure if the current jets are the right ones for the carbs, as when i bought the kits a few years back, i wasn't aware there was different set ups, so if anyone can tell me what the standard set up should be, at least then I'll have something to work from.

Thanks

I am too young to have been around at the time, my dad having parted with his LC in 1987 or 8, just a few years before i was born, in anyones experience, did running microns and boyesen reeds cause need for a jet change? Mine is a bit rough and four strokey upto about 6.5k revs then off like shit off a shiny shovel haha, whhich according to akll ive read is about right for microns, but i was wondering if upping the primary jet a bit may help it a little?

Xavier's site RD350LC.net states that RDLCs have specific configurations for each country, notably in North America, Brazil, Switzerland, etc., due to noise levels and pollution. To be verified.

Also note that some aftermarket carb kits are very poor quality (Keyster/Shyster), so if you have used these, you will need to replace with good quality items from Motocarb or Allens Performance.
