[TRI-Zbrian]

hey guys i need to know or have a good idea of the jetting specs i should have done to my carb for my tri z 250....

it has boysen power reeds, and a K&N air filter other then that its pretty much all stock.... im going to be bringing it soem ware to have the jetting done on it if i cant figure it out on the net, right now it runs pretty well but only with the choke on so there is def some things that need to be changed on it because id like it to run right with the choke off... and i herd there are alot of little things that need to be changed to make this carb work on my bike.... i know there are other peeps on here with the same carb on the tri z so help me out if you can please.

if the rest is all stock i think that 38 is too big. a 36 would have been a better choice. bigger is not always better. your parts should all complement each other. For sure you need a better pipe and silencer and i would recommend dumping the stock air filter set up. that would make the bike breathe much better and help get the most out of that 38. jetting is variable to the weather and where you live so any recommendations would be a guide line only. but if you have to run the choke your jetting is way too lean. ( go bigger)
