Tobynblevins Posted November 13, 2019 Report Share Posted November 13, 2019 I orderd ported cylinders they come with vitos pistons. After ordering guy msg says he is out of the cylinders I ordered witch came with wiseco pistons.... I did not think about asking what kind of port was did to the cylinder till after he shipped.. he did msg back and let me know he did not know what port was on cylinders because they was already ported.... just told me to up my 280 jets 3.. is that true do I only go up 3 jet sizes on a port I know Nothing about if so what would be 3 sizes up from 280 lol Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 13, 2019 Report Share Posted November 13, 2019 What would the rest of the set up be? Any way you can post a photo of the bottom of the cylinders in the transfer area? That’ll typically tell the tale of how much air you can use. Quote Link to comment Share on other sites More sharing options...
SKEETER Posted November 13, 2019 Report Share Posted November 13, 2019 I'd order some clues. Quote Link to comment Share on other sites More sharing options...
ginger Posted November 13, 2019 Report Share Posted November 13, 2019 should have just sent your cylinders to a good person who would bore, port, and give you all the info, and you would know your port is for the type of riding you do.

I just have a dmc pipe with 28mm koso carburetor but I'm switching back to stock it's hard to sink and tune them. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 15, 2019 Report Share Posted November 15, 2019 Definitely ditch the Koso’s. Quote Link to comment Share on other sites More sharing options...
