Ratshee350 Posted September 23, 2011 Report Share Posted September 23, 2011 Hey all, I am trying to figure out what carbs to uprgade to. I have a .10 over stock cyl shee... a local shop drag port, cpi small bores, VF3's and 155psi compression with a coolhead. on the stock carbs with and airbox and a 340 main the things runs sick, think i even needed more jet. I got a recommendation to get Mikuni 34 flat slides! Now i just wanted to think about what some of you guru's thought before i spent the coin. I typically like to ride sand hills and flat out wide trails. Also at sea level. Thanks for any info... Quote Link to comment Share on other sites More sharing options...

RadarRacing Posted September 23, 2011 Report Share Posted September 23, 2011 Get yer stockers bored to 28mm , that'd be good to about 75hp. Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted September 23, 2011 Report Share Posted September 23, 2011 It's always best to consult with whomever did the porting as ultimitely they should know whats best for their motors/porting.. I would recommend 35mm range for a "drag port" 350. My .02 Quote Link to comment Share on other sites More sharing options...
Ratshee350 Posted September 24, 2011 Author Report Share Posted September 24, 2011 Thanks guys, I talked to my friend who did the port and he said 28's. He said he raised the exhaust port 2mm and opened up the windows and added the booster ports, The transfer ports are untouched. So maybe its not a real"drag port" lol.. Im looking to go higher on the compression also prob like 180 or so. Will a bigger carb be needed for that alone? Just looking for a little more info before i make a decision.. THanks again Quote Link to comment Share on other sites More sharing options...
camatv Posted September 24, 2011 Report Share Posted September 24, 2011 32/34 to 36/38 gas lectron. easy to tune. will produce more midrange than other 30-36mm carbs. Quote Link to comment Share on other sites More sharing options...
