Here's the story. I was looking to do a carb swap and have a few questions. I race XC so here's the details. The motor is an 85 with a ported cylinder. It's not a crazy port job and i don't know by who, but it makes a difference over a stock cylinder. Its bored .050 over and i run stock compression Pro-X piston. It runs great on straight 93 octane mixed 32:1. I run an FMF fatty pipe and power core silencer, delta force 2 reeds, UNI filter with outerwear and full airbox lid. Stock 34mm Pj carb with a 42 pilot and a 155 main. Now my question is, how much of a difference will there be by putting on a kehein 36mm PJ ? I know putting on a bigger carb gives you more top end, but im just looking for more power from bottom to top. And my last ? is, will a 36mm carb off an suzuki RM 125 work? Thanks, John
