Well the install was easy as i had no problems converting from efi to carbs. I got a deal on some 34 mm carbs and they seem to work great so far. I have some questions about jetting. Does anyone know what jets i should run with a indy 650 with 34 mm carbs and tripple piped? Let me know. I don't know to much about carbs so be clear thank you.

[/quote]You are running 34mm carbs or 38 mm Carbs..... I have a 92 RXL 650 converted to 38mm with triple pipes a 280 Jet in the clutch and center cylinder and a 290 jet on the mag side of the engine. Depending on the altitude you have to either jet down...higher altitude (smaller jet)....jet up for lower altitude. you also have to raise or lower the needles according to temperature. ITs actually not that hard to figure out..... On warm days drop the needles to lean the mixture on cold days raise them so the mixture stays rich a few runs at wide open throttle with different jets should give you a good idea of where you need to be. Always start with a larger jet size and work down.......You save yourself an engine rebuild that way....I assume you know how to check the plugs for the proper mixture.that is that they are a light tan in colour.

Polaris never made a 650 with 34 mm carbs. Were did you get the boots? did the XLT boots fit the 650 cylinders?
The 650 with 38 mm carbs used 260 Main jets the same as the 600 XLT engine with 38 mm carbs, so maybe the 200 jets would be close for a 650 with 34 mm carbs. Either way be carful until you get the jetting dialed in.
