Jetting on a 2007 ski doo 800ho
- Thread starter Harleywideglide
- Start date
Is the dpm still installed? Is the sled running bad?
I'm not sure what the dpm is. It was running okay but had low compression on the stator side cylinder so im doing a top end on it, bought the boyeson reeds because the stock boots were toast it did have a unbranded can on it that was loud as hell when i bought it, so I bought a ano stuff one. But even with the low compression it seemed to run pretty good. I just didn't want something else to go bad
Dpm is a altitude compensating device on the sled. They are jetted for sea level and lean out as you go up . It says stock is a 440 main jet. You might need to adjust the needle a bit with the reeds but other than that it should run with factory jetting.
Thanks alot really appreciate the advice
DPM varies float bowl pressure to adjust for both altitude and temperature. It sits above the carbs, a round black plastic case with tubes running out of it that run to the carbs. Can be tested with a 9v battery and paper clip - Dootalk will have instructions on how to do this if you're interested. On older sleds, the pressure lines will crack and leak. I know that all early renegades had it, at least. I owned two gades and four summits with DPM. Jets work the same, but be careful - there is little leeway if you have DPM between safe and lean when you rejet, especially at lower elevations. On summits with DPM I would only shim the needles to get spot on in the midrange - the rest of fuel curve was very good. When DPM fails it runs full rich. It was very effective and innovative - originally developed for the ultralight aircraft motors. First, confirm you have it. Should be a decal on the hood if the stock decals are in place. Doo's site will have specs for older sleds that should list it, too.
