I got a 05 summit with Ski Doo Racing Twin Pipes. What weight of pins do I run in my primary for higher elevation. I cant keep RPM's in 8000 feet and above and was told to run lighter pins. What gram do I use. Anyone know

If you have to drop weight from what you had you lost Hp
Don't drop pin weight....drop the pipes. The HO doesn't like twins at high elevation. Those race pipes are real finiky up high. I had a set of Crank Shops which are much easier to tune....got a single DP pipe for this season.
If you HAVE to keep them try a higher finish primary spring...160/380 if your running the stock 160/350.
Is your motor ported?

No from my knowledge my motor is not ported. I talked to 3 or 4 people and they told me to run hollow pins with no set screws. I rode it in Cooke City and Bear Lodge and didnt run that well. Went on a late trip to the Black Hills and ran amazing. Beat an XP all to heck but in higher elevation RPM's fluctuated up and down from 6500-8000 when in deep powder and on the throttle hard. FRUSTRATING! My buddy with an 05 RMK 700 highmarked me, was not happy. I would like to keep the pipes. Any other suggestions?
I would go back to the stock pipe, it will likely make more usable power and be a better choice for high elevation. And don't the race pipes run at a higher RPM than the rev limiter will allow?
