Curious if anyone has had any luck with running these . I have a 2019 850 and currently running Indy dan kit with no issues and ran across these weights
Epi Belly buster pro weights
- Thread starter snow1barta
- Start date
I used them in the 800's and really liked how they hit. Not higher engadgement but arm pulling accelleration. I think they contributed to premature clutch wear. They made an agressive motor more so, but with the 850, it is refined and hits softer on the bottom. I think they are exatly what these 850's need, only I have gone in another direction. I use the Promag weights as they are about the same price but adustable with the magnets. Early Promag had short lived bushings though. The new ones should be much better.
I've been told after a certain weight (68 grams 0r so not sure) the belly buster portion is no longer present and the meet the stock 10 series weight profile. I been using these weights for years.

Pro series are new design I am told by Epi same profile but more mass in belly . They look like a Boon Docker weight but not adjustable .
Just got some will be installing soon

I guess when you have a great product, everyone else copying you is a compliment? Seems like every weight manufacturer now jumping on the “copy MDS” bandwagon.
Who is MDS?
I havent hear much from them lately, but they used to be popular in the Arctic cat crowd, they bought PAR heads too i believe

Oh those guys.
The PAR head that reduces performance ??
I had one and went back to the stock head……….

I tested these last year and they are extremely responsive. The dont load quote as hard as a comparable standard belly buster or polaris 10-68 series, but the backshift and mid range is strong. Depending on elevation, we ended using there 70 gram weights with my helix and spring combo for 5500-6500 feet.
Pretty hard to beat the Indy Specialty Turbo 3 weight for the stock N/A Polaris 850 at sea level ( Makes your arms hurt ) ?
OPPPPPS ! Sorry I am a strong supporter of Indy Specialty ?
I couldn’t resist ! ?

Speedwerx is also making an MDS copy like EPI, adjustable though. Personally, I’d only buy adjustable.
Take a look at the Ibexx weights. lighter weight so response is amazing. Ibexx.com

MDS is alive and still kicking with kits for Cat, Polaris and Ski Doo we're still a smaller company that still offer our money back guarantee and have new products such as 22 Adapt kit for the Cats. NA or Turbo we offer what we hope our customers come to expect from MDS Clutching. Copied? yes, and they know who they are guess it's a compliment. Remember go with the innovator not the imitators. www.mdsclutching.com or call 509-899-0605
