Best mod 174 3 inch track, worst mod, 10 pd lighter 174 3 inch track, absolutely no gain in track speed or any other advantage. Worst sled 2013 Polaris Pro, fun sled and awesome handling but by far the most expensive on repairs in my whole sledding career. Best sled prob my 09 M1000, bulletproof all around great snowmobile but I think my Winder will prevail as by far the best when I look back at this post a few years from now.

Best sled, 2009 summit x mod sled. My 2019 G4 is working it way into that slot tho.
Worst sled, 98 xcr 440 race sled.
Best mods Holz rear suspension in my 09. Enzo suspension in my G4.
Worst mod, Tried a SLP pipe in my 09, Absolutely junk, “Still Looses Power”

 

[JungleJim]

Best mod - MCX Turbo on my 2008 Apex, Worst mod - Porting & Polishing my '94 Polaris Storm 800 ending up in two cranks and about 9 pistons later... (when it worked that triple with triple pipes sounded AWESOME!) tied with putting 2" plastic paddles on it which broke off almost every ride... Camoplast paddle track was a great upgrade! Best Sled - 2019 Summit X 175 (all issues were self inflicted!)

Best mod was floating secondary in 06 Summit - never blew another belt in that sled, was not that bad on belts but such simple fix.
Head mods and clutch kit in 09 Summit - leaked antifreeze into motor on first ride, secondary blew up on second ride - zero give a shat from APP Shop.
Best sled was 02 Summit (could not kill it) but the 2019 Alpha is putting way more smiles on my face
Hmmm worst sled hands down no contest winner = 2017 Summit.....POS

Many good times and adventures with all of the sleds over the years

 

[Ballzdeep]

Best MOD - Raptor shocks or billet thermostat
Worst Sled - Hands down biggest piece of chit machine i have ever owned 08 XP
Best Sled - tie with 06 rev or 15 Freeride

 

[niner]

Best mods were a 156” track on my 99 summitX and a 174 track on my M7
Worst mod was nitrous on my 03 vertical escape
Best sled is my Alpha but my 03 vertical escape with Ralph’s case porting and twin pipes was a crazy fun sled.
Worst sled 98 SRX. My dads 98 summitX killed it everywhere.

Funny how your worst sled (2017 Summit) and Jungle Jim's best sled (2019 Summit) are almost the same other than track length. Shows either how far they came in 2 years or how inconsistent the build quality was. Or how different you guys are in your riding styles. Got to say fuel injection, although not a mod, has made these 2 strokes way, way better so anything after carbs is a hit for me.

Changes and consistency of build quality went way up from 2017 to 2019.
Almost temped to buy another Doo.

Isn't it strange how some times simple mods are just the best!

[neilsleder]

Best mod was RK tech head and pistons on my 09 summit. Had Deano do power valve mod and reeds and that sled ripped! 156 2.5” track and went good! Worst sled I had was a 08 800 Dragon. 6 motors in that pile of crap

 

[TDR]

Best Mod - Raptor shocks. Can never go wrong with them. The difference is insane.

Best sled - my 2019 850 Patriot 163 has been awesome. Now if I had the skill to ride it properly. Just going to have to suck it up and follow my boys more often.

Worst sled - 2006 RMK the steering in that thing sucked.

I like the idea of a Doo too but I would have to find the handling dramatically improved with the Expert package first. Time will tell.

 

[tmo1620]

Best Mod Speedwerx full exhaust with some custom mapping and clutching from myself and a few cat experts on my 14 HCR

Worst Mod MC express turbo on my 07 phazer mtx, ran like garbage 95% of the time but the 5% it was running good was fun lol

Best sled 18 mountain cat 153, still so much fun

Worst sled 14 m8000 162 limited es, heavy as hell and just died randomly 4-5 times a day at any throttle position, never could figure it out

 

[moyiesledhead]

Best mod - SLP pipe set, controller, and clutching on my M1000. That thing rocked!
Worst mod - Simmons skis on any of my M chassis sleds. Just plain dangerous! Worked great on my '97 Summit though.
Best sled - Tough choice over my M1000, but it's gotta go to my 2005 M7 162. Game changer in it's day, and my daughter still rides it.
Worst sled - 1981 Yamaha SRX440. What a POS! Went through clutches faster than fuel!
Runner up - 1972 SnoJet. Never could get that thing to run for more than an hour at a time.
