I have no interest or parts supply to go through the process of fine tuning clutching . I am quite sure that my 24 RXC has more potential and would like to purchase a good trail oriented flatland kit . Finding a kit seems to be problematic . Speedworx ( coming soon ) and the few others seem to have had kits out long before they had any opportunity to test ( not a fan ) BD seems to only suggest weights when allot of the people with a decent amount of knowledge - experience suggest the helix is wrong for the sled . I understand that there is a limited  amount of people and miles put on but does anyone have a decent , tested setup ?

I've seen this discussed elsewhere and Thunder Products apparently is a good source as they've had more time on them.

The chassis lacks flatland high performance efficiency due to the belt drive...If the best aftermarket clutch kit tuners cant find a viable performance enhancement that should tell you something...Contact some of these companies and ask them point black if they develop their clutch kits with a CHASSIS DYNO, along with seat of the pants field testing...If they tell you that they dont utilize a C.Dyno....Check that company off the list and move on...It's unfortunate that you spent upwards of $20,000.00 on a 600cc sled and your disapointed in its trail performance...

At no point did you come close to answering the question being asked.

But thanks your useless info about track dynos (lol) and letting us know that anyone looking to improve performance is disappointed with their machine.   And that you're poor.  

I spoke with Terry from Thunder Products Clutching at Hay Days and was very impressed.  They did probably more flatland testing than anyone else.  I would recommend giving them a call.

Don’t even bother with their web site, calling them is much better.

@EBEAR - I agree on your assessment of the other vendors.  I have no doubt they will give customers their best effort, but all except TPC have been hurt by lack of snow for testing.

You forgot the air box mod

I just copy/pasted what was on their site... looks like the only clutching they could test and dial in last winter was out west where they had snow.

Get your hole saw ready. The air box mod is going to be next big thing 

It's still looks to me that for those of us who have no patience ( or skills ) for clutching that a flatland kit is a wait till mid winter and hope for some testing . I have found nothing available other than speedwerx 1.5 - 1.75 track option for flatland and I'm not sure what the difference would be on a 1.3 cobra . I don't mind spending the money for a good kit but not only to find " oops " after more testing this is better .

Frankly, @EBEAR I'd tend to wait as well. I know that there's a ton more fine tuning to be done to clutch the 600 and I'd rather wait for others to buy the various kits from performance shops, then get their feedback before choosing a trail set up of my own. I too am skeptical that anyone got enough trail testing last season to have it truly fine tuned.  

My EASY temporary Band-Aid fix for the moment to address the over rev issue will be to choose a stickier belt to see if we can pull down the over rev by a couple hundred RPM's. That Band-Aid will carry me thru this season until there's a more definitive way to dial in the 600's trail clutching.

Call Thunder Products Clutching.  Everyone else was stuck at higher elevations last year and needs a good season to get their flatland kits right.  But, Thunder Products have a setup that's pretty dialed in - they did a lot of work with the racers last year and are well ahead of the aftermarket.  Before you decide to wait, give them a call and actually talk to them in person to see what they can do right now.

I don't have a relationship with them and have nothing to gain by recommending them, other than just trying to help you.

I talked to Thunder products a couple weeks ago about my procross 600 that has an adapt. They have something in production for the catalyst (that would also help my sled). They said it was a month out then so I'd guess it will be available in a couple weeks from now. They described what they are doing but I'd call and get specifics from them.

He was out testing it on the road in front of his shop today.

I talked to him earlier this week. Production is a bit behind. I don't want to try to speak for them but it sounds like it's in the secondary where they found the most improvements.

i find "kits" can be hit or miss. every sled is a little different. i aim for target rpm and see how it rolls.

Changing my spring and helix made a big difference.  The primary is actually pretty close from the factory. What the catalyst comes with is trash. If the weather report holds true I should be able to ride in a week. I have some adjustable weights now to load it down. All stock vs a secondary change

What did you change the helix to? Are they 48 straight on the 600 catalysts?

It’s like a 56/49 and a stupid heavy spring from the factory they have used on all the trail sleds the last few years.  it doesn’t work on anything. You will want the 155/220 spring used in like a 2018 600 trail sled and something like 48 or 49 start with a mid to low 40s finish. This will pull the sled down under 8000rpm with the stock primary until like the high 80s and the rpm will creep up. All stock the sled is over 8k at like 65mph which is bad because it looses a lot of power over 8100 and you can tell. Weight wise you will probably be around 64 grams. The weather report is looking promising for me to ride and get some more time on it next Sunday when the trail opens. Keeping my fingers crossed 

My sled also has an alignment issue. I am going to pull a shim out when I put the secondary back on the sled.

Good weights.

As you start to pile some miles on, keep a eye on your buttons on the adapt primary. Not saying its a issue, but I have some SLIGHT concerns with how they will wear on the Adapt(with more miles). Specifically where the buttons are located compared to the team. Not saying its a issue at all, just something to watch IMO.

will do. Calling for 8 inches on snow now. Started snowing about 9am and we have an inch or so on the ground now. Supposed to snow heavier this evening. Should be able to ride this weekend and try them out

Nice!  They are calling for a nice dump this entire WEEK over your way. Also western area also.  Already better then last season just based on temp outlook. You need some heavy torsions off my RXC let me know?  Im pulling them in next week or so. They will collect dust as they way to heavy for me much less the wife on the RXC

Samething they are saying here for snow. I probably won’t need the springs as I went full retard and order ohlins for all 4 corners from Ian at monster. He called last week saying the fronts had shipped from Sweden on Thursday. He has the rears at the shop.
