Mountain riding Dalton vs supertip vs thunder products vs stock lr.

[jeff catte]

Has anyone ran different brands of clutch weights Looking for feedback on clutch weights that people use in the mountains. Looking at a 270hp tune and would like real world feedback of mountain riding performance. I've searched the forums but couldn't find good comparison between the profiles for mountains, mostly trail talk.

The dtya-1 I think are a bit heavy for real mountain riding, I have the 275hp header tune and on trail it's fine around 8900 but it will pull down on a climb in deep snow. Stock helix and dalton black orange spring. I think the QAY-70 Would be a better fit for mounting riding. They adjust 70-77. I'm going to clutch rpm for deep snow and if it revs a bit high on trails than it's fine. I was loaded to about 76.5 grams and it was just to much in deep snow. Another thing is once your front intercooler is plugged with snow you are screwed, machine won't make any power. Running these tunes gets real expensive to make them work well, pretty much need a bigger intercooler or add the second one at throttle bodies.

Ok, thanks for the feedback. I might get the qay66 and run it on the stock tune for see how it feels.

honestly the factory tune is powerful, especially if you load the turbo more with aggressive clutching. Lund on here has the sweet set up for stock power. the heavy factory yamaha weights loaded up with heavy rivets, 73 grams, 35 helix. Search and you will find it.

How are you liking the hurricane 270 tune?

I have not gave it a fair chance yet, my closed loop wideband isn't working so I'm running it unplugged which is a rich tune and my clutching needs dialed in. Long story short, right it's faster on trails than stock and slower in deep snow. Waiting to get this closed loop thing figured out as the season comes to an end. Eventually it will be faster.

What clutching are you running now?

Stock helix, dalton black orange. DTAY-1 that were 77.5 grams. This was to much weight for mountain riding. Next time out I'm trying them at base weight of 75.

I pulled secondary clutch and inspected closely, without spring in. The helix is almost not touching 1 roller. I installed a dalton helix and it touched all 3 rollers very nice. I have a 42-36 dalton that should work good. also have a 33-35 coming. Clutching this thing for the trail is easy, different story in the hills. I have never clutched a sled that would rev on the trail in the sweet spot and fall 1k rpm on a load. Almost acted like it would not backshift but it worked just fine when machine was stock. Stock was pulling 8900 on trail and 8750 on a deep long pull with stock clutching. like i said the tune has not had a fair chance to make good power with the wideband unhooked, i know unhooked it defaults to a base map but what map? with it unplugged is it the same tune you get if you order tuning without closed loop option? or is it a super safe rich tune? i have a feeling things will change with closed loop working.

I'm still at a stock tune. I tried a Dalton black orange wrapped at 6-2 this year with new secondary rollers. I have a set of the qay66 coming and a black bronze primary spring. I'll try them empty to see what I get on a Hillclimb I like that I can adjust on the hill if I'm reving to high. I think I'm going to try a higher flow 2.5 exhaust and see how it runs.

That 8LR weight combo from Lund works the best hands down for stock tune with intake and exhaust. If i recall correctly 8LR weights with the steel pins, loaded to 73 grams, red/gold/red primary spring, stock yellow spring wrapped at 3-3 with the 35° helix..

I ran this setup for 2000 ish miles on a stock tune with CAI and a 2.5" pipe.. sled hauled #*$&@. Riding between 5500-7500' I Needed to load the tip up more to ride at home around 1500'. Pretty sure i added 7 grams to the tip for a total of 80grams.

Yep they weigh 73.5 on my scale. I might try them on my tuned winder, see how they work

Yeah I should have kept mine around for when I tuned it, ohh well I'll find some one of these days.

Currently running Dalton orange in the primary and orange in the secondary at 6-2 with 72 gram Heavy Hitters and I'm down 4-500 rpm at elevation.

They also don't have the snap outa the hole like the 8LR'S did.

What is your engagement rpm?

What is your engagement rpm?

3-3200.... engament is nice and smooth. Grenaded a belt today... pretty sure belt temp was the culprit... and I was having to much fun smashing pow.
