900 miles per belt

[Soupy]

OK, DON"T shoot the messenger. I stopped by a Yamaha dealer on the way to the cottage Saturday to discuss pricing on the upcoming 2019 SRX. Talked with their service tech to discuss the issues he has seen on the Sidewinder series. He also indicated that the Yamaha rep that reviewed the upcoming 2019 models with him/dealership advised that there are revisions coming from Yamaha for clutching. Specifics were NOT given at that time so we will have to wait and see if info is available at the upcoming "sneak peek".

Probably a new primary spring.

Diff clutches so they would have their own sweet spot. Likely completely diff then ours as they may measure them diff then we do and obviously diff sheaves are diff thicknesses ect ect....

IMO cat has better belts avail....but others scoff at me for thinking this.lol

Dan

Better belts for sure.. Pricey but better indeed

2 more belts last wknd, up to 18 now. Your lemon's not a lemon, especially if you REALLY ride the thing!

18 belts? WOW thats crazy. I know you have probably listed your set up, but could you do it again? All clutching, studded? boosted? and do you hammer it all day? Not saying you shouldn't . Just cant imagine blowing that many.. What belts are blowing? Something is off on your clutching/sled

C to c 261
Tried all diff offsets, helixes, weights, springs, bushings, etc
Studded 144
280lb rider
Boosted 280
Blown 4 diff belts, including 8dn
Belts are delaminating, way too hot
Priceless Performance tweaked some stuff but no help. Wanted to put it in his chassis dyno but he didn't have the right drivers

I'm open to any suggestions

have you tried the hurricane alignment tool.... tried it on mine.....had to remove 3/16 off the back of the secondary to get spec with tool ....all seems to be good now...no belt dust at all now...... before all it took was one rip and the dust was unreal...I'm not 100 % sure but my offset is very close to 64 mm...give or take a mm.....3 runs this pass weekend back to back to back....122,119 and 115 and no issue

I have a machined secondary, tried it all, not down to 54 but as low as I can go without hitting the chassis. 54 seems super low but glad it's working for you. I set mine up to be straight at 1:1, don't think I need the hurricane tool for that. I also don't think the hurricane tool yields a 54mm offset, fyi. Most are saying around 57mm when set up with that tool.

Gone

 

[Soupy]

I think you mean 57mm? 67mm is way high

Youre right, oops! Edited.

Man your struggling with this belt eater. No pun intended..
Something has to be binding or hanging up on one or both of those clutches. That is to many belts.. And the 8dn is one tough belt, so if your blowing those?
without you mentioning every set up .. I would guess is might actually be something obvious.. Sounds stupid and in no way saying its you or your ability to figure it out.. BUT i know I have missed the obvious at times.. You know you find it and you go "wow how could i be so stupid"
You ever ride the UP? if you do or did frequently I would be willing to work on that belt monster.. I do not have a heated work space at my cabin (UP) YET but will soon..
I put 4800 miles on mine at 250-255 HP.. Granted I have more studs and a lighter weight, but i have been running about the same set up for clutching.. I have listed it on here. I run VERY light weight with the Heavy hitter weights.. lighter then most..
You have tried many set ups i would bet..
Some do not believe in the lighter weight steeper helix/straight helix ..
Some will and do remember some of the clutch kits that worked very well in the cats.. These were extremely steep helixe and VERY light weights. Not saying this is the answer by any means

Oh well

If the clutch is out of parallel the offset could be a crazy number when using the Hurricane tool. Remember it's not just setting offset at any given number. It's making sure the secondary sheaves are lined up to the primary.

these things keep getting more power, maybe its time for an Allison drive train

 

[fatchance]

Soup if your having problems checking your parallel this tool makes it easier. I have one that’s aluminum but similar. The offset with this tool will be wrong but you can still use it to check parallel. I will throw it on and take some pics tonight.
The Hurricane tool is useless, it does nothing to address parallel. Offset is very easy to set with a ruler, so it’s a waste of time.

But it does. If the Parallel is off the tool would not line up with the primary. It is running the line of the belt

 

[fatchance]

I understand that parallel can only be truly fixed by moving mounts, but this will reduce a dogleg if it is out of parallel.

Not seeing how that works in his video. He only references offset.
