Is it possible to put the helix back on the wrong studs? I was looking at mine last night, I'm not much of a tweeker but mine does have the delay so I would like to adjust it and see if it helps.

Yes, the helix can be put on wrong.
You put one spring in the hole marked "3" on the sheave and the other end of the spring in the hole in the helix marked "3" and twist it clockwise until you get the helix lined up with the studs. It helps if you put the belt between the secondary and the frame of the sled. This will hold the moveable sheave out so you can get the helix on the studs easier.
How much twist are you supposed to have? Probably 60 degrees. When you take the helix off to check, you may want to make a note of the holes you are in.
As previously mentioned, some setups may work better with 70 degrees of twist. Then you would use the hole with a "1" on the sheave and the hole labeled "6" in the helix and twist clockwise to put the helix on the studs.

Thanks Mine was in the stock 3-3 position, I changed it to 1-6 it didn't seem to make much difference. I have 3000 miles on it does any one think my delay may be due to wear in the clutches?

I doubt it. Please describe your delay?
Did you say every thing is stock?
Is the delay worse when the air temp is warm?
Have you checked belt width and belt height in the secondary.

Len, It doesn't seem to be temp related, it was -10F the other night and it was doing it. I did change the belt back to a Yamaha from a ultimax XS and it looked higher on the clutch and did bog less. Everything is stock, no air filters nothing.
Thanks

What year is your sled? You may want to consider adding the info re. you sled, etc. in your signature. That way we can always tell what sled you are talkin' about.boneman said:
Did the sled always seem to bog? There is an adjustment for belt deflection/Belt Height. If you are not fairly close to the top of the secondary with the top of the belt, you may want to consider an adjustment. To check this, take the belt out of the primary and lay it in the secondary. The top of the belt should be very close to even or slightly higher than the secondary.
Where do you have the idle set at? We typically set it at 1500-1700 RPMS. This can impact you if you are chopping the throttle/braking and then looking to take off quickly. This setting is a bit higher than Spec.
Have the carbs ever been taken apart and cleaned? If they have been taken apart by someone else, you may want to verify where the clip is on the needle. If they have never been apart, they may need cleaning. Seems to me that I recall that carb float setting was also an issue for '03s. Not much has been said about this since the '04 model.
During shifting at WOT, are you seeing 10,200? I was not and took out the rivets in the tips of the weights. Now, she bangs right up to 10,200, drops slightly as it fully regains traction, and then tops out at 10,400. While a I gave up a few MPH at top end for this, the sled is much more responsive and accelerates faster. Also, I noticed a considerable improvement using the White Secondary Spring at 60 degrees, over the stock secondary spring at 60 or 70 degrees twist.
Are you sticking to 87 Octane fuel. The higher you go the crappier they tend to run. Do you have any other reason to suspect fuel quality?
Have you inspected the coils? You may want to consider removing the rubber from around them and reinstalling them. Fire the thing up in a dark room and look for arcing down in the coil well. If there is arcing, they probably need to be cleaned with BrakeClean. Inspect the coil-side of the tips of the plugs for arcing also. The '03s and early '04s had some trouble with this. They changed coil design to address this. Late '04s and newer have a different coil.

Len, Thanks for the info, I will be making a belt adjustment as well as idle, I think my idle is down closer to 1100? No it didn't always do it.
My carbs have never been off or cleaned, I always use Stabil in my last tank of the year. I did this in my kids 370 as well and had to replace the carb this year, so I may need to clean them. Mine is an 04 Warrior I ordered early so I think it's most likely an early 04 I picked it up late September of 03.

What are you gonna do for a belt adjustment?

Check page 8-16 in your manual, you add or remove spacers on the back side of the secondary, looks like I need to add spacers so the studs don't go in as far, the sheaves will stay closer together moving to belt closer to the top of the clutch.
