Your rpm should be right around 8750 when climbing . With those weights they are a big more aggressive then the factory ones .
The sled comes on a lot harder almost feels like you’ve added boost.
Will also drop your engagement from 4100 to 3100 .
I found it made a huge improvement for me !
Part number for the weights is
#8LR-17605-00
And the rivets you need are
#90261-06033 steel 4.5g.
You’ll need 3 per weight. Once you put them in the weight should be 73g
Have a read on this thread. Great info about clutching . Personally I did change the weights to Heavier ones . 73g each loaded. I can get you the part numbers if you’d like .
Also with those weights I changed the secondary spring setting to 3-3 60 degrees

The Cr straight pipe gives 20hp and 10ft/lbs
Torque
The Cr intake drops 1lb off the sled and just lets it breathe easier. Stock intake prone to blocking up with snow.
You’ll have to come out on a trip with me and stuckey this season and we can put the two sleds side by side[emoji1687]
Lol I told dean to tell you what kinda hp you have. But go to Cr racing’s website. Assuming it’s a Cr racing exhaust. They have a resonator or a straight pipe . Which one do you have.
They are having a horrible time dealing with mirage for trailers and I ordered some trailer parts back in December that they still haven’t received yet! I heard they are going to stop selling their stuff soon!
Yes I am running stock gearing!!
Only been out twice with those weights. And both times was hard to keep watching gauges cause the snow was so deep!
But I’m chappel creek I’m valemount on the hill off the main lake . I was pulling 60-63 mph on a fresh line. And 8600-8750 rpm never went over...
This is the Yamaha part number for the weights
They come without rivets
You’ll need 3 weights obviously
#8LR-17605-00-00
Here is the part number for the rivets which you will need 9 of
#90261-06033 they are steel 4.5g
Yes they are a Yamaha part. They are actually the weights from the BTX sidewinder I believe. I’ll get you the exact part numbers tonight. And yes as for secondary I think 3-1 is stock setting switch that to 3-3 the twist 60 degrees into pace to bolt back up.
