Thanks Srxspec,

Thanks Srxspec, I think I have a yellow purple yellow I will recheck my photos and post tomarrow sled has not run the same since first oil change was done. No belt ware on top 3/4'' of primary

is there any clutch spacers on (3 bolts on back) a stock 06' ER or does it come w/out any. just wondering how many you can put on as mine already has 1 shim.

shims

you only need to add if your belt is to low in secondary, if you add 1 washer
it should be enough.

Sorry this took so long but I finally got photos of my clutches. Could someone take a look and let me know what you think. It looks like the belt dose not climb high enough on the primary clutch and sets too low on the secondary. I weigh about 290 with gear. and would like to tap into this lost performance. Sled has about 1500 miles on it top speed has ben about 113 (Speedo)on forest road never had a chance to run it on a lake that was plowed or had a well astablished trail. At this time i dont have rpm data but could have that later. Please let me know what you think Thanks

Looks normal to me!!

Looks like your belt is slipping and not shifting out fully. I would try a spring with same engagment but lower full shift before you starting adding weight. Also, clean your clutch with some acetone and light scotch brite pad to remove the rubber off your sheaves.

Thanks for the input! This is my first Yamaha and Im still sorting things out.

The blackening of your sheaves is typical of the stock clutching, IMO.

My Dalton setup is clean.

Ive considered a clutch kit but with so many choices its hard to sort out

Make sure you add the 23 top gear as well. If was me Send your Primary clutch to Allen and have it machined.
