Not enough information to troubleshoot. Re-trace your steps on everything you worked on and double check. Why did you loosen the chain? What were you fixing on the secondary?

ok i was chacking my cam slider shoes and i noticed the secondary and the hole shaft was moveing back and forth a qurter inch so i pulled the top sprocet off.i could not fined anything wrong so i took the brake off and still nothing wrong and i wonted some more room so i loosend the bolts on the chain case then i relized it was a full case and i would have to take the hole thing out so i tightend the bolts agine.then i took the secondary apart then i founed the bolt that holds the secondary on to the shaft was not thare wich is funny becuse that was the way it was when i got the sled running four years ago. and i did not now that.so i pull the hole secondary off and i used a hammer but i did not beat the snote out of it but i did use some force.so i put it back together the right way.then it started to viberate in the front.

i slammed my head against a wall hard enough to bring my sanity back and replaced my secondary with my spare and it seems to be fine now but i dont now how long it will last i'll enjoy the bliss while it last.
