i just got a ss rumble pack for my zr 600 for christmas. and something has gone wrong with it about a couple days ago. it seems like power loss and it doesnt sound the way it did about a couple weeks ago. one day i was just riding it and this happened so let me know if you got anything or any suggestions out there for me.

Don't think that is your rumble pack unless something is clogging it.

well you see its never done this when i had my stock can on. would you think it would need to warm up a little? because i let it warm up for about 10 minutes once and it seemed better.

I still don't think its your can. The can is a pretty simple design. Really the only thing that can go wrong with it is get clogged, or get a nasty dent in it and restrict airflow. I'm guessing its a carb sled so you wouldn't need to remap it.

OK that makes more sense now. I will bet you have water turned to ice in your carbs. I had this happen to my dads sled last weekend. I didn't want to run good for the first day about 20 miles. but after I stuck a heater on it over night thawed the ice out and run it through with the gas it ran much better.

Advise: Put it in a heated garage over night, i would also take your air box off and stick a small electric heater pointed at your carbs to melt the ice. then if your air box has ice/water in it clean it out. and run the sled in a heated garage for 10 Min's to send the water through.

forgot to pose that it doesnt start losing power until aroound 40 but still something isnt right. is it possible that it could be the gas filter and the higher the rpm its not getting the gas it needs?

yeah but i dont think that much water got in it i mean the track wasnt really under water, i went through the ice right at the beginning and then got back on the ice so its not like it was all water.

Im not sure how the water got into my dads sled either but it did.

Yes it could be your fuel filter, or it could be your main jet is plugged. I would clean your carbs.

Highly doubt it's your can. Put the stock can back on and see if it does it. Sounds like you have a carb issue.

cleaning carbs might take a half hour. you will just need to take the bottom float bowl off. (4 fillip screws.) and then you will just need to take some carb cleaner and clean it out. spray into all the holes and make sure the exit some where. take the main jet out and make sure that is clean. there is a diagram on how to clean carbs on this site somewhere But im not sure. someone should chime in and show you.

It will take about 15 minutes per carb maybe, and you just take it apart remembering where everything goes then spray some carb cleaner and whipe it down. You can fit a small needle into the jets to clean them.

these are flatside carbs, Im not sure if you have flatside or round, but you wont need to take the slides apart. the bowls are relatively close for both types.

you probably already looked at it, but there may be a chance you didn't have a proper seal of high temp. caulking which would allow for an extreme loss of back pressure. just an idea
