NO SLACK?? Like ...stretched tight? Ideally the the chain should have 0 slack ONLY if the suspension is fully compressed....like if you bottom out the rear shock. If the chain is adjusted properly, it should have a visible droop in it with only the weight of the bike on the suspension. The chain should be touching the plastic chain guide on top of the swing arm when the suspension is only carrying the weight of the bike. There are pics of proper chain slack here.
If you have 0 chain slack, that will stretch your chain out in short order. It will fix itself by stretching your chain. It will cause some wear on your sprockets and obviously shorten the life of your chain. It could cause damage to the output sprocket bearings but probably only if you adjusted the chain this tight repeatedly. Worse case scenario, your chain could snap. That would probably total the bike and get you seriously injured.
This was a dickhead way to adjust a chain for a customer. I would absolutely NOT go back to this shop. You should get your money back if they charged you for that. If there really is 0" chain slack, I would not want to ride the bike until the chain is adjusted properly. If you do need to take it a short distance, go very slow and try hard not to hit any bumps. I would insist on watching the tech adjust the chain. They probably had a 16 year old kid with no experience do this job. No mechanic with minimal experience would adjust a chain like this. It's unsafe for the street and I do not think it is even safe for any kind of racing because there is always going to be some movement in the suspension.
I just called the dealer and he assumed that I did my own adjustment and wanted it that way.
Probably a lie.
I picked my bike up and went the first 500 miles before my first oil change.
I seriously doubt anyone could ride 500 miles on the street with 0 chain slack and the chain did not stretch to proper tension. Anyway, who did the dealer prep? They should not have adjusted the chain this tight in the first place and they should not have allowed it to leave without asking you about the chain slack. This is so basic, they cover the procedure in the owners manual.
This is not hard to do yourself. The first time, you might have to do it and undo it a time or two to get it right. You will probably only need to turn the adjusters in about 1/6 of a turn. ..maybe 1/3 (2 flats). The only risk is tipping the bike over when you loosen the axle nut. If you take your time you can do it. Either that or I would consider going to another shop. Usually, avoid dealership service, they are in the motorcycle sales business not so much service and repair. Get several references.
