Read the owner's manual. It tells you exactly how to measure and set the chain tension and many other essentials. You want ~2" of total movement for the FZ6. It's based on swing-arm movement. If it's too tight, you get noise, premature wear and shifting issues or worse.
From the manual...
+1 buy the tools and do it yourself. Your tools will pay for themselves and you'll gain mechanical experience to help you tackle more work on the bike down the road.
Have an experienced mate w/ you if you can. Well worth a 6 pack. A helper can also hold the rear brake for the front nut removal...
99% you simply need a new battery- its ability to deliver current is mostly likely shot. That's why you get clicking instead of the whine from the fuel pump priming.
The battery should read about 12.6V or higher fully charged. You can monitor the voltage at the terminals as you key on and the...
Here's a shot from my first proper touring ride of the season, 230 miles round-trip on the Fizzer.
This is the Columbia River Gorge, shot from the Maryhill Stonehenge WWI memorial site overlooking the vineyards of Maryhill, WA.
Oregon is in the background across the river with Biggs...
Voltage is only part of the equation. If there's an electrical fault, the bike can pull more current from a running car than its wiring can handle and worst case goes up in flames. Well worth a caution!
Anyways, glad you're up and running!
1. Don't rely on the measured amount of oil you put in. Put the bike on the center stand and check the dip stick. You want the oil to be at or close to max. Much less you can get a low oil light. Not sure if the bike would electronically refuse to start with less.
2. Monitor the voltage at the...
I had already completed the spark plug procedure but have been getting some vibrations recently that make my feet numb from the buzz. RPMs around 6K were the worst.
What has really seemed to help is re-torquing the engine mount bolts and nuts. I loosened in reverse engine install procedure and...
If the chain is really driving you nuts, you can put the bike on the center stand and run the bike through the gears carefully. A 2nd person could watch the chain or you could record video. Keep all fingers well away from the chain. Be safe.
I wouldn't consider the problem isolated yet, but yes, that's the correct kit part #. Any Yamaha dealership should be able to order it for you. I'd price up the chain and sprockets separately elsewhere for comparison.
Can you see a brand or size refenced on the chain? (e.g. DID or 520/525/530)...
I wouldn't replace anything at this point. If the chain wasn't changed with sprockets as a set, then I would expect some noise and accelerated chain wear. Just keep the chain lubed and recheck the tension more regularly.
If the chain "stretches" at an alarming rate then I would recommend an OEM...
