Im changing my front sprocket on my 82 kz 1000 and im not sure if the theads are reversed or not can anyone help me thanks Mark

Having trouble getting it off?

Standard right hand metric threads, turn counterclockwise to loosen, but an impact wrench makes it easier

Thanks steell I finally figured it out. Socket wrench and a pipe works great but an impact wrench would be a ton better. My sprockets are shot so I'm considering the 530 conversion but I'm not sure how long of a chain to get. 15 tooth front and 41 rear (630) is what I have now. Do you think a 14 tooth front, 38 rear and 108 link (530) would be close to what I have? The only reason I'm using the 38 rear is cause I already have a new one in my garage.Thanks Mark

Find below some info I found very helpfull. It is from Z1 Enterprises website. Check them out for your parts.

Final drive ratio.
Divide the rear sprocket tooth count by the front tooth count and you have the final drive ratio.  For example: 35 / 15 = 2.33:1

If you want to change your gearing, you can calculate the impact of the change before you purchase the new sprockets. 

For example; your bike cruises at 60 mph / 4,000 rpm and has a final drive ratio of 2.33:1 - if you want more acceleration, putting a 37 tooth sprocket on the back and leaving 15 on the front changes the ratio to 2.47:1 (37 / 15 = 2.47:1).  Divide your cruising RPM by 2.33 and multiply by 2.47.  Using the example from above, 4,000 rpm becomes 4,240 rpm at 60

630 chain is 3/4" pitch (or think of it as 6/8"), 530 chain is 5/8" pitch - so the simple conversion in teeth is divide the 630 sprocket teeth count by 5 and multiply by 6.

630 15 tooth front becomes a 530 18 tooth sprocket.
630 35 tooth rear becomes a 530 42 tooth sprocket.
92 link rear chain becomes 110.4 links (rounded to 110).

The sprockets are the same diameter as before, just with more (but smaller) teeth.

Often you end up with fractions of teeth - these you have to round up or down - the key here is to calculate a ratio close to the ratio you require...

I just bought an impact wrench at the local Lowes. Came with some sockets, the largest being a 1-1/16" which is equal to 27mm. Took the sprocket off in seconds. it was worth the $95.00
