WHo sell timing keys for a 2000 ZRT800 (piped, jetted, clutched, reeds) and what degree would I want to get? What are the pro's and con's? About how much money are they? Same questions for reed spacers. Thanks

I believe d&d carry the timing key and I have never heard any bad from them,,,but I asked about reed spacers and was told to save my money,,,, they are no good,,,,I did not get one good comment about them,,,,

What exzctly does the timing key do?

Timing keys, advance the timing 1 or 2 degrees for drag racing... they are very cheap,, but you have to have a puller to get them on ( i think),, same with reed spacers,, fairly cheap, they supposedly fill the cages more, when you pull them out,
