If new, relatively inexpensive coils are preferred, the linked items from Z1E might serve the purpose, but before ordering would contact Z1E to inquire specifically about application to the bike at hand.

It is an oil seal, not a bearing, which leaks. #9 is the one for the shifter shaft. I would replace all of the seals there on the transmission cover.

it started to leak because i didnt want to take off the foot peg to get the chain cover off so i should only need the one.

over the weekend i got the oil drained the dyna coils installed. pulled the chain sprocket off and need to replace it along with the chain and rear wheel sprocket any input on the different tooth ratios would help not sure which ones to get

If you are not sure, always go with stock. I'm not sure what stock is for your bike, but if you want to play with the numbers, there is a gearing program for 550's in my signature.

You may have to download it to your computer since some browsers won't let it work.

Normally, people don't go bigger on both sprockets (or smaller on both). That reduces the difference. Usually you would just change one or the other, or go opposite directions on both if you want a huge change.

Be aware, you will likely have to get a non-standard chain length if you change both in the same direction. Sometimes you have to change the chain even when only changing one sprocket size.

If you want more torque, wheelie ability, you go down one/two teeth in front, up two/four in back. If you want more top speed, you go up in front, down in back. Changing both up or both down does nothing at all, or so small difference it doesn't matter.

so i ordered a f 18/r 38 sprokets and a 150 link 530 chain so i can pop out the links i dont need

i was thinking of using a 20w- 50 oil. as to how hot it gets down here



but i will also be puting this project on the back burner if i dont get it running by july because a great deal on a sportster 1200 just fell into my lap all i have to do is fly to nj to get it and then ride it down the coast 1000 miles and $90 in gas. i will have me a bike to ride while i fix my kz up :woohoo:
