Can I use an impact? Or do I need to do something like this?

1/4" x 1-1/2" x 4-3/8" Aluminum flat bar with the ends rounded to fit the tooth profile is what I use.

Using an impact may damage the magnets in the rotor.

Have the FACTORY SPROCKET LOCK TOOL, "BUT" it show's you know how to improvise and think out of the box ...

"i" prefer a long breaker bar than an impact wrench as "i" like to feel the movement ...

long breaker bar! the clutch hub nut is l/h threads and a lot less torque if you are taking that off too.

The Chain, Sprocket and Basket will come off as a unit after you remove both clutch and motor nuts. As stated DON'T USE IMPACT wrench.

You will need to remove the clutch basket to be able to pull the chain/primary sprocket. The Primary will have a magnetic resistance when you to to remove it that makes you wonder if you forgot something. When you go to reassemble it may be tough to get everything to line up and slide on. Make sure your fingers don't get behind the clutch basket. Those teeth can do some damage!!!

cool, ill get up on the online service manual and check out what i need to do to get the clutch basket off. i was contemplating taking it out to check the clutch plates. guess ill get to do that now.

anything else i should do while im in there?

also, the chain slider... it doesnt seem to have a lot of wear, should i replace it anyways? is that something i need to get from the dealer?

im installing another used chain, it just has significantly less miles than mine does tho

you will want to break the clutch hub nut before you pull the clutch plates. probably a good idea to buy the detent spring clip and replace it. also replace the clutch grenade plate with extra friction and metal plates.

You should definitely replace the tensioner if it is the old thin type. If the steel bar that hold the shoe is not about 3/16th - 1/4 inch thick, you have the old style, and should replace it before it breaks in half. They're about $15.

Look through the manual from start to finish before you dig in. There are a couple of "replace with new..." lines that I didn't see until I was deep into reassembly late at night.

That's a piece of 1/8" thick, 2" wide aluminum flat stock I bought from Lowes and cut down to 4" with a sawzall. I removed the nuts with a breaker bar and a cheater pipe.

Once you get the clutch basket off, you'll want to replace this:



That's the clip that holds the detent plate onto the end of the shift drum. My detent plate was chewed up, so I replaced that too.



Old vs new detent plates:



It's good insurance for $4 worth of parts.

Was the detent plate clip broken before you removed it or did it break upon removal?

I made my lock bar out of an Ace hardware electric edger blade cut down to 4 1/8" if I remember the length correct. The edger blade is a replacement for a Black & Decker edger. I cut the old one down and put the new one on my edger. I worked great as a lock bar.

The tensioner doesn't need replacement unless it is deeply grooved. Like it's been mentioned, definitely update if it's the wimpy one.

It was broken before I removed it. That's actually the reason I took the clutch basket off in the first place.

Don't forget Shifter shaft seal. I'm sure someone has the part # you need. And while your in there check for chafing on the stator wires under the little plate that holds them to the case. I know, it never seems to end.

My local dealer has not been plesant to deal with in terms of anything buell related since the company was shut down. I'd rather get my parts online or somewhere else.

Yes I'll need the pn for the shifter seal, sooner the better I'd like to get them all ordered and shipped out today
