Hi all,

Gonna change my fork oil and bleed my brakes this week. My front end feels a little soft and I am thinking of running thicker fork oil. Is this a good idea? Also what fork oil and brake fluid is everybody using?

Thanks

Mike

The screaming eagle fork oil seems to work just fine, its a little heavier than stock. As far as brake fluid goes use any old dot 4. I believe thats what the Buells use. Harleys use dot 5 & that stuff wont hurt paint.

Does the M2 have drain screws on the fork legs? If not it will turn into a major pain in the ass job.

My '99 M2 uses dot5 brake fluid and my '00 blast uses dot 4. No drain holes on bottoms of forks. They must be removed from the triple trees. The service manual explains all the steps for this procedure. Note: The amount of oil you put back in the forks also changes the action of the suspension.

Pre 2000 Buells use DOT 5; later Buells use DOT 4.

You can pump the oil from the forks to avoid disassembly.

Try adjusting damping settings before changing viscosity.

I wish my Dyna used 3 or 4, lot easier to find & cheaper too.

Mike,
I have a 2K M2 like yours.
I just did the fork oil, seal replacement and spring replacement thing.
I push 230 fully dressed to ride, I needed a bit more dampening as the stock was a bit mushy.
When the dampening was cranked up it got a bit harsh.
I put in 1k springs and 7w Belray fork oil.
Seems to work pretty good for me. I did over 500 miles this past Sunday, most on the freeway, but in the corners it did feel more "planted" than before.

In order to remove the top fork caps, you either have to pull the bars or drop the fork leg out of the triple clamps.
I found it easier to pull the legs.

Depending on how many miles you have on the bike, you may want to flush the forks before refilling them. I was suprised how contaminated the oil got in 5000 miles (last time I did a seal due to a rock ding).

Before you "pump" out the old oil, back off the dampning screw all the way. The oil comes out easier.

If you don't have the service manual, GET IT!
It tell you everything you need to know for this job.

Brad
