What is 08 Busa full extension of front fork?

[TulBusa]

I want to set my sag, and don't have a way of extending the forks fully out to get the measurement for full extension. I'm sure someone has done this and it would greatly help all 08 Busa faithful.

Setting your sag takes three guys. Have your two buddies pick the front of the bike up off the ground by use of the clipons so you can measure your fully extended forks. Measure from the seal lip to the bottom of the tube is the best measurement.

Have one friend balance the bike from the rear while you are sitting on the bike in your riding position, preferably with your riding gear on. Now have another friend gently push down on the front enough to compress the fork springs a few mm and then gently let the springs settle. Take this measurement.

Then do the same thing except this time lift on the front of the bike and let it settle into place. Take this measurement. Take the average measurement between the two and this is your "Rider Sag". This allows for "Stiction" which is the amount of drag created inside the forks. Adjust accordingly.

You should also take the same measurements without you on the bike to get your "Free Sag" numbers which will help you to determine if your spring rate is proper.

Have you decided on what sag numbers you need to reach your goal?

Be sure to set the rear up with the same sag numbers you aquire on the front.

tuf, thanks for the advice, but I have a chock and rear stand which will eliminate the need for other people.

Surely somebody knows the measurement of fully extended 08 Busa forks, that's all the info I need. Anyone?

No sir, that won't work using stands. Your bike must be sitting flat on the garage floor to make proper adjustments.

Find two friends and do it right the first time.

tuf, do you know what the measurement is on the 08 Busa for fully extended forks?

The distance between the lip of the dust seal (the point where the dust seal touches the inner tube) to the bottom of the inner tube (the point where the inner tube fits into the foot) is 116mm. The actual useable fork travel is less by 10mm. or so.

Use this measurement to set your sag. You are looking for about 1/3 of your travel to be used for rider sag. I shoot for 35mm of sag for the busa.

However, as I said, if you set your sag with the bike on stands, it will not be accurate when you take it off the stands.

Before you start, crank the compression all the way in and count the number of turns. Write this down for future reference in case you want to go back to stock. I'd suggest you do the same with Compression and rebound. Count the number of clicks to the stop and write this down as well. If you get your suspension all whacked out you can always go back to the stock positions and start over.

Your compression and rebound settings are the major components that change the way your bike handles. If your suspension is not bottoming or topping out, you won't notice any difference in the ride after setting your sag. Be sure to set the sag at the rear as well.

110mm usable is dead on.

1/3 is a good target static setting, but the most accurate way is to set 1/2 with you on the Busa with all your riding gear on. You will need help to do it correctly. The bike will handle much nicer if it's set correctly.

Great information Tuf, thanks for the posts.
