Maintenance madness

The old SV was in need of a few things, some simple, some not so simple, but added together amounted to a lot of work. And, hopefully, a better running bike.

First was a new front tire. It was really eye opening to compare the new tire to the old. Yikes.

Next was an oil change. No biggie.

Then it was time to flush the brakes F&R. Not difficult.

The coolant was 3 years old, so out with the old, in with the new! Flushed the system before putting in new coolant. Messy, but not terribly difficult.

When out on the test ride to confirm that the cooling system was working as it should, I noticed some difficulty in staying on-line through certain corners on Canyon road. In a temporary moment of lucidity, it occurred to me that, with 53K miles on the bike, the steering bearings were probably shot. Putting the bike on the rear stand and putting a jack under the engine, the front end was off the ground, confirming that, yes, the steering bearings were toast. Move the bars: CLICK to the next position, CLICK to the next position.... no wonder things felt "off".

A few days later I picked up an All Balls bearing set at Fun Country. Stock bearings are ball bearings, the All Balls kit is tapered rollers. I had to figure out a way to get the front end off the ground without using a triple tree stand. Got that figured out and the bike was solidly supported and ready for... a "shipload" of work!!!

I'll spare you all the tedious details of replacing the bearings (slightly complicated by using different bearing types). Of particular difficulty was getting the old races out of the frame. The top one required using a very long drift and hammering it out, while lying on your back, with arms fully extended. Only problem, you can't see which side needs to be hit to avoid cocking the race one way or the other... after about 40 minutes of calisthenics (hammer, stand up, check progress, lay down, hammer, stand up check progress) I finally got some help, telling me which side to hammer, and got it out.

One thing that needed to be done, since the bike was way disassembled was to paint the lower triple clamp that had lots of rust from the generous use of salt on SR142 and my high mileage winter use of the bike. Got that done first thing after NAPA removed the old lower race from the stem. Had to go back to get the lower bearing/seal pressed on. Joe, in The Dalles did a great job and didn't even screw it up!

Reassembly was amazingly quick. The new races went into the frame straight and easily. The rest of the job was not too bad. But... since the forks were off, by golly, let's change the fork oil! Really messy, but nice to get done. Amazing, that with only 5K miles on the old oil, that tiny sparkly particles would show up in the drain pan.

So the SV is so up to date on maintenance it's scary. Tomorrow I'll test ride it to make sure that the front end work was (miraculously) done right. Can't wait to feel the non-indexed steering; should make for a lot smoother line through certain corners.

I'm really glad that all of that stuff is done!

I'm finding out that steering bearings require quite a bit of preload, especially tapered roller bearings. I took the bike out for a test ride this morning and, at low speed, it felt more loose than it should. It would react to pavement angles and tar strips, making it go left or right when going straight. I did a few searches and found that this is a symptom of too little preload.

So, I got the front end off the ground (to get a feel for resistance to steering effort) and cranked in about 1/8 turn on the adjuster. I really need a socket to use with a torque wrench to measure the torque value on the adjuster. If this adjustment doesn't fix the issue, I'll buy the socket. $35 on ebay...

The bike works a lot better cornering, nice smooth arcs without the notchy response caused by the worn out bearings.

By the way, I'm over 60 and all this stuff seems like real work, to me!

I know man...I have 2 sets of all balls to go into my 99TW and 78 GS-550E. The 05 ZX-10 could probably use a set as well since it has 40K on it and feels a tiny bit clicky...though I lube them up well every couple of years. Thanks for getting the anticipation up!

Got sockets and torque wrenches

..
If you want to borrow...just down near canyon Rd....a lotta big sockets here... probably a 27 mm? Got that. Come by and we'll torque you up... I also have a come a long suspended in my shop that I hang the bikes from to work on the forks, etc.
You think your DVD is work....try a clutch job on a Ford 4x4 truck.... I just finished one of those.... Oh

Hey gnarly, the socket I need is one of those slotted ones, similar to the ones used on some swingarm pivot nuts. Here's one on ebay so you can get a look. I've got some muncher big sockets, at least in metric sizes. I've got 5 (yes, 5) torque wrenches in various ranges. Thanks for the offer! Clutch on a 4x4? That's real work!

I got some good input from some guys at SV Rider forum and got the bearings set correctly on my bike. It was tedious, but the test ride went very well; it's almost like a new motorcycle, no kidding.

Details at SV Rider, for those interested.

Edited to add: the solution was less preload, not more.
