This post isn’t terribly interesting – it’s a place to put photos of the damage to my Husqvarna TC449′s muffler. I’m posting this for the benefit of Bret at piperepair.com so he can tell me if this damage is repairable.
Here’s an overall view of the muffler:
Here are two views of the two major creases in the pipe, right at the point where the muffler mounts to the frame:
Here’s a view of the bent mounting bracket. The mounting surface should be flat, and the bracket should have two clean angles in it. Instead, it is now curved.
So what do you think, Bret? Can you fix it? Should I box it up?
I finally personalized my new Husqvarna TC 449 with some Decal Works custom backgrounds. I really like the way it turned out. Decal Works’ pre sales service was fantastic. They emailed me some images of what the bike would look like with various options. The stickers themselves were great, and fit perfectly, a nice achievement given that many of them wrapped over corners, or went on creased surfaces.
I chose one of their simpler options, the “Super” series graphics to show off the radical lines of the big Husky. I also went with a Italian “tricolore” scheme, which I have always liked on Italian exotic motorcycles. I was worried that it would come out looking like a pizza delivery scooter, but I think the green is subtle enough to not be too silly.
Buddies Walter and Doug and I took our play bikes to Saint Joe State Park. The weather forecast was dismal, but wrong. While the ground was wet, we didn’t get a single drop of rain, and we enjoyed a high of 55 degrees, making for a great day of riding.
I had a funny thing happen. In our second hour of riding, I found that my bike was acting funny – hesitating at more than half throttle at high rpms. Out of gas? Bad gas? I topped off the tank. No real improvement. Over time, it got a bit better, but not much. I had visions of piston ring replacement, or hunting down a intake leak. What could it be?
The post ride bike wash revealed a blocked spark arrestor – more than 70% was caked in mud. No wonder it didn’t run right!
Brother John and I trailered the MX bikes to Lincoln Trail Motorsports in Casey IL on Sunday. The weather was to be great, and track prep was promised. I got up early to load the car and trailer. It’s a long drive for us – a little over two hours.
I worried out loud, about 30 minutes from our destination that I grabbed a helmet when I was packing that I thought was mine, but I didn’t check it; I realized that Helen’s helmet is stored in an identical bag. “Wouldn’t that be awful if I brought Helen’s helmet instead of mine?” I said.
After paying gate fees at Lincoln Trail, we unpacked and quickly found my fear to be true! No helmet for me! Auuuughh! I was so angry at myself. My brother consoled me. We would take turns riding, and I could use his helmet and goggles. It wasn’t ideal, but it was at least a way for both of us to enjoy the day to some degree.
So we took turns. And we had a great time. I enjoyed watching John ride, and he was happy to watch me. Neither of us has any real endurance for motocross, so our riding time wasn’t diminished much.
Then the second bad thing happened.
The newly rebuilt motor on the YZ gave out.
I distinctly recall being alarmed at the sound the Yamaha was making as John went by on his last lap. It was wheezy, with a kind of dull clatter instead of the deep thump of a healthy MX motor. “Ugh” I thought. And as he came by, right in front of me, over a low tabletop jump, the motor seized in mid air. John saved it somehow, landing with the rear wheel locked, he was up over the bars, feet off the pegs, but he didn’t crash. Thank God, I thought. What a total disaster this day had become.
I probably messed up the wristpin clips or something during the piston installation. Only a teardown will reveal it. No sense speculating. The next step is to pull it all apart.
On the way home, I tried hard not to be morose. We had actually had a very good day. Lincoln Trail is an excellent facility. I wish I lived closer. If it was half an hour away, I’d be there twice a week, I’m pretty sure. The Husky was fabulous, easy to ride, confidence inspiring, and fun. John enjoyed his first taste of motocross immensely. It’s all overwhelmingly positive stuff.
Now if I could just remember my helmet, and not botch my bike builds, we’d be sitting pretty…
Sixty four degrees in the first week of January. Saddle up the Z1000 and feel the warmth of the sun while you can!
It’s New Year’s Day! Time to ride!
In our family, we try our hardest to get at least a short ride in on New Year’s Day. Today, it was easy – temps in the mid 40′s, only spoiled by wind over 20 mph. Helen, and Henry, and I started off the celebrations by riding around the back yard on our off-road equipment – I on my TT-R 230, Helen on her TT-R 50e, and Henry on his Kawasaki branded Fisher Price PowerWheels KFX quad.
After a half hour of circulating the back yard, we all had lunch. Then Helen and I rode the Kawasaki Z1000 over to her cousins’ house to wish them happy new year. Road speeds and the wind proved more uncomfortable than our suburban trail ride in the back yard. But that’s all part of the New Year’s tradition – ride the ride, even if it’s a little uncomfortable.
I ordered a remote preload adjuster for the shock on my Husqvarna TC 449 from the Husqvarna performance parts catalog. It arrived yesterday. What a pretty piece of equipment it is!
The point of the adjuster is to replace the lock rings that come on the shock so one could adjust the rear sag of the bike with a 8mm t-handle wrench after only removing the seat. The rings that come stock on the shock are only accessible after the right side plastics are removed, and then to adjust the sag, one must use a drift, as there still isn’t enough clearance to use a shock spanner.
Shock removal went exactly as the Husqvarna service manual said it would, pretty simple. Removing the spring was harder than I expected. The shock body isn’t long enough to allow the clevis to be removed even with the lock rings moved all the way up the threads – I had to use a spring compressor to get the requisite clearance.
The adjuster threaded on easily, and adjustment pin loosened up nicely just from the installation.
Putting the shock back on the bike was a chore – the adjuster fits nicely in the space provided, but doesn’t allow enough clearance to the gas tank to fit the top eye of the shock into its space on the frame. I had to loosen up the muffler clamp and the bottom bolts of the subframe, and then remove the top subframe bolts completely so I could tip the gas tank back far enough to install the shock. That worked, and isn’t too much of a hassle for future servicing.
The adjustment collar fits nicely and works very well. It should make trackside sag adjustments a snap.
