I picked up a new project for when the ATK gets finished up. This wasn't really on my radar, but it was fairly local to me and I had never actually seen one. I thought if I didn't pick this up, I would probably never have the opportunity again (unless

Got caught in a lull. Finally found time to pull the forks and tear em down. I had no clue how these came apart but there are no compression or rebound adjustments in these simple WP 4054 old school 40mm inverted forks so they werent too hard to navigate

Good point

I bought this bike new in fall of 2010. It rips. All I have ever done engine-wise has been to change filters somewhat regularly, clean the carb often, and change the oil occasionally with cheap 10w30 dinosaur oil. I also started using a BR8EIX plug for ... more »

Bringing this back from the dead. I have also been using ERT2 chains and recently ERT3. I agree with langhammx....this thing stretches way too much and the gold looks like poo in no time. Im done, but not sure what to switch to. I love the low drag of ... more »

Shifter done. Welds look ok, but both the old shifter and the wrench were chrome plated and as usual I couldn't be bothered to really clean the metal up. The fit is really good. And while it looks long, remember that the old shifter was pretty stubby.

I messed with the shifter. Here is how it was before I touched it. A prior owner tack welded the pivot into a fixed position and did the grinding on the weld. I was able to remove the weld and clean it up to make a functional pivot again.

Thanks to Husabutt on YouTube for pointing out that one of my rear frame rails appeared to be bent. After some measuring I comfirmed that he was right. The silencer side was 1/2 inch higher, which is why my fender was twisted after I mounted it. I should

Thanks Matt...there were a couple good shots in there. My clutch cable I decided to leave alone. It has one lone broken strand up by the perch. Certainly I can use it for now and just keep an eye on it. The throttle cable was fubar though and already ... more »

Well its been almost a year and Ive got 7.6 hours just playing in the yard. The clutch still felt like poo...you either set it to disengage in neutral and feel it slip on the top end, or you set it to not slip on top and never be able to find neutral.

Thanks...that helps me visualize it. This airbox has plenty of room to breath around the inlet and outlet so I cant imagine it would generate that much vacuum, but I had never really thought about that.

Thanks Chuckie. This bike was fairly complete, however it was missing a mudflap. I don't even have great pictures of one, but sort of figured out what it should look like and I know it should be white. I mocked up a template with an old cereal box and

Added reply in a thread how to pain a motocross frame 4/25/2020 8:02 AM

Pics of the frame would help. If its already a painted steel frame, new paint will adhere to the old pretty good. No sense in peeling that away. Just use a steel brush and some solvents to flake away the loose stuff. If you have an abrupt transition ... more »

Im also blown away at the quality of these "straight from China" riser adapters. Ive been using Rox Risers on several bikes now, but those are $85 and rarely go under $80. I was going to try a Zeta brand for $45, but these were $26 shipped. They are

Had to install the forks in order to address the brake line, which was twisted up pretty bad. The shielding was also damaged just below the guide that mounts to the steering stem. That stuff is brittle like glass so I used a pipe cutter to cut about

I havent torn into the carb yet, but the outside is clean so I mocked up the airbox to see how it was all fitting. The airbox side has a 2.75 inch outlet and the carb has a 2.5 inch inlet. The prior owner had a conglomeration of zippy ties and a janky
