Great video. The steering stem play check, grabbing the forks from the front, is also a good way to check your forks for bushing wear. Thank you , Flat Track Factory.
Sticktion. Stiction. Stickshun. Stickcion. My new favorite word. Seriously, though, I’d totally watch a video on each of those. And I’d love to see that “super cool tool” in action...I’ll have to watch that part again to follow how exactly that measurement is facilitated.
Another way to check/measure axle swing arm is true with axle is to measure inside nut to outside nut on the flats to give centres. Not as good as cool tool but better than trying to guess centres
Hey bro, I love your advice, I'm old a65 model, I used to race speedway in the 80s , I am trying to prepare a2010, triumph scrambler for a sandy half mile, trotting track in Ouyen, Australia,in March 2023, any advice would be appreciated 👍
Congratulations! Keep us updated on the build. Check the rules first. Buy the best protective gear you can afford. Watch my back catalog of vids. There's some good stuff in there, I hope. Feel free to ask specific questions after that.
It's made from chromoly steel by J&M Racing Frames for my chassis. I really like center flat track style stands because you can balance the bike so either end will be unweighted, depending of what you're working on. What else would you like to know?
@@FlatTrackFactory thanks for the reply! One more thing. Is this center stand fixed to the frame? It's just so rare to see a center stand on a race bike...
I see the confusion! It is NOT connected to the bike. It's nothing like a center stand on a normal m/c. In fact, I forgot that the term "center stand" probably means the thing under a scooter to most people. Sorry about that. It's a lever type of device that lifts the bike. You can sort of see it in some of the channel's other videos in some shots.
For me, on my current framer, I am at 7.8 degrees. I slowly worked up to this from quite a bit flatter. This might be a good thing to cover in a new video. Thanks for the question!
This might be a frustrating answer, but it depends. What I have done in the past is start with spring rates recommended by J&M Racing Frames and Durelle Racing. Then set rider sag in the area of 20-25mm. For me however, spring preloads are the most adjusted setting on my motorcycle. If a track is banked and tacky, the bike will show excessive suspension travel with higher rider sag settings. In that case we'd increase spring preloads to maintain geometry under the increased cornering loads. If we take those settings to a flat, slippery track the suspension will not transfer weight much at all. Then preloads would have to be lower (creating higher rider sag numbers). I have a suspension professional revamping both ends of the bike right now and plan to make a video about it in the future. Hope that long winded answer helped. Thanks for checking out the videos!
Assuming the spring rates are correct, I think 25-30mm of riders sag is a good starting point. 20 can work in some circumstances for some people, but can make the bike seem twitchy. Consider reaching out to someone like Durelle Racing. Davey has vast experience and can quickly help get you on the right track

Really enjoy the tech stuff. Would like to see more on suspension set up. Forks and shocks!
I'll see what kind of racing-nerd stuff I can come up with. Thanks for watching!
Nice tips on setup ! On the axle to swingarm measurement I like squaring-up the axle nut so I can hook my tape measure to get real accurate!👍😎
Great video. Keep them coming!

Good tip! Thanks for sharing.
@@FlatTrackFactory pleasure, my dad showed me that one 👍

Thank you for replying, you're a legend 👍 there's more to a hooligan build than just pulling the lights and blinkers off 🤣
Tell me more about that centre stand you use on your framer!

@@FlatTrackFactory now I get it! It's more like a paddock stand as we say on road racing. The trick on this one is balance, like you said 👍
What pipe do you have on the Tax, looks well made. Is there a packable muffler in it? Looking for a pipe for a 82 Honda 500 single.
It's a one-off build in all stainless by the engine builder Gerry Wilhelmy at General Engineering. No packing at all,
Hey Mike! What are the benefits of a clean chain?
Makes you look pretty and intimidates your competitors...and makes the chain last longer. :)
What are you looking for as far as swingarm angle?
For me, on my current framer, I am at 7.8 degrees. I slowly worked up to this from quite a bit flatter. This might be a good thing to cover in a new video. Thanks for the question!
Amazing chassis. The brand is?
It’s a J&M by Mike Owen of J&M Rracing chassis in Poolesville Maryland.
What's the bar for on circle dirt track bikes? Hangs off rear wheel.
Edit: Guessing anti wheelie bar?
Speedway bikes have a roost guard to keep from blasting the guys behind. Is that what you are asking about?
@@FlatTrackFactory
I think so, not sure. It probably is exactly what you are explaining. Thanks for the reply 👍
not binding up the forks when tightening an axle....follow the correct sequence
Craig Powell For sure! Great point. Thanks.
Hey what sag numbers do you run?

@@FlatTrackFactorythanks for the fast reply. So 20-25mm is a good place to start for both front and rear?
