Can you do a top speed on the dirt bike?

[@MartinRacingChannel]

I'm putting a brand new stock 125cc from X-PRO now once I get it installed and broken in. I'll do a top speed video. Do you have a certain speed app you use or will any be fine?

[@Elai-gp9gp]

Hey i have thr same bike and want a new carburetor but dont know which one or how yo find one. Can you help?

Here is a video of what I run. There are links to buy the carb and air filter as well.
This is my bike and the whole install/ tuning.

[@stephenlarkowski8186]

That’s upsetting.. when you put your upgraded shock on your bike after you blew out the stock shock, how did the swing arm sit to tighten the chain? I did that upgrade to my son’s bike (same as yours) after I blew his shock out also haha. But when I sit on the bike now the chain tightens up and I don’t get it. I’ll set the chain loose then sit on it and boom it’s tight! What did your situation do?

[@MartinRacingChannel]

If you have someone that is your weight or pretty close, have them sit on the bike and adjust your chain to where you have about 8mm to 10mm of slack on the bottom half way between the sprockets.

[@MartinRacingChannel]

You might have to fine a middle point since you are setting it up for your kid, too. You don't want it to be too loose while he is riding, then too tight when you are. You'll get it dialed in. Make sure you torque the axle bolt to 85ft lbs. after you adjust the chain or the chain will loosen up when hitting jumps.
Definitely not what I wanted to happen with the engine, but I have it back up and running again.😏

[@Kroviakjm]

Dam that sucks

[@MartinRacingChannel]

Yes, it did. I got the bike up and running again, though, and Tbparts came through and sent me a fresh topend. 😁

[@MrAdrianjohnson]

I wanna see that video

[@MartinRacingChannel]

@MrAdrianjohnson Metal was all in the bottom end we got it cleaned out , bolted the factory topend on and it was good to go. I put another 10 or more hours on it before putting the new topend on.
I'm working on the video where we got it cleaned out and running again now.

[@MrAdrianjohnson]

@@MartinRacingChannel cool I have a xpro storm 150 dlx so your videos come in handy. Thanks

[@MartinRacingChannel]

@@MrAdrianjohnson That's awesome! Glad you found the channel. The best mod for the dollar is going to be the nibbi carburetor. My bike became so much quicker for not much money at all. The engine kits produce all kinds of power , but they cost a lot of money too.
