Thanks for giving the old guy about 8 good laughs Kelley! Your a hell of a 2 stroke impersonator! I'd love to hear your chainsaw cutting Minnesota trees lol. This is a great video about jetting. Even as long as I've been messing with these bikes I never quite understood the needle and clip positions very well. Do you have a video about that? If not I'd like to get a crash course on needle and clip positions. Thanks my friend. Keep the good stuff coming. I promise to get chip in on more videos when I get these medical bills to stop smothering me every week. Thanks buddy 😊
Haha, thanks. People seemed to like it in one of my other videos :D I don't have a video on the needle and clip yet, but I do have an article on my website that should explain it well enough: motocrosshideout.com/how-to-adjust-needle/ No pressure, John, I can imagine how difficult that must be...
Yeah, the low coolant can be caused by several things. Usually it's from overheating from low speeds/clutch use/not enough air flow. A lean main jet is one possible culprit, although not as common.
i’m restoring a 1982 honda xr and just put a new carb in there. I keep adjusting air fuel mixture, and changing main jet going from not starting at all or it starts very well but redlines instantly and won’t come back down. I’m taking notes and turning air fuel mixture slowly but still, too much revs instantly or won’t start at all. Any tips?
Main jet doesn't really matter for starting and idling. Sounds like a possible air leak. Cracked air boot/intake manifold, loose carb clamp, fuel screw o-ring cracked/missing, or a cracked/missing a gasket/o-ring. That's what I'd check first.
What about revving to the moon after a rebuild? Is that a jetting problem? I’ve messed with air screws, replaced rubber boots, new carb, and cannot figure it out to save my life. Any help is appreciated
It didn't do that before the rebuild? It does sound like an air leak. Does it do that just when you first start it up? Any chance the throttle cable is pinched/stuck open or the idle screw turned in too far? It doesn't take much for it rev up high.
@ I didn’t own it before the rebuild so it’s hard to say. But no the throttle is closed all the way. I haven’t run it long enough to see if it will idle down because it revs so high I don’t want to blow it up. I’m just thinking it’s a jetting issue or I’ve heard some crank seals or some other seals or reed valves can cause this. The bike has new intake boot and everything though, it doesn’t make any sense
@@redneck24-65 Okay, I would maybe try start it and tapping the kill switch to keep the RPM down. If it wants to keep revving after 5-10 seconds, there's likely an air leak or the pilot might be too lean.
@@MotocrossHideout it is a cheap carb, so I’m thinking it has to be that. If something wasn’t put together correctly in the top end, could that cause it? I wouldn’t think so, I’ve built a couple of these and never had the issue.
This has nothing to do with the video but do you know how to make ur dirt bike quiet? Bc I have a 110cc and it’s pretty loud and it annoys me and it’s loud for my neighbors bc they complain all the time abt it 😂

That low coolant / lean jet sounds interesting.
I’m new to radiators.

@ okay, yea I’ve done that with the kill switch for maybe 20 seconds a while back. So you think it could be pilot jet? Not the main jet?

Best way is with a different exhaust pipe. More specifically the muffler. If it doesn't have packing or a baffle system, it's going to be loud.
