[Honda XR150L - cold start issues]

Unless you noted where the idle screw was before messing with it you'll have to get it running and warmed up to reset it.  Ideally with a tach, but you might get it close enough by ear.  The manual should show the cold start procedure.  Typically it would be- full choke to start, drop to half choke to warm up, choke off when warmed.  Only starting with no choke tells me something is very wrong with it, or you're using the choke backwards and actually full choking it when you think it's fully off.

 

Most modern carbed bikes have a very lean idle mixture for emissions.  The idle air/fuel mixture screw is probably covered so you can't mess with it, another emissions thing.  It 'shouldn't' need adjusting, but it might benefit from a small tweak, especially if you're at low altitude where it would run the leanest.

Agreed - for $3K you’ve got to level set your expectations.

I would call the dealer and speak to the service manager.  Ask if this is a common thing and is there something you could do or possibly talk to a mechanic.  They might just say to bring it in or maybe give you helpful info. 

I was trying to avoid that but think I may take your advice before I start fiddling with a brand new bike. Appreciate it.

A few of the Chinese models were actually more than the Honda but they also had a few that were less but visually looked like toys and junk.  I paid $3100.

It's known with this particular bike... I got that from a simple google.  The choke is not your typical choke where you pull a level it's a clicker with 3 set positions - Off, Middle, and High. High... it won't start at all and middle it starts but really no different then with it's off. 

 

I'll back off the idle speed back to where it was when it would start and stay started for a few seconds then die. Hitting it a dozen times like that... it will stay started a "touch longer" each time until it stays on.  

 

Fast forward to 27 seconds... his started right up but you can get a feel for how LOW it idles.

LOL.  Yeah, exactly.

 

So raising the idle speed opens the throttle, which during start is making it even more lean.  Then you choke it to forcibly add more fuel through suction, and everything goes fucking nuts and unpredictable.  Get the idle speed screw back to normal.  I assume there's no visible/reachable idle mixture screw?  Try this method:  Start with the choke open, hit the button, and turn up the choke slowly until it starts.  This will let you find the right mix for that moment.

 

Also, fuck carbs.

 

 

I believe this is the idle screw (I'm sure of it)... it's the one I turned to raise the idle.  So you are saying to open the choke all the way... and back the idle down (counter clockwise on that screw) little by little until it starts or leave the choke off and get it back down to where it was?  

 

Thx

Very helpful, thank you!

[Honda XR150L - cold start issues]

Fouled?  With 2 miles on it?  It's a single so there is 1 plug and I'll check it. 

 

The battery is huge for this small bike, so it's not the push.

I knew someone would tell me to bring it back... I just hate dealers. 

[Honda XR150L - cold start issues]

When I hit the starter button it takes 10 or 12 pushes to get it to start.  Once it starts the idol is extremely low... to the point it sometimes stalls. There is a 3 position choke, up (high), middle (medium) and low position which is no choke.  In the high position it won't start at all.  The middle position doesn't really work either. 

 

I started adjusting the idol screw (clockwise) to increase the idol and now it's even harder to start.  I'm going to adjust it back down so it requires a lower idol to stay started.

 

Any suggestions?  Seems as if this is a known issue and reading that a lot of people change out the carburetor... which, I will not be doing. 

 

Thanks

Not that I care - just want to make sure it's correct.

Lol. Use a small tape measure.

Buy a 2023 Toyota Tacoma. 
 

Remove the hood insulation pad from it, install it on the Mazda. Take the mouse eaten one and put it on the Tacoma and return it. No one will ever notice.
