Hot Start troubles

My Son has a CRF150R and it is a bit hard to start when it is warmed up.

 

Is this normal or do I need to do some adjustment to the Carb?

 

Thank you

It's been way hotter than normal for this time of year here. How about in Texas? It could require one or two sizes leaner on the main, and half a turn or more leaner on the pilot. If not, it could make the hot-start valve ineffective.

Inspect the hot start lever, cable, spring and slide to ensure it is working. I'm at 400' above sea level and run a 138 main and 42 pilot and temp has been in the 90's and mine starts on 1 or 2 kicks in gear when hot using the hot start. The R&D flexible fuel screw is a life saver, no more burned fingers, I would suggest it if you don't have one.  

Also check your valves. Flexible fuel screw!

I bought the bike off the showroom floor in El Paso 2 summer ago and moved to NC where we are about 100-1400 feet above sea level.                                                                                    

 It was a bit moody in TX when it got warmed up but; here it seems to be more "moody" that usual here in Fayetteville NC.

Between the two states there should not have been a major change. I suspect valves and poor jetting. Have you or the dealer changed jetting? Was the bike new when you bought it?

Good man: that's the way to help!

I am going to check the valves tonight, base line all of the adjustmens on the Carbg, and see where it goes from there.  I am going to the track on Saturday so the kids can ride.  I will tinker with it there if and see if I can dial it in a bit for elevation and humidity here.  Also going to adjust the suspension a bit.

What track are you heading to? I'll probably be at Outback on Saturday with my wife and kid

I am heading to Outback.  Going to leave early Sat morning to try and avoid the madness and let the kids ride before it gets too hot.  Both boys are on Hondas crf80 and crf150r

I'll be there with my wife and son. She'll be on the 150RB with #51 plate, boy will be on CRF50. I just traded mine for a motard RB, not sure if I'm going to bring it out... Thought about running it on the oval tho.

Matt,  Ill be there in a White F350 with a cap on the back CRF150 has #61 on it.  Fresh gas and some basic cleaning seem to have been the culprit so far; lets see what it does after it gets hot tomorrow.

Track is pretty sweet this morning... I'm the white Silverado parked next to MX track entrance
