I bought a CRF50 (4-stroke) to transition my 4-yo son from the (2-stroke) PW50 that he'd been previously on. It threw him off twice skidding in turns and he's since been tentative but willing to ride it. I'm thankful for that. But I made a parental decision and glad I made it.
I negotiated $50 off for the throttle not snapping back. A $12 Amazon part that didn't fit, 2 weeks at the shop, a new rear inner tube, the shop owner's throttle cable and $150 from my pocket the bike came back home last night. A long way to get to this point, but we're here.
We woke at 6a to get out before the day got too hot and he had his first ride. He rode for about a good 45 mins and went home with a WIN in his pocket. I was able to progressively turn the throttle screw out to give him more range and he was gratified and his confidence continued.
Unfortunately, the condition that I wanted to prevent still occurred. I asked him to stop in front of me (yes, I ask for certain level of precision with putting the bike in specific spots) he couldn't do it. I noticed the bike continued to walk unless he was on the rear brake. I checked the throttle it was still snapping back and even my forcing it forward didn't cure the condition. It seems to be tied to a well-warmed engine, which is FINE when we're running drills but overall is bad.
The bike seems to idle very low, as it should so I don't think that's the problem.
I have a tentative appointment to take it to another shop later today and would love to save the trip, but I'll go if necessary.
