Default Help with 2008 Honda CRF250X

     

Hi Everyone

I purchased a 2008 Honda CRF250X last year. The bike has run pretty well and is generally in good shape. When I purchased it the prior owner made it clear that the bike worked best to start it with the choke on. That has worked well and as it has an automatic start it generally started right up. Once the bike is warmed up I could generally turn off the choke and it would keep running fine. The last few times I have run the bike it has stopped randomly and it has been difficult to get started again. The starter will only turn over once and won't keep turning over like I would expect it to. I replaced the battery thinking that would help but this last weekend the starter would only turn over a few times and then would stop. I would have to kick start it over and over again with very little success. It feels like there are potentially 2 problems going on here.

1. The starter motor will only occasionally turn over. My feeling is that the wiring might be having a problem but I am not a pro at this. Since the battery has been replaced and the starter will turn over slightly I am thinking it might be a wiring problem. Any thoughts?

2. There is something more broadly wrong with the engine needing to always start with the choke on and dieing often. It certainly has plenty of miles on it but it feels like it dies randomly and is difficult to start again. This one seems harder to diagnose through a forum but I was hoping for some thoughts on what might be going on. Any help?

Thanks in advance.

Start with the carb. Actually start with cleaning the leak/or pilot jet. You can’t just spray with carb cleaner and Compressed air either, it needs to be soaked or poked with a .010” wire or so. Ethanol crust builds up in them and slowly tightens up the hole till she won’t idle at all. May want to look into a hand turntable aftermarket air/fuel screw as well. The stock one is a pain to adjust.

Also load test you new battery. It sounds to be weak. Not all new batteries are the same. Just like anything else, some are better than others. A lead acid battery is old tech and is weak compared to todays LI batteries.

Listen to pawpaw ,think he issending you in right direction with battery and ignition .
If you do not have a volt meter get one ,about 10 bucks at walmart,harbor frt. Etc.
Make sure charging coil is working .
Should show batt voltage not running.around 12.50 volts running ,should climb around 14 .v.
If you idle to rev up and ot climbs and drops volt reg bad.
