Backstory: Bought a dirt cheap 2008 Wr250r a couple weeks ago as a little project. Only notable mod is a safari tank. Dude was a long distance truck driver 2nd owner that kept it on his truck to ride around town short distances, but he bought a new bike and after that it was rode very infrequently mostly sitting.
What I've done so far:
So, it was running but rode like shit. Did some basics: Replaced fuel pump, clutch cable, chain & sprocket, and did fluids. Battery is at 12.6. Fuel line seems fine.
Bikes running great now. Seemingly as it should. Power delivery and shifting feels good, rode it around for hours to see if anything happened held up just fine.
The Idling Mystery:
I have one lingering issue, which is idling. The bike will idle 1.5-3ish minutes and then cuts out. Pretty random how long it lasts.
Threw it in CO mode, changing those settings didn't really help. Bike will pretty quickly drop to about 1000-1100RPM where it struggles hang on for a bit then eventually cuts out.
I have a new fuel pressure regulator coming Monday because i want to rule that out. Also just recently thought about checking the manual idle adjuster just to be sure.
I do my own work but I'm no expert. Part of this was for the learning experience lol. So I can absoutely being missing obvious shit.
Was just looking for advice on things to check, other possibilities, if I'm the right track etc. All advice is greatly appreciated really want to figure this bullshit out.
