Hello, first time on a forum, just got a custom 1980 sr250 bobber, been a real learning experience. Look forward to learning more on here

I actually kinda figured that, gonna get one tomorrow and see what happens, thanks for the advice guys , I'll repost the results later

Rejetting*

Adjusted pilot screw in all the way them out 1 and 1/4 the 1 and 1/2. No air filter, gotta get one. May try soaking carb, idk what else to do besides maybe rejecting carb

Ok, done valve adjustment, tried 3 different plugs, cranks and runs on half choke, runs for a while and shuts off off choke and still spits and backfires when I rev it and let off, could there be a spark problem, electrical issue. I'm at a loss ,really need some advice here

Ok, I adjusted the intake valve, ran a lot better, but went back the same after a lil while, I've tested compression before, had 150 psi

Also it has a CDI box so timing shouldn't be a big issue according to what I've read....?

Odometer shows about 5000 but there's no speedo cable, so not exactly sure, but it's got to be close,I got this bike on a trade and just trying to get it riding, I'm kinda new to bike engines, any help on adjusting valves etc. would be very helpful

I have a sr250 custom bobber, I've cleaned the carb multiple times, still doesn't help much. It will crank and idle, was only running only on half choke, it will idle and ride now with choke off but still wants to spit back through the carb and backfire, also wants to shut off sometimes at stops. How can I fix this?
