Ladies and Gentlemen,
So begins another repair post. I always think I will be able to fix these things and end up on the forums. So here we are. I will put up some pretty pics and vidya tonight.
Took an 09 CRF230M on a trade. Want it to be a city bike and maybe take it to some kart tracks for fun. It was a NY state bike and by the time I got it it in Denver, CO had 6000mi and was running poorly.
Mods: spark arrestor removal, backfire screen removed, smog removal kit installed.
Issue: immediate cutting off of power past 1/3 throttle. I'm talking instant burbling and loss of power. Will recover and idle fine afterwards. I was having issues with motor heating up and spitting oil out of the case in to the airbox (seems like lean condition).
Diagnostics and changes so far:
New plugs are slightly black, not oiley
150psi compression
Valves adjusted to spec (exhaust was slightly off)
Strong battery
Needle 1x .5mm washer up, 38 idle jet, 2.25 mix screw out, 100 thru 130 main swapped to no avail
I did the smog removal myself with the kit and the vacuum lines are my primary suspicion. All of the pictures from years ago are no longer hosted so I can't compare.
Second suspicion I have is the ignition coil but I can't find any resistance specs for it.
I may to restockify the smog stuff and start from there but it was having issues prior.
Sorry if this is a ton of info, I try to be relatively thorough with the initial post... Thanks for any help!
