Hey all,
Let me start off by saying I've done a lot of research on this forum, and unfortunately, I'm making this thread because I couldn't find anyone describing symptoms similar to mine. If a thread like this already exists, I'm sorry -- please delete this and link me to that thread.
I bought an 02 Blaster the other night, for a good deal, knowing it needed a bit of work to get it up to par. The motor revs out FULLY when either the clutch is pulled in, or when it's sitting still in neutral. If I am in gear, and go to give it gas, I can get all the way from 1st, to 6th gear, but only on a flat road, and just burbling off the bottom.
My first thoughts were to check the reeds, but they're perfect -- not cracked at all. I will say though, they were pretty wet, which made me think one of two things: 1.) The main jet might be too big, but that doesn't make sense because the bike is bone stock and the kid who owned it before me never made one engine modification -- or 2.) The TORS might be goofing up, and intermittently cutting spark, so a bunch of unburnt fuel is building up.
Also, I'd like to note the air filter on this thing was brittle, dry, and cracking, and I wouldn't be the least bit surprised to find out that a piece of air filter got wedged up in the carburetor somewhere (possibly main jet) causing these issues. Another theory someone came up with is that since the air filter on there now is so disintegrated, that there's not enough airflow restriction, creating a lean condition, and what I'm experiencing is the main jet not being able to keep up with this extra load of air coming from the airbox.
I'd like to pull off the carb, and see if the main jet is clogged; I started to take if off last night, and got the carb cap unscrewed off, but there was this one thin black wire getting in my way, and also I didn't know the best way to disconnect the oil injection line going into the carburetor.
Any help would be greatly appreciated! I want to approach this methodically, and not get too far ahead of myself wasting time + money on a leakdown and/or compression tester, etc. But at the same time, I don't want to create engine damage in the process of troubleshooting.
Thanks,
Colin
