Howdy folks, I just joined today to ask this question but first want to thank everyone here for sharing your stories and experiments and ideas. I've been learning lots from many of you since getting a used GT-5/mtnbike combo a few weeks back. This is one of the best forums I've found online of any sort, less flaming and more useful info and good humor than on most. You've already saved me money and time, and maybe once I learn some more I can repay the flavor.
But enough with the niceness. Question is, how bad for a carb is it to run it without the cover? It's a GT-5 made in August 2010 and came with the red cover carb, not sure if it's speed or the other one. The motor was missing a fair bit at mid-throttle when I got it, so after changing to the forum favorite NGK B6HS (helped a lot for only 1.99 at O'Reilly down the street), I took off the carb cover to see if it was clean, and put it back on tight, where it stayed for a few rides and dozen miles or so.
Yesterday I found a post here saying that the guy was having more luck at WOT with his choke wide open too, so I tried it and suddenly it was pulling nice and hard for me, too fast in fact for safety's sake (the bike just doesn't feel like it was meant to go much over 30). But then when I stopped I saw I had no red cover, nor the black plastic gasket that was under it. I screwed it in real tight, so how did it come out? No idea, but I did put in a tablespoon of Berryman's B-12 in a full half-gallon tank the day before. Might that have dissolved some plastic or...? Weird.
Anyhow, I had to ride it home and it went just fine. I saw on another post here that someone said they'd had better luck with this recalcitrant carb (CNS, I think?) with the cover off. But that seems likely to get dirt and dust in the carb and engine. Or not? I guess I'm going to get an NT or maybe one of the dax dellortos, but I really want hill power more than top end.
Should I not ride it until I get a new carb? Or is it good to go and I can just keep going until the new carb?
I really appreciate any opinions, and once again thanks for making this such a very useful forum.
Ride on!
