lincster Posted November 24, 2003 Report Share Posted November 24, 2003 Well guys, On the last trip back to the trailer, I was going kind of slow when I could hear a drastic sound change, it was my 2:1 Air Filter coming off. I stopped pretty quick, but obviously it was too late. Sand in the motor. So, I haven't torn it apart yet, but what is worst case? Could it have gotten into the lower end? It didn't seize, but......... My other concern is the carbs, are they shot? Or can you just clean those up and use them again. Any and all inputs would be appreciated. Especially if someone has gone through this before. Quote Link to comment Share on other sites More sharing options...

Cotton eyed Joe Posted November 24, 2003 Report Share Posted November 24, 2003 Had something similar happen to the wifes bike when she had it. We had ridden to the far east end of St Anthonys from Egin lakes, when we noticed her 2:1 came off. We had no choice other than put the filter back on and ride back to camp. No problems ever on that bike. Just lucky I guess. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 24, 2003 Report Share Posted November 24, 2003 As far as getting into the bottom end .... the fuel goes to the bottom end before it goes into the top. If you caught it that fast, you may not have a problem. If you're really concerende, you could take the topend off and flush the bottom out really good. Doesn't sound like you would have pulled in very much though. After you do what ever you choose, (take it apart or just clean the carbs and run it), do a compression check. You're carbs should be fine, just clean the up and use compressed air. Quote Link to comment Share on other sites More sharing options...
lincster Posted November 24, 2003 Author Report Share Posted November 24, 2003 fixitrod, What would I clean the bottom end out with? Would it be easier to pull the whole motor out to take the cylinders off if I need to? Thanks Quote Link to comment Share on other sites More sharing options...
boonman Posted November 24, 2003 Report Share Posted November 24, 2003 I clean with WD-40, and compressed air. Alcohol would work as well. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 24, 2003 Report Share Posted November 24, 2003 I clean with WD-40, and compressed air. Alcohol would work as well. I agree with boonman. It's easier to take the topend off with the motor in the bike in my opinion. If you want to take the whole motor out, I suggest taking it apart on the bike... clutch side, stator side, and top end, then pulling the motor out. It's a lot lighter and easier to handle.

lincster Posted November 24, 2003 Author Report Share Posted November 24, 2003 Ok, I am not picturing something here. If you spray WD40 into the bottom end and the motor is still in the bike, where does the WD40 go? This is probably due to me never taking a bike that far apart.

fixitrod Posted November 24, 2003 Report Share Posted November 24, 2003 You should be able to blow most of it out. If you really want to clean the crank though, you'll have to split the cases. You still may not get it all out because there are bearings in the web of the crank that you may not be able to get to very well to clean them. How much sand made it in there? You're making it sound pretty bad. Quote Link to comment Share on other sites More sharing options...
lincster Posted November 24, 2003 Author Report Share Posted November 24, 2003 I don't think much, but I am a pessimist, so I am expecting the worst. I'm going to tear it apart tonight and see what I can see. I know putting my little finger into the reed cage came back with hardly anything.

lincster Posted November 25, 2003 Author Report Share Posted November 25, 2003 Ok, way cool. I just pulled the carbs and reed cages off. There was NO sand or anything on the side of the carbs going into the reeds and the reeds looked perfect. Cylinder walls and pistons look great. I think I got lucky. Going to clean everything up and put it back together. Thanks for the help. Linc Quote Link to comment Share on other sites More sharing options...
97redshee Posted November 27, 2003 Report Share Posted November 27, 2003 get rid of the 2-1 toomey pos and get a set of pod filters with pre wears Quote Link to comment Share on other sites More sharing options...
KEVPOPPAPUMP Posted November 27, 2003 Report Share Posted November 27, 2003 I run the Toomey 2:1 and the only thing that sucks is having to wrap the outerwear with wire or zip ties so it won't melt on the pipe. As far as the filter coming off while riding, where is it coming apart from? I use automotive hose clamps on everything from the intake manifolds back. The Toomey large clamp for the filter to the rubber works good providing that you firmly snap the filter into the rubber. If it doesn't snap in then it will come out. I could see a problem if you used the stock Yamaha clamps to fasten the rubber to the carbs. Quote Link to comment Share on other sites More sharing options...
lincster Posted November 28, 2003 Author Report Share Posted November 28, 2003 It came off from where it clamps onto the carbs. Here is my theory. I hadn't taken the filter off for 3 trips, outerware was still clean. So I think that the oil from the filter, a little ran down the intake tracts and got between the rubber and the carbs and got slippery and came off. Combination of time, oil and vibration. I never thought about Automotive clamps, maybe I will give them a whirl. Any particular size? I didn't think they would work because of the indent in the rubber where the stock clamps are supposed to go. BTW, I have heard of more pods coming off then the 2:1s. I ordered a new on and will run the same thing. To not let the outerware melt, go buy some high temp Silicon hose and put in on your pipes where the filter touches. Then the filter can rest on the hose and you don't have to worry about it. I have never had a problem. I will post pix of it when I get it back together.
