02Bansheeee Posted January 17, 2014 Report Share Posted January 17, 2014 I just finished a full rebuild on a 99 Shee' and when I was breaking it in, with a mixture of 16:1 from the book, I checked the plugs and the left one was fine but the right one had a little black place on it & the rest was white other than the sparker? The bike was seeming to run fine, smoking a little less on the right though, not much less. & I recall the right plug being lean when I disassembled it, could it be something I did wrong or is it a simple air screw fix? Help please! Quote Link to comment Share on other sites More sharing options...
02Bansheeee Posted January 17, 2014 Author Report Share Posted January 17, 2014 Should I check compression? I really hope it is just the air screw. Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted January 17, 2014 Report Share Posted January 17, 2014 You KNOW the first 50 responses are going to be "Do a leak check" So….Do a leak check. Then start asking questions. Because if you have an air leak….that was the cause of the first problem and possibly the start of your second problem. it should hold 6 pounds for 6 minutes. If not….find out why. Then get back to everyone with an update. Quote Link to comment Share on other sites More sharing options...
Young Guns Racing Posted January 17, 2014 Report Share Posted January 17, 2014 ^ ^ ^ this. A compression test before hand wouldn't hurt. Quote Link to comment Share on other sites More sharing options...
wayne_smith97 Posted January 17, 2014 Report Share Posted January 17, 2014 Running 16:1 without going way up in jet size will make it lean. Compression test Leak down Then carb check Reduce to 32:1 mixture Quote Link to comment Share on other sites More sharing options...
02Bansheeee Posted January 17, 2014 Author Report Share Posted January 17, 2014 Alright, I'm going to do a compression check tomorrow. & so if the compression is good, I still need to leak check? & like I said I brought it blown in November and the Right plug was lean during disassembly. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted January 17, 2014 Report Share Posted January 17, 2014 Yes. ALWAYS do a leakdown before a tear down and after assembly. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted January 17, 2014 Report Share Posted January 17, 2014 Did you fully disassemble and clean the carbs? Also verify float height is 20mm +/-1mm. Quote Link to comment Share on other sites More sharing options...
02Bansheeee Posted January 17, 2014 Author Report Share Posted January 17, 2014 After I started it up today and went through the gears at lower rpms like the book said, the plugs panned out to what the book said they should be. But it's also doing some crazy thing intermittently by cutting out like you're hitting the kill switch and catching itself again every once and a while, it died on me 2x but started back up. It happened while warming up sometimes on choke, while idling some, and once while I was finishing the break in by doing a bit of opening her up. I'm still gonna do the compression check and other things that you guys recommend. Quote Link to comment Share on other sites More sharing options...
Sandking Posted January 18, 2014 Report Share Posted January 18, 2014 So everyone told you to do a leak down test and you ran it anyways? Good luck you could be ruining a new top end. Sent from my SCH-I535 using Tapatalk Quote Link to comment Share on other sites More sharing options...
02Bansheeee Posted January 18, 2014 Author Report Share Posted January 18, 2014 Can the leak down tester be made? Or do I have to buy the $60 one. & it wasn't run long, because I only had one step left. Quote Link to comment Share on other sites More sharing options...

You can burn down a motor at idle with an airleak. Quote Link to comment Share on other sites More sharing options...
03DMshee Posted January 18, 2014 Report Share Posted January 18, 2014 while I was finishing the break in by doing a bit of opening her up. Listen to what people are telling you...meaning dont start the fucking bike again till u perform these tests....if you have a leak you will have to do a leakdown again...only 300 dollars later Quote Link to comment Share on other sites More sharing options...
02Bansheeee Posted January 18, 2014 Author Report Share Posted January 18, 2014 Alright, i understand that I shouldn't have started the bike. I'm not going to again until these tests are done. I will get back after I do a leak down test. Thanks. Quote Link to comment Share on other sites More sharing options...
