It seems to me that the answer to the riddle would be the sum of Phil and Jim's thoughts. <!--EZCODE EMOTICON START :p --><img src=http://www.ezboard.com/images/emoticons/tongue.gif ALT=":p"><!--EZCODE EMOTICON END--> <p></p><i></i>

Jim,<br><br>I hate to badmouth but I have had that particular experience with cometic gaskets a few times. I've also on my second oem gasket that I have had to modify with a dremel and neither has ever given me problems. <br><br>I could sit in traffic on a hot day and let the fan cook my knees and i...

Getting back to John's question on improving hp.<br><br>There are two ways that you can go about increasing the output: <br>1. fatten the torque curve (head work, possibly higher compression, supercharging)<br>2. shift the torque curve higher up the rpm range (i.e. new R1)<br><br>You mentioned that ...

Thank you exupjon, that proves that the specification is not consistently above, or below the cast in line throughout the various models that were offered. <br><br>The specification is very dependent on how much the carb assm. is tipped from vertical. Obviously, this is not a problem on the stock bi...

I apologize Don, but I am a little skeptical about the fuel level measurement being above the float chamber line. The reason that I am is because I have the 1987 fzr1000/750 and 1998 R1 Yamaha shop manuals and in each case the measurement is below the cast in line. Can anyone else verify that the le...

Get out the rope boys - it's time for a lynching...........<br><br>You are very correct Bob, the brass tube in question is the fuel supply line to the choke valve. Since no particular model/year was mentioned, I deduced the purpose to the line based on its described position. This was a very open th...

no, it's not.<br><br>You need to clean the orfice of each jet, blast out the passage ways and anywere it might impede movement. <br><br>I would think that you still need to remove the carbs, or the epoxy/glue will ooze away. <p></p><i></i>

Well,<br><br>First off I would try to avoid using wire to clean out jets. Try to use carb cleaner and an air hose. if you need to persuade some stubborn deposits try to use a piece of nylon bristle. <br><br>You didn't mention the year/model, but your description is thorough enough for me to venture ...

Sounds to me like there is a little administrative power play going on based on semantics. Let's keep it civil and settle things with an arm wrestle. I'll assume the role of the bookie. I'll need some stats to set the odds and we'll need to post promotional pictures of both you guys flexing and perf...

It sounds to me like the dudes bike is Knocking under acceleration. Try some chevron techron to get the carbon out. <!--EZCODE EMOTICON START :smokin --><img src=http://www.ezboard.com/images/emoticons/smokin.gif ALT=":smokin"><!--EZCODE EMOTICON END--> <p></p><i></i>

I've also been thinking about air box tuning for some time. I've Frankenstein-ed my air box by adding on a newer, larger snorkel and filter element from a %%WORD23%u0 on my 87 1000 and I am happy with the result. I've also done some mental excercise on how to make an air box with variable tuning to ...

I would just like to comment on CVH...'s explanation on sparks: the explanation is accurate and masterfully crafted<!--EZCODE EMOTICON START :rock --><img src=http://img.photobucket.com/albums/v209/ ... ock_On.gif ALT=":rock"><!--EZCODE EMOTICON END--> <p></p><i></i>

I think I might have mentioned this before, so forgive me if it's familiar. <br><br>We all like music and are familiar with sound equipment, so I'll use that as an analogy. There are different speakers on the market and I would like to cover two specific types since the way they function is very int...

JJS,<br><br>If you're having a problem with poor running when the bike is damp, I would check the plug caps, and the resistance on the high tension side. Also, make sure that you are running the non-resistive plugs. Use silicone grease on the wire junctions and the caps to keep moisture from creepin...

Indy,<br><br>I could send you a pdf of the tool via email. I don't have a personal website, so I can't post it there. I'm too ignorant to know if there is any other way. <p></p><i></i>

Good call dvs, <br><br>Valve clearance can be a culprit and probably should be checked first. <!--EZCODE EMOTICON START :cheers --><img src=http://img.photobucket.com/albums/v209/ ... Cheers.gif ALT=":cheers"><!--EZCODE EMOTICON END--> <p></p><i></i>

The site is a great tutorial on how a carb works and for the most part can be applied to street engines. The tutorial deals with motocross carbs specifically and these are somwhat simpler than the CV carbs on street bikes. The only thing to consider is that the throttle position is not directly link...

MyYammi,<br><br>MY 98 R1 service manual lists 1.5 - 2.0 in. for slack. I thought that was excessive too, so I tried going a little tighter. That made the chain much too tight when sacked down from my weight. The swing arms on the new bikes are much longer than the fzr and they slope down considerabl...

You're suspicions are correct. that rpm is mainly controlled by the pilot jet circuit. These can be changed out also, but in most cases you wouldn't have. Change them only after you're sure about the main jet/jet needle combo. <p></p><i></i>
