4 Stroke running HOT!??

[RyanRX7]

What would cause your trike to have the header pipe right where it comes out of the engine glow orange (not super bright but noticeable)? My plug is also a little white (running hot correct?). Should I go to a colder plug? Would an exhaust leak or improperly adjusted valves do it? Any ideas guys? Thanks

sounds like your running way to lean....don't run it till you re-jet and play with the carb

Yea my friends snowmobile is doing that, he said the begining of the pipe was cherry red. Is it the same problem??

yes you are both running lean, the plug should be a paper bag brown colour, search the fourms for jetting there are ALOT of topics on it

Hey I bought a bigger header pipe and a cobra exhaust for my 86 200x a year ago, and it did the same thing. All I had to do was take the top off the carb (where throttle cable goes in) and move the needle down. What I mean by this is: The trottle cable attaches to the slide. In the slide there is a clip which holds the needle. You take that clip out and then the needle comes out. Next, theres a small half moon clip that makes the needle only go through the slide so far, if you move the clip UP, the slide should go UP making more gas flow into the engine and not run so damn lean.

I had to go all the way to the top of the needle with my half-moon clip thing (damn it i 4get what its called now, but i KNOW IT lol) But now my 200x runs like a champ and havent had any problems yet! Go one notch at a time till its right is what I reccommend.

Anyone feel free to correct me on this, I havent done it in a year or more but I think I have the up/down directions right. It COULD be the other way, as in move the half-moon clip down on the needle. Either way theres only 5 notches to put the half-moon clip in, move it whatever way makes it not overheat, lol. But so this one at a time because too much gas isnt good either.

that would be the jet needle i think...

I looked into moving up a jet size but it seems it came with 135 stock and bike bandit only shows the factory offering 132, 130, 128, and 125 as other optional sizes. I would need something larger correct, what should I do?

go to the local honda dealer

OR, try moving the needle up/down cuz you more than likely dont have to rejet....I went through the SAME thing man, just play with it, its so easy to do.

More then likely he DOES have to jet up. The needle only works the mid range. Mid range to WOT is mostly your main jet.

[roger86200x]

well, if he isnt running WOT then he wouldnt have problems you are saying?? if he starts it, rides it, shuts it off, then starts it up after the pipe stops glowing and it tursn red again then he doesnt need the jet, if it only turns red when hes riding and not idling then jet--according to you

I'm not saying anything is according to me, it's according to the way you tune a carb. If you do a search on carb tuning I'm sure you'll find some good info and maybe some charts. All I'm saying is it gives the wrong impression to only advise adjusting one part of his carb. The second anyone has a lean or rich problem they should be checking everything; air/fuel screw, needle and jet. Most likely if one part adjusted that bad, the rest needs attention too. Now in your case, if you had to put your needle all the way up I'll bet your lean at WOT. Changing jets will affect where you needle setting is too. With the right jet you wouldn't have to be where you are.

[roger86200x]

lol, dude I was lean just idling, and my WHOLE pipe up to the muffler was glowing CHERRY RED...all I did was move the needle position and POOF it was fixed, and I have NO more problems and it runs GREAT!

[83185s]

if that doesnt solve your probs then it could be a few others...out of time, incorrect plug, or too low of an octane...i learned that today in transportation systems! lol..although somehow its completely different with quads and trikes and stuff..thats for "small" engines...lawnmowers and what not..but you never know

[MTS]

as i said, search for carb tuning threds and you will know what you have to change ect ect...
