View Full Version : EK4 won't wheelie
Yes, I'm a "newbie" to nitro, but I've been reading the forums for 5 months and have tried to "do my homework" before I bought this beast. Anyway, I'll try to make this brief. I took the safe route and let my lhs do the break-in. Two gallons and three days later I get my truck back. Installed MSJ starter. MC59 plug, Coolpower 25, 2 3/4-3 high, Mid-flush with carb housing, 2 1/2 low. I've tried to stay around those settings and have stayed below 250. Piston and sleeve are fine with plenty of lube but I don't want to go too lean and kill it. Rear diff is fine and clutch was changed after break-in. Seems to have plenty of power but just doesn't have the punch to throw the front wheels in the air. Everyone says it will wheelie even slobbering rich. What am I doing wrong? Do I have another bad clutch? Any help or even constructive criticism would be greatly appreciated.

first off I would have you back the high speed out to about three turns out and then I would have you lean the low end out 1/8th turn until you get her to pull the wheels up and throw herself. You can lean the high end down to 2.75 turns but I keep mine around three and a quarter and my motor stays at 200-220F with the fridge head. I have to say that it reacts so violent when I punch it I wonder how hard it did not snap something when it would slam up in the air and lean on that rear bumper. Give that a try. I hope it helps just keep in mind all nitro motors are different and keep it as rich as you can. :cool:
Thanks Mt Killer. I tried that setting with same results. Not sure I should have to be dialed in so precisely to get the punch out of the hole. I remember when my lhs changed my clutch after break-in, I don't think they deglazed the clutch bell. Could that have glazed the new clutch shoes? I'll try some emery cloth tonight. Also, do you think my temp is right considering my carb settings and stock head? I've heard anything under 300 is safe as long as there's enough lube.
Come on. Someone must have some input. At least let me know if I'm getting warm. Do you think it's my clutch or what?

Does your truck rev up or bog down when your trying to lift the front up? I used 800 sandpaper and deglazed my .21 clutchbell. It seemed to help a bit.

...sure. Make sure all of your tires are glued VERY well...if not, they'll slip and that'll reduce the likelihood of hard acceleration and wheelies. The clutch can be a factor too.
Also, how stiff is your back-end suspension? If you did not add spacers in the rear shock and it is too bouncy, that'll reduce your wheelie popping ability. Stiffin the rear-end up and you will notice more wheelies. I cannot get good performance with low-end 2-3/4 out. I have mine at 1 3/4 to 2 1/4. I don't suggest leaning out the top end too much, but try to lean out the low-end on one of your running sessions. Take it down to 1 3/4 taking note of the engine tone and see if that puts more snap in it. Keep in mind to give a few seconds for the engine to adjust between setting changes.
