2001 Scrambler 400 2x4
First of all I am new here so bear with me. I recently aquired a 400 Scrambler and I am having a little trouble. The bike runs great with about 1/2 throttle but it cuts out at full throttle. I am kind of thinking it is the jetting but I would really like some opinions. I am having problems with the throttle cable sticking because part of it was rusted, I have a new one on order, but I don't see how this could be the problem. Also the oiler is not being used the guy I got it from said it didn't work but as far as I am concerned I would rather mix my own gas anyhow. I am thinking this may be the problem I have heard that if you unhook the oiler you have to jet it different. Is this true and what do I need to rejet it too, elevation is not an issue I am in Oklahoma? Also I would like to know where I can buy the oiler block off kits I went to the hot seat website and they are like $35, can't you get them cheaper. Is not having the oiler blocked off a big deal, at least until I get a block off kit which will be as soon as possible? I am mixing my gas at 40:1 is this right that is what I always used on my dirtbikes or is this wrong and making me foul the plug? Any input would be greatly appreciated. Thanks.

i would clean your carb really good. sounds like a port is clogged causing it to bogg at full throttle. the jetting doesnt need to be changed if you premix. no need to get a block off kit. take the oil pump off and pull the shaft out of the hole and then put the pump back on. and the 40:1 mix is fine as long as its not bored or ported (bigger surface area and it would require more oil)

Okay sorry it took me so long I had to wait for my throttle cable to come in. Well I have cleaned the carb and no luck. I am wondering if this could be because of the reeds or something like that? Are these powervalve motors? The guy I got it from said he put new reeds in it but I have not checked them. Thanks.
