What do you mean "warm up"? Do you mean it won't accelerate to it's full potential? Or it bogs down when you give it gas until you ride it/idle it for a few minutes? If so this is "normal" but don't let a bike just sit there and idle. I usually let it idle until my bare hand gets really warm on the cylinder before I try any full throttle wide open stuff. If you start running it hard before the piston and cylinder are sufficiently [not overly] heated then you could seize the engine. and that always sucks.

You should let it warm up before you go out riding.I allwyas have to let my trailblazer warm up before I go riding or else it will bog.I just crank it and rev it up a lil bit for about a min or so, and then go=)

my blaster did the same thing. Its not because its cold that it bogs a little bit its because its trying to bern extra oil that is seting on your piston because blaster run a little rich. So dont wory about it they all do it its normal.

ALL two strokes have a little bit of warm up time. Them best thing to do it start it and feel the cooling fins. Once they are warm you can go. BUT!!! BUT!!! you should start out slow. Don't just let it get warm and go full throttle. That's just plain stupid! If you just start it and go you will seize the engine sooner or later. Steel and aluminum warn up at drastically different rates. They also hold heat at different rates. Good oil and letting it warm up a bit before riding hard is the key to keeping a 2 stroke running strong for a long time. Also the bogging is caused because left over oil from the last running settled in the cylinder and case. This will cause a gas[img]i/expressions/face-icon-small-blush.gif[/img]il mix to be very rich. That is why it somkes so much when first running them. It will not harm anything other than causing excess carbon build up, but that's a 2 stroke.. nothing you can do about that.
