I ordered the intake manifold on motopartsmax website they say its for cf250 when i got it its not what its for its too long and the vacuum fitting in a lower position.I called scrappydog up we compared measurements from the original there's is the wrong size too. I'm sure its cfmoto it says so on my intake manifold

It should be the correct one.... I very much dislike motorpartsmax. I've used the one from Scrappies.
What part of it is not fitting.... the carb side or the head side? The measurements on the carb side opening from your old one are probably not going to be accurate, as that is one of the places where they stretch. The carb will just "snap" in when you have the right one. How many vacuum ports on the old one? Two? The new on will have one. You just need to get a t-connector from your local autoparts store and you good to go. Where the vacuume fitting is is not important as long as it's there.

Its the length you know the carb side to the head side.It has one vacuum fitting the carb fits in it okay The air filter hose (the J like thing) barely fits into the air filter box.

It should all fit back together but often times you have to finagle them. Usually a few swear words will help. sometimes a squirt of soapy water helps. Sometimes a combination of both. Also, make sure that carb is seated completely... You will hear it "pop" into place.
The air boxes on these bike fit very poorly. I did one that was so bad, we ended up getting rid of the air box and going with a uni filter. Not for performance it fit so bad that we couldn't get it to seal right. Then I had to rejet the carb with a 120 and raise the needle to the bottom notch to make it all work. That bike had a high flow exhaust from the factory.
Something to note, these bikes have been know to be jetted really lean. Mine had a 107 jet in it. To give you an idea, 109 jet is about right for a 150. I'm now running a 115 jet and it's close. Every bike is a little different with jetting so your milage may vary. I'm also 6' above sea level so that makes a huge difference as well. In honda's original design they used a 110 jet, and on the helix forums they constantly complain about these bikes being jetted too lean.
Just some food for thought
