hi guys I just bought a brand new carburetor for a YTM 225dx. when I bought it I thought it was a actual Mikuni but instead it came back as an OEM STD carb. I ordered two main Jets from Dennis Kirk 115 and 117. 5 to rejet it for my exhaust that is on it. the Jets I got from Dennis Kirk are fine thread why the main jets in the new carburetor is standard coarse thread but at the same time the Jets are all the same size on dimensions do they make one a standard course or am I screwed on this new carburetor I'll send a detached photo of the Jet from Dennis Kirk that gives you all the dimensions but just need the standard course thread I only bought a new carb because I kept having problems with the old cards. if anyone can help me with this just post to this thread thank you in advance i hope someone can and will be willing too
