I am new to the forum and just purchased a used 2015 Coolster ATV-3125r. It is 125 cc with automatic and reverse. I will present my problem and questions in the Brand discussion area... Bye

Well, it said go to Brand discussion area for probs/questions, but I do not see here how to get there. So, I will present my discussion here. As I said I bought a used above referenced ATV, took it to a shop and had it tuned up. The mechanic says the engine is shot and will not last long. My question is, can I replace the current 125cc engine with a larger 150cc engine into the current 125cc chassis? If so, is there a video or some instructional that will lead me through the change over? I am a mechanical retard. Would appreciate any help you can give...

 

Welcome to the forum! I know zip, nada, zero about the "Coolster 125" But if it is Chinese, check the Chinese forums.

 

Hello: If you think you are a mechanical retard now, you won't be thinking that after your renovation project on this old ATV. If someone says the engine is "shot", they probably did a compression check on it, right? An engine will run if it has compression, fuel, and spark... plus a few many other things. Confirm what you were told.
