Sarge Quimby 0 Posted October 1, 2021 I recently got a 450 Foreman that my father-in-law had. It runs good most of the time but here recently when it gets hot it shuts off. The fan will kick on from time to time and I have checked all the fuses and they are good. What else could be the problem? Share this post Link to post Share on other sites
jeepwm69 7,751 Posted October 1, 2021 Welcome aboard. We have several guys here who are very familiar with the 450's. @Fishfiles @shadetree do the 450's have a CDI similar to the 300's and old 350's that would cause this? Share this post Link to post Share on other sites

I dont actually know It takes a while for it to do it so it is really not a big deal during the season but when we are working I dont want to have to drag it back.

Fishfiles 20,147 Posted October 1, 2021 Hi Sarge , welcome to the forum ----which 450 do you have , 98-2001 ( 1st gen ) or 2002-2004 ( 2nd gen ) , then ES/FE ( electric shift ) or S / FM ( foot shift ) ----when you say it shuts off when hot , does that mean it will spin over OK , just won't spark and run , or doesn't spin over at all or spin slowly Share this post Link to post Share on other sites
