I want to install a cooling fan on my bike. Has anyone got any ideas here. I would like to install a battery and connect to the bike's stator wiring for recharging.
Thank You

Welcome to the site !!

The stock stator will not power a fan , nor allow you to charge , the bike will need a aftermarket stator (the 450X stator will not work either as the flywheel is too large for the R ignition cover) ... Your best bet is to contact Trail Tech and tell them what you want , and what specific fan you plan on using , or they could set you up with a complete kit including a fan ... they have small battery packs (they are basically R/C car battery packs) , so they take up little space , though with the regulator and other stuff , it is usually set up behind a headlight they provide , not sure if you want that or not , but I guess you could always take the components off it and strap them down somewhere on the frame or subframe......

But your best bet is to contact them , as of right now with a stock stator , unless you buy a 17-21 450R , or a 450X (or 250X) , you can't have a fan nor a battery ..... ...

Though as a additional help , ...... , You can mount a overflow tank on the bike (I did one on my 02 450R using a 04+ 250X overflow bottle and hoses and mounted it on the subframe....*pictures below*) that will at least put the coolant that blows out , back in the radiator for the most part ... also get a higher pressure radiator cap , stock is 1.1 bar , you can get a 1.6 or 1.8 or 2.0 bar cap , each higher number raises the pressure as to when the cap releases fluid , and Engine Ice or Evans Waterless Coolant will help raise the boiling point so it does not boil over as easily , so all that will help a lot as well , with that stuff mentioned alone without the fan , I did lots of single track with my 450R without any issues , I never put a fan on it and rode it for 12 years like that and never blew a head gasket ... I did put one on my 450X .... ....Hope that helps ...

Thank You very much. I purchased the bike to ride with my grandsons in NM not knowing the bike does not like the slow stuff. I will definitely make the changes.

If you are going to just be putting around for the most part , you might look into trading it off , or selling outright and getting a 250 or 450X , you can add a fan and higher pressure radiator cap and Engine Ice , and maybe gear it down to a 13/52 or 13/53 (stock is 13/51) which will allow you to go slower without lugging it as much , and it is electric start so it just makes it nicer when you do stall it .... then you can go where you want when you are not riding with him and want to rip around , but still have a bike better suited to go slow , and as he gets older and better you can go on adventures in the woods or desert together ..

Well i am going to give this bike hell at the end of the month. Going to OMG 100 in Cuba NM. Gonna find out what it's made of. My grand son will be riding a 1994 YZ250 i rode many years ago in NM. It never failed me. Should have done the research on the bike before i bought it.

I am guessing the bike has a 3.2 gallon tank on it ??? , as the stock tank is only 1.9 gallon and will only allow you about 40 or so miles total , where the 3.2 will allow you around 100 give or take depending on speed and throttle input .... But the bike would be better suited to that than slow tight trail riding ...
