I know this maybe a crazy idea bc the money I'm going to have into this, I could just go buy the bike I want but I have always been into crazy bikes. I currently own a 03 gasgas fse 450 but I have had constant issues with it but when it runs it the funnest bike I have rode. Its light and powerful but just a riot.. so I want to keep the bike bc it is off the wall. I want to put a drz or rmz motor in my gasgas fse, I want to go with the Suzuki motor being all I read is that its basically the same engine but the gasgas engine has more power.. but I'm looking for the reliability.. everytime I take it out it leaves me busted.. so here is what I'm hoping for, if someone know what engine would fit. Needs to be a 450 but something that I can run a headlight/ tail light, to keep it on the street or the trails more street though. I am also hoping to get rid of all the bells and whistles just get a straight kickstart with a carb. The bike currently has electric start, fuel injection but these are all issues on the gas gas. Any ideas thoughts or complaints to get this project rolling would be great help. Thank you for the time
