Just a little thread for if you Guys think I should build a ported 3mil with a right bend or make a turd yz 490 nice and modify my frame
Don't know how to make a poll from my phone
 
Go with a ported 3 mil. It will be so much easier and more practical. Modifying your frame involves tedious measurements and requires near- perfect alignment. Ported 3 mil will be your best bet. 3 mil cranks don't require case trenching, and provide a huge power improvement
 
I would go with the Blaster engine. If you do go with the 490 engine, check into a compression release. A fresh YZ490 can hurt you before you ever get it started.
 
blaster motor is kickass, but honestly are you even serious about thinking of installing a motor thats almost 500cc's. Not even kinda overkill its WAYY too OVERKILL, kinda sapprised someone would think of it, do u realize the work involved in installing it or the amount of vibrations that thing would put out. a 250 motor would be more relistic, im sorry a 490 motor in a blaster would suck it would be like intalling a ls1 in a mine cooper it would be fun but lets face it would suck.
