Kx250f engine swap?

[reckless]

forgive the rough drawing. the space the yellow is at is where you can run a yfz450 radiator. the black lines are frame tube location and engine mounts. this I what I have so far. I wasn't and wont knock anyone on design and this is just my take on a swap.View attachment 23021

Also the black line you have drawn could of went underbeath water pump houseing which wAs making engine lean back.

A four stroke engine is massivly taller than a two stroke even lent sightly forward i had to modify tank to acommodate it, keeping those bars wouldnt work, i tried i wanted to alter the least possible
