Why 17/45 Sprockets on Hawk 250?

I know I would have to cut the chain but that's easy stuff. This would shorten the chain by 20 links. Shorter chain less stretching. The 45 tooth sprockets are $25 and not in stock but I can get a 40 tooth for under $19. Has anyone done this combo with any issues? Just think outside the box.

I always prefer to take the reduction on the rear wheel on unit construction m/c power plants. A larger front sprocket is easier on the chain. Although you should fit a new Uni-bear chain or one of equal quality, sooner rather than later.
