86 Yamaha BW200...... YTM200 engine performance
Hey guys.... Ive been out of the loop for over a year or so. Good to be back here on 3 wheeler world. I still have my 85 Tri-Z, but I had been spending time on my '87 LT500R.... Now that its all restored and race ready... I have something a little different I am working on. I picked up an 86 Yamaha BW200.... I am gonna rebuild it. It ran, but didn't have much for compression. What can I throw in this thing to pep it up. I'm not expecting land speed records. I figure if I am gonna rebuild it, might as well squeeze all I can out of it.
What should I do? 10.25 to 1 piston?
Can i get a better CAM?
I'm not big on 4 strokes at all... i had an 85 350x that was pretty impressive, but I'm still not stuck on them.
