i use an angle grinder myself. (actually a cut off wheel) i don't like pushing a rivet through a roller, as it spreads out the ID of the roller.
cut the head off the rivet , and then near the back part of the chain where you want to remove links, cut the outer plate in half, and then take the front half of the link plate off. zero load on the chain link you are going to run. I'll actually be doing this tonight.

Take the number of rear sprocket and divide by number of front sprocket. That will tell you the ratio. 47 tooth divided by 13 tooth front means for every 3.6 turns of front sprocket the rear will turn once. The speedometer will be slightly off unless you go up on tire size. 244 Shinko 3/0s will actually run faster than the speedometer reads,and the bike will also be going faster in your case,if you can wind it up fast enough. Unless you live in south Florida,I doubt you will.
OOPS, I wasn't thinking. It is not a 47 tooth rear. Anyway,mine probably runs better than anyone else's out there the way I have it set up. It ain't bragging if it is fact! I do believe that pure gas with a little Marvel Mystery oil actually give it a boost you would not notice if it was a bigger displacement. All I can say is try it in a speed run on same road in the same conditions. Maybe chain slack,alignment,tire pressure,outside temp,chain lube, or a good batch of gasoline. Try it and see,it will not hurt anything,it even stops the sound like it is going to fly apart rattles when winding the shit out of it. I think we are talking about a 320 to 1 ratio,and if you think that will F it up,I believe it might prevent it if you are in extreme conditions,such as extreme heat (pavement) heat ,heat for whatever reason is like a snowball going down hill in snow covered field.

Oh yeah MC, that was my intent. Spreading the JOY,I could even see the smile on your face before I posted. Actually I give you much of the credit for the helo you provided me when I started on this journey. I took the DR 200 out last night for a spin after putting on a 40 dollar Amazon carbon fiber exhaust. I think they are all made in the same factory and are marketed under different brands. I could not believe the difference,and shed about 12lbs from that OEM piece of crap.Got a NIBBI pwk 32 carb to put on it,just had a little problem with the air box boot being old and not pliable. 1999 model. New brakes,front and rear,as well as wheel bearings,Shinko 244s. I could not believe just changing the exhaust would actually wake it up with stock carb.Waiting on a UNI filter and new engine flange Amazon! VROOM VRRRROOOOOM.
