blake. what do you search for on ebay i put in something like "3.42 gm speedo" and I only got one hit

If I recall correctly, I just searched for "TH400 speedo gear".

It came back with a number of results, and even listed the gear ratio they were for, so I didn't even have to count any teeth. I just nabbed the one listed for 3.73, and I was in business.

Not sure what they'll have out there for your 200-4R...

And just fill in the blanks. Remember you will need to know the amount of Drive Teeth you have.
