I ordered one of those for my VM26, but I am still waiting for it's arrival. I can definitely let you know for sure once it comes in.

Good discussion though because I want to get this right.

Well, the nice thing about sprockets is, they aren't overly expensive or difficult to change, especially going down in tooth count. Just try to figure out what gear ratio is ideal for your bike, you (weight etc), and it's use. For road use, I would try to gear it so that the revs in 5th gear sit right around where torque peak is at whatever MPH you want it to cruise at. This may make the bike over geared as far as top speed, and kill a bit of the acceleration, but I would rather not sit at redline to go 60mph. Plus, generally an engine is it's most efficient around it's peak torque RPM, because that is the point where VE and Intake velocity are at their highest, usually giving the most clean burn.

I think the 46 rear is a good starting point for what you want. It will put you right at 3.07. Then, if you want to go a little taller, try a 16 front, shorter then your 14 front. Going in either direction wouldn't require changing the chain links either as it's only a +1 or -1 front. That would give you a 2.88 and a 3.29 respectively. That's why I suggested the rear first.

I was wondering the same thing.

[da4design]

yep they fit the mikuni carb, and so much easier to adjust

So ordering the sprocket was a little more than I thought it would be. All the sellers were in Europe lol, finally found on on eBay, 45T. Can't wait to get it on and see the difference it makes.

[GeneralTso]

Well I got the Mikuni on and what a difference, bike runs so much better. Smoother acceleration, no break up what an improvement.

Next I have to swap out the sprockets and see how she does on the road with the better gearing for street use.

And yes I got rid of the choke cable, that little flipper on the carb is in perfect position to just reach under and adjust.

[pistolclass]

Totally agree the Mikuni upgrade was a great improvement on my hawk (110 pilot).

[GeneralTso]

I am loving this new carb!!

I kept the stock 15T front sprocket and changed to a 45T rear. I like it so far.

I just did a quick eBay search on these, and the shapes and sizes varied two or three times though the years....any idea which year's tank fit best for our application?

Not a clue; it's only a guess. The ultimate scenario would be to find a friend with an XR200 and borrow his tank for fitment testing.
