I can wheely mine with the standard gearing, in 1st but it`s not easy. The last time I tried, I yanked so hard on the bars I wrenched my shoulder!!



Getting pattern sprockets to fit should be no problem. Going one down on the front is usually the easiest fix for regular use but if you want to do wheelies, I would strongly advise going up teeth on the back rather than down on the front. As a rule of thumb, 4 up on the back equals 1 down on the front but you also have the option of 3,2 or 1 teeth if you think a milder reduction in gearing would do the trick. You will probably need a longer chain to do this but it is worth it. By wheelying with a smaller front sprocket the extra torque you will be putting through the countershaft will most likely bugger the oil seal or worse still, snap the countershaft.

A smaller front sprocket than stock will probably eat the chain guides on the swingarm.

Sprockets are available for your bike in several configurations. But most of us here have desired higher final gearing, if anything. Not lower.

Fogive my pedantry here, but for the sake of accuracy, the ratio is actually about 2.5:1

The ratio is dependent on the difference in size between front and rear sprockets that the bike comes with. If it has a larger front sprockets and a smaller rear, so the rule of thumb would be nearer 1 down on the front = 2 up on the back but you`re quite right on a T-bird it`s nearer 2.5 than 4.

I found this great article about changing the gearing on a TBS, which comes with a gearing chart and some 'how to' pics. hope it helps.
