I'm doing the sprag on my 96 Tiger. I am trying to understand the different sprags.

Here are the questions that I have been pondering:

I am a little unclear as the the difference between the different sprags. Assuming I have the 51t sprag, is it worth it to switch to the 53t sprag? Is the 53t sprag actually heavier than the 51t, or are all the sprags heavier now than they were in the 90s? (I know you have to switch the idler gear, also if you change the gearing.)

Is it necessary to machine the case if you have a later crankcase with no access cover? Has anybody "machined" the case themselves without the Triumph tool?

I really appreciate the help.

If it took 11 years for the part to fail, then perhaps the 53t sprag is not worth it. Although, gears should always be replaced as pairs. How long are you keeping the bike?

I plan to ride it a couple of years, but will be going on trips on it. I have been thinking it may not be worth the upgrade, but is the 53t sprag an upgrade over the 51t?

Thanks again for the help
