what the advantages to tuning the spring weight? Heavier = more pressure? Stronger engagement?

Basically the more power you make the more likely the clutch is going to slip. Stiffer springs will make it less likely to slip. The trade off is the stiffer the spring, the harder it is to pull in the clutch lever. Chris having 73 pound springs on his drag bike, he doesn't use the clutch that much. On a trail/dune bike I think the 73 pounders would wear your hand out in a short time of riding.

Also on a drag bike being able to adjust the springs will you adjust your power to the track surface. Some are very hard others are sandy.

I use Barnett hd banshee springs with ebc zilla clutch plates. It is a tight fit getting the springs in but they do fit. It is surprisingly easy to pull. I'm hard on clutches and often slip the clutch to get RPM's up when climbing a dune. So far they are holding but I probably am burning thru plates faster than normal dirt or mx riding. So far I'm happy.

How are you liking that Barnett clutch?

I've got a quick question re: a Hinson basket:

Do these require any additional parts when installing?  Or, does the basket just replace the stock basket?

I ask because I have one I took out of a spare motor I have and will be putting it in my (now) running motor this weekend.  The stack of pieces I have with it from pulling out of the other motor seems to have a spare washer with it.  When looking at the exploded view in the manual (page 3-49 of the 88-92 manual) I've got two of the washers that go between the basket and the "Clutch Sleeve Hub"  It could just be a spare from another stock clutch I sold however, the weird thing is that the back of the "Clutch sleeve Hub" where the washer touches has a worn in mark of a 4 sided semi-star shaped thing.  I can't find a washer with these parts that looks like that, though and it's obviously not shown in the exploded view.

Will running a Toomey hd spring be any harder on a transmission than a stock, seeing as how it probably doesn't allow any slippage at all? Just curious if there is any relation between tranny life & clutch slippage.
