The bolts that hold the rear caliper together are a spesial that is from AJP. It can be sourced, I think, if your bike is a '02 and up with the rear caliper inside the swingarm like my '07, a glance indicates that it is a 8mm x 1.25 thread, 40mm in length, with a special 10mm washerhead hex. Appears a conventional 13mm hex has no clearance for turning. The only alt I can think of would be a LOW head allen cap screw for clearance. Can be had, just have to find it!

Cody Webb prefers the Dunlop as I understand, I have seen Geoff Arron attempt absolutely stupid stuff on a totally worn out practice Dunlop, and survive! Boggles the mind!!!!!

Shan, couldn't you have gotton the shot with the "over the bars" ?

Obviously he has more vacation money than you!

Did I mention the fact that if you change only one letter it would be GayGay!!!!!

In continuing thoughts of softening the controls on the bikes, I had just a bit of extra time to experiment this last weekend. Much of this comes from Dan's posts on improving the Beta clutches. On the Sherco clutch, my theory is this. In the old days of the '01,'03, and '05 bikes that I had, the clutches seemed near perfect. Starting with the '06 bike, some seemed to complain that the clutch seemed a bit too grabby. Mind you, they went to the medium length lever rather than the shortie during this period, in which there is a signifigant difference in the pull length to the sweet spot. More feddling brought me back to the heavier oils on the "07 to reduce grabbiness, yet what is left of my finger memory and such just simply inclines me to believe that they changed the clutch springs in progression, to be slightly heavier and quicker for the top riders. It is obviously quicker due to the lever, yet I think more is there than meets the eye. I had experimented with removal ov two springs on the wifey bike(125) long ago, yet it was just too light, yes you could ride it but it was soo light it left little tactile feedback. Just not right in my book. Trying this same brief experiment on the '07 was totally different. Even after reducing the total spring pressure by 33% there was still decent feel, yet things were off, had to adjust the release point back in a bit, and it was glass smooth in operation. I attribute this to the relief of stress on the seals and such, which actually nets what seems to be a gain of 40-50% in operational smoothness! Now the backyard testing, well it is smooth, could work well for most between 1 and 3 gears, still seems to have a good grip(pop) point at end of travel. I could adjust to this, speceally reduces finger fatigue. The 4th and 5th gear tests revealed signifigant slippage when popped! Mind you I am still on the thick oil, not the ATF! That experiment will wait, as my oil is fresh. However I do know from experience, a total revv and pop in the upper gears may give you some slippage in the stock setup. Just seems to take a moment to squeze the oil out from between the plates. None of the Experts would want any part of this I think, Just us old farts and such! Even in this light configuration I could not slip the clutch enough in a normal trial to damage it, no less what the pro's put them through in their useage. ps- We had a ride this past weekend after our summer break. A dislocated rib left me nothing but honey doos, so I had to stay home and play in the back yard! Yes, it still hurts!

Tell us who it is! Last I heard, the factory exchange units were still expensive, like $600 or more?

I'm soo glad it was not from the other direction!!!!!!!!!!!!!

Dabster is correct, however, if anything in those years people complained about the shocks being too slow and heavily dampened. You just have to try it, may liven it up just a bit just in the right direction?

I have to go withthe Ringmaster on this one! None of that points crap Craig, just last man standing in Vegas! Good job Vern, you make us O'50's proud! Craig is still a young punk! Yet he does get better with beer!

The Sherco will have better torque, better for most riders in my thinking. Also typically require less major maintenance.

Does this mean that he will move up next year? Seems he certainly has the talent! Leaving Alexz to deal with the Juniors?

You must understand that Zippy found a kitchen drawer lining material in black with skulls to cover his plastics! Oh well? Maybe that suff will protect the frame? I did allways like the one with flowers?

Dan has done mods on the beta clutches and reports good results., including the removel of two (opposing) springs on the pressure plate. As they are very similar and the same principals apply, this could work for you, yet I have never done it on a big bike, only a youth's 125. It was sweet! But if the engine power is allowing any excess slippage it will burn the plates, so beware! Another thing that comes to mind, you could even run 20-50 oil on the box to slow the grabbiness of the clutch. Once again, never done it in a Sherco, I just run what I brung for the most part, yet I have run the ATF(light oils), and it does seem to make the clutch a bit too snappy for me. All per your taste I think!

BS, recall this?

I spoke to a guy called Ian, who was very helpful. I sent my old spring to him for exact measurement and he set about making a new one. My old spring was away for five days, returned to me via recorded delivery. Exactly two weeks later the new one arrived, powder coated in yellow. It's now been refitted and I have been trying the bike out - what a difference! The bike doesn't sit down at the back as much and the whole thing seems alot smoother and controlled. (This is compared to winding the spring up with the bottom adjustment ring). Although, I haven't had chance to really put the bike through its paces - its a case of so far so good ! If any of you are thinking of uprating your spring, give Ian a ring, he very helpful and the product is top class ! I hope this is of use. RR 65 quid?

Try uk-motoplat.com, even for a ducati setup.

Whats the matter Chad, they won't help you on the gasser forum? The way prices have gone the last few years, that $30 part may be $100 !!!!!! Does not matter, has to be done, just do it! And be glad ti's not the motor!

I seem to recall hearing that the heavy springs for the older shocks were hard to find now. I think the diameter is different than the newer versions. You may have to scrounge to find one. Reguardless, if you are a really big boy, well over 200lbs , you are still best advised to get a heavy spring reguardless of the shocker. May just change your entire perception of the bikes handling qualities. I say this still knowing several LARGE experts on the stockers with no problems. At least up to the point where I set them a few sections with some big jump offs!

Sounds as though it still has its damping oil and its nitrogen charge, so you may be lucky!

Cubby, you need to leave some space for expansion of the coolant. Excess will be spent!

I figured Zippy was in on that! Specially in south texas, with only little trees, you just park the trailer, feed the deer for a bit beforehand. They just walk up next to you! On openening weekend all the guys show up. Whiskey, pickeled pigs feet, box of cigars and a case of sardines is the usual breakfast fare! Steak and potatoes are usually burnt about dark! Never shoot anything but beer bottles, which scares the deer away!

That's just what you need Glenn! Did you see that stance on a young Andy in the background! Reminds him of his youth! I think Slapshot was in the background taking a pee!

Maybe someone will post! Good job Laura!

There is a fix for that when everyone does their own ITSA events and no one shows to theirs!

Krylon rust tough or industrial, semi- flat black! It will make you a rattle can artist once dry overnight, just rub a bit for near perfect match!
