ECR role call - 9/22 & 9/23

[milesmiles]

I'm going saturday 9/22 and so is my friend that went last time. Post up! (also, a MOD that knows how to set up a spreadsheet..could you?)thanks!

[DarcShadow]

Ok, I setup a spreadsheet.

Looks like I'm scheduled to work Saturday, ride Sunday.

Edit: Registered for Sunday. Had one coupon code left.

[milesmiles]

Well that sucks Rhino

For me it's going to depend on when I get my bike back, the up and running.

[milesmiles]

Is it seriously going to be that long?!?!?!?!?

[fixxervi6]

Is it seriously going to be that long?!?!?!?!?

I MIGHT have it back by this weekend and then I have to finish putting it together. When I dropped it off it wasn't a whole bike.

If i don't get it back by this weekend that puts me out to next weekend which gives me 0 time to get used to the changes to the bike.

And in terms of assembly effort I have a KX100 to assemble, and I have a 250 frame with all of its parts all over the garage too so I gotta get all that done so I have more than just standing room in the garage.

[shilka99]

I'm scheduled to ride one day and teach the other (just dont know which). I'll be teaching class also but it could be level 1 or 2.

[milesmiles]

Hopefully lvl 2, i don't really know that track at all

[DarcShadow]

Eh, it's not that hard, hammer on the gas, stomp on the brake, make two 90 degree turns and then repeat. ha!

What better place to get use to changes than the safe confines of a track?

Safer to get used to GP shift on the street than on the track, if I blow a shift comig up to a stop light it's no big deal. If I blow a shift comig into a turn with the ass end all lose turning 14K rpm then shift the wrong way it could be very very bad.

[DarcShadow]

So just shift at 7K like you normally would. lol just teasin.

[milesmiles]

where's my spreadsheet!

What, you got a Bazzaz, a GP shift, and no slipper clutch?

Shame on you.

[milesmiles]

That model has a slipper

[DarcShadow]

where's my spreadsheet!

I don't know, where did you put it? My spreadsheet is here on my desktop. It's pretty cool, it tracks location of RIOs, VMCs, VETS, RETS, and general status of them all.

That model has a slipper

Well hell, if that's the case you've got nothing to worry about by blowing a shift.

[milesmiles]

i need the spreadsheet for this thread so we can keep tabs on who's goin!

[DarcShadow]

Oh, well you should of said so in the first place.

[fixxervi6]

Your slipper logic is flawed. Even a perfectly executed rev matched blip won't save you.

[DarcShadow]

How so? I thought the main point of the slipper clutch was to let you downshift with out worry of over reving.

[fixxervi6]

you and I both know you don't believe that.

Over reving and destorying valves was a problem wtih 4 strokes being introduced to 2 stroke racing, look it up. Slippers in 4's helped with two problems, and without slippers the 4 strokes were not able to compete. -- according to those on here that fear technology, that would be just because those racers that climbed onto the 4 strokes form their 2 strokes were just lazy --

A slipper doesn't free wheel, it "slips", so no, you can't be at red line and just start dumping gears, common sense will tell you what that will do.

If your close, some slipping will help protect from an over rev, if your at rev limit and you start dumping gears your going to over rev slipper clutch or no slipper cluch.

Miles, put me down as a maybe in that "spreadsheet", saturday

[fixxervi6]

Wikipedia:
"They are designed to partially disengage or "slip" when the rear wheel tries to drive the engine faster than it would run under its own power. The engine braking forces in conventional clutches will normally be transmitted back along the drive chain causing the rear wheel to hop, chatter or lose traction. This is especially noted on larger displacement four-stroke engines, which have greater engine braking than their two-stroke or smaller displacement counterparts. Slipper clutches eliminate this extra loading on the rear suspension giving riders a more predictable ride and minimize the risk of over-reving the engine during downshifts"

Sigma:

“…..Back in the mists of time (well, 1998) when we were cooking up our Ducati Supermono's debut we were trying to find a way to both make the bike easy to ride quick and, especially as it was my pride and joy, keep it reliable and in one piece. We had decided to use 250 riders, these guys like to arrive at corners, mash the gearbox down three gears and power out of the curve, with their two strokes having no engine breaking and virtually immune to mechanical damage overrevving this style is very effective A four-stroke single, even a desmo, is not going to appreciate such behaviour for long. The engine, valves and bearings are going to be hammered by the sudden overrevving (the rev limiter doesn't work when the rear wheel is turning over the engine!) and the rear wheel is going to try to lock up, the rear suspension is going to get bounced around too, destroying all pretence of maintaining grip.
Racing is about far more than power; as the MotoGP warriors are discovering right now, well controlled high corner entry speeds are just as important to a quick lap as sheer grunt.
We fitted a Slipper clutch; it gave us a real advantage, our riders could ride the bike exactly as they wanted, it let the bikes suspension work better coming into and through corners and also let the motor take the abuses of race track use without the constant threat of overrevving. As a result we picked up victories at both Daytona and Donington, first time out…..”

STM:

“What other benefits will I get from my slipper clutch?
Your slipper clutch works anytime the rear wheel tries to overcome the engine braking, you can adjust it to work sooner or later. On its standard settings, if you bang it down one gear too many, it should declutch automatically, helping you stop the crank being revved up past its rev limiter, helping keep your engine in one piece!”

“In addition to increasing riding benefits, STM slipper clutch systems prevent engine over-revving. Reducing engine over-rev preserves the function of engine ...”

Ehow:
"Why Do Motorcycles Need Slipper Clutches?
Over-revving a motorcycle engine, or changing to a low gear whilst traveling too fast, can damage the transmission and cause the rear wheel to hop and lose traction. This is a result of the rear wheel of the motorcycle moving faster than the engine normally operates, thus forcing the engine to rotate faster and cope with greater forces than it was designed for."

Suter:
"less stress while the risk of of over-revving the engine during downshifts is minimized:

Motorcycle-glossary.com:
"..Slipper clutches eliminate this extra loading on the rear suspension giving riders a more predictable ride and minimize the risk of over-revving the engine during downshifts...."

Answerbag.com
"Less Over-Revving
Motorcycle riders who tackle a corner in high speed and then suddenly reduce the throttle can often find their engine momentarily over-revving. A slip clutch can minimize or even prevent over-revving because of the partial disengagement of the transmission."

MCGmotorcycles.com
"A slipper clutch can minimize the risk of over-revving the engine during downshifts"

Personal experience:
I've had my bike pushed hard in the rev limiter range and the clutch has slipped on downsifts and the needle didn't jump up into the "oh shit" rpm range

No, the slippers sole purpose is not to prevent over reving, it fixed two problems with the 4 stroke, over reving was one of them.

[DarcShadow]

So based on all that it sounds like my assumption was somewhat correct, slipper clutches can stop you from over reving. So back to my original statement, there's no reason not to take your bike out to the track.

(again, just teasing)
