My flakey rockers and my 916

Well Ken, "Maryland998", came over and we checked all valve adjustments writing down everything and there were a fair share of adjustments to be made. So we pulled cams. Total of 9 definite rockers that need to be replaced most of them bad. A couple with the chrome gone on the contact area. Two other rockers are showing the signs of having problems soon. We inspected the cams and they are fine. Still trying to figure out how 14 track days and no other riding cause 11 rockers to go bad. I asked last offseason when it was serviced by a well respected Ducati mechanic "were there any flakey rockers?". Shook his head no. So somehow in 14 track days I have all these bad rockers even though I've seen no chrome flakes and I change my oil every 3-4 track days(yeah the expensive oil that's supposed to help prevent this), let it warm up, etc.

Anyway my local Ducati dealer has rockers, not sure how many, and they're $46 I believe. I do NOT want to get Megacycle rockers as I plan on selling the bike as soon as it's back together as I planned to do before doing before I took it apart for maintenance. How much are MBP rockers and do they take OEM ones as core and how much?

I saw "blade625ct" mention these one time. Anyone have experience?

This has also definitely made me convinced to sell my 916 and 996 when this is done and go 998 or 999 where this isn't as much a problem.

And I have even considered just parting out the 916 instead as $500 in rockers is not cheap. So I start thinking how much the bike is worth and how much I can part this and that out for.

Any advice?

I could never bring myself to part out a good 916. Pain in the azz to fix? Yep...but they're gorgeous bikes and the "new" owner is gonna be easier to find and more willing to part with his/her cash with a well maintained machine. My 2 cents. :)

If it was mine, and I was going to sell, I'd put the factory $46 rockers in and be done with it.

I have to say this exact reason is why I was looking for a 998, something non-DesmoQuatro, last summer...
(and in the process discovered the 1098...)

I wouldn't part out the bike... even if you could make an extra few dollars it is a lot of time dismantling, advertising, packing, etc.

Just opinions, I wish you the best Sam,

When I spoke to Guy last month he was charging $50 for a rocker and yes he needs yours sent to him. I'm not sure if he treats them as cores or actually reworks your rockers. So they are the same price as OEM rockers but apparently do not have a documented failure that I'm aware of. If you have time, it makes sense and it would add value to the bike if the next owner knows what he is buying.

I'm with the others, don't part the ole girl out just yet it has to be worth more as a whole than in parts.

for the same price, well $50 each, I'd DEFINITELY put the MBP replated rockers in. They do take old rockers as core, provided they are not mangled. Flaked chrome is fine, of course. This could be a selling point for you at the same time.

Umm,
Makes you think whether your dealer actually inspected the rockers, eh?
However, 14 track days is a lot of pounding outside of the service inspection. I would think it plausible for the rockers to go south in 14 track days. You know, after every corner, balls to the wall, hitting the rev limiter.

What about that link I mentioned?

"Electraeon Super Rockers have been developed to provide the complete solution to the rocker arm problem. Super Rockers are precision machined from a solid block of tool steel. The steel is hardened through the entire thickness of the part. This construction method provides excellent wear and impact resistance without the need for hard chrome plating.

Drop in replacement for the OEM parts.

Exceptional durability.

Superior wear resistance.

Suitable for use with aggressive cam shaft geometries and high engine rotation speeds.

No chrome plating. The entire part is hardened all the way through."

Rev limiter? Is there a rev limiter on like Ultimap or other chips like that? I never felt it this offseason. I would think on the 916 I would have at 9500k or so and a few times can remember looking at the tach down the front straight and it was over that by 1K at least. Only for a few seconds then a quick shift by me.

Keep the girl happy.

To all that read this post. Sam is now dealing with alot of angst. One of his Italian mistresses is being a B**CH. She wants him to spend some of his hard earned money on her and not that other petite girl from northern Italy. She did get a little bit of a worried look on her as he mentioned that he might have to cut her up. And sell her to the highest bidders.
Sam this is an obvious desperate cry for attention. Keep your pimp hand strong. I will come back down when I get back from Florida and help you get her back in line. Ken.

The problem is in my mind is that I'm not really loving "the ole girl" anyway. Never really have as I've owned it for 2 years and it's not my first Ducati and I've had a 996 as well. So it's not like "I have to make her good again".

Since it's a total track bike meaning no speedo, no title, track bodiwork not in perfect condition, the cost I could get for it is not what you may think.

I don't wanna spend more time or money on the bike. I'm tired of it. I wanna sell as is.

It seems the MBP rockers are probably the best "deal". Probably last longer than the OEM ones and are only $4 more. However I need to provide MBP my rockers to make the ones I get out of. I had Ken "Maryland998" helping me pull the openers but the closers to send to MBP are a little tougher.

Anyway since I'm doing 11 and then selling the bike I'm wondering if it pays off the just replace the additional 5. That would mean $800 in rockers.

I would, You'll find a buyer that would be willing to pay a little more.

I talked to Guy (MBP) and my rockers are on the way there to replace his stock and he is getting a few more full batches in soon and one has my name on it!

I am doing them all for $800 since I am also doing MBP collets, there is no messing around. THe 'inert gas furnace stress relieving' is important and MBP claims ducati doesn't do this step. You get a better chance for equal parts every time otherwise you cannot gauge residual stress in each rocker you receive.

In life, the smaller company will always push the quality envelope to the best limit possible. Their life depends on it. It also doesn't really cost any different than stock!

Sam, they may well be great products - cetainly LOOK nice, but at $150/each, you're looking at 3 times the price of an MBP replated rocker, for perhaps little or no practical benefit - and they are frankly somewhat of an unknown quantity at this stage, IMO (I'm not aware of anyone actually using them and confirming their reliability in this application). For example, does anyone know how much they WEIGH?

Oh, and there is a rev limiter on the FIM chip. It amy, or may not be set at the stock RPM, as it is adjustable.

Not sure about $300 more. REmember my bike is fully track with not much in terms of aftermarket goodies and not in since a track bike not great condition looks wise.

Ebay it. I sold two bikes on Ebay.

I'm guessing the mechanic didn't pull the cams at the last service.

IMHO I don't think they were. I mean some of the rockers were very bad. We're not talking just the start of flaking. We're talking the whole contact patch gone. And I didn't see any chrome in my screen when I changed oil.

I think that many techs change the opener shims and leave the closers since they take much longer. This way they can avoid pulling the cams as well if they are clever. If they can get it close to OEM tollerance, they close her up. how many owners open their top ends to check the work done? There is no way they pulled your cams last time round! It appears that you are a victim here.

I hope I'm wrong really since there are so many owners spending big money to have it done properly. I will probably spend twenty hours on mine since it is my first time so a good tech could probably do it in six to eight. Perhaps less if some of the shims don't need changing.

I mean I'm a fast beginner on track days so it's not like I'm pushing the bike nearly what a good rider would. Imagine if someone was racing it. I'm guessing hopefully that maybe the the current rockers I have that are bad but not too bad happened this year and same with the ones that will go soon. However some I just find hard to believe there weren't some signs last maintenance. O well.
