I need both front cams and the followers or swingarms. I checked with the local dealer and they want $700. Its an 09CR. Does anyone have a way to check part stock so I could call a dealer that might have these parts sitting on a shelf somewhere? I put up a parts wanted thread but no luck there. | ||

New Castle HD has a online parts stock. They give 15-20% off if you order online too. | ||

Surdyke also has an online dept and prices are usually really good. | ||

These are expensive parts and they will become even more expensive as spares start to dwindle. These parts do not normally fail. They will usually last the entire length of the engine. Just by your parts request I know you have an oiling issue. This is not uncommon, but it needs to be fixed before you replace those parts. Further to this issue, you need to disassemble that assembly completely, as I am also pretty certain you have trashed the cam bearing supports as well. I suggest you get on eBay and buy a set of heads off a wrecked bike. It will be a lot less expensive. What I have found that causes this fault are internal oil leaks inside the engine. oil is supplied via a head bolt passage from the case to the head. This bolt hole in the head has a hole cross drilled to an intersecting hole in the cam bearing block on the valve cover deck. There are no seals at all those intersection points along the way. A leak anywhere on that path will deprive the valve train of lubrication. | ||

These faults are almost always assembly errors where speed took precedence over due diligence. Usually the leaks were due to burrs or surface imperfections at the joint interface, which left small gaps that allowed the pressurized oil supply to vent and not get delivered where it was needed. These are very difficult to test for without pressurizing the oil gallery artificially. I have seen this now on three separate engines. These were FACTORY errors, not shop mechanics, at least on my examples. On one of the engines, which exhibited this fault, not only did the followers, lobes and bearings suffer damage, upon disassembly the drive pin at the hub of the exhaust cam drive gear had been misaligned with the "T" slot of the exhaust cam and was driven on regardless of the misalignment, perhaps with a hammer. This caused the slot to be chipped out destroying correct cam timing. This caused exhaust valve retard by about 5 cam degrees. These engines are not the easiest motors to work on. There is a lot going on in some very small spaces. I am concerned enough about this that I will build an external electric oil pump and tap into the gallery somewhere, just to validate correct oiling. I'm not sure where these engines were assembled. I have heard that they were delivered to Buell already assembled, so I suspect they were assembled by Rotax. Perhaps Court would know the answer, he seems to know these things. In any case, I have not been impressed with the quality control. It would be interesting to know how many engines had to be replaced under warranty. Perhaps that is why EBR is now doing the engine assembly themselves. | ||

I'm not impressed by the build quality if what you say is true. | ||

Steve try the oil pressure sender port... | ||
| Skntpig |
? Oil pressure sender port? | ||
| Skntpig |
Any insight and assistance here will be appreciated. I'm not ready to pull the trigger before I get more info. It looks like this is the only place I'm going to find any info. I'm not a motor builder but have done my share of top ends. I haven't had these heads apart to understand what is really going on. | ||

Sknt, Steve was talking about applying pressurized oil to the engine to check assembley and where to put it in, the pressure switch sits on the crank end I presume that the pump will fill the galleries and pressurize them. hence use the oil pressure sender port. | ||

I bought 2 complete used heads for parts. I think I only used a rear cam and the block holder, so I should have all the other parts you need. STill in the market? | ||

Recently, my 1125r sits in the garage collecting dust due to this issue: http://www.badweatherbikers.com/buell/messages/290 431/636663.html The “balancing gear” has no “load” on it and is just supposed to free wheel around the supporting shaft…I suspect a heat treatment spec was not followed or is incorrect for the application. (check yours as the cam chain makes an efficient escalator…taking bits of case hardened steel up to the cams). (Message edited by nuts4mc on July 10, 2014) | ||

YES I still need cams and followers. Please PM me. | ||

PM responded. Did not get your pics. I am interested. | ||

Thanks to Sprintst I have cams on the way. |
