Shipped my camshafts out to Webcamshafts!

Called webcamshafts and confirmed that 09/10 has 109/101 cam centerlines. 10'-20' has 105/105. Sounds like they offer military discount on their services so im going this route. Attached is the stock cam cards for both. -Brandon V

Oh shit I missed that timing card! Good catch! I punched the info into cam cruncher and this is what it looks like. -Brandon

I think there is more to this. Now im no expert but, 4 Degrees of timing difference on intake and exhaust completely changes the power band and valve overlap. I fully suspect that hardwelding and adding additional duration or valve lift to the 101/109 cams could result in negligible results. You...

Post Weekend Update: Spoke with the man the myth and the legend this weekend, Tim Nash. Tim confirmed that there were in fact two cam profiles that came from Yamaha and unless you dismantle down to the flywheel its incredibly difficult to determine which one you might have. For those that have...

Oh I should mention, when ordering from yamaha directly Tim had mixed results on Cam centerline profiles.

A forum member reached out to me to inform me that Tim Nash discovered differences in cam profiles over a few years. Apparently the 09/10 models shipped with cams that had a centerline of 101/109 whereas all the late models shipped with 105/105. This resulted in a 10hp difference between those...

Wow hard pass. Heres my update: I was able to confirm that there are three intake camshaft assemblies in Japan at the moment of writing this. 3 Exhaust camshaft assemblies of one part number. The other is backordered. With military discount applied (thanks partzilla!) Im looking at $1800 with...

Was that the Grind 933 from Webcamshafts? Without looking at the Stock Cams specs I cant really tell where the increase is or what part of the power band is being robbed. I like low end torque and dont really care for RPMs or Upper HP. I just got a call back and I can source 2 new intake cams...

Im hoping that by documenting my journey here it could make this job less daunting for others to try it.

Its tough to say. Yamaha was bewildered that they were worn that much. If the spec is 32.850 - 33.90 thats a small margin for error. With the service limit at 32.750 mm on all lobes. Mine coming in on average between 32.35 mm - 32.5mm we are talking 10ths of a millimeter off on a cold engine...

So cam upgrade is off the table. I was hesitant to even consider it in the first place. Considering im sticking with stock measurements should I spring for new cams if I can find them or get the existing ones hardwelded and resurfaced?

Max I have you down for the throttle body set. I will PM you and mark it as Pending!

Heres another picture of the exhaust and heres the fiberglass belly pan.

I also have a fiberglass unpainted underbelly pan and hardware from Exactrep. Looking to get $150 for it.

Update: I reached out to my local yamaha dealer/service center. Immediately got forwarded to the Master Tech with 40 years of service. We poured over the details together and got on a call with Yamaha themselves. Yamaha is impressed by the wear on my cams for the mileage and after showing them...

I will be posting up pictures later today. In an effort to pay for my camshafts to be resurfaced, I am posting up some parts I've acquired over the last few years. Buyer will be paying shipping, or local pickup in Wisconsin. Online payments will be posted via Paypal. $400 - 200 Width OEM Rear...

Update: READ THE SERVICE MANUAL! Seriously, the camshaft section is only a few pages long. Turns out that my cams are worn past the advisable service limit set by Yamaha. i.e. Lobes on a new camshaft will measure 32.825 - 32.900 mm. That is for both intake and exhaust cams. The service limit is...

Service interval called for 25k miles. Im at 32k so this has been long overdue.

Hello all, I began tearing into my Gen 2 for its overdue valve clearance job and I wanted to share my findings with the group. Overall this job requires a lot of patience, garage space and a wide variety of tools. I called around to my local yamaha shops and they charged in the ballpark of...
