While we are still on the cam damage issue,........ Did'nt someone say something about a "Mod" for the upper banjo bolt on the oil line that gives more oil to the top end? Is this just an additional part # from Honda? or is it a Mod to the existing bolt? Sorry if I missed the post on this, and Thanks for any info. on this.

Oil Bolt Mod

There are two different bolts for the upper end oil feed line. The lower bolt has a slightly larger hole than the upper bolt. Why Honda uses two different bolts I don't know but they do. So the mod is to replace the upper bolt with one of the lower ones. I didn't know that there was a difference and when I checked my bike I had them reversed. Opps. Oh well, no damage done. I found a larger holed bolt in the bolt box and swapped it in.

Thanks Steve! So I can just order a "bottom bolt" and swap out the existing "top bolt".........................Cool!

Was told by the service manager at the dealer the upper bolt is to retain oil pressure and keep from putting too much oil in the top end.
That said I also have not heard of problems from those that did the "Mod".

I have seen the upper bolt and lower drilled out to a larger size but I do not recommend that.

Now I have not used an aftermarket cam but at 15,000miles I did have to replace the stock cam and rockers because of scoring on the rocker faces and cam lobs. Once it starts you cannot stop it. Only reason I found it was a countershaft spline issue that was being replaced and saw the damage during tear down.

Supposedly the RS600 flattrack engine from HRC used a larger oil line and possibly different bajo bolts. The oil pump is supposed to move more volume as well. That info did not come from a reliable source, so take it with a big grain of salt. RS600 parts are like hen's teeth anyway.

Oil Flow

I don't know how much an over size oil feed line or banjo bolts will feed the top end but I do know the limiting factor is the oil feed holes in the cam that WILL limit the amount of oil flow. It's like a nozzle on a hose. I don't care how big the hose is, it's the hole in the nozzle that decides how much water will come through. And no, increasing the feed line and banjo bolts will not effect oil pressure. That is the oil pumps work.

My .02 but I may be wrong. Have been before.

i did the oil line bolt swap about 700 miles ago and the topend on my xr with 54,000 miles seems much quieter. you can drill the top bolt the same size as the bottom but i just bought a new bottom bolt from honda, i think it was around ten bucks. if you compare the hole size the bottom bolt looks to be a bout twice the size as the top.

That's It,............. I'm gonna do it. I'll call my friend (parts mgr. @ honda) and let him tell me I'm Stupid, yada-yada.......... and then perhaps order it online. The theory works for me.

XR's only temp dipstick & Magnetic drain plug

I have a used XR's only temp dipstick used red, and it does fog up on rainy days, also an unused engine oil drain plug magnetic also in red.

$20 shipped.

I installed a vecter computer that has a temp sensor. The drain plug was a wrong purchase, I thought I was buying the frame oil drain plug.

send me a pm, I take paypal. I'll send a picture if interested.

Thanks

yeah the stock air box is not water tight unless you add your own gasket or bead of silicone.
Sorry, no, I meant the intake tract that comes from the airbox. IF you managed to seal up the airbox, then you could get the intake height to just under the seat, but I think it'd be pretty difficult to seal that side panel and still have it be easily removable with the Dzus fasteners as it is OEM.
