Carb needles

Been doing some jetting changes lately. Raising needle position and all the other tedious stuff, and now I want to try different needle shapes/sizes. Where do I go to find the needles I need? Will XR carb parts work in our carbs? I don't claim to be a carb expert, but I will stick with it until it's right, so any advice is welcome.

'83 XL600
101mm bore
10.5:1 JE piston
Reed valve blocked off
stock exhaust(wrapped)
Uni air filter(de-snorkled)

1988+ cam mod for the XL600R update

The valves on the new ( old ) E-bay head were leaking some so that is off to the machine shop. In the meantime I have learned a few things. The Hot Cam in combination with the 1989 cylinder head cover ( from E-bay again ) is just a straight forward bolt it up job. The only things different are the sprocket end camshaft bearing needs to be from a 1988 or later XR or XRL. Also the sprocket needs to be flipped around if keeping the original chain is desired.

I posted a series of these pictures of the cam installed in the old head sans valves over on the Call all XR600R!!! thread. The rockers and lobes seem to line up pretty well. On the two heads that I have the cam is located in the head with the two end dowels, there is between .025" and .030" axial play between the dowels with the Hot Cam. With the stock XL600 cam this play is around .040".


Left side intake



The idea that I prefer because it should cost less and retain the original cylinder head cover ( and manual decompressor ), is to do a slight mod on the Original XL600R to allow use of the later model stock camshafts.

All measurements of the cylinder head covers are the same and there are very only very minor differences in the castings. The only significant exception is where the left side intake rocker shaft area has been machined to allow the use of the larger rocker arm in the 1988+ cover.


1986 cylinder head cover left intake rocker shaft area not machined.




1989 cylinder head cover left intake rocker shaft area machined.




This machined out are allows for the use of different rocker arms on the left side of the 1988+ cylinder head covers. The rockers on the right side are the same configuration as the pre 1988 XL600R rocker arms. Even though I used a Hot Cam ( and 1989 cover ), it is my believe that by machining out this area and changing these two rocker arms (and the small helper arm on the intake rocker ), the stock 1988+ cams could be used with the original XL600 cover.

The two rocker arms that would need to added to the pre 1988 covers. This is from a 1989, I believe that the later years did not have the extra wide exhaust rocker.



The only issue I see with would be plugging the decompressor hole in the stock 88+ camshafts.


1989 intake rocker arm



1986 Intake rocker arm. Subtracting 23.98mm from 29.22mm is the amount of material that needs to be removed in the original cover ( 5.24mm ).



The base measurements of the exhaust rockers were the same at 23.95mm and 23.96mm. Just buy a 1988+ exhaust rocker arm and put it in. The small helper arm is the same, so no change needed on the exhaust side. On the Intake side a 1988+ small helper arm will need to be bought but that to will slip right in to the original XL600 cover.

One interesting note is that if you had a 1989 or later RFVC engine, I don't see why you couldn't take an old XL cover, machine it out, swap rockers and go with a manual decompressor. I don't know if anyone wants to do that but I thought I would mention it.

I just picked-up a nice '84,600R. In Canada it cost me two grand. New it was $2,300! Seems like a lot for a old bike, but the new bikes are beyond my cash flow. Great bike.

Use the tool that comes in the tool kit. It works perfect in that spot.

Use an extension, preferably a u joint, to get a little curve to it. Just make sure to reinstall the plug with your fingers to make sure it doesn't cross thread.

the right 18mil socket and a stub extension means no silly joint needed
