Aftermarket fuel mixture screw fitment?

[davisjj]

Does anyone know which, if any, of the aftermarket fuel mixture screws like either the Tusk or Works Connection ones below will work with the stock Keihn carb on my 2018 XR650L?  I have the carb off and I'd like to replace the stock fuel mixture screw while I have it on the bench so that the screw will be easier to get to when the carb is on the bike.

Unfortunately, neither will fit the XR650L.  I have been looking also but have not found one yet,

Can't you just order a Honda part for an older bike, like before 2000?

[davisjj]

Yes, I could, but the stock screw is deeply recessed and really hard to get to when the carb is on the bike.  The aftermarket ones I've seen are longer and have a large knob that extends below the carb body and are a lot easier to get to.  Unfortunately it looks like neither of the ones I've found so far will fit.

I get that you need to swap out the current mixture screw.  The old ones stuck out far enough to turn with your fingers.  I can reach in from either side and turn mine, which is the original for my 2001.

Scott's right , the earlier years didn't have the recessed fuel screw.    Any of the aftermarket fuel screws for a Honda will fit , BUT most of them are aluminum and the nice point on the end corrodes away , the originals are brass for a reason , find a brass screw.

Sure wish I could.  No luck so far.

braze a L shaped rod to the end of the screw

I just put a dyno jet kit in my 2018 and used their tool to set it.  2.5 turns out and it runs great.
