dan williams Posted February 22, 2018 Report Share Posted February 22, 2018 Swapped out the reeds for carbon fiber and found one screw on the manifold was a T25 security screw. Wasn’t expecting that. Also noted was what seems like thread locking compound on idle adjust screw. Explains why it snapped off first time I tried to adjust it. Carb also looks different but not sure. Top of slide housing seems different and bottom of carb has serial number. Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 22, 2018 Author Report Share Posted February 22, 2018 Forgot to note this is a 2018 EVO 300. Quote Link to comment Share on other sites More sharing options...
reggie Posted February 22, 2018 Report Share Posted February 22, 2018 The best way I have found to deal with the idle screw is to undo it the same way as tapping new threads. Loosen one quarter to one half turn, turn back in one eighth to one quarter turn until it loosens up enough to turn out all the way. I usually put some 2 stroke oil on the threads before putting in a new quick adjust screw in. As for the reed block, there security screws are a pain, on the bright side no one has stolen your reed block.Some of the 2018 Evos also have security screws holding on the exhaust tip, maybe you should change those too.

petert Posted February 22, 2018 Report Share Posted February 22, 2018 A kit with all the bits for these and other security screws is available quite cheaply at Halfords Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 22, 2018 Author Report Share Posted February 22, 2018 Yeah T-25 security bit is needed to take the tower off a Keihin PWK28 so I had one. I take “no user servicable parts” as a challenge. Still this is beyond the usual for a trials bike. Not as bad as my wife’s CRF150f plugging the mixture adjust screw. But a harbinger of what’s to come. Quote Link to comment Share on other sites More sharing options...
goudrons Posted February 23, 2018 Report Share Posted February 23, 2018 It seems those screws are correct. The parts list describes 31.38010.000 x 3. M6x25 Screw t.c.c.e. and 007.11.031.00.00 x 1. M6x20 Screw (and shows it top left out of the four) For 125-250-300 Apart from the different heads, one is 5mm shorter?? The 200 just gets 4 x 31.38010.000.

scifi Posted February 23, 2018 Report Share Posted February 23, 2018 Isn't it that one hole is countersunk, and the other three are flush, for location purposes...? . Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 23, 2018 Author Report Share Posted February 23, 2018 Well if you put the manifold in any other orientation the carb won’t fit. Quote Link to comment Share on other sites More sharing options...
carlos Posted February 23, 2018 Report Share Posted February 23, 2018 Yep, bunch of stinkers, my 2017 Factory was the same. Do they really think your going to bring your bike back to the stealership because of a few screws? Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 25, 2018 Author Report Share Posted February 25, 2018 (edited) Just as an aside the stock reed cage is the same as an early 2000s KTM 65SX. I'm tempted to get a rubber manifold from the KTM to see if it fits. Edited February 7, 2021 by dan williams Quote Link to comment Share on other sites More sharing options...
