TE/TC /TX 2017 300 she's baack

Full engine rebuild bottom to top. chassis lube, added an AXP full coverage skid plate, removed my TMD with Obie link guard attached. adding battery powered (made in China) horn , my squeeze ball means hands off, the push button will be better.

ANd I just fired er off.....the pilot must be clogged.....typical from sitting for a month with our great fuel.

cleaned up main and pilot went for test ride FAIL.......pulled carbby completely apart discovered documented Mikuni TMX38 issue of pilot circuit seal distorted and and open to main circuit. Some believe that this is one of the main problems so many have had with their Mikuni Carbs on their Huskys and KTMS. JD Jetting has fix-it kit JDMK05 has new upgraded seals to install under the "jet Block" (or whatever that saddle thing is called)

Hopefully the newer seal has a "firmer" set to it. Doesn't look like something that is even normally accessed during typical maintenance so I wonder how it's getting deformed?

You can see that during manufacturing they use a dab of adhesive to keep it in place. Also it really appears to be shrunk as well as distorted, probably from fuel additives or drying out between rides, maybe the different pressures within the system push/suck it in that direction, into the pilot circuit. There can be many variables for cause. I'm just banking that this is why my machine ran like crap after fully rebuilding the engine.
