Picture attached (taken from the front of the bike) Waiting on a reply from TB parts but i figured I'd jump on here and get some opinions or see if anyone else has seen this. Im currently installing a TB 143 kit on a 2022 KLX 110 RL. The "IN" that would typically be printed on the intake side is printed as "NI". that is making me think it was mislabeled or printed on the wrong side, because if I put the "NI" at the top like it should be, it reads backwards but if i were to turn it to the bottom (the exhaust side) then it would read in the right direction. I dont want to install it backwards, hoping someone can help me make sense of this, either that or tell me that they agree with my assesment 😁

Thanks for the info @storminnorman07 Got her all back together, made sure the mark on the cam sprocket was lined up with the mark on the head (both at 9:00). Same with the flywheel, the T line is at 9:00 with the mark on the case. She wont fire. When trying to start, its coughing air out of the intake, rather than sucking air through the intake. I have the kit with the 26mm mikuni carb. Stock head.

Any suggestions are extremely appreciated! Wont be able to work on it again till the weekend.

When you lined up everything did you make sure the cam chain was loaded (tensioner removed and pushing in on chain guide with finger to take up slack)? If not, you will be off by 1 or 2 teeth and your timing will cause what you are describing.

Wow, no i did not think of that.. the tensioner was removed, set the timing, reinstalled the tensioner and went from there. So you're saying that I need to set the timing while applying tension to the timing chain with my finger? That's crazy because I didn't see people do that in any of the countless videos I watched on KLX110 big bore installs. I will have to give that a try this weekend I really appreciate the advice!

V2 head solved the issue. Stock head just didnt like it i guess. Might have damaged a valve or something. Installed the v2 head with the TBW0645 cam sprocket (for 2010 and up models) fired right up. Running good, nice power. fmf 4.1 on the way should open it up a little more compared to the stock pipe. The newer klx 110's have those decompression weights on the cam gear and that may have been complicating things, no clue honestly but we're all set now. Thanks everyone

Oh btw, the official response from tbparts was "NI, IN same difference" 🤷‍♂️ alrighty then
