125-200cc Hot setup tips for 144 kit?

Hi all,

I put the 144 kit on the 125 and rode it the other weekend but didn't get enough good time on it to really get a good opinion on the 144. I got my lectron carb this week and hope to install it this weekend with the stock pipe and maybe FMF turbine core 2 silencer.

So just looking to see what everyones setup is with the 144 kit?

Thought about changing the gearing but not sure what to switch it to. Maybe try a 51 or 52 on the rear.

Thanks

09 Wr144, lectron, fmf Fatty, turbine core muffler, 51 rear. I've only put 8 hrs on the bike but it will take whatever I throw at it. Ended up on some very big hills this past week and the only limitations were the rider. Much more bottom than my 08 cr125. I like the cr's ignition way better so this might get swapped this winter. I think I still need to do a little fine tuning with the lectron as it is a bit rich but I'm having lots of fun riding it. Enjoy!!!

depending a bit on what you ride (track or trail) but I would say that a 52 is not an overkill

I am having a 165 and ride trail but in dry season I still do like the 52 teeth

in wet its a bit to much spinning around and will get back a teeth or 2

'10 wr144 with 36mm lectron, fmf fatty and stock silencer. 13-53 gearing. This gearing works great for me(mostly tight,steep single-track). The fatty felt like it gave it a broader spread of power with a bit more in the mid-range compared to the stock pipe which may have had a little more on top.The biggest improvement I made to this bike was the lectron, spending more time riding now instead of chasing jetting on the stock mik tmxx.
