    You said the mid and upper where comparable to a 165? that's crazy!

    John,
    I told you that once Kelly gets something he likes it tends to disappear into the black hole never to re-surface. :lol:

    Sorry you had so much trouble with the cable end popping off/out of the slide. We must have lucked out it was (knock on wood) quick and simple for us on my 08Cr. Great report Kelly I figured you could do a better job of reporting than than me :D. Look forward to your report with it on the 165. Word of caution....make sure you have it pointed where you want to go with the 165 at anything above say 1/2 throttle on! It is funny how much more power you get and with better control where you need it the most; low-mid. It's all different though at WFO on a 165 anyway. Again great report and take your time I've got new tires on the TC250 :D.

    the 04-08 CR125's are rockets stock. The Doma adds a bunch of mid but caps the top a little... Well until the APT and now it is like a run away train on top. Missile fast. Almost feels like it will rev itself to death. I did not get top get into the top a lot but there was a lot more there than before (makes me wonder if my main is off on my stock carb) and just screams to what feels like endless top end.

    thanks man, I really appreciate it. I thought it was odd i needed 13 clicks leaner than you but I guess that's the beauty of a single circuit one external adjustment carb :thumbsup:

    I have a big fat beautiful KTM200 Doma pipe for it too. I seriously thinking this setup. 165, Dome 200 pipe and APT is going to be over the top FAST.

    BTW I feel the carb makes enough of the difference i could gear it up a few teeth.

    My son just stopped by and I was telling him about the cable popping out on you. He actually installed mine as I read the instructions to him. He said make sure once you get the cable into the slide to hold up a little tension on the cable as you slide and position the small washer on top of the slide. He said he thinks it (small washer with hole) prevents it from popping back out. You have it figured out now of course but this may help Walt.

    Nice unbiased report. From john01's place to you and the difference between the two bikes, 13 clicks means you moved the metering rod .026" to dial it in. How much weight in brass is that worth?

    It does but it also does not index into anything so it can spin and align and release.

    Wow, 11 pages of posts I just read to get up to date. After riding yesterday with Kelly, and trying it out first hand, I figured I better check-in to read up a little more on it.

    I am not a "fine-tuner" by any means... I get my stuff to run ok, then just leave it. If something doesn't feel right, I always assume it's me, and don't even think about tinkering with a bike, so sometimes it is hard for me to notice changes. However, that being said, i did notice some changes on Kelly's bike with this carb.

    The absolute most noticable to me was the throttle response. It is WAY snappier, and WAY WAY more responsive.

    Second thing I noticed was I could ride his bike in a much lower RPM than before (meaning more power)

    The other thing I was diggin was it only took him 20-30 seconds to make an adjustment to the carb externally, without even getting off the bike. This gave me sufficient time to warm my hands on my PC pipe.

    I give this carb two mugs up! :cheers:

    Thanks John for sending it to Kelly. I just happened to get lucky to be able to try this carb out!

    You guys are welcome. I just wanted to make sure my butt-o-meter is still working after 53 years :D. I only know how it felt on my WB165. I really didn't think it would do too much for the power on a 125; glad it did. I did expect the better throttle response and snappier power. I'm a tinkier and keeping up with the Mikuni on my bike in VA this time a year was a pain in the old ... I'm glad you got some time with it and hope you get to see/feel it back to back with your WB165. Thanks for your input :cheers:.
