Things are not going my way. 180km into break in I spotted 2 small holes on the cylinder. I have spoken to the company I bought the kit from and they will contact Athena for assistance. Hopefully this ends well..

What do you think? I've now fitted a 310 main jet and she's still a bit down on power. It felt better than the 290 for sure. Now I'm thinking about buying a couple of extra jets, 320-350.
Is this even possible? I've not spoken to anyone running higher than 280. -
If using a TM28 carb then need a 300 main jet with a 27.5 idle jet. Main jets go up to 430. Put clip in the bottom groove on needle.

@2stroketerry I'm running 310 now and it's certainly not optimal. Idle is 35 now, definitely too big.
-
In reality, what would cause the bike not to start on the first or second spin on the starter. Is it just down to the pilot jet and fuel/Air mix?
Obviously a good battery and fresh electric components will make things easier but I got that covered.I've read in the Haynes that there is supposed to be a starter jet in the later carbs? Much of what that books says makes no sense...

I run the autolube on my dt125r bottom end with wr200 top end. I just adjusted it to suit the larger capacity. I've run it for years. Autolube is brilliant
-
@louis-james hows that thing to start?
-
First kick 99% of the time
-
@louis-james you run the 28mm carb? The flat one?
-
I used to, I had the tmx30 for a while, now a tm34ss
-
@louis-james you ran the 28 with the wr200?
-
No, I had the 30 when it was still a 125. Lid was cut off the air box the the 28mm btw
-
@louis-james alright
-
@irongamer727 recommend getting a decent reed block on there. Many can be modified to fit
-
@louis-james naah at the moment I simply want her to run good, start easy and stay that way.
-
As I suspected my pilot jet to be too big (size 35) I ordered a smaller 25. But the bike literally ran like shit and the idle was very uncontrolled and the bike just sounded wrong!
Is the next step to order a larger?
I can without a drop in rpm turn the airscrew all the way in, no change really.That must be an indicator that it's to small right?
-
Yeb sounds like you need to up the idlejet in size.
