    PIT BIKE Tuning info

    I get a lot of jetting questions at tboltusa.com for these lil 4 strokes three things that could be helpful First off the bike may not be running perfect due to other factors beside the carb and you should make a few checks before digging into the carb most common are Intake leak exhaust leak tight valves Second you cant really tune a bike sitting on a stand you gotta ride it Third these lil 4 strokes do not run pumper carbs so they will stumble off the bottom unless you run a little rich on the pilot Here is a tech email I often send out RUNNING CONDITION Please go through these steps: Oil your air filter: http://tboltusa.com/store/tech.php… Engine and Carb quick check list: http://tboltusa.com/store/tech.php… To Check Valve lash (Tappet adjustment): http://tboltusa.com/store/tech.php… Jetting guide: http://tboltusa.com/store/tech.php… Most of the time you can tune new bikes in with the needle and brass screw adjustments and not need to change jets Tims TB20 jetting tech: The 20mm ShengWay carb is relatively easy to tune right out of the box. It comes with the #89 main and a #35 pilot jet baseline setting: I use the #90 or #92 main jet, the #38 or #40 pilot jet, set the jet needle e-clip in the 3rd or 4th notch from the top, and the air screw at 1-1/2 to 1-3/4 turns OUT from seated. Make the necessary air screw adjustments IN to richen it a 1/4-turn at a time and see what the bike does. With some of the carbs, I've run it to within a 1/2-turn of being all the way IN to get rid of 98% of the off-idle hesitation. You might have to raise or lower the clip on the needle, depending upon your altitude, I'm at sea level. Also be advised that the above settings are for use with an aftermarket or bigger valved head, not the stock head. You might want to try the stock carb jetting first, due to the smaller stock head intake port.

    SSR 189

    I have tried a few of these EZ Clutch levers including MSR but this one has the best feel Often the clutch cable routing and lube situation is to blame https://tboltusa.com/store/ez-pull-position-clutch-lever-and-perch-p-8095.html

    SSR 189

    SSR189 is a Dirt bike . very cool , not quite a full size but way bigger and heavier than a Pit bike SSR125SR is an ENTRY LEVER Pit bike , great for mobbin the hood , back yards and trail riding but for under $1000 new what are you going to get ? I really like these three Pit bikes 140cc mid size Pit bikes Way better builds and good overall size / wieght https://tboltusa.com/store/pit-bikes-c-46.html
