Almost new RH50. Put on a Prima pipe, new rollers and new clutch spring. Put in a higher main jet and it ran ok for a half mile and was it was bogging coming up the driveway. I put the original jet back in and now it won't start.
I put in a new plug, which has spark, turns over fine, just won't get fire up.
What am I missing? thanks
changed jet now it won't start

I had the 90 in and that didn't seem to work very well so I went back to stock.
I'll do some tests on the stock jet to see what the plug looks like. I figured with altitude and colder weather this time of year, the 82 would be a good place to start.
Scooter store said they don't change the jetting with a Prima exhaust, jut run stock. Said 90 was way too big.
I wish there was a standard chart for jetting, altitude and bike mods to give you a good place to start.
Exhaust go up X, altitude go down Y, big bore kit go X, etc.
My KTM 125 was easy to jet compared to a scooter. Don't even have to remove the carb, spin it, take out plug in float bowl, install new jet. 5 min and you are good to go.
