jet

I have a predator 212cc. I milled the head .050 and have a mod 2 cam, 8 degree key,140 emulsion and 18lbs springs and billet flywheel, bored out carb to match the stock butterfly. Currently I have a 36 jet should I get a bigger one and what kind of fuel should I run with all this.

Ok so it would be really cool if WE could come up with a chart / Matrix for people to refer to when jetting their engine. Here is an example of one that i worked on for motorcycles, tell me what you think: GStwin.com Wiki - Rejetting I dont have enough experience with these little engines...

I just removed my carb and put a new jet in and when I put everything back together and went to start the bike up, the flywheel and fan wont spin now. I really don't understand what the problem is! If anyone could help me figure this out, that would be great.

hey there guys looking to sell my basically brand new Asusa mini bike. I have been away at college but the bike was stored in my basement, while being there it developed a little surface rust on header tube, and wheel spacers, nothing 30 seconds of steel wool couldnt solve. Bike was stored after...

I must say the kart was running fine with the stock carb setup, but as soon as I changed the jetand emulsion tube, the kart will stumble and hesitate at wide open throttle. I'm using the stock intake and exhaust, with 18lb valve springs, aluminum flywheel, and removed governor. Like I say the...

Sweet jet bike !

What size drill bit should I use to drill out the idle jet on a baja 2.8hp? also what size drill bit should I use to drill out the main jet? (I have a header and a custom air intake on the engine). :grind:

I just bought a “Mini Baja” with the 5.5hp engine. It wasn’t running, so I got a good deal on it. I took the carb off and cleaned it real good and got the engine running. The main jet was definitely clogged. Once warmed up it idles nicely, but needs the choke half on to accelerate or run at...

I sorta did this on purpose to see what would happen. My stock little Jiangdog Honda clone was left with just a skosh of nitro-pink in the tank and carb over the winter. I wanted to see what would degrade, if anything. It cranked up and started fine this year. However, when I open the choke all...

i have an old minibike with a clone motor on it and i want to bore out my jet but i have no idea how big to make it could someone tell me? thnks

I decided to make this a post on its own. Hard starting... when you change the air filter and or exhaust, the idle circuit does not create enough vacuum... the solution is to open the idle jet. Where is the idle jet? you ask? its under the throttle set screw... 1 - Take out the throttle...
