Performance CDI Testing on a Maddog 50cc GY6 139QMB

[@IOGTKI]

Just got my 150cc. I love all your vids. Thanks for teaching the community. Ran today stock everything and at 325 lbs hit 50 easy. Lol

[@GhettoWrench]

@@IOGTKI nice and thanks a bunch

[@seanmayo206]

​@@GhettoWrenchhello sir . U mind telling what fuel pump u running? Is it rolling wrench? I just purchased one from eBay . It's for a utv. Low pressure but the outlets are like 5/16. I think it's a knockoff off for Honda Ruckus 50. I've got the rolling wrench 21mm pwk carb which is hard to figure out unless the electric fuel pump solves it. I did strap the gas tank to the seat an gravity fed it. It fired right up but give throttle an bogg but if get rpm up it trys to do better. I put 6.5 gram rollers in to see if helps an I've got the back tire off ground to test but the dam bogging. Get small jets in it . Needle set in middle. Any ideas?

[@GhettoWrench]

@seanmayo206 I have the rolling wrench pump on 1 bike but the carbole 2- 3.5 psi pump on the others. Is your floats sitting too high? Could you be flooding the carb?

[@IOGTKI]

@@GhettoWrench thank you. I love turning wrenches and love all your humor.

[@Smodlee]

I like the blue one out of all of them it seems to be the best/happy/medium

[@frednetherlands887]

Thank you.

[@MalleusSemperVictor]

Now we just need to know what is easier when replacing the crank: swapping oil gears or buying a different crankcase

[@GhettoWrench]

@@MalleusSemperVictor that's a good question. Ugh.

[@christophersherratt7299]

REMEMBER THAT IF YOUR CARB IS RUNNING FULLY OPEN AT YOUR 50MPH YOU WILL NEED TO JET UP FOR FASTER SPEED MORE SPEED MORE FUEL ⛽️

[@GhettoWrench]

@christophersherratt7299 ya I jetted all the way till it bogged and got slower then came back down 1 size.

[@thelagmeister]

Good stuff to know. I always stayed with the stock cdi. Did you ever try out the remote start/alarms? Thats what that plug on the left that loops back into itself is for.

[@GhettoWrench]

@thelagmeister oh man. I had no freaking idea what that loop was for. No I never messed with those

[@thelagmeister]

@@GhettoWrench They are very cool. the alarm plugs right in. The brain and speaker have adhesive on them. Wam bam. It's actually very loud and with the remote start you don't even need a key in the ignition while you ride. They sell for $14-$20. It's one of the best things you can put on your bikes

[@GhettoWrench]

@@thelagmeister oh dang. Like free!

[@hesperidesbell4643]

Hey brother haven’t seen ya post in a while. Hope all is well. I did some more digging with CDI stuff and found that fully programmable kits from like stage 6 can get very pricey very quick lol. Definitely gonna go the cheap route

[@GhettoWrench]

@hesperidesbell4643 thanks for checking. It's too hot in the garage so I been lazy and mostly mountain biking. And this! LOL kzbin.info/www/bejne/jWrTYpV5gch7d6Msi=Or0T7u8r74e0W2B2

[@SBATHORGOD]

Man… those cdi means how fast you get there in 48mph.. in’s seconds

[@Frietpan]

i tried the glixal.. it blew my fuse every time, so that went into the bin. btw they have 2, a orange like one and a red "racing" one.

[@GhettoWrench]

@@Frietpan LOL. Typical Glixal. I had no idea they had a red one.

[@AliSajad-t4q]

Hello, can I ask about the bike with a GY6 engine?

[@GhettoWrench]

@@AliSajad-t4q sure. The black one or red one?

[@hesperidesbell4643]

My dad gave me a CDI from his 150cc gy6 go-kart. Its got a little dial to advance or retard timing +10° or -10° I've been running 93 and it seems to run well (this is before BBK)

[@GhettoWrench]

@hesperidesbell4643 ya I saw those. I need to try one for sure.

[@seanmayo206]

Can someone explain the flywheel magnet? The trigger or whatever lines up with magnet an piston is at Top but the F an T confuse me

[@GhettoWrench]

@seanmayo206 the pickup sensor can be welded to that flywheel in any random place just so long as the when it passes under the pickup coil the bike is at TDC. It is actually 28 degrees before TDC but that is so the CDI can retard timing and give you an adjustment range. They should have mechanically put it at like 40 degrees BTDC to give us more advance range adjustment... but they didn't.

[@christophersherratt7299]

If I remember correctly he runs at 1200 % 1300 lot more power hope this helps you

[@seanmayo206]

I've got a adjustable naraku CDI. This shit is so hard to learn. Maybe it isnt

[@GhettoWrench]

@@seanmayo206 yikes. I have not tried one of those yet. But you can only advance to the mechanical advance limit of the flywheel. I measured my 50 flywheel advance at 29 degrees. So you can't get more than that. I would just set it to FULL advance

[@sire-1213]

Side note... Do you think EFI kits are worth buying

[@GhettoWrench]

@sire-1213 No idea. I would love to try that rolling wrench one. It has to be better right? But $$$

[@seanmayo206]

I got a Kawasaki mule electric fuel pump on the 50. Supposed to be low pressure. It's hooked to a rolling wrench pwk 21mm from China.

[@GhettoWrench]

@seanmayo206 worth a shot.

[@christophersherratt7299]

I THINK HE GOT TO 12.5 HP

[@GhettoWrench]

@christophersherratt7299 wow!

[@mrhermitoable]

I left a comment earlier but i guess youtube deleted it because it had a link... lol I know you are in florida too, if you are around the Gainesville area or close enough and you feel like doing one more test, i have the one from rolling wrench that is $150, i always wondered if it actually did much and if i had made a mistake by not getting the ncy one. I guess i wont put the link again but if you go to the rollingwrenchdenver dot com and search "A/C CDI Coil Combo 150cc QMJ157/49cc QMB139 (Plug & Play)" I have that one.

[@GhettoWrench]

@mrhermitoable ya I know that one. I am another 2 hours south of Orlando. Pretty far from GVille

[@mrhermitoable]

@@GhettoWrench yeah, well that would have been fun to put them head to head. I was really leaning towards that ncy one but i think when i placed the order it was sold out

[@cav3man360]
