the honda is heavier because its build stronger and more reinforced
Thank you for doing this video, this was definitely a very interesting video. I would have never thought they were so similar. Man bro John is growing up so fast. Hes gonna be a great mechanic learning from you. Hope you and your family have a great 4th. Todays my birthday 🎉🎉
You and your kid are hilarious what a great father son relationship
Fr.
WOW! This is an amazing video! We love to see you both do this!
Yes I really like the replacement rod inserts
I just started the video and i already love it
Good job keep up the great work
this made my day. thanks!
Great video. You missed the hose on the GX air box. Not there where their is one on the Duromax air box. This could account for the weight difference.
Good catch! I bet your right :)
@@redneckcomputergeek In which case they are most likely the same weight. I think that the Duromax box would be better with the less restrictive air flow and bigger port.
Bro, this is so silly. 0.4% of a pound isn't gonna win a race😭😭
This is my interpretation of compatible performance parts for the D-handle Duromax 440cc electric engine (credit to RCG Racing for engine teardown/analysis):
Camshaft: Any gx390 performance camshaft like the DC308-GX390 308 camshaft (GoPowerSports)
BilletAluminum flywheel with starter ring gear: Any gx390 performance flywheel like the 6623-E (NR Racing)
BilletAluminum Connecting Rod: Any gx390 performance connecting rod like the ARC6272 (GoPowerSports)
55 lb Valve Springs: Comp Cams GP966-2 (use only the larger diameter springs that come in the kit)
Head Gasket: MLS92-027 (NR Racing)
Side Cover Gasket: Any gx390 side cover gasket like SCG420 (GoPowerSports)
Exhaust header: ARSPORT XP16HPE or XP18HPE header
Billet Side cover: 6059 (NR Racing)
Intake adapter: Any gx390 intake adapter will fit, but the adapter will need ported/bored out to get the full flow benefit of the 440cc port like KDMIKMAN301420 (GoPowerSports)
Ratio Rockers: Any gx390 ratio rockers like 390-ROLLRCKS (NR Racing)
Piston: NR460 (NR Racing) - recommended to use stroker crank to get full benefit of flat top piston (#6774 [NR Racing])
Magnetic Dipstick: WEN GNA200 (Amazon)
Hope this helps, feel free to provide input if you have any
Good video
Another very informative video RCG.
HELLO from Western Washington State!
The "Nationally Opposite" location of your family...
Happy fourth july to your whole family Thank you for the video And Thank you to all our military for our freedom every day
Greatings bro I'll love this video the Lord bless you an family 🙏
I have a gx270. What carburetor do you recommend for it? I need to replace it bc i broke the air fuel adjustment screw off in it.
PZ27/PZ30
Could you please provide the NR racing part number for the Duromax 440 head gasket?
No.
i think at the end of the day it boils down to reliability
Unfortunatley i have an older style duromax with the round flywheel cover so i dont know if any of this applies 🤦♂️🤦♂️
Fr.
Hope you know it's a clone lol, I don't get it.
Compare 18 hp vs 11 hp lol
The issue is that the Duromax 440cc doesn't actually make 18hp; it is a theoretical calculation based on displacement and max rpm
Yeeerrrrp.
@@bradensmith888 You can't dyno it???
@@bradensmith888 Well, a 420 made 30 hp on a dyno.
@@fish_R_stinky69 Where can I find that 30 hp engine? I'd like to see it tested
