Saw this on eBay and was wondering if anyone had used this kit or has any knowledge of the head compared to other big vavle heads. The 23mm intake and 20mm exhaust are bigger compared to other heads I've seen. www.ebay.com/itm/221239696272?redirect=mobile |

I bought this kit: www.ebay.com/itm/100cc-Big-Bore-Performance-Power-Pack-Big-Valve-Performance-Head-Black-Exhaust-/151047655363?pt=Other_Vehicle_Parts&hash=item232b244fc3It includes a big valve head with the same size valves as the head you're looking at (according to the seller). The box the head on my kit came in looked exactly like yours too (Growsun), so I'll give you my 2 cents. I upgraded from all-stock parts to the kit you see here, so I can't tell you how it compares to other heads. In my experience, the whole kit runs real well. The only problem I've had is the base gasket included in the kit melted after a couple weeks. I've since replaced the head and base gaskets with a Hoca set and it has been scootin' along just fine ever since. Also, I ride a Boatian 50cc, so I don't know if the odometer registers in miles or km, but I have put about 500 on the odometer since I've installed the kit and I have no complaints yet. Hope that helps! |

Melted a gasket? Wow. First I've heard if that happening to anyone. I've already got the airsal 50mm piston which I like. I'm mostly just interested in the head and would use the piston on someone else's scooter.

I've used that head it has bigger valves, but the ports are crappy and the valves started to leak after 1500 miles on my stepsons scoot.

And that pretty much knocks that head out if the running.

Millsc,
Even though it didn't last long how was the performance with it?

It performed good till it failed, for the price I guess its worth it. I'd do a scrappy Buford head way far the best even over the hoca.

Do all the big vavle heads from scrappy get the Buford treatment that you have spoken so highly of? I'm needing that extra boost of power before I move up to a taller gear. I'm running the 16/50 scrappy gears now but I've had a set of hoca 18/46 gears just sitting there. I'm affraid I'll loose all of my torque or won't be able to hold speeds since I haven't maxed out the motor.

Hey everyone how's everything running.you all know who I am if not im the one that done big valve heads and porting for scrappy too answer a couple of questions. No im not doing heads for scrappy and really don't know if im gonna get back into doing them anymore. So for now I am going to take a break. I will still stop in from time to time. Take care and rember what I always say. Cover that head don't be dead. Thanks...buford.
