This is Bullhonkey misinformation, The Engine with Major Excessive Valve Lash will simply not run long before the Valves Don't Open at all. At that Point the Starter Does Not have Enough Snots to Turn the engine over. There is just under .300" of Valve Lift with .250=1/4" so imaging that the ValveLash being .250" or more it would not run at that point. you will never be able to break those parts mentioned. There are no seals up there and the Valve would be closed so It can't bend. just aint gunna happen. Ok, thanks for explanation. To make things simple, bike has mot due in August, in your opinion will it be ok to drive it as it is, or will it cause some problems and should that valves be sorted straight away? Thanks |

Thanks all for your replies. Will get carb cleaned, idle and valves adjusted. Last thing that worries me is fuel consumption. 20 miles for 3 litres (nearly 3/4 of a galllon) is way too high for me. Let me tell you that bike wasn't ridden too harshly, average speed would be around 30mp/h.

Thank you Elcamino121, is it risky to drive scooter as it is, can any serious damage to it be done?
Anyone else please? Do you share elcaminos opinion, or have different views? Thanks.

Hello guys. First of all, I'd like to let to know that I'm a complete newbie. A week ago I bought used scooter, hmc haze 125 powered by gy6 engine. I noticed that when started cold it works very inconsistently, revs go up and down. Sometimes it cuts off stoutly after start. I recorded short vid to give you a better idea of how it sounds
When it's warmed up it runs little bit bette, but still isn't smooth. Bike was ridden for about 20 miles without issues. I was surprised to see that it used almost half of tank of petrol doing these 20 miles. I'm asking for your advice before I'll go to garage (don't want to get ripped off). Now, I have few questions about this issue
1. Is engine on its last knees?
2. If it's not engine what it might be?
3. What will happen if I carry on using the bike as normal, will it shorten engines life or performance?
