About had it with these chinese bikes

Dustoff42 · 08-27-2022, 01:19 AM

I just got into riding street legal bikes and so far this bike from venom motorsports has been nothing but problems. its a z250 clone bd250-6. It has fuel injection and is a pain in my ass. At first had issues with the key not turning the thing on. Then fuses starting exploding. My ignition went bad and they are sending another I am going to have to install. The damn thing does not get out of first right when stopping at lights and stop signs, it idling horribly. I rebuilt the damn ignition myself, found the inside metal piece was bent and had shorted two of 4 wires, and got it to work a little just to notice my exhaust glows red A MINUTE AFTER STARTING THE BIKE! I am about done with this thing. It has 18 miles on it and I am about to just have them take it back and drop it off at their place. Not worth the time and effort at this point it seems. I got the one bike from these guys no one seems to know anything about. Just my damn luck. Spent more time working on it than riding and its new.

What?!? Red got exhaust from idle?!?! That's a dangerously lean condition of that's the case. Something is definitely wrong with your bike. Make sure you document every problem with venom. They might need to replace the bike.

Just wondering if you got this resolved through Venom motorsports yet?

Nope. Been giving me nothing but solutions to bikes that are not like mine or offering to send me a new ignition. They said the header and exhaust can get to 1200 degrees. That seems really hot.

Where are you located? Anywhere close to St. louis Mo?

**JerryHawk250** · 09-09-2022, 12:13 PM

So, any updates?

TominMO · 08-29-2022, 06:05 PM

Sounds like you got a lemon. Can happen with any manufacturer. I would work on having Venom send you a new one.

The catalytic converter glowing red, combined with your ignition system problems, seems to indicate that unburned fuel is making its way to the converter. Fixing the ignition misfire should correct the catalytic converter problem.

As for the shifting problem, it appears that you need to adjust your clutch, preferably down at the engine clutch lever on the engine; doing it down there will preserve your adjustment range at the lever on the handle bar. Yours is not releasing enough when you pull in the clutch lever; this makes it hard to shift into neutral, since there is still a load on the transmission shift drum that you are trying to move with the shift lever. You can test and verify if this is the issue by pulling in the clutch lever at the handlebar, then reving the throttle - if the bike tries to move forward, the clutch is adjusted too tight and needs to be loosened.

Venom has not been super helpful about all of this. They offer parts for the bike like a ignition. But other than that they are not helping much. 3500 for a bike that doesn’t work and a company that won’t stand by their products. Nice times. Let this be a warning. Also the fact they market this as a 250cc bike and this is not that at all.

**JerryHawk250** · 09-07-2022, 06:11 PM

It is common practice with all motorcycle manufactures to round up to the nearest 50cc. If you read the specification at the bottom of the website it clearly states 223cc.

I read through some of your other post and issues. Are you still running the stock spark plug? Reason I'm asking is because some of the china bikes come with the cheap Torch plug that usually are junk. Replace it with a good NGK plug. That might resolve some of the idle issues you were having. Another issue many other bikes have had were valve clearance are set to tight. I would do a valve adjustment even if it is new. That alone has resolved issues with quiet a few members on here. From what you have been describing with the red hot exhaust that sounds like a high idle and possible lean condition. You may have an air leak in the intake on the bike. check that all connections from the throttle body and intake are snug and air tight. You can check for leaks while it is running with a can of starter fluid. if the idle speed changes when spraying the connection then you have a leak.

The problems you have are not the norm but do happen from time to time. You won't be the first. Hopefully Venom will resolve the issue for you. They are not know for not taking care of the customer. I know it can be frustrating being that it's a new bike. Word of advise is don't get nasty with them as I can see they are trying to figure it out with replacement parts. All that will do is make them not want to help.

I was staring at a can of that stuff today at autozone. Should have gotten it. That air box is really strange the way it is held together. Thanks that’s some solid advice on the air leak.

Wow! That exhaust is really hot. That's not normal. How many RPM's is it idling at? Should only be around 1500 - 1600 RPM's. A high idle will heat the exhaust up pretty quick.

Exactly 1600rpm like it says it should in the little book that came with it. It’s killing me. I have to get into those valves

I think I'd take the top cover off, not only to check valve clearance, but be sure valves are working as expected. what came to my mind was an exhaust valve not closing properly and some amount of the ignition process is happening past the cylinder.

I think too I would of had the same problem with my Hawk DLX. I adjusted the valves before I ever did the first start and the exhaust was no play tight…my thoughts
