hi ss27, as Jerry and some of the others have posted....check your valve adjustment, there is a ton of info on suggestions for a new bike, lock titing, valves, etc...as what I call the masters of the china syndrome. congrats on the purchase....post some pixs

Just talked to American Lifan. The only way to properly adjust the idle is to take the module off and send it to them for adjustment. They supposedly have the one and only device that can reprogram the module.

I deffinetly plan on doing this probly will go through the whole engine. along with locktighting all critical fasteners. if they don't already have Loctite/nylock nuts. it might be a few day before. I ride I'm going through this with a fine tooth comb. But as soon as it hits my door I'll get you guys some pics I've yet to see a red one not even a picture of one. just the orang and green ones. is all I can find a picture of. so I can't wait to see it.

I would check valve adjustment first before sending it. It's almost a guarantee that it needs adjustment. Otherwise you will be like a dog chasing his tail. lol Seen too many guys on here trying to adjust carbs and in the end all they needed was a valve adjustment.

At least there willing to straighten this out. and they might have the only module for now. but if these get popular enough. someone will hack the ecu eventualy hopefully they do. modding would be easyer if you can tune it.

Thank you that red with the black rims looks awesome.

WOW JERRY!!!

AMAZING ISTRUCTIONAL LINK FOR THE VALVES!!!

My TBR7 is new ( 56 miles on it ).

Have not touched the valves yet ( busy mucking about with carb, clutch, fork oil etc. )

BUT.. I will want to mind those valves and that link is pure gold!

In fact, for others, there are a bunch of other cool manuals on that site that surely have cross appeal for the HAwk or TBR.

Sure I can watch vids, but those guides are great!

I don't know if the TBR or X-Pect are like the Hawk as far as room but on the Hawk the Valve adjustment can be done without removing the tank.

Thanks, I did see Motocheez do it without removing.

I'll take a look..worst case I'll yank the seat off.

Probably the coolest part about these bikes is the ease of working on and the lack of care in tinkering...meaning, if I bought a bike for $7k...I would stress over diving in head first.

For $1,700 brand new.. I had the thing ripped apart day one without a worry i the world....

This sounds like a very sensitive TPS...Throttle Postion Sencer..
it is detecting small involuntary throttle movements you are making..


What happens.... every time the throttle moves the ECU thinks you are
going to accelerate so it richens the mixture.... but when you don't it leans the
mixture back off again.... that gives the surging sensation..
rich/lean/rich/lean and so on...

try loosening the throttle cable slightly...give it more free play...

Hawk like bike with what brand of EFI? It’s not Delphi but maybe FIA? Still rear drum and skinny fork which is weird cause nothing in China like this really is forced like it
OHC 223cc engine prob like my CQR or the slightly better built style / not sure

I found that kit too over a years ago. Always been tempted to try it but bikes running too good as it is. Here's the link for anyone who wants to try it. You will need the 200cc kit and upgrade to a 30mm throttle body https://www.aliexpress.com/item/3278...ddresstype=600

I can appreciate the work of tracking down an EFI conversion and it’s great to upgrade any parts on the Hawk. But how reliable is a more complicated gray market system at what benefit over a carb. We don’t get emissions checked. Maybe a few more miles per tank. The carb is foolproof super simple to repair and a replacement is sub $20. I’ve seen the carb models of China bikes on back order this summer and I’d assume it’s cause the pending EFI release. If I had a choice I’d go carb. Even if this was a Japanese bike. It’s like trying to make ice cubes more complicated.

Keep it simple stupid and I’ll get home when I’m over 10 miles off pavement roads.

No go on this...
