Also, I attached a zip with my current tune.

Thanks,

I'll play around with it tonight.

After reviewing and playing around with the software this is going to be a piece of cake to tune. Thanks for links. I'll just have to save up a little Hawk money. In the mean time i'll keep an eye on your progress. What i'm trying to figure out is what kit to get. The Hawk is a 229cc engine. the kit come 150-200cc then jumps to 250-300cc. the 150-200cc kit has a 28mm throttle body and the 250-300cc comes with s 34mm throttle body. Since the stock carburetor is 28mm I would think the 150-200cc kit would be the right one get. I'll have to see if I can find a forum on the EFI and see what those guys are doing.

How much power does the Hawk make? I would say the 28mm will suffice as people are making upwards of 20hp on the 170 and 190cc 4v engines on 28mm carbs.

Specification claim 15 HP. I think the 28mm will work. I like to have everything planned out before I start any project. It would be nice to get 20HP out of it but just a couple would be a big difference. I had access to a MC dyno at one time but the guy went out of business. I would like to do a before and after just to see how much more HP it can make. I know its only a Hawk but I enjoy doing this kind of stuff. I've been out of drag racing for a few years and kind of miss tuning.

Subscribed to this thread.

Here i was thinking that this thread is several years old then i noticed the date posted.
I admit it made me sign up here just to post in your thread

Will watch your progress

Lucas@Air_Lift · 04-07-2017, 01:03 PM

So a quick update. I redid my fuel return line as jerryhawk suggested and it worked great! I also found that the vent tube was pinched my the fuel tank cover, so that is fixed and is now vented to atmosphere. You can see the return line in this picture. I just used a tee fitting after the shutoff valve and before the filter.

What fuel injection?!

I have the bike running ok on the current tune. But, I have noticed that these engines do not produce very much vacuum. I am working on converting to Alpha-N or throttle position based control. I did take it out for a ride around the block and it feels so much smoother.

Unrelated note. Anyone with a Vader have issues getting your MCO from Boom? Its been over a montu and they have supposedly sent it out twice, but I have not received it. It really sucks as the weather is nice and I want it legal!!

**JerryHawk250** · 04-07-2017, 01:36 PM

Glad that worked out. By the time I buy the kit you will have all the bugs worked out . lol

I'll just have to pick your brain when I do get it. As far as your MCO satiation that sucks. There's no excuse for them not sending it out yet.

Lucas@Air_Lift · 04-07-2017, 02:28 PM

Yeah the MCO is dumb.. but usps probably lost it as our local branch is terrible. I also forgot that I had to make a custom throttle cable. The stock one was not long enough and had the wrong end for the throttle body. I used a Venhil (i think?) Cable kit I got on amazon for like $15. Super easy, you just need a soldering iron and about 20 min. The instructions it comes with make it very easy to figure out.

Lucas@Air_Lift · 04-13-2017, 08:46 AM

Quick video update of my progress. Now running on Alpha-N and still no MCO from Boom

Azhule · 04-13-2017, 01:31 PM

I like that throttle response! Can't wait to see how it does after a bit of tuning

They need to hurry up and get the MCO to you

They really do! The want to ride it is real

MOTOXtreme · 04-13-2017, 08:35 PM

While I'm personally not convinced its worth the cost, you sure have done a great job with that install. Been intently watching your progress. Hope your MSO shows up and you get some Vader on-rode action on youtube!

Azhule · 04-13-2017, 08:51 PM

Only added a few hundred dollars to the China Bike... how much is it for the closest competitor (a 125cc Fuel Injected moto)... it's still over 2.5x the China Bikes cost including the installed FI kit

More reliable power over a wider range of temps, altitudes, bar pressures, etc. without having to rejet a carb a dozen times on a ride from sea level to 13,000 feet, from 90 degrees F down to 32 F at altitude... the ECU and sensors take care of all that crap on the fly... FI is well worth the small investment IMO

MOTOXtreme · 04-13-2017, 09:05 PM

Fully agreed. I'm well versed on the benefits

BUT, he clearly has the knowledge to "tune" and install this system. The average person, I doubt would though. Carb all the way for me. Just my .02!

EDIT: hopeful that dont come across snide, its just my thoughts.

I'm seriously looking at putting this on my Hawk. Been tuning efi force induction motors for a long time. Pretty cheap system. I been playing around with the tuning program and is pretty simple.
