Hawk pilot jet seems I may have found it

That’s what I’m thinking
Drilling the pilot is also ok if you don’t screw it up.
I think 90% or more cheap Chinese bike owners wouldn’t ever see or make a big difference with changing to a Mikuni carb - they only want a smooth running bike, and a handful might like to learn n tune their carb better and a few might move on to an upgraded carb with some improvements and all the while spending not so much in the progress from stock to the end results.
That’s my thoughts etc and I think it’s a good way to help/serve/earn from it.

Haters will hate others will find the idea good and others wouldn’t bother with Chinese bikes - all sorts of ideas out there

Do you know the username of the chap in TX “project next”?
I’d like to ask him what the stock pilot jet was in his carb
In my kit I add in that style #40 as well as keihin #40 etc
Reason being the set should then cover the 3 known?! pilot jets at a slightly increased size from stock
I thought each #40 but if hawk type is #40 I’d need to at least add in #42
Common keihin #40 and that short style like in the storm #40
Cheers in advance

I would love this as I still have the stock carb with the mikuni jet you can change but not the pilot. It runs fine once warm but I have to turn the idle up to get it to start from time to time. Would the pilot jet help this?

Jumping from 25 to 27 at the pilot made a huge difference in my starts and idle.

I hope so. Waiting patiently to see if this is the one.

Me too! at 117.5/27 with 1.5 turns on the mix the bike still backfires some if you release the throttle over 4,000 rpm, not near as bad as the 115/25 or 117.5/25 and it seems to start quicker. With the 17/43 or 41 gearing it still won't roll much over 60-62 mph though. In a month or so I'm thinking I will order the 44 or 45 cog and just live with the old 64-65 max. Not enough HP like the Hawks to ever get that 70 max.

Drilling out the pilot jet is easy. # drill sets with pin vise are available on eBay for 4$. For my Hawk a 45 pilot made a huge difference in idle and off idle performance .016- .017 will get you very close to a 45 pilot jet. The number set I bought were actually metric and one bit was 45

The pumper carb route is honestly my new favorite, but a well tuned VM26 clone is pretty darn good.

I don't think there is much skill involved in setting up the pumper either. It's literally adjusting one throttle cable and an adjuster screw to get the timing of the spray pattern correct. I am actually considering making a video for my Youtube channel just on the pumper and how to set it up. I am just waiting on new batteries for my Go Pro since I let my last ones go flat (oops). Once I have that video made I will be making a thread with all of my previous "adjustment" information from my bikes thread and making it a one stop shop that I can link in my Information page.

Don’t get me wrong
Your bike your money etc
Just looking to offer a good thing for most people and make a buck - not hiding the facts etc.

My system should relate to almost all bikes or ATV with a 200-250cc air cooled engine with the piston going up and down so vertical, not only a few know model names as you need or should focus on engine type n carb type etc.most consumers will find this will relate to them. Ignore the brands and focus on parts used in china bikes as that opens up more options or repair ability

But it sure would help all if the systems shown are more valuable or viable so good choices can be made regardless if:
Tune stock carb with a few simple bits like washers bolts jet etc
My first tune kit and extra optional pilot jets
Minkuni clone & genuine jets
Add on to my kit the PZ30B pumper and more pilot and in between main jets from first tune kit.
Then you have other carb options and this list can go on and on.

I’ve sold 90 or so “first tune kits”
I call that some success

If I can improve the set and system as well as have near every China bike and ATV owner see it this number could become endless maybe

Or where to show the system once I’ve got it locked in?
I’m not American I’m not that familiar with that market be a long shot.

But the principal I’m sure is great for most.

I will say this, since I got into this scene about 2 years ago the number of owners/riders/etc has increased quite a bit. Even back then there was maybe 2 or 3 guys on youtube doing any sort of videos related to these bikes, and only one that was doing it consistently (Motocheez). Now you have 20 or 30 guys posting vids on the regular.

I think as time has gone on, information has been collected and preserved in place, and there are more examples out there of these bikes being reliable and viable options the number of owners will steadily increase. I know I wouldn't have even considered the Hawk until I watched a few Motocheez videos and then ran into this forum and did some reading.

You're absolutely correct.. Motocheese paved a road on YouTube for a lot of cb enthusiasts. I know he's pretty hot on the TaoTao right now but I'm willing to bet if he gets his hands on the new fuel injected Hawk it'll make for some great vids.

Dang! I just bought a kit from you off ebay, do you have a link of where I can find the pilot jets for the Hawk stock carb NzBrakelathes?
