Thanks so much for the great information you have provided us all with. I just got the bike so right now only mods I have are a gutted cat and upgraded carb but I haven't received my pilot jets for it yet so still pretty tame although the carb and opened exhaust made a huge difference over how it was out of the box. Hardest thing right now is probably going to be getting parts as shipping is super backed up. I really appreciate your help.

It was way more than just me. My bike is the end result.of a community effort in mods, repairs, and upgrades. I had a.few contributions for sure, but I am hardly the only one deserving of credit. There is a load of good info all over this site. I just collected it all and put it in one place.

Well your videos and gathering of information into none place for everyone to find has inspired me to not only buy a chonda but do the engine build beyond the usual bolt ons. I ordered a cam and roller.followers along with a timing key from Henner motorsports, i believe nits a 298 duration with no lift increase. I also snagged an ebay head for porting so hopefully I can have all the parts ready in a few weeks to just sit down and swap them.out. Not sure if I'll attenpt to port it myself.or send it off for a.professional job. Not sure my mikuni clone carb will be up to the task but I'm going to throw some jets at it and try it before buying another carb. Is csc the best place to get the head and base gaskets? I considered eliminating the base gasket but hate to assemble it with only gasket maker and have a leak. Probably not worth the risk for the minimal gain. Will probably be asking more questions but will.let.you know how it goes.

Glad it had the intended purpose. I always suspected that a lot of people held back from getting into these bikes because of so many unknowns. It's still a bit much for some, but it definitely makes people more confident being able to simply find information.

As far as the gasket question. That is where I ordered mine. There are other gasket sets I could help you find, but you may be waiting several weeks to get them. The CSC Head gasket is the single piece steel gasket as well. I am not personally a fan of eliminating the base gasket either for several reasons.

Honestly, feel free to start your own thread on your build/project. We like to follow peoples work.

So, where was I? Oh, right, having bad ideas...

Been a while since I had anything to really update about, but I can toss a few things in here.

First, I did install a 31 tooth rear sprocket, and while I have no doubt that my bike pulls stronger than my first Hawk, I think I have crossed the threshold of too much gear for my own taste. I am now debating on going 2 teeth in the other direction and putting a 35 on the rear. For now I am putting the 33 back on.

So on to one update/experiment. I am fairly certain that my ignition coil is a bit wimpy, and getting wimpier as I go along. Maybe it's the added compression, or maybe I need to run a smaller plug gap due to said compression and ignition advance, but it just doesn't want to pull as strong up top any more.

I could do another JerryHawk250 Coil on plug mod, and I really did love that the last time, but a part of me wants to stick with the KISS side of things, so I am going to give this a try first, a Nibbi branded ignition coil. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I have been quite impressed with their quality thus far, so hopefully that trend holds true. The reviews seem promising at least, and I will obviously add my own to it. I do plan to keep using my taller NGK plug boot and shortening the wire as needed. In any case, it can't be any worse than stock, and it's only $14

So the real interesting bad idea part. I am going to switch back to a PZ30B from the PE30. I picked up a version that takes the same jets as my PE30, so I have jets galore to choose from, and I still have all of the other stuff that comes with it.

Not sure if I will even stay with that swap, but I am curious as to how it will feel and perform. I do know that I am a bit tired of the sensitivity and constant fiddling the PE30 seems to demand, so at the very least I can take a break and enjoy just riding. Plus, well... I miss the accelerator pump.

**JerryHawk250** · 03-10-2021, 07:49 AM

Yeah, stock coils are kind of weak. There was a noticeable difference with the coil on plug. The stock coil started misfiring at higher rpms. The Coil on plug resolved that issue. That Nibbi coil will probably be a good improvement as well. They look to be larger than stock. I might have to try one on the Ghost.

China Rider 27 · 03-10-2021, 11:59 AM

The PZ30B! Bravo!

I haven't quite reached the point where it is noticeable cutting out at higher RPM, but I can definitely tell that it isn't always sending a strong spark. You can hear it in the exhaust though, just a touch. Might as well get a jump on it and maybe get a slight upgrade too.

What can I say, as much as I loved the increased pull from the PE30, I can happily sacrifice that for the punch of the PZ30B. There is a carb I would love to try that would give me the best of both worlds, but it is nearly $200 on its own, and would need a push-pull throttle installed. Then I would have to start the jetting from scratch all over again. I just don't feel motivated enough for that whole affair.

Megadan · 03-11-2021, 09:26 PM

Typical Nebradka weather. I got in all of my goodies today and the weather got cold again and it's going to rain and rain/snow for 3 days straight.

**JerryHawk250** · 03-12-2021, 07:54 AM

The weather here this week was perfect. Highs in the mid to upper 70's. I've been taking the Ghost to work every day but that's all going to change by Sunday. Looks like rain most of next week.

Oh well, It was nice while it lasted.

Megadan · 03-19-2021, 02:32 AM

So I dug my Hawk out and blew a bit of the dust off of it. Haven't gotten around to installing any of the previously mentioned parts, although that is on my agenda this weekend. Figured I would fire it up to get the oil moving a bit and go put a bit of air in the tires... Aaaaand the battery is gone lol. Tried to revive it, even got it to crank over, but when I got the fuel station and shut it down, nada. Had just enough in it to turn over once and then click the solenoid (that added compression doesn't help much btw).

So, I have a Mightymax sealed lead acid battery on the way via Amazon, should be here Sunday. Gives me some time to do the work I want to do, assuming I don't get too distracted with doing fun things like fishing.

China Rider 27 · 03-19-2021, 11:42 AM

Ice fishing maybe! Whatever came of that 32mm carb you were going to try?

I tried it. Not worth doing without a much more aggressive cam.

Megadan · 03-20-2021, 01:33 AM

So I got a bit done today. Not as much as I could have, but it was sunny, 58 degrees, and I wanted to go fishing.

Pulled the tank and plastics off and removed the PE30 setup, and then got my PZ30B ready to go. Going with a Nibbi brand washable style filter for fitment reasons, as it clears the side panel with room to spare. I am actually pleasantly surprised with the quality of this filter, no big holes or other gaps.

A nice side by side of the two setups.

I am sure some of you are wondering why I would do this, but it simply comes down to usability. The PE30 is great if you are chasing all out performance, but it is a fickle and finicky thing to get dialed in, and with the slightest change in weather it starts to run off and needs adjusting. My main goal is to use my bike as my main commuting vehicle this year since fuel prices are going up and it gets almost double what my economy car can manage. Thus, having a more set it and forget it friendly carburetor will just make life easier. If I lose half a HP, oh well, I have some to spare at this point.

I will have to do a tiny bit of jetting as I never ran this type of carb with the ported head, cam, and style of filter. I am going with a known quantity on the pilot jet and starting with a 45, which should be close if maybe a tad big. Main jet is anybodies guess, but I went with the same main from the PE30 for now, which at worst will be too big and I can go down from there.

While I had the tank off I went ahead and installed the Nibbi coil. I made a separate thread for that one, found here if you haven't seen it yet.
http://chinariders.net/showthread.php?t=28393

So I am going back to the 33 tooth for now as I just love that gearing combo. I do have a 12 tooth front that I may experiment with instead of a 35 rear, which is almost the same gearing anyway (12/33 vs. 13/35), plus I won't run into any potential chain length issues that way.

Another thing worth mentioning is that I will be reinstalling the fork brace. I dug it out of the box it was in and "persuaded" it into a better shape so as not to cause my forks to bind up. I will be doing that install along with the rear sprocket either tomorrow, or Sunday when my battery arrives.

I also did install my TT250 seat, which IMHO was worth every penny. It's not the greatest seat ever made, but compared to the Hawk unit it is a step in the right direction for sure.

China Rider 27 · 03-20-2021, 10:37 AM

Good write up, nice work. I run an 11 tooth front with a 35 tooth rear somewhere as I remember around 3.0 ratio as I use my HAWK focused on off road in up and down terrain. Many are focused upon top speed, when all the fun is in the mid range! A couple of years ago I studied your work on the PZ30B, put one on my HAWK and confirmed it "is a performance improvement", especially so with low gearing it provides as you call it "punch." Sometimes I think about putting another carburetor on my HAWK, then I go about my other business!
