Nibbi Racing PE30.

That's great news Dan, and you're definitely paving the way for others to follow, I hope you post up links, part numbers etc. Thank goodness for the tinkerers and performance enthusiasts lol.

I still like the plug and play of the Mikuni though, simple and straightforward. Did you run the Mikuni with your modded head?

Great video too, and you definitely look younger and nicer than your angry profile pic.

I saw the side cover was on lol! Glad you are happy with that carb and love the power you have. I'm more familiar with air mixture, and once I have exhausted the novelty of the original fuel soaker pilot scheme this may be what I want.

I didn't run the VM26 clone with the ported head, but there isn't much need to. As far as airflow capabilities are concerned, it is the same song, different dance, to the PZ30.

About the only part I used that isn't easy to find is the CQR250 intake.

Taobao is the only place I have found to purchase it. It's about 6 bucks, plus another $6-8 to ship it. The issue is, I know many people aren't comfortable with buying via Taobao. If there is enough interest in them I would be glad to order a few of them.

I couldn't agree with you more. Makes all the difference in the world. When I was looking at the PE30 the price was right at $100. A little more than I wanted to spend at the time. The PWK30 works great too but if I had to do it all over again I would go with the PE30 because of the easier access to the idle speed and mixture screw. On mine with the shorter intake tube I can access them pretty easy but the PE30 is a way better option.

With the carb setting further back and out did that pose any problems with the throttle cable and tank clearance?

Also with port matching wouldn't it be a good idea to have the CQR intake first?

Dan, thank you for posting your results. Now I just need to decide if I want the PWK30 or the PE30

Correct me if i'm wrong but does your intake angle to the left side of the bike? Which side of the carb has the easiest access? if it's the left side then go with the PKW30. Performance will be the same.

Yes, the CQR intake does cause a clearance issue with the fuel tank and the throttle cable. That is the one drawback to it. It still works, but the cable will rub against the tank some. I put a small section of vinyl on my tank in the area where the cable makes contact as a temporary solution. If you can run the shorter style intake, this isn't an issue. I would have preferred the shorter intake over the CQR one, but in my case I didn't have much of a choice. I am going to likely be making my own throttle cable in the near future so I can use an angled cable guide to work around this issue.

Dan, did you consider regrinding the angle on the Nibbi intake to adjust for clearance?

In my attempt to adjust for clearance with that intake it actually made other issues lol. Plus, it will have the same issues as the cqr intake due to its length if I did manage to angle it out more.

After looking at these two pictures It looks like they made a change in the frame design from the 2016 model or at least a difference in my hawk. I notice that the vertical tube frame ties in a few inches higher to the main frame than they do on my bike. That would explain why you having an issue with the intake I am using. Those vertical tubes tie in below the carb on my bike.

Bad news for me, the shorter intake was again a no go. I am going to assume that since I have a non factory head, the intake angle was machined more shallow than the Hawks. This is the same fitment issue I have had with the "angled carb adapters"




So with the 48 pilot installed it started right up, but it needs alost 3 turns out to hold a semi-steady idle, so the 48 is too rich, and the black smoke from the muffler when I blip it would agree. That said, it isn't too far off either, because when it was dead cold it idled great, and tapered off once it warmed up. Almost like running with the choke on. It would seem they were not kidding when they said it was a high velocity carb lol. Once the bike cools off a little more I am going to jump down to the 40 they included with it and see how that does.

Some research I did confirms this as well. More powerful 250's that came with a PE30 stock are using a 50 pilot jet.

That must be it. If that piece of the frame wasn't there I could probably just barely make it work. The aluminum Nibbi intake would work for sure if that bar was just a bit lower too.

Just purchased the nibbi and a new head to port and polish. Cant wait to break out the porting kit and make this thing happen. Just hoping the head Jerryhawk250 got is the right one.

[G2ic22]

Here it is fellas

[G2ic22]

So I cant seem to find a way to get the CQR intake on the English taobao site. I've narrowed down these two going to buy both and even if I half to customize it as Long as it bolts to the head I'll find a way!
