update to... Hawk carb question
************************************************** ***********
ok so update The carb that is on the bike is a PZ30 and is running with 98 and K40A and there are no notches. So I know (well my reading of forum posts) if I run a Mikuni at sea level mostly road riding, I would (probably) use a 115 and a 30. so what is the Khein versions of these, is there a chart somewhere showing comparisons? so I know what sizes to try. Also when ordering a replacement carb on line, I see a lot of VM26 30mm and PZ30 in the same listing, am I wrong in thinking they are 2 different things? As always thanks in advance ************************************************** ********** So I am getting to a point where I will hopefully have the bike assembled and ready for first start in the next week. I have done some upgrades whilst putting the bike together, Ebay exhaust (still needs to be fitted) K&N, this bike will be mostly street riding at sea level (ish) so have changed the sprockets to 17/42 with a new chain. So to my question I have never really tinkered with a carb before. I have read a bunch of forum posts and my head is spinning. If I buy a Mikuni vm26 30mm clone, i can use oem mikuni jets. was looking at this carb https://www.ebay.com/itm/Mikuni-VM26...0AAOSwPOBc6LKF Dont know what jets it has (if any) out the box. I have read a bunch, as I say, and want to check if my understanding is correct.....I 'think' I will need a 30, 115 if I understand the various articles and wanted to know if someone could yeah or nah me. Also anyone have their favorite youtube posting of someone installing these and tinkering. Thanks in advance

Maybe...most likely...

They helped me find the right ones for my "genuine" Mikuni on my Orion RXB. I say "genuine" because the US Mikuni importer has never heard of the VM26 Flange mount, so I think it may just be something for the China and South American market that someone else imports. The Mains are: Mikuni N100.604 (M21 Jetsrus #). The Pilots are: Mikuni VM28/486 (M24 Jetsrus #). Cost is about $7 for genuine Mikuni or $5 for quality aftermarket. At sea level I am not sure, but that 115 you see is likely for lower altitudes like yours. I am at a Mile High and was able to keep the stock 100 Main, but had to change the Pilot to 30 from the stock 20. Left the needle clip in the middle position.

Before you go ordering jets for the clone carb, make sure you know that it does have the proper pilot jet installed. Some sellers of the Mikuni carbs are shipping off PZ30 clones with the Mikuni name cast into them (My PZ30B says Mikuni right on it, but uses Keihin jets). There has been a few guys on here who got a "Mikuni" with a non mikuni pilot jet installed.

Jetsrus can help you out
Quote:
These flange mount carbs are not something he generally deals with, as I think they are pretty much used for Chinese engines. As I have noted before, the US Mikuni importer (Sudco) does not import these and the gent I corresponded with had never heard of them. What Mike did was make an educated guess and sent me the measurements and diameter at the thread of the Mikuni jets he thought would work. I took out my jets and measured them. Also, I compared the photos to the actual. Made the order and they fit. If you think they are maybe Keihin jets after you do the measurement and visual inspection, but before you buy, then make some measurements of what you have and send him photos. He will be able to figure it out.

I have read lots on mikuni and 30 and a 115 for my type of riding and altitude, but what size is a klein in comparison. Is there a chart someone can point me at to show this?
Thanks in advance

Roughly, a 45 pilot and the mains are roughly identical if you use the cheaper jets from amazon.

No prob. Just keep in mind that is a rough guesstimate.

Dan, (or anyone else :-) )
is the following a (sort of) correct statement the PZ30 style carbs use Khein (GY6) jets and the Mikuni clones (if they are not Mikuni stamped pz30s) use the Mikuni style jets (i realize this 2nd statment is sort of redundant, but for completeness) once again, thanks in advance

So I stumbled across the following chart at Jetsrus that shows the comparison between the different jet manufactures and the sizes.
https://www.jetsrus.com/FAQs/FAQ_mik...ihin_sizes.htm Im still not sure how to tell which carb jet style is in the knock off carb I have as in another post Wild Dog had said that ....... with most of the chinese carbs, .. you may have a PZ30 that use keihin jets or a PZ30 that use mikuni jets..
