PWK28s for RZ

[2steve]

These look ridiculous, maybe they are, but the price looks good and if the see-thru bowl will last, it would be handy:

More down-to-earth here and in a Sudco box. Real Keihin and looks like it's ready to accept injection oil. Maybe worth the extra coin?

Trying to start the carb kit on the RZ.
Carb mouths are bigger, so would have to plan for angled(?) UNI pods and I'd want to get the cable arrangement right the first time.

the second ones are the same I bought and have used. get JJH needles from jets r us, swap em in. you'll be between a 145-160  main. 38-42 pilot . ive tuned a few rzs w these

Ive seen quite a few people complaining that the see through bowls dont seal well and they are constantly fighting fuel leaks.

ive used the clear float bowl ones on a project with no problems, one advantage of that particular type is that they have an adjustable power jet. i have literally leant down and dialed the carb at wide open throttle, right up to spluttering, then back down a bit, great fun!

Yea I got the 2nd ones(SUDCO) and they definitely improved performance overall. I was able to find a pair of PWK30 mm for about 50 dollars.  Sudco is gone now so there may be alot of those floating around ebay.  when I initially purchased them they sent me 3" exhaust flex hose instead.  It took them about a month to get that all straightened out...

the 'sudco' ones are copies. they are excellent copies but are not genuine.. imho not that it matters, they work well and tune exactly like a genuine pwk. just 0.02

A few years ago, I did genuine KX80 PWK28's off Partzilla on my LC. They were $115 each, but are up around $200 each now, I think.

They fit right in to the stock manifolds, but UPP flat back urethane manis are way better if you're using VForce reeds, etc.

I used the stock throttle cable(s) with angled top adjusters off eBay to get the cable length right, especially at the oil pump.  Oil bung fittings were off eBay also, and I installed them in the top boss next to the choke plunger.

I'll look for a link to the adjusters.

JB Weld in the photo is to secure the oil fittings in a hole drilled in the top engine-side boss?

Jim uses the JB to keep his Tecate from sliding off the table

Usually, but in this case, yes, it was to secure the oil fittings.

These are what you need for the cables.  Without them, the oil pump cable from the splitter is either too tight, or too loose (can't remember which) and isn't able to be adjusted properly. Also gets the cables headed in the right direction toward the front of the bike.

I had bad luck with the cable ends being able to fit through the rather tight ID of those angled adjusters. Got one left after abusing one of two to try to make it work. 

However, just ordered a pair of genuine PWK28s from eBay - old Sudco.
$150 for the kit made up for a Banshee. Comes with a split cable with no oil pump leg. Also another needle and other extra jets. Maybe I can use the carb legs off that cable and graft them into an RD400 unit splitter housing with the RZ oil pump cable.

I can guess that the oil pump cable was too long to be able to take out all the slack. So, I see what you are saying, Jim.

Can you tell I don't want to pay Ed Toomey $700 for the whole RZ kit?

Thanks!

@elliottles1 - what you said really tempted me to consider those blue ones with the clear bowl and adjustable power jet.

post the link, i have doubts they are genuine.  not saying they arent good, just saying. is the slide screw brass or plastic on the ones you bought?  and youre going to love em regardless.

They look legit. Don't know the deal with the possible brass plug in the power jet hole, etc. The included cable won't work, but parts of it might. Hoping for the right jets.

[m in sc]

they are 100% copies. good ones though, those are identicke to the ones ive run

[mnein]

Buy an RZ with crappy carburetors Steve! It will be fun they said. I pray the PWK's treat you better.
