Ummmm ... no (bracket maker).

The bootleg PWKs are crap.

You never get a right and left with aftermarket carbs off the shelf.  Most are easy to modify though

that's why I'm a looser. I expect to rebuild from day one.

banshees had VM26's actually.

the knockoffs are huge risk,

5 minutes with a drill and an m5 tap and you have a thumb screw on both sides of the pwk. cap the old hole with a short m5 screw and done. you just reach in and pull the choke up. I do this with the pj34s.  whats the issue? none.

I have 5 minutes. never thought to drill and tap the backwards carb. never read this on any forum. thanks will definitely do.

Of course he does.

Tony cracked the part number code and saved me like $70 🤙

laugh all you want but it works really well for $27 both carbs. they are pz30 4t hero honda bootleg gy200. that stupid choke works well, this bike needs 1/2 choke when cold. way better than dealing with stock cv diaphragm carbs.

mark, they actually have a casting for the idle screw blocked off on the left side. easy peasy. I own the deluxe harbor freight metric tap set.

you have to make sure the slide is tapered on both sides for it on round slides. my guess is no. its a yes on the pwks though, even the knockoffs.

lets be honest. honda twins are NOT super sensitive to jetting. ive owned my share, they are ok being 'close', so glad it works for you.


One proven tip though regarding PWK knockoffs. the useable ones, the good ones, come with hex main jets. the ones with the round min jets are useless.
so, if paraousing the ebays , look at the pics, some will show the bag of spare jets, if theres hex mains in there, you are probably ok. you can fit jjh or jjj needles, and use keihin main jets and be ok.  :twocents:
