Just received and installed Jim Schmidt's 32mm PWK Flat Slides on my 850.

They came complete with manifolds, air filters, and fuel line, lower cables, and even fuel line.

They came jetted perfectly. I had nothing to fiddle with, just bolted them on!

They are beautiful, and they are fabulous.

I was running a single Mikuni 34 for the past 15 years.

The difference is stunning. These flat slides start with one kick, idle like a rock, and they give the motor a responsiveness that is far superior to a single carb set up.

I expected these flat slides to be stronger at higher rpm, and are they ever, they flow hard right to red line.

What I did not expect was that they would be immediately crisper and stronger than the Mikuni right off idle, and all through the midrange.

One more thing, the price. $445 delivered to my door. What a really good price for a set of fabulous carbs.

This package is being offered by our forum member Jim Schmidt who also offers many other very tasty Commando goodies through his website http://www.jsmotorsport.com

I have no affiliation with Jim, I just want to state how really pleased I am with his product.

Here is a picture:

Ah, Dave.

Why don't YOU buy a set of them, and then take a picture on YOUR bike.

Pictures are SO important, aren't they?
 
I recently added up all the goodies I want to buy for the bike. I think I am going to have a spare Norton when I am done!

Thanks for the report.
 
It does sound like a heck of a transformation. Since I am single carb handicapped this will only be an option I will read about.
 
I would like to hear a performance comparison against properly set up Amals.
 
Phillipe, your question was if these carbs could be fitted to the stock Commando air filter.

I can't see how they could. Jim Schmidt told me I would have to remove even the back plate of the stock air filter to make room.

This is the plate that bolts to the battery box. It came off quite easily.

They are supplied with really nice looking and fitting air filters, see the picture I posted above.
 
Well a big grin and high5 on your exciting report and Jim's efforts to supply these wonders. Its very encouraging report for my Peel project which will first start-run in on 34mm round slide, then try to dial in a 38 mm flat slide, Flat slides work a treat in road going Commando's Yea!.

Maybe my smart money should go to Jim's sweeties on a two into one manifold to feed double each carb's fueling power to a boosted big block that must tippy toe in mud as well as sprint on tarmac. Maybe progressive linkage, one carb for ordinary sane travel response and economy - the other set rich for for thrills.

If anyone could figure out progressive adjustable linkage - racing flutist Schmidt sure could. Hint hint hint. Oh yeah Peel won't have frame hang up issues as carb must mount sideways facing RH side.
 
Correction - you only have to remove the front plate of the air box and the filter. The back plate and ignition can stay in place. see photos below:

Nope. Not needed per Jim.

Jim, if no manifold balance tubes are needed how does one synchronize these carbs ?

You mean using a manifold pressure sensor? I guess you do it the old fashioned way.
 
Hey - I installed a set of Jim's Keihins too - on my '73 750.

Instant shipping, stand by telephone support, bike runs great, never better actually. Happy me.

I drilled the carbs for a balance pipe. Then pressed and JB welded hose barbs into the bodies out of slightly flared 3/16 steel brake line.

I synchronized the cables/carbs with two 5" pieces of wire clipped out of a coat hanger. Stick them just under the edge of the slide cutaway and watch for which one moves first when you start to twist the throttle, adjust the cables accordingly. Thereafter I really didn't need to use two of the four vacuum gauges on a rack of four that I have for synching the carbs on my '86 GSXR.

Is there much difference between using a vacuum gauge and the "drill/stick" method?
