Scooterotica

Thanks for all the information. Just to clarify, I am considering an almost new 28/30mm version with a complete set of jets and needles to go on my newly fitted Casa 210.

>>these carb kits can be bought in the uk...

Those are not the same, those are the other type I mentioned.

Parts from Thai or Taiwan: Any standard PWK part will fit on these. (They will not fit on the other type.) The BGM and all the other are made in Taiwan, btw. Several brands.

You don't need to drill anything out on these. I think we tried that when we had a couple people asking about what turned out to be the float not opening because of a plastic bit there. Also, if you don't have the float adjusted right, you will have problems with running out of fuel early, or overflowing. Same as other types; have to be gentle opening it up or you'll bend it.

210 Casa: yes, I'd use 28/30 with a tuned exhaust.

Thanks.

big michael from darlo s.c. had loadsa bother with his, but it turned out to be the float height, a few bends hear and there , and runs lovely now, on a rapido225. fitted a couple of these, one went on and was near perfect out of the box....... belter! the other? if i didnt chuck the c**t over a big wall......... while the owners jaw was on the deck.......i would still be trying to jet it in now! if you like a fiddle about and money is tight, have a try. if youve got the cash, and want quality, buy a mikuni. personally , i"d go mikuni every time........ thats because i run an old solid mount dellorto! (i got it for nowt, so cant complain!)

That's what I'm running at the moment, so any move to a more modern carb should be for the better

Dellorto's and TMX's seem to get a thumbs up and loads of info available...

This is a complete kit, carb, inlet, rubber mount, throttle cable, set of main/pilot jets and two needles so I shouldn't need anything else. And price is low
BTW this has been running on an Imola/Mugello apparently with no issues.

Was on Evil Bay and I got beaten to the post so it's all mute now

I had 2 PWK type carbs from Scoot RS, first one a genuine Kehin did not run well at all just didn't flow fuel( Carb returned/exchanged no probs ), the second a OKO copy is still on now and runs well ( 28/30mm on a iron 200 ) after @ 2000 miles or so, so thumbs up. Dellorto carbs can have their problems even after all these years, a mate of mine went thru a couple of pistons etc even after having it set up on a dyno etc cos the Dellorto was duff, quite a few respected tuners out there advise having them checked/blueprinted to get best results. As with all this tuning lark some elements will always be affected by lady luck at times.

A genuine Keihin is a quality carb. I stand to be corrected but I doubt ScootRS have ever sold genuine Keihins.

Three other points.

If you're going to go with the ScootRS version, which wouldn't be my first choice [totally personal opinion], don't use the choke converter, and don't use the angled elbow they sell for the throttle. Unless these have changed over the past 3 years, they are poorly made.

The SCK choke converter is better although I seem to recall actually using the ScootRS spring with the SCK kit on both mine.

Float height. ScootRS tech pages are pinched from US 2 stroke sites, I think. They refer to setting it at 19mm. Don't, 21 or 22mm is right for most UK atmospherics.

Lastly, the ScootRS manifold may possibly leave little clearance, if any, between cylinder cowling and carb. A downdraught manifold holding the carb up at an angle is better.
