What carb would you choose for a '03 220?

Post by TwistedRoot »

Just wondering what everyone thoughts are on the best 220 carb replacement? According to these parameters:

No elevation change factor
Pro Circuit Platinum Pipe / silencer
Stock motor


I have an RB carb on my 200, and its great. As we know they are unavailable. Thx for the replies!! :mrgreen: :partyman: :busted:

I thought Ron Black was still selling new, modified carbs but would no longer modify an old carb. Of course I've been out of the loop on that for almost a year. If I couldn't get a new carb from Ron, I'd go with Lectron.

RB carb all the way, hands down! If he isn't doing new carbs still then the PWK 35 AS. I have a Lectron on another bike and I'm not sold on it. Maybe if you like a more mellow feeling bike, and no real tuning after you get it set up, then the Lectron might be for you. Just know they fit like crap on a KDX. Of course, I only change needle clip position on my RB carb from winter to summer and the main only if I ride above 5000" by one size. Super easy carb to tune IMO/IME.

Looks like RB will sell you a new modified OE or AS carb. I have his carb on my KDX and love it. I have always wanted to try a Lectron.

If you lend someone $20, and never see that person again, it was probably worth it.

As of my last email from Ron in mid August, he didn't have any carbs and didn't know when he would have them, if at all.

I am not crazy about the price of the Lectron and the issues with the install. Although I know many guys have made it fit, I want a bolt on carb with zero headaches esp after seeing the price!!!

I've ridden a 200 with a Lectron, stock motor except for an FMF Woods pipe. It is a sweet ride with a wide and predictable power delivery and revs out really high. My 220 has a new OEM RB modified carb. Engine has Boysen reeds, FMF Rev pipe and RB modified head. It is **** hot compared to the 200 in my opinion; feels more like a race bike than my buddy's 200. I think I rev out just as high as my buddy's 200 now but haven't done a side by side comparison since the RB mods. Not a fair comparison since there is more difference than just the carbs. Given my choice though, I'd take the RB first.
