Looking for carb recommendations

[dalegoldston]

I have a 421 serval and run a single 35mm keihin carb. Looking to go to dual carbs. I understand it will run alot better with duals. Suggestion on size and shop to buy from. Thanks for the help.

What kind of riding do you do? Since its a serval I'll assume bottom and mid are important to you so I'd recommend PWK 33s. If I had to guess I would say FAST will be having a Black Friday 10% off sale as they had in the past which would be a good time to buy them.

28 pwk all day. Get some extra bottom and longer ride time 

[dalegoldston]

I ride a wide variety of ways. From trails to dunes, probably more trails than dunes though.

I wouldn't be scared to get another 35 and run it since you already have one. If you decide to try 28's or 33's in the future you could always re-sell the 35's and get a smaller set if you wanted too.

Mostly trails then 28 might be the way to go. I certainly wouldn't go bigger than 33s on a trail bike.

Since you already got a 35mm, just buy another one and be done with it. Buy UPP intakes.

I had 2x35mm on my trail 421.

35 on a 421 

 

DUALS not single. These are twins meant for two carbs.

If it were me Id just buy the extra 35 mm carb and filters and intakes from FAST like said above.  you bottom end will still be decent depending on your pipe choice.

only thing you will have to see if you have a problem with is the MPG, you will go through more fuel obviously 

[ClaudeMachining]

And if you dont like the 35mm, sell them and buy 28 or so

Thanks for the info. I may search for a pair of 28s or 33s. I like the idea of two new carbs. I will see what fast has to offer.

I've had 28s 33 and 35s on a serval and 28s are my favorite hands down. Longer ride time and far more responsive on the low end.
