bullylover Posted April 21 Report Share Posted April 21 Not much to choose between the two of them. Go for the one that parts are easier to obtain. I use OKO`s on my three 350 Sherpas. 2 Quote Link to comment Share on other sites More sharing options...
Nick59 Posted April 21 Author Report Share Posted April 21 Thanks for the reply I might go for Mikuni Quote Link to comment Share on other sites More sharing options...
tshock250 Posted April 22 Report Share Posted April 22 I would also go with the OKO, ease of set up over the dellorto & runs cleaner. 2 Quote Link to comment Share on other sites More sharing options...
djr Posted April 22 Report Share Posted April 22 I believe the Mikuni is available with recommended jetting for a bultaco from Inmotion , or Allen's performance ? ( I could be out of date on this, as it's a few years since I was looking to do the same) If a Mikuni ( or Dellorto , OKO etc.) Can be purchased with suitable jetting that can save a lot of time experimenting, although some playing around fine tuning is to be expected, in which case the Mikuni may have the edge as there are plenty of aftermarket jets available on eBay etc. Whatever you choose will be an upgrade on an Amal 2 1 Quote Link to comment Share on other sites More sharing options...

Genuine OKOs available from mid-atlantictrials.com They do a bike-specific set up on each carb, I've found them very good on price and service, ship to UK no problem. One of their OKOs transformed my bike. 2 Quote Link to comment Share on other sites More sharing options...
