dpyam Posted December 13, 2015 Report Share Posted December 13, 2015 A less worn TY175 carb! Seriously though, what are you trying to achieve - more power, more low rev torque, other? Quote Link to comment Share on other sites More sharing options...
bezaboy Posted December 13, 2015 Author Report Share Posted December 13, 2015 To replace worn carb and if I can get extra from it, then bonus. Quote Link to comment Share on other sites More sharing options...
smokey125 Posted December 13, 2015 Report Share Posted December 13, 2015 I would try giving it a full rebuild first. You would be amazed how much of a carbs workings can wear and cause poor running. Get it properly cleaned if you can get it ultrasonically cleaned it's worth it. Then treat it to some nice new part. I would look at all seal, o rings and gaskets, needle and needle jet, possibly slide and air adjustment screw. I've never used them personally but these people have come highly recommended. http://www.motocarb.com Quote Link to comment Share on other sites More sharing options...

smokey125 Posted December 15, 2015 Report Share Posted December 15, 2015 Having looked at the price of parts and the price of OKO carbs I would be tempted to try one of those first. They seem to get some good reviews as well. Quote Link to comment Share on other sites More sharing options...

I certainly found the irony in a company that started out copying Keihin carbs warning about cheap copies! Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted January 13, 2016 Report Share Posted January 13, 2016 Could you compare it to eg. Jitsie CNC master cylinder covers and Apico CNC master cylinder covers....? I mean they're all essentially the same aren't they with some slight variations... Quote Link to comment Share on other sites More sharing options...
woody Posted January 13, 2016 Report Share Posted January 13, 2016 The copy OKO is quite different inside, as well as a couple external differences. The proper OKO pilot and main jets are different as are their housings and don't fit the copies. I think the slide is a different size as well. The copy jets aren't numbered which is useful... OKO seem scarce in the UK at the moment, very rarely for sale on ebay, I have never tried OKO UK. They work well though, I have them on some bikes.

scot taco Posted January 13, 2016 Report Share Posted January 13, 2016 Try Mid-Atlantic trials.com.He is the guy to go to here in the US for OKO carbs.It may be that shipping cost are too high,but worth a look. Quote Link to comment Share on other sites More sharing options...
