Ty175 Replacement Carb

Featured Replies

What is the best bolt on replacement carb for a standard TY175 ?

A less worn TY175 carb!

Seriously though, what are you trying to achieve - more power, more low rev torque, other?

To replace worn carb and if I can get extra from it, then bonus.

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

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.

be aware a lot of oko carbs are cheap chinese copies you need one made in taiwan.i fitted a 26mm on my ty 175 with bigger airbox and birkett modded barrel plus lightened flywheel it now run great but a lot of work required.

I noticed that on the link feetupfun put up. I certainly found the irony in a company that started out copying Keihin carbs warning about cheap copies!

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...

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.

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.
