what do you mean by (slide-type) Carb? is it like the keihin or oko 26mm carb?
keihin and oko is an example of the normal slide carbs

the normal slide carbs has a direct cable from the throttle to the carbs slide. so when you twist the throttle it lifts the slide and needle letting the gas and air through....

the other type has a rubber diaphragm at the top of the slide. and has the
butterfly throttle. and the cable is attached to the butterfly . when you twist the throttle the butterfly opens letting air in. at same time it create vacuum at the top of the rubber diaphragm and lifts the slide and needle letting the gas through....

When I looked into buying an OKO before, the manufacturer (in China) told me I needed a 28 mm. Was that wrong?

The reason I was put off getting one (I have an X1R btw) was that although the OKO comes with manual choke, there is no provision for the 2 connections (don't know what they do) which talk to the CDI.
You guys are obviously using these carburettors, so what do you do about that?
If I knew the answer to this I'd order one tomorrow at about $35, as I'm facing buying a new standard carb' at about $80-100 because I used Gasohol (Thailand).

Thanks for any information you can give me.

if you are not familiar in modifying carb and jettings
i suggest to buy the 2011 25mm yamaha mikuni carb
its plug and play for x1r/t135

TPS is builtin in the carb of 2011

Sorry, but I'm confused.

My story - I've had the X1R for 2 years and I liked it a lot but it never ran as smoothly as the Spark I had before and at times it was really rough, albeit still fast.
Recently it got worse and I took it to the shop. They said they'd cleaned the carb' but it was worse.
They said it was because I'd used Gasohol (probably true) and that I needed a new carb', but they couldn't get them as they don't stock the X1R in Thailand any more.
So I arrived on your Forum.

The part I'm confused about is that I just took the carb' off, because I had to either way and to see what I'd got and it's a round slide Mikuni (about 22-23 mm I think) - probably you knew that.
Is the 25 mm carb' you're selling definitely going to be better?

Looking in the bowl everything looks very clean to me.
I'll get the jets cleaned and try it again I suppose.
Is it possible that it's not the carb' at all do you think?
Could a faulty CDI cause the uneven running on heavy acceleration?

Thanks for any advice.

Guys, I just got my repossessed yamaha smx.. I brought it to yamaha 3s shop and found out that the carb was replaced with the old sniper carb. The mechanic told me that this carb (piston type) is way better than the current carb (diaphragm type) of smx. Is this true?
