Thanks sir barurot and HKholic..classic=22mm, MX=25mm. try to check in For sale section if someone selling stock carb of MX. if you want additional performance in stock form, try to change your CDI, valve spring and rear sprocket.
Now I see.. 
Probably that's the issue why my SMX has restriction in its performance.. If I change my carb back to sniper mx stock carb, I need to change my manifold, throttle and grip.. oh my..
If you have 1 cable that enters the throttle housing on the handle bars = old. If there is 2 cables = new.
1 cable only that enters my throttle..Depends on what throttle cable you have now, but the manifold for sure have to change. Flange mount(old) vs spigot(new). +1 on checking the F/S section. Lots of people changing out carbs. I myself have 2 sitting on the shelf.
Will you sell to me your 1 of 2 sitting on the shelf? 
haha..Yeah I can sell you one, but I'm in Vietnam! Up to you bro. PM me.
try to PM kr.r_sniper maybe he can help you.1 cable only that enters my throttle..
Woah! heheheh I can't accomodate your shipping cost.. hahahaYeah I can sell you one, but I'm in Vietnam! Up to you bro. PM me.
By the way, I'm thinking to install a keihin PE26 instead of looking for a stock SMX carb but my TPS would be neglected.. You think it would give my bike an bad effect on its performance if i'll neglect the TPS?
I've used my bike with a PE28 and stock cdi before(2011 Exciter w/BS25). Couldn't really tell a huge difference in not using the TPS. Granted the cdi will not adjust itself, it's not going to hurt anything. Your fuel consumption may suffer a little. But I wouldn't let that stop me from upgrading to a bigger carb. Go for it and get a rcdi later.
Thanks sir HKholic!Can't say I blame you with the shipping.
Is your engine bore still stock on using PE28? I'm planning to buy Keihin PE26 only since I'm on stock bore.. But that TPS thing is confusing me.. What is the use of TPS? I don't get the thing they call "mapping" of cdi.. Some people says that their indicator for over heat lit up..
Nice score! No need change your throttle cable now.I just got a Keihin PE26 Japan yesterday..
yes.. yahoo!Nice score! No need change your throttle cable now.
By the way, where do we measure the size of the carb? Is it on the end mouth that would be connected to the manifold? the piston/ slide of my carb says "K30".. They say it's 30mm.. but when we measure the end mouth, it's around 26.5..
Thanks sir HKholic!Yep, the diameter is measured from the manifold side. the "K30" that you see is the slide cut away. Read as a 3.0 slide.
Since the slide is K30 or 3.0 slide, What does it means?
Not much really. It states the size of the cut-out on the slide. A 3.0 slide is standard on the PE26. Changing the slide is just another tuning option. That is, if you can find one.Thanks sir HKholic!
