TMX 35 or OKO 28 on ts1

[boxofbits]

I've been using the pwk on my ts1 for some time now with a jl3 - works quite well -but would the tmx 35 do any thing more than the 28 any one used both!

Both the Mikuni TMX and the Keihin PWK are excellent carburetors. Whichever you choose, get the genuine carburettor and avoid copies. Mikuni's and Keihin's machining and manufacturing tolerances are second to none.

Don't know what "28" you are running. But the TMX 35 is a very responsive carburetor, especially for its size (once dialed in of course). I don't know if you're using a Mikuni TM 28, but I haven't heard of many tuned scooter owners using this carb. I've used the TM 32 and TM34 on tuned scooters (TS1 and Malossi 210) and looking back I think I might prefer the old flat slide TM34, at least for extended motorway use. Never had an issue of leaning out (though that was on my P210) but my mate Dean(speed) preferred the TM34 over the TMX 35, I think because of this reason (and the fixed needle jet as opposed to the different needle jets available for the TM series).

That said, I like the Mikuni TMX 35's on both my TS1's, one with a JL4 (full "race" exhaust) and one with a DevTour.

I'll disagree with that last bit. Some of the larger/newer Keihin PWK airstriker and PWM carbs are nice but the 28 is quite old and I would say the quality on the BGM PWK is far superior to the Keihin in this case.

The TMX pairs quite well with the TS1 - others do as well but main advantage there is the wealth of jetting info since it so commonly used.

yes it was a oko copy one from nam all the jets i chucked and started with proper branded ones had to do mods on it also but to stop fuel starvation but fixed and it ran ok on my ts1 but going to give tmx 35 a go and see if i get any improvement

I stand corrected. What I get for spouting off when I haven't used a Keihin as the Mikuni TMX, as Mark says, works really well with the TS1. The SoCal TS1 boys were all using these back in the mid 90's.

The TMX also fits inside the panels of a Lambretta better than many other carbs, 'though it is a bit tall and may hit your floorboards if you ride on potholed roads.

Cool, eden. Better fitting is definitely a good thing. Are they easy to jet with TS1 kits?

Matter of fact, I remember in the '90's many of the dirt bike racers were switching to Keihins.

If I get one I'd do the same, direct from Sudco and only genuine Keihin, no copies.

thanks for all your replys but , this is no 'airstriker' ive got but just looked them up they look very good woundnt mind one of them -Mine just a standard oko 28 mm copy - must be 7 -8 years old now

That was my experience of OKO as well. Lots of faffing about with the float and other bits to get it to work.

both the tmx and the airstriker carbs are made by the same company, Sudco and if ordered from the USA are about the sane price.

Sudco doesn't make anything. They're merely a distributor for Mikuni and Keihin in the USA. They'll sell direct but you'll be paying the highest retail price for them.
