Woot! First one posting again! Lol.
I've been running a Mikuni TM series flat-silde carburetor on my Blaster for the last month, and since most people here run Keihin's, I figured I'd review my Mikuni for those who might want to try and run one.
Carb is well-built, and the price was decent at around $ 150.00 brand-new. It uses a mechanical idle-speed adjuster, which is great. Its just a tapered bolt which holds the throttle slide up. No funky airscrew idle adjustment like the OKO 30mm's use.
The carb bolts right up to the engine, but you will need a reed spacer to get the carburetor to clear the clutch arm. I also had to grind down the carburetor's casting to get it to clear the lower left intake boot bolt. Not hard to do, but necessary.
It comes stock with a plastic slide , but so far I haven't had issues with it. The stock 5fp17, double-tapered needle is too rich for the Blaster engine. I am still in the process of tuning to find out which needle works best on my setup.
The carb has a very stiff throttle return spring. I cut a couple coils out of mine to ease the stress on my thumb while out riding. Any aftermarket throttle cable will work with this carb.
I'm running a 290 main and a 35 pilot as of now. The engine likes the main jet, but the pilot needs reduced one size. I'm still tuning. It is snappy in throttle response and easy to work on. The float bowl comes right off; no hassles like with the OKO's and some of the Keihins. It also has a plug in the bottom of the bowl, which you can remove to change the main jet without pulling the bowl off.
Overall, this carb is a nice upgrade over stock for a ported engine like mine, but it is difficult to tune since I am one of the only ones on here running one. Its a lot of trial and error. I like this carb and will recommend it to anyone, but we've got some researching ahead of us when it comes to tuning.
