So I have a 2008 klx 110 mostly stock from what Im aware of besides a pipe and uni filter. Runs good tho other than it definitely needs a little carb tuning to get it to idle and get rid of the little bit low end bog. But my real issue is that it appears to have a tb head, does this mean it is a big bore ? It doesn’t seem any faster than a normal 110 which makes me think it’s still stock bore and piston but with a tb head but I can’t tell cause there’s no actual markings on the cylinder only the head with trail bikes logo. Is this possible or would the valves hit the piston? It still has a stock carb and intake manifold as well. I’m just trying to figure this out so I can get a bigger carb and the correct manifold if I have to to get it to idle and run a little better. FYI it does idle fine once it’s good and warm and I’ve been riding it for a little but even then it sometimes still likes to die. Any help or advice would be appreciated.
