No it won't, but he may get info faster that way! :msp_wink:

Anyway, that 61 is a very early one - so it definately needs a larger carb than it came with, in addition to the top end and intake. Then there is the question of mounting a suitable top cover, or modify the original.

Keep in mind that I am no expert on this, there are others on here that know more about it.

Mine has a 266 topend on it.

The early 266s had the same small carb as the early 61, before they got a larger one around 1985 (rated power output increased a little). The 61 eventually also got a larger one, but that was much later.

Niko do you know what the # on the carb is?

The early carb was the HS-163, the later one on the 266 HS-224. The later one on the 61 was the HS-254 (from 1991). Regarding 268/272, most used the HS-260, but a the earliest ones had the HS-234.

All those carbs have a 17.5 mm verturi, except the HS-163, that is smaller.
I don't know all the differenses between the other carbs, but at least some of it has to do with the intake/impulse style.

Just checked mine the verturi on mine is 18mm.

Btw, the HS-163 is (nominally) only 15.9 mm, so this isn't about a minor difference.
