I suspect a large amount of beginners luck involved but it runs between 14 and 15:1 normally, 13:1 ish when accelerating hard and about 15.5-16 when cruising at about 110kmh. This is on my 1527cc A15 with a camtech 621 cam and 10.8: CR. I know that the Carb is the bottleneck, and i have some A14T carbs to put on it when i have time, but are there any easy mods which can be done to get more out of the stock Hitachi ? remove choke butterfly and shaft ? i never use it .. ram pipe? i have a K&N filter already Posted on: 2016/1/25 4:24
