Bottom and top end wise? I do have Picco .12 JL Tuned for my tourer and its the best bang for the buck eng i have ever bought and thats also the reason i wanted to try the .21 version of it for my 8th scale onroad. Sorry for the long q's i just want to make sure i make the right choice and not regretting it later on.
1) These engines are fast, watch for the rear bearing going out. TKO bearings work really well and are priced just right. The only problem they have is with the carbs. Replace conrod after break in and then usually every 2 gallons (or whenever you see play in the conrod).
2) As I said, the carbs are sometimes problematic on these motors especially on the bottom end, but look at the IDM engines thread they explain how you seal the needles (IDM motors use the same carb).
3)Piccos are worth the money, novas are expensive. If you can pay a little extra the IDM is a very good choice. They are easier to break in than the novas also.
Best bang for your buck IDM Evo3 (based off Picco Evo3), it's fast as hell, great motor! Don't get me wrong though you can't go wrong with the Picco either, just depends on your budget!
