hello again
i just finished installing a new complete engine (SkyHawk) and was able to turn it on after couple seconds. i have a couple questions. before i already went to the gas station i moved the bike trying to see how the engine turns without the clutched pulled and i realized that it actually turns (with spark plug in).
means, low compression or something isnt right and there is a leak. here is the first question:
- does for you guys the engine turn even if you are not sitting on the bike without your weight?
because my old engine would never turn without my full weight and a minimum of speed. it had a really good compression and was loud as h*ll. the new one sounds like those typical motorized bikes without any power that cruise around with 15-20mph - my old engine holy **** - it had much more power and sounded almost like a 1 cylinder harley.
i also noticed that something didnt seem to work well with the carb, because it wouldnt rev up even with the clutch pulled, basically like with choke. its stuck around 3.000rpm i would guess and to get there it takes forever.
now i have two explanations.
- either there is something wrong with the compression and i dont have full compression for some reason (i can only compare to my old engine
or
- this is how the regular engines come and my old engine was taken of a big piece from the head cover to increase the compression. i also find it weird that the engine does not really rev up, only like a turtle even though the carb was set up very good before.
- the other question or favor i have is, please somebody show me a good quality image of the bottom (combustion chamber) of a regular head (not SkyHawk). that would help a lot to answer my question, because my old head doesnt have that ring standing out as the SkyHawk. on the other side the chamber seem to be bigger at my old head.
thank you guys for any input. its already 1am in the morning and i worked all day on the bike and i wont turn it on anymore but it will be interesting to see the answers.
