Alternative engine to the honda gx200 !!!!

Hi all so i have built my cyclekart and instaled a gy6 125cc
engine which is fitted to most cheap chineese mopeds, purely
because i had the engine !, it had its complications instaling
it, but it works, i managed a top speed of 36 mph on dirt
tracks, and its quite quick of the mark it wont spin the wheels
but not far off from doing so . I have not driven a kart with a
gx200 engine but i think the gy6 engine is an equal match !!!?.
The only issue i have is that running over rough
ground the engine starts to splutter and smoke a bit due i think
to the float shaking about causing the engine to run very rich ,
dose the honda engine have a float bowl and have the same
problem ??.

The Honda engine has a float bowl, but it's a different type of
carb, the GY6 carb has a diaphragm, and electric auto choke. I
haven't had any problems with mine, I've driven it on uneven
ground, but not at speed.

I am not sure about alternative engines being OK in a cycleKart?
I think you should check this out with Graham of Stephan. I
think we have had a similar issue a while ago and there was a
ruling made but I cannot recall the outcome.

It was mine, accepted on the grounds that at 125cc, under 10Hp,
and auto transmission it fell within the engine specs. If I
remember correctly Nic also raised the question of eligibility
before using a GY6 engine.

When the group was first set up there was a section with what
the guidelines etc and alternate engines were allowable to allow
for Chris' Morgan, and also a dispensation on width to accept a
couple of existing cars that were overwidth.
Both that and the "Ethos of a Cyclekart" seem to have gone from
the website, or at least I can't find them any more.

Well the use of a gy6 engine dose not really affect the ethos of
a cyclekart, and seeing as it is acceptable to lightly tune the
honda engine upto 10 hp which would make it faster than a gy6
engine, , its a perfect setup if your building a three wheeler.
For me the ethos and spirit of cyclekarts is keeping the
dimensions similar and the asthetics right.
