Jim, they seem like reasonable prices to me. I use a Hyundai
6.5hp electric start engine in my generator and it has worked
perfectly without any issues. Mine even has a remote control
start which would be a bit Buck Rogers on a CK.

Gemini usually include VAT, but not delivery.
JimR, are you going to comment about 212 con rods as on the US
site?

Jim - good point just checked Gemini and £181 becomes £233 with
VAT and Delivery - so good deal on Hyundai site. Ian

I did comment about the reasons that they may be failing, as the
post was about failing con rods, personally I think that it is
probably down to too much tuning on an engine that was designed
for less power. The poster seemed intent on fixing the problem
with billet con rods. That just moves the problem of too much
power to the next weakest component. We add a bit to the 6.5 -
7.5 HP standard tune in the U.K. but the 10 HP we limit
ourselves to, which is sensible as these things are basically
works of art with an engine for fun and enjoyment of both the
driver and the onlooker, is probably not going to threaten the
engine too seriously unless the work done to it is not done
carefully.
The road to horsepower series of videos by Redbeards garage I
linked to earlier has moved way beyond our needs now but I still
follow it. The last video I watched in this series had the motor
at about 17HP and it broke. It is notable from that series that
the gains to achieve 10HP were mostly done by simple mods namely
governor removal, 18LB valve springs and a new carb. All these
mods can be easily transferred to a new, cheap, engine should
the worst happen and we have failure. I think I would prefer
looking at our 10HP limit in terms of usability (wider power
band/ low end torque) and reliability and design mods around
those criteria.
I think that thread in the U.S. has gone quiet now Rhys.

I actually believe that the UK limit takes it further than the
US approved Stage 1, certainly many of what I saw at Stretton
would be quietly discussed with the owner at events I went to.
Driving here with many is more frisky too. Maybe the short
circuits here which don't support the sustained higher revs seen
at most events in the US is worth the thought.
I think the thread went quiet for a number of reasons. One being
Denny, another reason the promotion of something that costs them
more than a replacement engine.

Rhys, agreed. But now Denny is setting traps over there by
showing monster bored out 212 cc things to 263cc and saying that
is he wasn't retired and had the desire he would have a go at
it!
". I know I would if it weren't that I'm a long time retired guy
who tain't got the geedis now a days.

A man of contradictions, as we all are.
My point was about reliability. I will say that as many times as
I can. If you add a component that costs, at most a hundred
bucks plus postage - eighty bucks the numerous times he has a
sale during the year I have been watching him and it saves you
buying one billet con rod, let alone all the other components
you have to use to get your engine to such power as to muller
two con rods in the first place and whatever else you might
damage along the way, is it a false economy not to have one?
An example. A highly tuned but unreliable vehicle is fast for
three laps then stops for tinkering or goes back on the trailer.
This happens quite a bit. Some people travel great distances to
attend events, even pay for hotels to stop over, track fees,
fuel, food out, (BEER ;D ) What price reliability? One meet
like that and I would burn through more than a hundred bucks
with a bad taste in my mouth and be no wiser with a list of jobs
to do in the garage when I got home.
Most of our received wisdom on engine tuning is from the kart
scene. Small wheels, light karts, high revving engines with many
rules of what you can and cannot do to them. It has become
prescribed and set due to rules. Kart tuners use these rules to
wring the most out of the engines within the rules and the life
of these engines is measured in hours with an engine not
reaching its full potential for a few hours then lasting a
season and getting worse or breaking.
I argue that perhaps, given the only rule we have is 10hp max
-again, a sensible rule that ensures we can insure them and be
relatively safe, keep the hobby accessible to new entrants and
stop an arms race of bought components that can easily triple
the price of an engine whilst making it less reliable- We should
look to reliability and the fun we can have within the power we
are allowed. I would not like to utilise all 10hp around a tight
and twisty track in a three wheeler and didn't- The goal should
be to broaden the power band to stop machines bogging down in
the corners as much, keeping the machines drive-able, whilst
building for reliability so we get to enjoy many laps.
If I have achieved this I am not sure yet but that is my aim it
could still prove unreliable or unsuited. (Notice how I have not
yet published my findings so far on the CDI thread I started?) I
am, like most of us, a tinkerer. If I fail I try again. I first
had the idea looking at what the vintage motorcycle people do to
make their bikes a little less likely to snap your leg on
starting and be more reliable - hence the CDI kit- Since putting
it on, I have also looked at how to knit one out of bits cheaply
available off the internet that might, if it works, get the
price down to about £30. (two rounds of drinks for four up
north, bloody expensive!).
I hope that fully explains my thought on this Rhys. It is not
intended as an arms race for speed or power. It is intended to
keep the cyclekart usable and reliable. If it does not do these
things I will bin the idea as, as yet, it is an experiment.
