We have special clutch springs that can lower the engagement speed. How many teeth on the rear sprocket?
Lee,
The sprocket has 64 teeth.

Hi Rob,
The testing and research on the flex pipe was conducted on several different DYNOs and the data varied greatly. In all cases the flex pipe indicated an increase of 18% or more HP, and the torque peak was also slightly higher. The most important information gathered was the torque curve had relocated it's peak about 600 RPMs lower [slightly more bottom end grunt].
One motor tested [Honda GXH50] went from 1.90 HP to 2.45 HP with the pipe exchange. The motor had the original "box" type muffler and then the tuned flex pipe.
The data isn't on the EZM site because EZM didn't conduct the tests [I did] and it certainly won't pass EPA standards. The flex pipe kit isn't actually available from EZM,
but from Simpson Motorbikes, or myself.
It is also important to note the design helps reduce the noise as well as supply the necessary back pressure for good overall performance. It is louder than the "box" or kit pipe, but not as loud as you would expect. Nothing like the pipes on a HD or any straight pipe. Most think it has a nice low mellow tone and most like the ease of installation and the increase in power.
Hope I answered your questions,
Have fun,
Quenton
Really? EZM and yourself are different and separate entities?
You should be in politics LOL
I really like the flex exhaust too on the 4 stroke motors but a
correctly designed and sized smooth hard pipe would make a little
more power than any kind of flex tubing.
The most "special" feature of the flex pipe that EZM sold / dumped on
its customers was that it blues and tarnishes very fast as it is not the
good stainless flex that I would recommend.
Your Woodland Hills EZ dealer was not very happy with the inferior flex
pipe that you sold him although it did match the very pretty blue paint
on his gorgeous Felt EZ build.
Flex man also mentioned that the ID of the flex pipe was too large to be
clamped to the 7/8" OD stub from the carp pipe that comes with the EZ kit
I am building a 4 stroke in frame bike using a 50 cc HuaSheng motor.
I like the way the 4 strokes run and sound.
Looking forward to everyones input and ideas.
Thank you!For someone who seemed so "new" you seem to be very opinionated about things. I will be here to help you out if you have any questions.
Kline's Kustoms 50 Honda with the # ! production Q Matic with a 56 toothYes, this is beginning to sound like the Forbisher of old, carping about things without having all the facts. By the way, I have a non-stainless flex pipe on my bike, and yes, it has the patina. Actually, I like the patina. As to it fitting on the stub, no it will not fit like a piece of (to use an analogy from my line of work) pond tubing onto the tubing adaptor (in other words, a tight fit). The best way to secure it is to use a 1" seat tube clamp, as I did on mine.
Also, my 49cc HuaSheng with Q-Matic and a 64-tooth sprocket has seen 40mph, so the performance bump is substantial with the correct size and type of flex tubing.
OOooppps, a little mistake there LOL
8600 would be needed to go 40 mph on your gearing setup if you have a
2" to a 5" pulley in your q matic.
That is not hard to do as the Huasheng motors love to rev.
Just don't do it for too long or you may Blow By U your motor.
Try hitting 40 mph with a 56 tooth and ape hangers. that is a lot harder.
KilroyCD, your bike looks great.
