64 tooth working out well!

[48rob]

We have special clutch springs that can lower the engagement speed. How many teeth on the rear sprocket?

Lee,

The sprocket has 64 teeth.

Sorry been so busy I didn't take the time to read earlier posts or I wouldn't have asked the sprocket size....DUH

Special spring will engage clutch sooner. We only have a couple of springs in stock, as it is no longer mfg by Max Torque. The range from idle to "ticking" speed is reduced and may require a different idle setting.

I think several of our dealers have installed the special spring to allow riding at super low speeds. Maybe they might comment on the differences between the stock EZM clutch and the modified spring version. Not sure but I think AZBill might have tryed the special spring on his stretch and possibly RdKryton tested it on his HF 79 CC build using the Q-Matic drive.



Have fun,

Thank you!

I understand busy, not to worry, I just appreciate the fact that you and others have any time at all to answer questions.

I look forward to hearing from the other dealers, sounds like what I'm after!

Vendor Questions?

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

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

Hi BiMoPed,

As always we are treated to your "negative" comments. Too bad you often don't have a clue to what EZM is testing, designing, producing, or selling, nor do you know my daily routine. We [Mike Simpson & myself] have offered both Standard & Stainless Steel flex pipe kits for some time now, in fact I shipped out both version this morning.

The vast majority purchase the standard version because of cost, and consider the "bluing" of the pipe "patina". I still have the original version on my test bike and have way over 5000 miles, true it has discolored [like 99% of all motorcycle pipes] near the exhaust manifold, but still maintains the "vintage" look.

Vintage Whizzers used the standard flex pipe, and managed to live with the results [over 200,000 of them sold]. On certain Whizzer "J" kits the pipe was chrome, and quickly discolored, but no one complained.

You comment that our Dealer in Woodland Hills, CA was not happy with the pipe.......He didn't mention it to me, and he certainly has the option to purchase the more expensive pipe if he wants.

I find your negative comments about "dumping" the flex pipe kit, typical coming from you. I also find it interesting, not a single person has asked to "exchange”, "warranty", or "return" any of the several hundred flex pipe kits I have supplied.

Now I will see just how knowledgeable you really are............Are the standard and the stainless steel version of the pipe the same I.D. size? Do both versions of the pipe test the same? What is the correct I.D. and length for the HS or Honda motor? What is the correct length for the HF 79 CC 4-stroke motor? What is the correct I.D. and length for the Whizzer 138 CC flat head motor?

Which produces more bottom end torque........ Small I.D. long pipe?.........large I.D. long pipe?.......small I.D. short pipe?........large I.D. short pipe? Does the tip make a difference? Do different style of tips produce different results?

I do know the answers to all the questions, as we did a major amount of actual testing on both Dynos & "Roller Roads".

Please treat us to your knowledge, including Dyno, Roller Road, or actual field tests. Can your test bike stay up with the current version of the EZM kit [Do you own a test bike]?

Do you sell your "tested" version of the Flex Pipe Kit? If so, how much? Please save us from the evil pipe monster.

Have fun,

Yes, 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.

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.

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 tooth
sprocket was one of the fastest bikes in our El Dorado park ride even
compared to the 2 strokes.
See the pic below of Chris's stainless steel exhaust that has over 1000 miles on it.
A real GPSed 40 mph.
Chris's stainless steel flex was much longer than what Quenton says is the correct length and he had a fairly restrictive $8 Briggs lawn mower cannister muffler but his bike was much faster than the Woodland Hills EZ motorbikes
dealers bike no matter what Flex says.

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.

Thanks for the compliment on the bike. With my bulk I doubt I'd be able to get the bike up to 40mph, but a friend of mine (who is much lighter) did have it to 40 (indicated) briefly. But who says the speedometer is correct? It's a cheapy. I usually cruise at 25-30mph on it. Yesterday another friend who was riding it walked me going up a hill, and I was on my Whizzer. That 64 tooth sprocket (and the flex pipe) had a lot to do with that.
