You bet my friend and I am really glad to hear that. Wow you know we really should plan a get together some time with all us Magnum owners (and 150's). I could load Mike's up on my trailer and haul us somewhere close to some of you guys. Maybe do a campout with a "liars" campfire or something. Sure would be fun!

Great Ger.... just ride as you feel like and rest the same way....Yes Ger your right I need take some pictures as I made a few changes just this week with some real small door gasket material for the glove boxes that worked so good I pulled the front V nose section and used it there and wow what a nice fit. The color is brown but even looks good with silver.

Mike I thought you had already done that?? Did you use some different type of material than what you had before??

[mike6736]

Lee yes the material is different and I will post pitcures later when I will also post pictures on the hub Mods I am gong to do. I also used the material on my after market trunk on the rear of the Honda Reflex and may use on the new wind shield for the when I get the larger one. I stil have to take it easy for a few more weeks the Doc says so when I can I will get the magnum in the air and pulll the deck and get the hubs mod done and no more play/movement in the wheels. Also amd going to do more under glass work on the deck, I think that is the reason they now have that metal web added on the new ones. I am now have a crack/split over one fender were I did not web and glass underside. May over lay the whole deck with 2 layers of glass and PVC than have it painted.

Update

Here is the information I got today from Ice Bear.

The owner did get to ride one of the modified Magnums and said the ride is better and the vibration has been cut down quite a bit. However, Because of being a single cylinder engine there is still going to be a vibration at an idle. That is just the nature of the beast.

1. The frame design is different. It's more complicated than before, 2-3 times more complicated. The purpose is to minimum vibration.


2. They added more cushion on the bike. But he didn't specify where. Assuming the seat.


3. They used the dual exhaust system. According to them, it helped greatly with the vibration. However, we're confirming on our end to see if EPA is going to be ok with this design change. This is a working one into two design, not a "Dummy" dual exhaust.


The next shipment of 300cc will be the Magnums. I don't have the ETA yet. Manufacturer needs more time to upgrade the Tornado and Compeller.

Still do not know if there will be a price increase either. Plus the EPA has to approve the exhaust design.

More as it becomes available.

So I guess the Tornando and Compeller will be awhile till they get updated. A padded seat, dual exhaust and frame change. 2 to 3 times more comlicated then before can't wait to see what they did there. Still going with a chain Jim or don't know.

Still chain final drive as far as I know

Hello Jim
what you have said you have dual exhaust do not see it being a single cylinder also logical if you look at this photo
icebearatv.com/upfiles/13312713745.jpg
taken from behind looks like the exhaust exits through the right side next to the wheel or the right of the two tubes looks like a trim

I also questioned that but, think of it as a car that has a single exhaust pipe running back and splits off into 2 mufflers.

The picture you show is for the Zodiac. Not sure how they will do it on the Magnums.

I don't know how dual exhaust will help with the vibration. Can someone explaine that to me?
Also I heard that the engine has a lot of vibration has anyone tried balance maybe the flywheel or welding a damper from engine to frame? We used a little looked like a shock on some cars that had vibrations for motor mounts, just a idea.

[rapidjim]

The 300cc trikes are a single cylinder machine and have vibration, more at an idle then driving down the road. That is the nature of the beast.

Now I am no expert on exhaust on small displacement engines but, from what I have been told and read, by going to a split exhaust allows the exhaust to get out of the motor faster yet maintaining some back pressure will help with engine vibration, also will yield a small gain in performance. The trick is balance between back pressure and free flow. Very similar to the theory behind an exhaust balance tube used on big twin motors.

Now I may be wrong here, I am not a designer or engineer, but in theory it should work.

Maybe someone with more single lung motor exhaust experience will chime in.

Jim then why the 150cc single cylinder does not have as much vibration,is it because it is smaller? What you think of the balance the fly wheel? A dealer told me that when they copied the engine the degree of the cylinder is not the same as the orignal one they copied and that is why it has so much vibration. The proof would be to see and run a Real Lindai from Yamaha and see if it vibrates as much. Have you every worked on the real deal?

I assume it is because it is larger. I am not sure that balancing the flywheel would help but, it could and I would assume because of machine work costs it would not be cheap.

The dealer you talked to could be right then again the Chinese Linhai is copied from the old Yamaha design and he could be wrong.

I have not had the pleasure to work on a Yamaha Linhai.

All I can say at this point is a wait and see if the improvements will meet the consumers satisfactions. Frankly, with a large displacement single bore you will get vibration, plain and simple. Not all of the vibration issues that people have are connected to the engine. If it is to much for your tastes then I would recommend you buy something else. I would really love to own a Harley trike but sadly that is way out of my price range. Now my sister has a Harley that was converted to a trike ( real conversion not training wheels) and she has vibrations at an idle also and she just loves it.

Jim I had a 1969 Sporty and it had a lot of vibration. Does the Icebear have more then that?
The Harley didn't bother me. I keep thinking out attaching a damper of some type. On my Bow and arrow I have in the front of the bow a damper and it helps with the torque or vibration when shooting it. Its small maybe 6" could attach it to engine. At Chrysler we had gel filled motor mounts and vibration mounts. Is the camber and caster, toe-in adjustable on the 300?
We also had bad vibration on the mini vans due to the axle shafts being jammed (not centerd)into the transaxle to far, all it took was a big pry bar to move it a little one way or another, Just thinking out loud. The 400cc Bergman is a single why does it not vibrate like the 300? Could it be because of the fuel injection?
Got to be a way to fix it I don't think it's got anything to do with the tryke rear section. Now if I only had a bike to work on it.

Update!

The EPA has passed the new upgraded Magnum!

Ice Bear (China) is now in the process of getting and installing the Emission Data Plates and Safety Data Plates.

ETA to the US is still middle of July.
