Yes I will!

Good Job. Glad to hear it is back together. To bad your dealer didn't get the right parts to you the first time.

Let us know how it runs and if you can feel an improvement with the new bearing installed.

I tend to agree with you on the issue of putting the trike on the market to soon without extensive testing. I just became an IB dealer this year and in my opinion they have done better in this area from what I have read on previous problems. What drew me to IB was the 300cc trikes. With the 150's they admit it was a poor design, but instead of redesigning, they elected to remove the reverse gear for 2010 models. Now the 150 is light enough that reverse is not really needed. Hindsight is not always the best.

There was also a mention of warranty problems. Keep this in mind when talking about warranty issues. The warranty is only as good as the DEALER you buy from. IB does not deal directly with the end customer, that is what they rely on their dealers for. Just like Car manufactures, you deal with a dealer not the factory/distributor. We all know there is good and bad dealers out there. I personally have not had one issue with IB, including warranty parts for customers that bought their machine from another dealer. As I said in another thread, one of my first Magnums had a bent rear hub out of the crate. I called my rep and there was not one in stock in CA, however one was Fed Exed to me directly from the factory in China and they payed the shipping.

Damn I love research!!!!!!

First off lets get one thing straight before some decides to argue my figures or my definitions.. There is basically two types of horsepower, Indicated Horsepower and Brake Horsepower. Basically Indicated Horsepower is a mathematical equation that calculates, under ideal conditions, what an engine should produce for horsepower. Where, Brake Horsepower is the actual power that an engine produces, tested on a dyno. Now if an engine is built correctly and has the right compression it should produce between 80 and 88 percent of the indicated horsepower.

Indicated Horsepower can be used to draw comparisons of what percentage of power increase could be expected from increasing bore and/or stroke.

First off the formula for calculating Indicated Horsepower (IHP)

Multiply the area of the cylinder by the length of stroke in inches and that product by the number of revolutions per minute then divide by the constant 10000 for two-cycle or 13400 for four-cycle engine, the result will be the I.H.P.

Cool Huh?

IHP = ( bore(inches) * stroke (inches) * RPM ) / 13400 (4 stroke)

150cc GY6 has a piston diameter of 57.4 mm and a stroke of 58mm

First we need to convert to inches, One Inch = 0.0393700787, for our purposes we will round off to 0.03937. So, diameter of a 57.4 mm piston is 2.2598 inches and the stroke is 2.2835 inches.

Now we need to figure the bore (area) of the piston. Area = 3.14 (pi) * diameter or
Bore = 2.2598 * 3.14 or Bore = 7.0958

Now using a constant of 6500 RPM we can figure IHP

IHP = (7.0959 * 2.2835 * 6500) / 13400 or IHP of a 150cc GY6 is 7.8599 or 7.86 IHP

Using a 59mm piston

IHP = (7.2937 * 2.2835 * 6500) / 13400 = 8.08 IHP ( 2.73% gain over stock)

Using a 61 mm piston

IHP = ( 7.5409 * 2.2835 * 6500) / 13400 = 8.35 IHP ( 5.87% gain over stock)

Using a 62mm piston

IHP = ( 7.6646 * 2.2835 * 6500) / 13400 = 8.49 IHP ( 7.43% gain over stock)

Using a 63mm piston

IHP = ( 7.7882 * 2.2835 * 6500) / 13400 = 8.63 IHP ( 8.93% gain over stock)

IHP reference, Loetzer's Hand-book, 9th Edition

I will have to look around for the formula to figure displacement. I do know piston stroke is used to figure it, so if you don't know the stroke you can only get close.

The Compeller is a straight axel and to fit in the crate it has to be shipped without the wheels. I feel for your father-in-law being lied too and have to do extra work or find someone to help him. Those wheels are held on by Lug Bolts, not studs and nuts, so getting them on can be a chore for someone in there 80s.

Yep, I have heard other stories about this dealer and 3 potential customers went with them even after talking to me because they could save a few dollars. One did call me back because of a warranty issue that "they" wouldn't help with. I made one phone call to IB and the part they needed was shipped that day, took me all of 5 minutes. I just don't understand dealers like that. Tell the truth to start with and then help your customer after the sale!
