Hi Gary,

I have some of your videos but I was wondering, since the fourstrokes came out, do some of your instructional techniques change to reflect the different handling and behavioral tendencies of thumpers?Just something I have noticed as my riding has improved(thanks to your practice manual) and I have to give advice to some newer riders. Thanks. :cry:

The techniques between 2 and 4 strokes really haven't changed very much. Following are the only changes and as you read them you'll understand that they are not really changes but adjustments.

Ever since sometime in the early 80s two strokes have put to good use the development of a power valve in the exhaust port. This power valve has smoothed out the hit of the two stroke’s power band a great deal. But in order to get a lot of horsepower out of that two stoke engine they still have a certain amount of hit to the power band. This is the biggest difference between the two and four stroke. The four stroke is just smooth tractor like power right off idle all the way upstairs. This is why the four strokes depend less on the clutch and more on throttle control. You don’t have to help it into the power with the clutch nearly as much as with the two strokes.

The other difference is with engine braking. When you’re going down a straight away and you shut off the throttle on a two stroke the back pressure from the engine will slow you down a little, but on the four stroke this engine braking is much stronger. This will make the Exit Dex of a corner (where you go from braking to accelerating) easier. You don’t have to be quite as precise with the brakes. This engine braking effect will affect you on jumps too because if you roll the throttle off on the take off of a jump it will throw the front end down much more on a four stroke. This won’t be as noticeable if you’re in a higher gear.

Since you don’t have to be as precise with the clutch and throttle and the brakes on a 4 stroke they are easier to ride.

At this point in time that’s the only differences when it comes to rider techniques. The way I see it it’s all good.

:cry:

I would recommend one of my two day group classes for you. There's a lot of hands on training and everyone has a lot of fun learning the proper riding techniques. You can check out the schedule on the GS 2005 Schedule page of my web site (www.garysemics.com).
