Title: Hesitation, starting out.
Post by: ryjb on August 07, 2010, 02:38:40 PM
I have noticed a few things on my Magna that have slowly crept up on me.  When riding down the street I will notice the bike will have a slight hesitation from time to time.  This is happening when I am keeping my speed and RPM fairly constant.  Almost has the "out of fuel" feel to it.

Also one more thing.  When in 1st gear and letting out the clutch I am having to give it more throttle to get rolling.  Just wanted to see if anyone has any ideas. 

Thanks

Has your carbs had the shims installed on the needles?  When riding along on a stock Magna around 3500prm range you will feel this and the shims will take care of it.

As far as the power increase on bottom you might adjust your clutch.

+1.

Mine does this, too, Ryan. It is a "feature" of Honda's having to run the engine lean in that RPM region to meet emissions requirements. I need to shim mine also.

I knew I was not alone. :) I do have the Dave Dodge shims sitting out in my garage.  I was planning on working on the carbs when winter rolls around.  I am sure I will have questions then.  Thanks

There are instructions on how to do this on this site.. The only think I would add to those instructions is it tells you to push on the needle to unseat it.. I do not recommend this as you could bend the needle. There is a thread hole on the back side, take one of the screws that hold the cover for the needles and screw it into the back of the needle and pull.

I did the shimming without removing the carbs, but it is about as easy just to pull the carbs.
The shimming did help the hesitation some (added one shim).
I put in 105 mains and it helped even more and I plan to go to 42 pilot jets and I think that will fully resolve all hesitation.. (NOTE: I do have a couple of holes drilled in my end plates of the exhaust which leans things out even more)..

I agree Hoot that to thread a screw into the rear of the needle holder.  HOWEVER I have removed hundreds of needles with my fingers gently pushing them out without (knocking on wood) a single bent needle.
