The other day I was driving down the road and my 450 peaked out at 47 mph (with 26" tires) I noticed that every time I hit 47 it would slow down to 45 and creep its way back up again and the process would repeat.

This could only mean one thing, a rev-limiter. I looked in the shop manual and saw the schematic diagram for the ignition system but could not determine which wire was the feed back loop to ground.

Has anybody figured this one out yet? It seems that these 450's run anywhere between 46 and 51 mph. ( I just want to run on the upper end of the range) Don't you just hate it when you get "dusted" by old Polaris 250 and 300 model beaters?

 

I personly have no idea where the limiter is, I just figured that the coil was programed to fail. I wouldnt push that engine to far, as it is a Pushrod design..

 

Where did you get the shop manual? Is it for the 450 or 400?

Jaybird, you can get the manual from Honda. Check out their website.

 

Surely somebody must have an idea as to how to defeat this system.

 

I already have the service manual but it is not clear which circuit wire needs to be clipped.

 

Doesn't look like anybody ever figured it out.

Have all of the innovation pioneers left the forum?

Maybe the White Brothers have a cure.
