I was just wondering if anyone out there also has the v force 2 and what setting you run on, high or low tension. Which is better?

 

My machine uses the same cage as a 250R. I run them on the high tension setting for better top end. The low tension setting is for more low to mid power. Even in the high tension setting, I still got improved midrange and throttle response over stock due to the increased reed tip area.

High tension causes the reeds to snap closed faster. Low tension allows them to open easier at low end.

I would suggest taking the cage apart, lightly sanding the edges of the reeds with very fine emery cloth as well as the cage itself. There are little dots on the cage from the mold. These dots have burrs on them which can start a crack in the reeds.

I replaced my first set of reeds due to the ovious distresses they had on them. I plan on pulling them out when I have a chance to see if getting rid of the burrs helped.

 

Is any one way better for reliability?

 

The low tension setting will make your machine run richer than the high tension setting.

There was a service bulletin about reed failures due to running lean and reccomends using the low tension setting.

This would only apply if you did not jet properly for all the mods that are made.

 

I have a 160 and a 58 at 2000 ft so I hope that is close to right.

 

I ran them on low tension and called Moto Tassinari and they say low tension unless you're running TT or long MX tracks or dunes (high end - livewire is correct). Since Livewire is correct on everything that was said, I can only add one thing. Moto T - said reeds on high tension are less than half of the life of low tension (High - replace 6 mos to 1 year, Low - replace 2 years).

 

I had my motor apart saturday trying to find the broken e-clip from my carb needle (never did find it, must have passed right through). I have a lot more hours on the set of reeds that are in it now than the first set and they hardly looked used. I believe sanding the cage helped a lot.

Interesting on the tension vs. life. I wonder whether it is directly a result of the tension, or just that the reeds open and close more in a high revving engine. I'm sure the second part is at least part of it.
