Torque Ring

[rmacdona]

Has anyone ever used a Torque Ring (like the one on FRP website), what did you experience?

 

[2 B]

I just got one too. Have not used it yet. I'am trying to calm the hit with the rev pipe by adding this feature. Don't know till I try it.

Let us know, I'm keen to try one out.

I bought one from Fredette a couple weeks ago...It was fantastic! Significantly increased my low end on my 91 KDX.

I wonder if it will have the same efect on my 98 220 as too your 200?

 

[rmacdona]

2B, I will let you know (I ordered mine on Thursday for my 2002 220r).
mrmodine, did you lose much top end?

[mrmodine]

No discernable difference on the top end for me...I would recommend just calling Jeff Fredette and asking him what he thinks for your bike. He won't lie to you... Besides, it was like 10 bucks or something...my last fall cost more than that. Good Luck!

Just rode with ring in, helps bottom didn't seem to effect top (runs out of breath in about the same place). best $10 bucks I ever spent. I just slid it in (took 10 minutes), should I have used some kind silicone? Doesn't seem to leak exhaust at all. This is the best bush bike I have ever ridden.

I bought my prevoius KDX with a torque ring installed, but removed it later on. I did not experience any difference what so ever.

I made my own and did the first test ride last night at home. My perception is that it noticeably improved the bottom end, i.e. I'm pretty sure it's not a placebo effect. It seemed to require a softer touch on the throttle coming out of slow turns because it really wanted to lift the front end as soon as I turned the loud handle. I didn't notice a loss of top end.

First impression: well worth the effort. :aj:

Barry what did you make your own out of? just washers? what size works best and how many?

[fatty_k]

Yes, please do tell!!
Also Barry, did you do this to a 200 or 220?

 

[BarryW]

I used round aluminum bar stock and cut it on a lathe. For my '90 model (200cc), the dims were ID=1.500, OD=1.800, thickness <0.215. Someone on another thread mentioned putting an extra gasket or two in the head. I'm not sure what year model they had, but mine uses o-rings around the pipe to seal, not the ring-type gaskets. Installing the spacer required removal of the outboard o-ring because its groove was pushed outside the seal bore of the head.

 

[fatty_k]

My 98 220 has two rubber o-rings around the pipe and a copper ring gasket that goes around the face of the pipe and exhaust port.

Did you get these dimensions off another torque ring or did you come up with these numbers by your own measurements?

I came up with them myself.
