I went to a BR8HS and that helped with the heat a little. I've also changed the timing a little and i'm going to play with it some more as I think this is where part of my problem lies.

I definitely need to get my carb tuned right and I'm getting closer. This is always a bit of a process and i know I'll get it. I'm currently at an 88 main jet and it seems like it's doing well at WOT. I think i just need to mess with the needle a bit to get it perfect.

Either way, I've got some questions for anyone who's ran this parmakit CDI box. I hooked it up to a timing light and it is definitely retarding as RPMs increase. I know it's supposed to do that but I now have confirmation that the box is actually working.

I currently have it set just slightly more advanced than the most advanced timing mark on the Tomos cases. When RPM's increase it buries the firing mark past the most retarded timing mark on the case. When I first made this post I had the stator literally as advanced as it would allow me to. Even when it was set there it would move the firing mark past both timing marks on the case.

So how far will this box actually retard timing?

Do I still want it to be firing within the two timing marks on the tomos case while I'm at higher RPMs? It seems like I would but maybe I'm wrong.

I've heard of people using a dremel in order to be able to advance timing even further on a tomos stator when using this CDI box. Is this something I should consider?

I know I don't want it to be firing after it reaches tdc. I'll need to hook up the timing light again and make sure that isn't the case. I'm currently waiting on a new choke for my carb because it came unthreaded while I was riding monday night and I lost it to the road. So I can't ride until I get that part from treats later this week. In the meantime I'm just trying to get a better understanding of this CDI box.

So I'm curious how other people have set up this box when running it on a Tomos. I'm getting closer but this is the first time I've ran a box with a curve. I read in the wiki that some boxes will have an initial advance at idle and then start retarding as RPMs increase. Is the parmakit one of these boxes?

If anyone has any info on the curve of this box it would be greatly appreciated.

Links to other threads related to said box would also be good.

Sorry I can't be more specific with the timing. I need to buy a new micrometer and until then I won't be able to know exactly how many mm btdc it's firing.
