Clearly sounds like you are too rich.....especially since we have DS guys posting much less #'s on the mains. Running a 210 and going to 175 is a monstrous jump. Get together with your bud, you guys keep racing while you are going down on the main (from 210). When you fare the best against your bud, you have achieved your best jetting for your main. Try to stay as high as possible on the main without loosing performance.

 

DO that and you may be posting next week in the Yamaha forum asking for help for your Raptor buds. hehe.

 

I asked three of my friends to check there diaphram and all three had the same wear spot!!It's just a matter of time before they also get a hole in there diaphram.I have not checked my baja yet but im assuming it will do the same since they both have the same carb.

 

Anyone interested in PINEWOOD DERBY stuff??!!!

I'm selling off my entire stock in ONE auction on eBay. Over $400.00 of pinewood derby cars, equipment, hop-ups, etc... and the auction starts at $1.00. (I know- I'm crazy).
