Setup stx-r for stock N/A
I have bought me a second stx-r, my first is a limited setup stx-r.
I compete in stock n/a class and we are follow ijsba rulebook. So i race mostly against stx 15f. I need to be faster than those 4 stroke.
What mods can i do to engine, cooling water, carbs etc...
Handling mods, the only mods that are is beachhouse spons.
It would be fun to smoke some 4 stroke...

Stock plate.....15F exit nozzle...2mm bigger stock prop works pretty good. Some other tricks that are not really legal but not illegal ethier...Well depends I have not read the book in a long time...lol
Your lighter so getting off the line is not a problem.
What are they aloud to run>> in the 15Fs'

I think they are allow to do about same mod on four/two-stroke.
Rouge Big airfilter+catchcan
Ada advance timing 5 degre
Solas mod impeller done by Impros
Mod intake grate
Mod cooling water
is there any profit to take away choke and change airfilter mount advance timing, etc..on the stx-r?

NO way to advance advance timing on stxr but yea the flame arreestors and choke remove will help a little.
I would run your factory pipe CDI in there to with 91 octane. If they can run the timing advance yu should be able to run a ignition. Thats like a double standard which is crap.
Run the cdi with out the white plug. Which means you have to run the temp sensor off the pipe disconnected along with the air temp sensor.

Hi, i read abour your stinger mod whith the jetworx exhaust valve in your project thread , did it gain anything?
I was out yesterday with my stock stx-r an it was doing 60,6 mp/h on the gps. only mod is r&d plate, greate and beachhouse spons.
I will do some more test whith a skat trak 13/19 swirl this weekend. Do you know any more stock legal tricks that works?
