Hey guys just had a question for you guys, I will list my current setup and if you guys could let me know some cheap or free mods I can do I would really appreciate it.
2002 400EX
Stock Bore ( I think, bought it used )
Choke removed
42 pilot 152 main
uni foam filter, cleaned and oiled
White Bros E-Series
New spark plug
outerwear over snorkel end
Airlid still on.
This is what I have done in the last week,
Ordered Sparks Timing Advance Key ( will be in on thursday)
Removed Choke
Jetted 42 pilot
jetted 152 main, went with a 155 first and it was too rich.
I removed my air lid yesterday and tried it with the 152 main it was too lean as it would run without popping but had no power, it was pretty loud under the seat area too, I know this is the intake noise but is it usually VERY loud? Also what do you recommend for jetting to remove my airlid with my current setup or is just drilling holes and putting pre filters in the holes a better option?
I also did a rebuild kit with all the moving parts and gaskets this week, the parts in the carb were not worn excessively but definitely showed some wear and tear, if you have not rebuilt yours you should get a repair manual and rebuild that sucker, it was very easy and I found that most of my gaskets and o-rings were either flat or cracked which can result in air leaks or bad performance, the rebuild kit was from the dealer and it was 19 bucks out the door
Ok guys whats your ideas for cheap or free mods that I have not yet thought of?
