occasionally (probably once or twice during a riding trip...) my ds will just die.... i think its usually at idle or really low throttle.... then the tach jumps to 10k (engine dosnt rev) and tach will stick.... i then cant start it until i turn key off, and back on....but then it starts/runs fine....

anyone know what it is?

also, i KNOW im running lean on idle circuit.... (i cant locate a new pilot jet...so for now im just like 3 1/4 turns out on fuel screw...) but i still get considerable black smoke upon start up (my discs and my grab bar have black soot on them....which would indicate rich condition...) any ideas?

 

nobody knows.....the trouble ive seen.....the trouble ive seen.....

nobody? lol

 

Oh well.

 

well...i bought a dynojet kit.... and had it jetted for my mbrp pipe (with a 185 main) and i used the new dyno needle as well...

im now running a WB pipe with a 175 main (still messing with jetting a little bit...) needle at 2nd position from the TOP, stock pilot (im lean on the idle circuit, but cant find a pilot jet one size larger anywhere.....) so for now im at like 3 1/4 turns out on the fuel screw....

the main jet in there now came from my shop...so i dont know if its mikuni or not (im assuming it is...)

what is the difference between mikuni numbers and dyno numbers?

 

So much for all that stuff I typed.

 

what is your elevation? im only at 700 ft above sea level.....

 

Ditto.

 

air box lid? tubes in or out?

For a given number, say #175, a dynojet jet is much smaller than a mikuni jet, thus less fuel flow.

You can tell a mikuni jet by the "R" and the Mikuni symbol on top which looks like a square with another small square in the lower left corner.

The dynojet is has a longer head and no symbols

lid on, tubes stock location KN w/outerwear In airbox

ill have to pop it open to see what it is.... anyone know where i can get a new pilot? none of the local dealers carry them

 

hmm never really considered that....

i beleive its only happened like 4 times.... (througout the total of maybe 50 hours i have on the quad....)
