General Discussion / Re: Carb question
« on: May 23, 2017, 01:13:57 PM »
it was the float level apparently the last owner like to tinker with it, the carb bowl was filling up wayyy tooo much, so after adjusting the float it doesnt leak out the 6oclock hole ( no more drippys )

General Discussion / Carb question
« on: May 21, 2017, 10:56:09 PM »
On my 2002 cobra racer in the carb throat there are three holes in the bottom one at 4oclock one at 6oclock and one at 8oclock. When I shut the engine off gas starts running out the 6oclock hole ( the bottom one ). Do I have a bad float inlet needle?

i have a 2002 cobra racer it has a 70cc big bore kit, 94 main jet, tecnigas pipe derestricted cdi and variator , it has the stock air box with restrictor removed, the spark plug is a greyish all most tanish color at full throttle the engine buries the tac needle it pulls me uphill no problem at all ( i weigh 237lbs ) but my top speed gps is only 45mph my question is with this set up shouldnt i be hitting at least 50mph?? im not sure if my rollers are stock or not, i tried the dr pulley flat rollers 6.5 gram and then the 9.5 gram either did any good so i put the stock ones back in

« on: May 18, 2017, 01:07:19 PM »I have never 'cut' a cdi, so can't help with that. It's seems a popular mod.no my cdi was restricted i unpluged the green wire loopimg in and out of it and its running 100% better at WOT
Sounds like your engine is 'four-stroking' at wot.
Main jet is too rich, causing it to overload with fuel and only fire every other stroke.
You will need to replace the main jet with a larger number, (probably +3 or +4 from what you presently have), which will be a smaller hole in the jet.
Of course, timing and condition of the air filter should be checked, first.
redk
and i think you have it wrong the larger the number on the jet the bigger the main jet, now if your drilling them with a numbered drill bit set then the smaller the number the larger the hole

General Discussion / cdi restriction
« on: May 17, 2017, 01:57:18 PM »
on my 2002 cobra racer that i picked up not too long ago when i hit full throttle at top speed no load it will start spudering like its running rich and loose rpms if i back off the throttle just a little bit the spudering goes away and the rpms come back up a little
if im going up hill with the engine under load it doesnt spuder is this my cdi being restricted??
the color of the spark plug is a greyish it looks like its not running rich
HOW DO I DE RESTRICT MY CDI CUT IT?
