lugene Posted May 28, 2013 Report Share Posted May 28, 2013 i have a 370cc (66mm) with cpi pipe ,coolhead ,ported,4 mm crank ,stock reeds,and pro design intake. the owner before let it stood for a while outside in the sun without runnin it ,it had stock pipe when a bought it and it ran great ,but just before swapping to cpi it began to run like it had dirt or something that was preventing the quad to run great. so i decided to take whole the carbs apart and make it fully clean (moved the jets ,float ,pilot etc everything apart!), i also the checked the reeds if there wasn't any tear or broken reeds and they where just fine. the compressions are good... the tube joined between the carb is there (isn't missing),made the whole thank clean for any dirt inside ,cleaned the on/off/reserve and now that i put on the cpi and it didn't show no sign of life . what could it be ? could it be the jet sizes? anything! thanks apreciated Quote Link to comment Share on other sites More sharing options...
toytech Posted May 28, 2013 Report Share Posted May 28, 2013 check for spark, then check your float level again. Quote Link to comment Share on other sites More sharing options...
oldskool Posted May 29, 2013 Report Share Posted May 29, 2013 x2 check both plugs for spark Quote Link to comment Share on other sites More sharing options...

Larry's Shee Posted May 29, 2013 Report Share Posted May 29, 2013 Have you changed any jets yet? Quote Link to comment Share on other sites More sharing options...
lugene Posted May 31, 2013 Author Report Share Posted May 31, 2013 it has NO spark at all. so i decided to take the coil to a motorcycle mechanic and he told that a coil doesn't damaged so easy . he told me more likely the stator or a black ishh thing battery under the flywheel or the switch are use to damaged faster. he didn't mentioned how to look for problems. so if the stator is damaged ? could you see it by a burn color on the stator? how to look /check/test for the electral problems?

andres1 Posted June 1, 2013 Report Share Posted June 1, 2013 Check ur ground, pick up coil gap, make sure that u didn't unplugged anything when u were installing the pipes. Sent from my SAMSUNG-SGH-I717 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted June 1, 2013 Report Share Posted June 1, 2013 You can check the ohm resistance on every component except for the CDI, and I find checking the stator to be sketchy. What all EXACTLY did you do from the time it ran until it didn't? We will try to help you get this running again. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted June 1, 2013 Report Share Posted June 1, 2013 Just curious, what is your compression? Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted June 1, 2013 Report Share Posted June 1, 2013 Checking a stator prior to a trip has proven to be a hit or miss. The spare stator I had tested good but was the biggest pile of shit I could of had my hands on. It was dead on arrival but tested good.

We will try to help you get this running again. i just woke up a day went riding it was on half tank ,then the gas obviously got lower and lower till the point it began to run like too lean so i open the reserve and then it still ran bad ,like a said in the reply before it stood a while outside in the sun (dirt ,rain all that shit!) so i taught maybe due that the gas went so low ,it could be that it suck some dirt in the jets, so i made the carb parts apart and clean them and it had no sign of starting. i went checking for spark (coil)and had no spark. i also changed the stock filter to duo race filters.

lugene Posted June 4, 2013 Author Report Share Posted June 4, 2013 Just curious, what is your compression? i didn't test it by a tester. i "think" the compression are ok cause it ran great and with POWER, it started in 3 to 4 crank ,like they say when your compression are low you can literallly crank it with your hands and i can't i can bench 180 kg chest press so i don't think it is the compression and another fact is that my friends have new banshees and i compare my compression to there shees Quote Link to comment Share on other sites More sharing options...

Sent from my SAMSUNG-SGH-I717 using Tapatalk 2 i just changed the stock filters to duo race filters ,but it started after. i didn't touch with any wires just changed the pipes .another thing where to start looking for ground wires (stator ,pickup coil,switch etc )blue right ?
