I have a quadzilla that has had port and polish job. From tudor performance with a 39pwk carb The bike has plenty of power if you got the revs up but at low idle if you hit the throttle it will bog out and quit if you rev it up pretty good its no problem i dont know if its the jetting or timing any help would be appreciated thanks. I just got the bike and have no history on it!!!

 

when it bog's down does it sound like,baaaaaahh waahhhh or does it just stall out?I mean does it bog out and then rev up?Sound's to me from my experience's through the year's that the low to mid range jetting is off,too lean.

 

If you stay in the gas she will bog and quit i have since found out the carb from tudors perf is a 39pwk with a power jet it says race only i am thinking this may be the problem my buddy just got the bike my zilla has a stock carb and i have no problems any insight would be appreciated...

 

Is the power jet adjustable?.If so shut it off and try it out.I have 2 on my Lectron carb,I had to lean the carb out some,and the adjustable power jet also,the other power jet is a fixed jet with Mikuni pilot jet's,I put a small one in and it work's good.Are you sure it's not a alky carb?

 

yeah it is adjustable and it is closed all the way down i will call tudors in the morning to see what they say

 

Sounds like jetting issues to me. Bog usually = Lean
