Jetting!!! Again and again and again!
stujordan:
Stock pwk 39 carb and 7 slide
90 octane free of ethanol
32:1 supertech (cheap walmart brand)
Both air box vents open
Stock porting and squish....
I never hesitate WOT, but dont need it to smoke a 4-pump-chump (friends with 4-strokers) :evil:
Foxx4Beaver:
have ya done any plug chops with those settings...I would have to think the plug would look "brand new" white, from being so lean...but, I've never gone that lean before either, so I could be wrong.
no pinging with those settings?
stujordan:
If it pings its not noticeable...the plug is actually brownish black, but I dont hit WOT in every gear...
I see people reasoning going lean on the pilot and rich on the main is the ticket...think they should talk to desert racers for the best advice....bought mine from such a person. It has over 20 hours since I bought it from the dude...
stujordan:
Just read a post on another site that runs a 148 and a 48....might need to try that with a N82T needle...as is im a little rich....
Thoughts?
Foxx4Beaver:
I wouldn't, but I ride in the upper revs for the most part...
when was the last time you did a compression check...or rebuilt the top-end?
