how is the burn on the plug?

155 and under pump anything over i run race fuel its not worth pre igniting your motor,stay with the 21s on that motor its safe and power increase from 21s to 20s will be very hard to feel,static comp is only 1/2 the equation

hes talking dirt your talking asphault for asphault american racers sd-23 compuond

Either you filled it up too much or it blew a head gasket thats why its running hot,whats your mods and jetting at now we need a baseline to help you properly

IO would do a pressure test and a compression test to make sure the motor is tight and the rings arnt frozen,seals go bad if something sits 4 long periods and rings can get stuck in the lands

yup get a 22 inch cheng sheng or turf tamer and screw the shit outta them with ice screws,I have a couple diffrent set ups running theses tires and im on the bar half way down the track

cheng shengs with screws

48 pilot 160-165 main,cel needle 4th clip

leave the 290s richen the needle up all the way and close the air screw see if it helps

Dude stop putting cranks it it.Get all your shit checked out,cases, cylinders,possible shits just wrped but looks like you cooked it from lean condition

how much could they be,im sure someone on here has one sitting in a junk pile for years i know i do somewhere you can spend time tasking it apart to break it then do it again,you can go broke saving money,ill take a look if i have on layin around and it check good on the true stand ill send it for shipping ,or if you need it assembled send it to me ill assemble it n ship it back,or you can keep it gangsta n tack weld it on ,its only a problem if you change sprockets like underwear

I think 850 is hella cheap top n bottom,if u had a hairline crack in crank new one is 350,50 for seals,300 for bore n pistons,50 in misc gaskets how does that guy make money just hope he inspects eeverything else that goes along with it,basket,hubs,forks ,studs i can go on forever but im anal

twin 39mm pwks or nothing,you need to feed that beast

look on clutch side primary drive gear,the little keyway will leak or bad crank seal,I dont let a motor leave till its tight (no loss)

The ones i seen come apart should have never went in IMO,people dont like to listen tho,they think your allways trying to sell something,im just a big 3 fan i guess.EVery bike i see puttin power to the track is runnin 3s

by a sync tool and replace exhaust packing,FAST racing carries them,785-364-5325

16mm is the float height with carb tilted on the side so the float just touched needle and barely pushes on the center spring,check the float b4 you burn it up.You should also be in the area of a 195-200 main

One of my close friends didnt have enouph money for pipes after i did his motor,4mill long rod drag ported,stock carbs and sst .It works fine i would try it,he says bottom is great

I also drill the caps out on ported bikes

I feel the opposite i feel 3s make more top end power and are snap together nice units,i have them in 6 diffrent drag bike plus about 30 trail bike with no issue,and i have seen 2s come apart

read on the forum how to do a good plug chop , 5th gear is better,the whole idea is having enouph fuel at full load in 6th topped out,for quick adjustments i will do a 4th gear cut and look at the base of the threads on a used plug after bike has been dialed in for a certain track,155s are safe see how she feels 6th gear

I have a set of cpis on a ported cub and a set of shearers on an unported cub,the shearers def feel better up top but from a dig the cpis short distance i cant tell the diffrence

Thats what i said! im used to runnin the 1/4 and since im only getting a couple of runs at other tracks and not able to tune much im gonna give it hell for the 1st 100ft.I went down on sunday and there was a big turnout only one quad tho,fuck it im doing nothing imprtant and its a half hr from me.I figured ill practice my launches

On june 26th in riverhead long island there will be 100ft asphault drags,a holeshot event.Its not a long run but it should be a blast considering they closed every other track around here.The track guys said bring whatever you want you can run a moped if you want.Anyone around here interested hit me up ill let you know where ill be set up

wrong.chop the mains first,then worry about the rest,I went as low as 138 mains in those carbs on wacko 2000s bike an 42 pilots,his bike is heavily ported
