Bansheeman1121 Posted April 25, 2005 Report Share Posted April 25, 2005 (edited) Ok i will start off comly and give everyone everylast peice of info i have on this fucking thing sitting in my driveway, 1st off mods noss head 20cc domes, vforce reeds/ reeds spacers 30mm mikuni carbs fmf fatty pipes with toomey t-3 silencers weisco .80 over pistons wiesco hot rods crank noss airbox adapter plate with k&n air filter Ok just got finished buying tons of new shit for this thing having it all profesoinally installed, got it home a few days ago and it runs like shit, on idle it seems to "load up" after about 10 seconds then when you hit the gas its not that quick to stroke rev its just a long kinda bog but it revving not dying. just not that clear two stroke rev kindasounds like its choking from the cylinders, dont make much of a sound from the pipes. OK Then if you can manage to clear it all out it it revs decent wide open in 4th 5th and 6th, I have tried everything from 290 to 220 mains(currently running the 220s) running 25 pilots and not sure where the needles at. Basicly 1st 2nd 3rd 4th suck there not like they used to be there just a long bog no powerband, plugs are black somewhat tan. My ratoi is 3 1/2 ounces of amsoil to 1 gallon of 93 octane im at about 1400' ft.Today my problem got worse, 1 cylinder runs perfect the other runs like shit the pipe barly gets hot while the other pipe is very hot, barly any exuaghst, and just started making a wierd popping noise not really like a backfire just pops,also theres alot of opil which pours out of it but the oil seems to be really thin and watery and smell alot like fresh gas that hasnt even been burned up , and this thing is definatly not lean- this is all with fresh plugs. I spent over 2300 doallars int he 1 year ive owned it and its ran about 5 months and blew up 2 times since ive bought it 1 year ago, im out of ideas guys have had it in and out of shops, any any idea at all i would really aprecate it i almost get sick when i think of all i put into it and what i get out of it plz guys help me out....

NugShee Posted April 25, 2005 Report Share Posted April 25, 2005 First of all dont give up, your just about there. Your jetting is just off is all (way off). pilot jet should be good. Needle should be in the middle notch to start with but Id say the main is way off. I would start at 300 and go up. but before you go switching jets make sure the carbs are in synce. Take the air filter off and look into the carbs from the back. while slowly twisting the throttle make sure the carb slide go up at the same time. If this is off then you will have problems like you are describing. Sync your carbs, go up in Jet size, take a plug chop and then we'll go from there. once you get it all dialed in youll be glad you didnt get rid of it.

boonman Posted April 26, 2005 Report Share Posted April 26, 2005 With 30 MM carbs, I would not start at a 300 main. If you had stock carbs, I would start there. I would get rid of the reed spacers, unless you need them for spacing the carbs out to clear the clutch lever. WHat kind of Amsoil are you using? Hopefully not the 50 or 100:1 stuff. Re the reeds in tact, and functioning properly? I know you stated they were brand new, but I have had a bad set of reeds right off the shelf. Have you tested the engine for an air leak? (a leakdown test) If you haven't, I would definitely do this. That may be the problem. It will make jetting impossible. Quote Link to comment Share on other sites More sharing options...

Bansheeman1121 Posted April 26, 2005 Author Report Share Posted April 26, 2005 Thanx for the replies so far im really considering a 250x or a mojave at this point, whats the best way to check for an air leak, the reeds are fine, and why would one side barly run Quote Link to comment Share on other sites More sharing options...
dlnoss Posted April 26, 2005 Report Share Posted April 26, 2005 Check some of the simple things first. Carb slides synced, slides in correctly and not sticking, cross tube connected. Good compression on both sides to make sure the domes orings sealed properly. It could be a leak around the reeds or reed spacers. If you made all the changes at once, you might back up like remove the reed spacers and/or reeds and see if the problem goes away. Quote Link to comment Share on other sites More sharing options...
FadedDreams Posted April 26, 2005 Report Share Posted April 26, 2005 I would agree to that you are really rich.I have 28pwks bored to 30 and i'm at a 135 main i think,might be a tad bigger.Least that might be a place to start on jetting.

wayfst Posted April 26, 2005 Report Share Posted April 26, 2005 make sure that there is nothing in the pipes, like packing peanuts, makes for a bad experience. other wise jet,jet, jet and then jet. Quote Link to comment Share on other sites More sharing options...
rider22 Posted April 26, 2005 Report Share Posted April 26, 2005 There should be a rubber line, not the balancing tube, that connects the two carbs which is located on the inner sides of the carbs. If it is not connected it will cause an air leak which creates symptoms similar to those you describe. Quote Link to comment Share on other sites More sharing options...
duner Posted April 26, 2005 Report Share Posted April 26, 2005 Too much oil on a K&N will choke the air down also,making it run rich. Quote Link to comment Share on other sites More sharing options...

Bansheeman1121 Posted April 27, 2005 Author Report Share Posted April 27, 2005 Thanx for all the replies, alot of people are suggesting a bad crank seal?? since its the right side that run shitty. I find that unlikly becuase the crank was just installed by a pofesonal. Also would way overfilled gear case oil cause some to get sucked up to the top end?? Its a reall thick white smoke comin from the right side with a really watery gas oil mix coming from the right side, but like i said it smells like fresh gas that never went through the motor spark seems good switched up the wires and its same. Switched carbs and ran the same, also theres no choke tube on my aftermarket carbs, im gonna have someone who owns a see take a look at her tomarow but what are the symtoms of a blown seal on the right side, thanx again,, one more thing what is symtoms of "pre detinatoin" im running 93 octane with 20cc domes at 1400 feet elevatoin Quote Link to comment Share on other sites More sharing options...
