ok sorry about the quickness of the post

the bike is new to me but i have been through the carbs?  the bike has been ported the original owner told me so.  also from looking through my    
manual i see that when it cam to me it did not have the stock jets in.  This is probably good for when he wsa racing it brand new 20 some years ago but now i cant imagine that it is helping it any.  i ordered the stock jets from bing and installed them and cant even start it now.  so i was thinking of going back to a bigger idle jet to see if it will get running.  as for the high end bogging then crazy acceleration problem do you think i could jsut throw a smaller jet in im in the process of trying these things as i have been for quite some time

thanks in advance!

Hey don!
Where are you in NH i am from Lee, NH, just bought a penton myself!

thanks for the info! now also if i am doing these test and such with the air filter off or with a modified one would that cause it to run differently?

hey i got it running and its sounds good there is lots of engine noise do those ktm 400cc motors make a lot of knocking?

ok so i just found out my 77 gs6 400cc has had a little motor work like some porting.  So the motor had been rejetted but when i ride it it bogs in the mid to high end and then will take off screaming all of a sudden.
What might this be? I have many jets for the bike do you think i could just put a different main jet in it?

thanks in adavnce!

ok first is a fuel question what is the deal with leaded gas should i be running that i just got a manual and it says to use leaded? second, i am running the original bing 45 or 54 i cant remember the number but its on the 400cc. Anyways, i was wondering if anyone else running this carb new how there carb is set up.  I mean how many turns out from closed is the air screw and idle speed screw also the same with the jet.  The bike is running really rich so rich it sputters oil out the exhaust and will run for just a little bit.  could this have to do with running unleaded opposed to leaded gas?

thanks in advance!

well ok thanks for the help with the fuels questions. now heres the next one: so this bike hasnt run in a long time but it is in great condition so i have no reason for it to have any problems but i was pretty sure i wasn't going to be able to kick it over first time probably gonnna have to role start is since it seems to be a high compression 400cc.  But when i do kick it something strange seems to be happening.  instead of the classic thump thump thump thump and the kick starter goes down there will be nothing except smooth, hard, even pressure for a couple pumps.  Then it will finally give a couple thumps and go back to the hard even pressure.  I took the exhaust off to feel the cylinder as i was pushing down the starter and it was not moving at all while the strange smooth hard even pressure was occuring.  Then when the normally thumping would occur it would move a bit. And no the kick starter isnt stripped and not catching.  Also i pulled the motor out when i painted the frame so i took the head off.  when it was off i pushed the cylinder up and down a little just to inspect the walls could i have gotten something out of alignment? thanks in advance! i hope this makes sense!

hey folks just bought a 77 gs6 400 just got a few questions concerning work and maintnenance it needs first: what is the fuel mix it takes? also how much gear oil does it hold and how do i know what full is? and finaly is there anyplace i can buy generic orange plastic front and rear fenders for it with out spending too much money? any insight would be great thanks!!
