can anyone give me a idea of what size the main jet needs to be with a dg pipe and stock filter around 1000 ft above sea level.thanks

 

PM LT80 and he will probably be able to tell you!

 

It's hard to say.I dont see whay a DG pipe would require much of a change.It'd help if we knew how it was running.Is it blowing smoke bad?Sputtering from too lean?
If your just afraid to do damage,don't be. Install the pipe and run it. [img]i/expressions/face-icon-small-smile.gif[/img]

 

well the bike belongs to a friend of mine.he put the pipe on and said it would not run without the choke on he was right .so i took carb off raised needle up all way still i could not tell a diff.then i took main jet out an got drill bit just alittle bigger than hole drilled the slapped it back together runs perfect now except at wide open where it blubbers out bad.

 

Well I guess you need a bigger jet/drill then. [img]i/expressions/face-icon-small-happy.gif[/img]
I will offer to send you some jets. I have up to 110 or 115..That way you could have a few to try w/o having to buy them all to try.
If interested,let me know. [img]i/expressions/face-icon-small-smile.gif[/img]
