looking for a carb

[allsmilez620]

Hi iam new I have been reading alot of stuff about my lt80. An I have done alot of stuff to it from reading the threads this is great . Well heres the list I have a Shaved head runing 148.psi cold,new boyesen reeds ,13 tooth front sprocket,did the clutch mods,an took out roller weights and took out the oil injuction and gear . and dg pipe and no air box. I think I need more cfm to the motor dose not sound right takes to long to get to top gear tell me what you think thanks

[LT80]

Put the rollers back in. :)
I don't know why removing 2 rollers works for some and not others. You can try 5 rollers.

My motors can rev to 12k+ with the stock carb. I don't think it's the carb. :D

So tell me about this "no airbox" thing.

[allsmilez620]

well it had no air box on it when i got it just an after market fliter . What size jet should i run then ill put one roller in and let you know .And is there any other stuff i can do thanks for the help lt80

[LT80]

Stock main jet is a 92.5
You can safely go down to a 90.

ok what you think that when i try to take off it feels like it takes a sceond for the power to kick in like going up a hill but when it goes it goes i put the 90 jet in you still think i need to put the roller back in the top end feels good now its now the bottom end thanks

[LT80]

Ahhhh...the famous LT80 bog. LOL
To help that you must cut the rear clutch shoes down to 180 grams each.
Ask etondaddy for the pics. :)

Thanks lt80 for all the help so far. One more thing did the clutch mod ok i have the 90 jet in and i have c clip on the niddle at the verry bottom setting.Where do you think I should have it. Ok now when i take off it breaks up a bit before it launches ,and what oil ratio should i run with the shaved head thanks so much

[LT80]

Breaking up eh...Maybe the 92.5 main jet needs to go back in. The lack of air box may make it that way.
Put the clip where it runs best. :)
I use 32:1 with a good synthetic oil.

thanks runs great now just got back from the trails where can i find a big bore kit and a biger rear sprocket thanks for all the help lt80 just wondering how fast have you got an lt80 up to

[LT80]

flat track racing...60 mph. Stock bore and carb.
53 on a TT track. usually around 45 for MX.

Ok, a cpl things to know..
1) A bigger rear sprocket slows you down/gives more low end grunt.
2) A 105 kit is actually 96cc's (with stock stroke) and one of the biggest wastes of money out there.

If performance is what you want I can help.

[allsmilez620]
