I got my leo vince exhaust yesterday. When i reseved it i was pretty happy to see its a great product. Well after putting it on I look a few runs up and down the street with and with out the silencer in the muffler. I didnt really notice a diffrence in power between it being in or out. Just without it, it sounded deeper, and in more high pitch.
What do you peoples think in your situation? Did you notice any diffrence with or without it in? just curious to see what people say

i didnt..but i had to jet high..with the filter w/stock intake tube and the leo w/o the silencer im running a 95mj and shes pretty nice..but i love the way it sounds..it sounds just like the bbr exaust they make for the xr50..its baddass i love it

95 main?! Holy shit that is alot of fuel!!!!



how's your plug look? I'd think you'dbe running really rich!

naw it looks ok..and its the best it ever ran..i had the 85..n it wuz ehh..the 90 helped but she still had a sputter..and the 95 is the king i guess..shes very responsive with no sputter anywhere along the line. it doesnt bog out at all she just keeps going..but the plug looked fine when i check after a run down the road

and btw tuesday i got my cdi so let me know when u wanna go ride..did u mean this coming up monday or next monday..let me know im readi

Tomorrow afternoon...


My girl and I are available after 2:30pm!

95mj huh. wow i was just gonna go with like an 85 running the leo exhaust and stock intake with k/n filter. do ya think the 95mj will be needed.

stock intake? u mean the big restrictive black box with a k&n? imo thats pointless and dumb..ur just making something SUPER RESTRICTIVE less..u know..i would just got with a filter on the stock intake tube outta the box..thats wut im running..and also i took out the baffle,spark arrester wutever u wanna call it outta the leo too...i thought it sounded like a stock xr250.. pretty gay..i seen the screw..took it out and now i sound like my pit bike..a klx110 with a bbr d-sector on it..sounds just alike BADASS but with the filter tube and leo im runnin the 95..if u got the leo with the baffle in it and u got that stock shit.. then yeah a 85 MAYBE a 90 should work just fine..

oh ya thats what i ment the intake tube not the box. and i am running it without the silencer,baffel, whatever you wanna call it.

oo ic if u have the pod filter with the tube and the baffle out then im runnin the 95..thats exactly wut i have..sounds a million times better with it out too

ya i cant wait to get everything. actually im only waiting on the jets. just out of curiousity with the intake/filter 95 mj, and exhaust is there a big change in horses. or is it just like "i can feel a little diffrence"

most likely little/no change or worse if tuned improperly

Ok well i don't want to change my stock airbox or intake system yet. I bought the bike with the leo exhaust and took it off and back on. I like it but my bike lags in the beginning and then picks up. I just changed my belt also and it help reach 45 on flat. Do i have to change the stock airbox for a new intake system? what jets to use with stocker?

i find that messing witht he idle mixture screw does wonderes for the low end!

get the tool, and start turning that screw untill you find a good spot!!!

you may have to re-jet, but that doing the above would be a step in the right direction

is the idle mixture the screw on the left side of the carb? Thats thing is hard to screw.
