this is build-up from two or three rides and no washing or wiping afterwards really, just getting the mud off the bike... its some grime and some dirt.... is this bad, should it not be this dirty? idk how it could be cleaner really.


.....when i have nothing to do i just sit there looking at the blasty thinking of things that may possibly be wrong or going bad. i just wanted to get some input on this.

might not be...nothing really stands out as being wrong. although i do run a 350 main in my bike which could be the reason. it has never been any worse than whats in the pics. i just want some opinions and suggestions really. i fear running lean and blowing up

HOLY sh*t are you running rich its no wonder why your shooting oil out the exhaust thats a really big jet even the most modded blaster in the world doesnt use a 350 main
 
well.... *INSERT WTF SMILEYFACE* HOLY sh*t......



how bout a suggestion then....but props to you for being the only guy trying to help tonight
 
a shop i do not attend anymore because i feel they are lacking in knowledge suggested this. never had a problem with it. i can get a new ..i mean, tomorrow. will i really notice a difference in lowering the jet?
 
i second that 290-310 is ur ballpark. ull notice a big change in performance and dont be scared to blow ur bike up. just run some extra oil in it. i ran 101 octane in mine once i felt i was running leaner so i dumped some extra oil in boy did she smoke and haul ass!
 
WOW! You are runing extremly rich.. I would try a #310 ... You will actually feel MORE power due to a more efficient combustion ! . . There is no way you will run lean with a 310...

I noticed you run with oil block off.. i dont know what you mix but go with 32:1 .. you be absolutly safe, thats also the pre-mix everybody else runs.. including me..
 
i run a 340 in mineI:II:II:I


i definitely dont have a toomey b1, and i myself, have never put aftermarket reeds. i want to though.
you think i should try a 310?

....and just for kicks. the shop i got the 350 from, doesnt stock anymore blaster specific parts except generic sh*t, block off plates and whatnot, and what they get from vitos...a vito's jet kit, and oil block off, which they are "out of" as well...the local yamaha factory dealer is closed mondays, and the only other shop is 30 minutes away. so maybe tomorrow

i do infact run 32:1 with ONLY belray H1R and belray, and gearsaver case oil on plus gas.
 
you could prolly get away with even a 280 or 290......idk what your pipe requires for a jet but from there go up 1 for the block off and maybe 1 or 2 for the air box off....so i would think a 290 would be about right....just get a few diff jets and a few plugs and do some plug chops...
