blaster oil injection question

[ctclemes]

i have a blaster with fmf fatty with power core ii pipe, k&n air filter and a 250 jet. im also using the stock oil injection ( i like the convince ) but am wondering with my mods is it giving the motor enough oil? sometimes when i go full throttle it will start to crap out and i have to back off. it doesnt do it right away but after riding for a short time it starts craping out at full throttle. any help?
thanks
clint

your problem sounds to be jettin, the oil mix isnt gunna change, have u rejetted after those mods?

 

[ctclemes]

ya it had a 230 main jet and i put a 250 in it.

270/290 main jet, 250 too lean

 

[ctclemes]

really? wow ok ill try going up in size. also what type of spark plug are you guys running with mods?

 

[Whitty21]

b8es or br8es are your plugs

I run a NGKR and it seems to make a difference over the regular NGK. I don't like to run the crap ones like "Autolite" or "Champion" but people have their own opinions. And as for the oil injection, I would take it off as fast as possible. They are turds and as someone on a different thread said about the TORS, "I believe Yamaha added it because they were mad about Pearl Harbor." Lol. I believe it may have been awk or noober. But anyway, its costs less to buy the eliminator kit for the injector that to get a new piston, rings, and get the cylinder honed after your motor goes pow.

do the oil injectors fail alot?

they are just really ez to airlock or forget about. premixing just takes away that variable

 

[acezeesawtooth]

yep its easier to premix and not worry about it... once you are used to mixing. its actually just as convenient as the injection except now you only have one tank to fill

 

[York Racing]

They can gum up, get dirty, you can forget about them, and when you premix you know its correct. And another benefit is that when removed, it reduces weight which is a good thing in general. The TORS also causes problems in the long run and is a good thing to take off.

 

[ctclemes]

ok. thanks for all the info guys. really appreciate it

 

[York Racing]

Sure. And for the elimination kits a good cheap place to get them is from Vito's Yamaha Performance. The number is 1-888-350-VITO. I'm sure some other places sell them but thats the cheapest I know. Hope the info helps. =]
