Hey houston, my Toro Nero came with two aluminum, and two copper shims. This is the non turbo vrs. So my question is there .10 copper shims?
I dont have any calipers, and you mentioned the aluminum would be .30

Oh yeah both copper look to be the same size, and the same with the aluminum..

Im running byrons 30/11

Thanks for any help...

Hey Monty
I hear you're coming down for nitrocross. Awesome. I got a tuning question for ya...

I got this GRP from a buddy of mine, sans carb... so I put a carb off my werks 7port on it. High end is awesome, ran last night at srs, 2 quals, main, practice... 220 degrees each time. My issue is this: low needle and the balance between the two. It runs great, but for some reason after refueling, if I don't pin it for a second, they'll throw it back down, it goes like 10 feet and stalls. Go to restart, and it's flooded. I leaned the bottom out, and it's 80% better. It's perfect all over the track, but at the end of the straight, i take a right hander and it's surging. real high idle speed for a min. Sofar, I've been going in the right direction, i think. Originally it had a rough idle, and we raised the idle stop to keep her going. I think it needs a little leaner low end yet. I leaned it out last night between heat 1 and 2 and it was much better, and dropped the idle stop a little. As I understand it, I keep leaning it out on the bottom a bit more and when it picks up again, drop the idle speed again? Really, it's running great, great power, and PRETTY MUCH reliable LOL... but i don't want it to die after I get pitted, especially if it's gonna be flooded. Last week it took 5 min to get it fired again. This week, it did it only once, and it fired in about 30 sec, so I think i'm headed in the right direction. sound right?

ps: I KNOW, JUST BUY A NOVAROSSI. I will be soon

it a grp man here a rule for that motor fat top lean bottom. is the way that motor likes to run and 220 a lil hot for a grp it like to run 200 210 at the most
also whats wrong with the stock carb?

two .30 and two .10 = .80mm

i am pretty sure the os carbs work excellent on the grp engines . the grp engines tune like a vspec low end a little richer and hsn leaned out until it rips .



p.s. yes

.

i dont use them personally for the simple fact that it is another place to form an airleak and another item to find a place to mount it . i have seen them in use and noticed a definite increase in power and runtime . cooler fuel definitely makes more power cooler fuel definitely burns more efficient

combine these two things and there has to be an improvement

just keep the fuel in a cooler

hey monty figured i would give u an update. i had a pm from casey peck tellin me my dad ran it to rich and idled to long and it hydro locked then he kept the fuel in there which caused it to be sticky.

he cleaned it all out and it started right up now. but he couldnt get it to stay runnin, i think its to rich so im going to look at it tommrow since im off. he blew our starter box motors due to tryin to start the motor for 30 sec he said. kinda makes me think what the motors in for LoL...

thanks for the help

um ya

i thought i said something like the cylinder walls were gummed up with the fuel . use heat gun! keep temps up to at least 200* !! very key run in instructions

you did. and i was going to do that. he just provided an explanation lol. like i said thanks ill reintroduce my self when u come for nitrocross

Thanks. GRP carb is missing... out of all the carbs i got, the werks is probably the best shape. i'm using a red insert (not sure what size). like i said, it's all bottom end where my issues are. thought that was a lil warm for GRP. I'll give it a whirl. if not, i'm sure i can find an os carb (thanks Monty!) and maybe play with some pipes....

Still gonna buy a novarossi in a bit!

chris, i have a grp carb a i can sell u. 30? pm me if u want it. or i have the grp with pipe needs new p/s for 100 lmk

Thanks...
