First race ever!!!

i can't beleive i read all of this... well... 10 pages at least...
Well, probably going to say something thats pretty obvious... racing is hard on your bike. Down here theres a lot of crazy racing... We have an atv salvage yard.... hudge... Its amazing some of the stuff you see there. I'd say you may need to reinforce your frame. If your running amuminum wheels, there is not much give as carbon fiber might have, so all that force is going to go on your bike. I'd also recommend getting some beadlocks, hate to have a tire come off the bead in some rutted berm. Theres a lot of things that i would need to race a blaster lol. To me, the blaster is a pain to keep up with the 4-strokes. It really.. wears me out. And if you dont hit the powerband and keep high rpms right before a jump or a donut, your going to look ridiculous. (trust me.. i know) And the stock suspension on the blaster is pretty rough to. Versus my old 300ex, the blaster would be a pinto, and the 300 would be a caddy. I don't know what all mods are done to your blaster, so, just throwing out my 2 cents. There are also all kinds of steering stabilizers, holeshot lowering devices, little nifty things like that you might could look in to... so.. yeah, good luck with that.
 
Too lean on the needle, I have found that low/mid pipes like it slightly rich on the needle.

Stock is middle clip, try moving it down to the 2nd from bottom.


i tried the 3rd clip, and it was too rich. it would gurgle in the mid range, than clear up top end.

ima not be racing that hard. i wanna win, but im not willling to spend thousands of dollars on repairs and be pushing me and my bike to where it breaks every race. and my class is gonna be 200cc 2str and 400cc 4str class, and maybe quad c when i get better, thanks fopr the info tho!
 
Maybe the Gnarly likes it leaner in the middle, the plug chop in the other thread would suit my expectations, I prefer to be on the rich (safe) ide.
 
I run a similar set up to yours, other than my air filter is directly on the carb throat, and 25:1 premix.

A #340 main is what I use, even with temps in the high 90s.

You must warm up to operating temp before you give it any big throttle, and must clean out the motor at the start grid or you will babble all the way to the first bend.

If you warm up and clean out it will go like a shower of s**t.

As the air temp goes up, the mix will only go richer, if it babbles swap back to the #310. If the babble goes away after warm up, leave well enough alone.
