Well, i got it home, it started right up. Let it warm up and i decided to go for a ride, Well, it runs great 1/4 1/2 but as soon as i hit the 3/4 full mark it starts cutting out, like it's drowning on gas.

I had to adjust the low idle, is there another screw to adjust the higher RPM level? Or do i need a smaller main jet?

I'm not very good with carbs...it's not my thing. Or could my plug just need replaced?

Any help will be greatly apperciated

 

check your airfilter... it could be because of restricted airflow...


Oh ya is this a new 300 or a mod'ed one. if it is it could be you need to take your airbox lid off and get a better filter

 

It just has a curtis sparks racing pipe.It has a K&N filter...well i think it's a K&N.

I took off the air box lid, it did the same thing. I'm thinking i'm running rich. I'm going to pick up a new plug tonight, or tomorrow, and try that out.

Maybe i should just call LRD and order a whole jet kit for it..

Any other thoughts?

Also where can i get good aftermarket tie rod ends. I would like a webpage.

Thanks

 

mine was done that ans it was cuz that little line that comes from the gas tank to let it breath was kinked. Or i could also be your fuel peacock

 

I think i am hitting the rev limit..But then what is it set at?

Because i'm used to reving my blaster up.

I just got in from trying it again, if you rev it up in 4th and 5th it doesn't do it. Just in 1st 2nd and 3rd. Maybe it's just geared a lot lower than i am used to. I can take off in 3rd just fine!

 

There is really nothing wrong my 300ex dies that to.It really isn't doing nothing unnormal it is just I am used to rding my 250r.I hope U like your new ex.I certainly love mine!!!

 

that makes me feel a lot better knowing yours does it too!

I'm used to reving the heck out of my blaster to get it going.

I miss the 2-stroke. I love the thump and torque of the 4..but the hit of the powerband, the smell of the 2 stroke oil.....ah....fond memories....

Sorry, i'm back now....Maybe when i get more time on the 300 it will feel better, i got about 30 minutes on it today, it's raining so hard, I tried riding in it but only managed to get drenched! From helment to shoes!

 

Just got my 300EX this past Friday and I had a similar problem. Got home from the dealer and backed it off the truck and went around the yard a few times. 1/4 to 1/2 throttle was fine but if I really got on it, it would bog down. Finally I realize the dealer had left the choke in the middle position. After correcting this it has run great!

 

mine DID that when i first got it. make sure youve broken the quad in. after i modded it, it started doing it again so you have to like break it in again i guess.

 

It's not doing it at all now, i think i was just reving it high, It just seems that it's geared low, In first you can hold it down for only a second before it starts to rev up, then 2nd is the same way.

I have 20" tires now
