HI i just got a 92 rxl 650 last weekend. it starts up easy and runs but it was really boggie and wouldent hardly move. it has spark 2 all 3 cilinders and has new plygs. but i pulled top of air box off and the cilinder the farthest from the clutch side is throwin fuel mix into air box. ANY IDEAS WHAT MIGHT B WRONG? THANKS

Is that plug cold compared to the others?

what do u mean by cold? i dont wana runn it long if theirs somting wrong but i have switched plugs around among cilinders and still nothing. i can hold throttle and it just boggs down most of time i went a lap round our trees and it wouldent go more than probly 5 mph

Is it an EFI?

My RXL will not run with a weak battery. The EFI needs a good battery to operate properly.

brand new charged up battery the other night. and yes its efi

Is it flashing any error codes? After the motor has run do any of the plugs feel cold to the touch?

 

[92higgyrxl]

idk about the cold plugs but ill check it out tomarow and how will i b able 2 tell if it has any codes flashing?.............and thanks to everyone tryin 2 help

The black module on top, there is a light that will flash on the side. I dont have my manual with me but you can search for flash codes.

If after running a while, is one of the plugs cold or barely warm when the others are too hot to touch?

Could the reeds be bad?

 

[jamesu9165]

don't believe that motor has reeds

 

[92higgyrxl]

no reeds. all plugs feal the same dident see anyt codes on the efi box

Have you done a compression test?

 

[92higgyrxl]

Well problem solved. it ran then just quit compleatly lastnight. so i started testin everything and the new battery was low even tho it was charged and put in friday. so i charged it did a load test and had a bad cell. it runs like a dream now. id like 2 thank every one for helpin out and givin me ideas of what coulda been wrong. Thanks Again it was greatly apprechated

Good to hear, these efi's need full charge to run.

Did you check to see how much the charging voltage is? When I test mine I only get about 12.90 volts, which should be enough to keep the battery charged, hopefully.
