2000 400 SCRAMBLER LAST FALL (I LIVE IN OHIO)I TOOK IT FOR A RIDE (ABOUT 30 OUTSIDE). RODE IT FOR ABOUT A MILE AT PART THROTTLE. AND IT FRYED! I HAVE A HPD PIPE WHICH IT WAS FINE ALL SUMMER LONG AS FAR AS JETTING GOES. BUT NOT FOR THE TEMP. THAT NIGHT. STILL HAD WARRANTY LEFT OVER FROM 5 YEARS. TOOK IT IN, GOT BORED AND NEW PISTON. BROUGHT IT HOME AND IT STILL DOES THE SAME PART THROTTLE THING. TOOK IT BACK, THEY PUT ON A NEW RADIATOR CAP, BROUGHT IT HOME AND IT STILL DOES THE SAME THING. THEY DONT KNOW **** IT HAS TO BE THE JETTING????? HELP !!!!!!!!!!!




THANKS!!!!!

Sounds lean in the midrange,move the clip down a notch on the needle. Might need to go one size larger on the jetting as well.

 

Thanks whuggs, Thats what I think too! I just needed to hear it from someone else, I dont get to ride the bike that much, Bought a new house last year and havent had a chance to mess with it. Like I said before, I tried to talk to the dealer about it, they just dont get it! Thanks again!!!!! Mase[img]i/expressions/face-icon-small-wink.gif[/img]

 

No problem,I had the same problem with my 250 and melted a brand new wiseco[img]i/expressions/face-icon-small-sad.gif[/img] from what I hear temp has alot to do with jetting as well as altitude.

 

did after the rebuild did you re torque the head and base? my 2002 Scrambler fried because of a base gasket blew out....if you have any dampness around the base you might have a bad gasket I saw two of these do that one was a 2000 and was mine a 2002....just my .015 cents (after taxes)

 

I am going out to move clip on needle down a notch here in a bit !!! I will check that also! thanks hawleywood !!!! Mase

 

Keep an eye on your plug.
