I clocked my 03 LE Raptor for the first time today. 65MPH. Thats slow as hell! MY warrior got clocked at 65, but it had +1 tooth in front. I checked my gearing, and it is 13/40 on my raptor. My buddys 02 Raptor (BONE stock) got clocked at 76MPH, against the SAME car as I clocked my Raptor against. Kinda weird....... Did my t-4 exhuast bring down my Top speed? Did I break in my Raptor wrong? Any ideas what the problem could be? Thanks

PS: If I buy a new front sprocket (+1), do I need to buy a new chain?

 

did u jet your raptor correcly ? if not theres your problem . other then that maybe clean your air filter .
just my 02.

 

The Raptor came with all of that on there, so I wouldnt know if they jetted it correctly. im sure they did becuase it doesnt bog at all....

 

i would check your plugs .. to see what color they are .. i think this is how it goes . if there black your too lean if there white to much air .. its one or the other either way u would know if it was jetted correctly if your plugs look normal no discoloring ..

just my 02.

 

when the raptor first came out Pro-circut made the claim that you did not have to re-jet with their complete exhaust, So this might be your problem, only way to find out is to check your jets, You'll need to learn to do this anyway....

 

I just checked the spark plug........black and chipped. Its not chipped at the top were the spark happends, its chipped where its black. Is this bad? Im gonna get a new air filter and new spark plug tommarow.

 

when u put the new plugs in run if for a few min then check the plugs if black or white go by a jey kit and follow the directions

 

ok thanks.

 

Black'n sooty means ur rich. Which would take away from top end. Open the carbs up and see what your mains are.

 

You have me lost. But I have a question, im revving out my RPM's, so how could I go any faster htan I am? It only revs out so far.... and it doesnt bog.
