question about a vspec engine - MX_KEVIN - 01-30-2008
V spek like to run fat on the bottem. High speed and the midrange @ 2 oclock / is all ive ever changed. I have 2 and not much diffrence between them.

Thanks guys, ill try that stuff, but first i gotta get a new one of those plastic pieces that goes around the carb neck where it goes into the engine case at. I tried to get the carb off yesterday and that took forever, plus the little plastic thing was melted onto the case b/c we had to heat it up to get it out.
question about a vspec engine - motoxer4life - 02-01-2008
When i took apart the engine the other day i noticed that the top of the piston was a little burnt and black, does this mean i was running it too lean or is that normal?
question about a vspec engine - J-Dub - 02-02-2008
A brown color to carbon color is normal. thats some deposits from the engine burning oil.
question about a vspec engine - rocco79 - 02-03-2008
how many gallons are on this mill?~
question about a vspec engine - motoxer4life - 02-03-2008
about 4-5 maybe
question about a vspec engine - rocco79 - 02-03-2008
how does it run now? still blowing plugs?
question about a vspec engine - motoxer4life - 02-04-2008
ya, havent ran it since i asked that question, but ill try it out soon.
question about a vspec engine - rocco79 - 02-04-2008
If it still blows plugs id still say replace the rod
question about a vspec engine - motoxer4life - 02-04-2008
The rod was fine, i checked it. I think it was running a little to lean
question about a vspec engine - rocco79 - 02-04-2008
did you measure it or just eyeball it?
question about a vspec engine - motoxer4life - 02-04-2008
Eyeballed
question about a vspec engine - J-Dub - 02-04-2008
trust me your eyes are not a micrometer. even a few .001's of an inch is out of spec, throws off your compression ratio etc...

" I eyeballed it" Wow.... yeah that should be accurate. (Christ)
question about a vspec engine - J-Dub - 02-04-2008
yeah...Hahaha.
If you've got micrometer eyes and a digital readout, go be an engineer.
question about a vspec engine - motoxer4life - 02-04-2008
I am going to be an engineer,and i know its my tuning because my bros engine, which i also tune, has been doing the same thing. Theyre running at like 250, you think i should richen them up a bit? Im resetting the needles so i can start over.
question about a vspec engine - rocco79 - 02-05-2008
Nahhh.... Just keep putting plugs in them.
question about a vspec engine - DAVEC-NITRO-RS4 - 02-05-2008
how many plugs = one rod?
question about a vspec engine - J-Dub - 02-05-2008
like 4-6
rod is prolly like ~50 bucks
question about a vspec engine - motoxer4life - 02-05-2008
its $39.99. so your saying both rods in both of our engines are messed up?
question about a vspec engine - rocco79 - 02-05-2008
Im not saying they are messed up im just saying there isnt much else to explain the popped plugs.... At the begining of all this you said it WASNT the tune so we all have thrown our .02 in the ring to help you.
question about a vspec engine - J-Dub - 02-05-2008
its worth a try...replacing the rod in your 5 gallon mill might be a good idea. breakin stress, and 4.5-gallons of abuse.
question about a vspec engine - motoxer4life - 02-05-2008
I said it feels fine, not that it was fine, i still got alot to learn when it comes to tuning. Idk, i reset the tune, ill test it, and if get it all retuned. If thats not the problem, ill get the rod. Thanks guys.
question about a vspec engine - cheesecake - 02-05-2008
you might as well do the bearings if your going to do the rod thats my plan with the p5
question about a vspec engine - motoxer4life - 02-05-2008
I just changed the front bearing when i had it apart
