tdod101 Posted March 26, 2013 Report Share Posted March 26, 2013 Mechanic tuned up the quad but apperently it gets warn and shuts down after high revving, he suspects it's sucking air from somewhere around the crank case area...thoughts ?

tdod101 Posted March 26, 2013 Author Report Share Posted March 26, 2013 do a leak down test. It's in his hands now, I'm just curios what it could be and why might need to be replaced and what it would cost. Does the engine need to be pulled and rebuilt ?

Does the engine need to be pulled and rebuilt ? Left side crank seal, base gasket, yes pull the engine and do it right. You gonna let a 10 dollar seal destroy a 1000 dollar motor? 1 Quote Link to comment Share on other sites More sharing options...

Starwriter Posted March 27, 2013 Report Share Posted March 27, 2013 That's like going to the doctor and telling him your stomach hurts and asking him what it costs to fix it. In your case, could be as simple as a reed block gasket or as involved as crank seals and a complete rebuild. Won't know till you do a leakdown test. If he has no idea about how to do a leakdown test, get your bike out of there. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted March 27, 2013 Report Share Posted March 27, 2013 Odds are if it's "shutting down by itself" you have engine damage. Quote Link to comment Share on other sites More sharing options...

hoppedupandcutdown Posted March 27, 2013 Report Share Posted March 27, 2013 it gets warn and shuts down after high revving Doesn't that mean that it is seizing up? Quote Link to comment Share on other sites More sharing options...
tdod101 Posted March 27, 2013 Author Report Share Posted March 27, 2013 Doesn't that mean that it is seizing up? Hmm, I hope not. I don't see why it would. It's getting enough oil and compression is good... Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted March 28, 2013 Report Share Posted March 28, 2013 Well if it sucking air then it's leaning out, lean mixtures run really hot. I've seen a runaway bike get extremely hot in about 5 seconds. The point to where I couldn't touch the pipe. Like stated, do a leak down.
