Oddly enough, I can get it to start first kick five or six times by rolling the tps counterclockwise. I say oddly enough because I believe counter clockwise raises the tps voltage (more rich) and I was assuming it was too rich since I'm having to pull and drain the fuel line to start it. But then after five or...

Lots of moving parts in a four stroke engine...if you listen close enough you're bound to hear something 😉. But to me this engine sounds healthy at least over the video and I've built well over 100 4 stroke engines over the past 10 years.

I pulled the injector and I kicked it until line was fully pressurized and it squirts a good mist...never leaks, works as it should. This is killing me. This is the second night I'll probably be up until 4am working on this thing I'm starting to think it's just somehow running too rich. And pulling the line allows it to...

I'm starting to think the same. I am going to check for a leaky fuel injector like paw paw suggested, but if that doesn't work I may just have to make the trip out and swap tanks. This fuel pump is brand new, however what is not new Is the pressure regulator on the pump housing. Maybe that's at fault...

Paw Paw, When I unplug the fuel line, there IS fuel coming out, (from the line, not the tank, as it shouldn't when not running) and as a matter of fact I have to dump the fuel out of the line before plugging it back in before it will start. I have tried with gas cap off and no difference...

Also, I not only have to unplug and replug, I have to dump the fuel from the line out and then replug. What on Earth. But yes when it's running it stays running as long as you want flawlessly.

Yessir, that is what is so strange. I don't believe it's a vaccum building in the tank, because pulling the line from the bottom of the tank won't let air in, the same way it won't let fuel out if the bike is not running. Has an electronic check valve on the pump. Once I get it started, you can...

Now... Bike will start after 5 kicks...

GingerVision87 Started a new thread Crf450r Head Gasket Nightmare

9/15/2019 3:32pm
Bought an 06 Crf450r that had the typical blown head gasket symptoms, white smoke, coolant filling crankcase, pressuring cooling system with exhuast, etc. Pull head and replace headgasket, runs great, no more smoke, no more coolant in oil, but then i notice from the back left portion of the cylinder it is leaking oil out of the headgasket, not coolant...

Pics coming later tonight, Rekluse Z start pro clutch and Scotts Steering Damper from a 2009 Crf250x, Both perform perfectly. Steering damper includes mount specific to the crfx model, if you want me to seperate and just buy the damper (that will fit any mount) I am willing to seperate. Both the clutch and the damper should fit 2004-2017 250x...

Yep Im pretty dumbfounded. Trans breather was clear, cavities were clear, reed oriented correctly and passageway into the pickup/stator area was open, reed functioned properly....I dunno. Maybe just some weird fluke. Im cutting a new gasket now on the cricut and will post an update. Everything else in the motor was mint.
