so started it up again just to make sure that I was not imaging things, so its smoking quite a bit.... but its white smoke. and The fuel that was dripping from the header now looks to be coolant. So I am assuming that I'm getting coolant in the cylinder. any way to be able to tell for sure before I pull the dome off? So time for a top end rebuild? Also the header seems to be loose on the exhaust flange any fixes?

Start it and pull the radiator cap off. Watch for bubbles. If it bubbles then your leaking

Dutch_Rutter · « **Reply #27 on:** November 27, 2013, 02:04:25 pm »

No bubbling.. So that makes me wonder why the smoke?

My guess, only a guess is that it's a two stroke?

clutch side crank seal? Is t trying to run away on you? take it for a small ride (if you can) and get it good and cleaned out. THEN see if its still smoking bad. Also, depending on what oil youre using it could have separated from the fuel in these cold temps

Dutch_Rutter · « **Reply #30 on:** November 27, 2013, 03:37:24 pm »

AHH the two stroke thing

Isn't two stroke smoke supposed to be blue? Maybe I'm just katarded and am loooking for things to fix. on idle it was speeding up by itself then it would just die. felt that was kinda odd. I'll be able to get a good ride in tomorrow and see whats up with it.

Time to invest in a leak down tester.

Chuckie25 · « **Reply #32 on:** November 27, 2013, 03:41:00 pm »

I smell a leak! Lol

Yeap time to make you a leak down tester

Dutch_Rutter · « **Reply #33 on:** November 27, 2013, 03:42:36 pm »

I'll have to build one and give-er a go.

Here's the best plan of action take about $500-$1000 and glue it to the motor and call it done, then sell it and tell any potential buyer you have $1000 in the motor and can show proof!! Save yourself the headaches!! Lol

Just kidding time to tear that biotch apart and figure out what's what!

GrkGuy · « **Reply #35 on:** November 27, 2013, 04:54:01 pm »

just try to run the bike, try to run a wide open through the gears.
check carb boot, for any tears, check both crank seals. i think bike is just loaded up with a bunch of un burnt oil.
do you try to mix fuel in the tank before you start bike.

Dutch_Rutter · « **Reply #36 on:** November 27, 2013, 05:04:45 pm »

Buckeye, If I cant figure this thing out that might be just what I do. LoL

GrkGuy, I hope your right, I can believe the un burnt oil because of how many times its been kicked over without starting. and then just eft to sit. Ill run it hard tomorrow and see what the end result is.

Just for my knowledge how can one check their crank seals? spray it down with WD-40 and check for dry spots?

GrkGuy · « **Reply #37 on:** November 27, 2013, 05:28:55 pm »

do you try to mix gas in tank before you start bike each time after it sat.

Dutch_Rutter · « **Reply #38 on:** November 27, 2013, 09:27:09 pm »

This last time I think I forgot. But I usually try to give the bike a good rock before starting.

GrkGuy · « **Reply #39 on:** November 28, 2013, 10:36:45 am »

well you gotta shake it good, i sit on bike and try to rock it back and forth, using the front brake to help get it mixed good.
you gotta think when gas settles the oil drops to bottom of tank, when you turn fuel on you either get a slug of oil or a slug
of gas, guess where that goes, straight to carb, guess where your having your problems at.

Dutch_Rutter · « **Reply #40 on:** November 28, 2013, 10:06:55 pm »

Ah now it is all making sense. I also really think that there was and probablt still is some unburnt garbage in that cylinder, I still havent had the chance to run it yet, Part of working security for retail stores around this time of year and having a life dont really coencide.

Dutch_Rutter · « **Reply #41 on:** November 30, 2013, 05:53:58 pm »

OK, so I took it for a run today. And from what I can say something is very wrong.. mid range is very chunky I guess, for lack of better words. I did manage to get the power band to kick in. In first second and third but the bike was really hesitant and it never got past the chunky midrange in fourth. After getting it running it was not smoking but it would on ide, even after running it. I plan on taking it in on Tuesday unless we can get it fixed before then. Any ideas?

Chuckie25 · « **Reply #42 on:** November 30, 2013, 07:08:33 pm »

What do you mean by chunky?

Like loaded up real bad? Or acting like it was on a rev limiter? I have a video of mine where it was suuuuper loaded up when I took off I could post if you wanted?

Dutch_Rutter · « **Reply #43 on:** November 30, 2013, 08:58:22 pm »

I will upload a video of it running tomorrow. Its really odd and hard to explain. I'll just throw up the go pro and give a quick run so you guys can see first hand.

Dutch_Rutter · « **Reply #44 on:** December 01, 2013, 01:58:02 pm »

So I went out to take the video, and it won't stay running right. Now its running away off idle and dying like before. I think I'm throwing in the towel on it and must take it into the shop for a full inspection an probably an overhaul.

Chuckie25 · « **Reply #45 on:** December 01, 2013, 04:31:57 pm »

Ok I'm gunna put my money on the clutch side crank seal.

Save a lot of money and do the work yourself bro!!! We can talk you through it or of you get yourself a manual you can learn from there. It's suuuuper simple stuff

1986QuadRacer · « **Reply #46 on:** December 01, 2013, 04:55:36 pm »

Clutch side seal. Get one for ten bucks and locktite that suckered there. Smear a little grease in there too. A little oil and you'll be riding again soon.

Dutch_Rutter · « **Reply #47 on:** December 01, 2013, 05:33:10 pm »

Alright Ill give it a try. I have the book downloaded on my pc, so walk me through this.

GrkGuy · « **Reply #48 on:** December 01, 2013, 05:36:53 pm »

i guess a vid of it running would help us, even a cell phone vid could work, did you try it with choke on, how did it run with that.

Dutch_Rutter · « **Reply #49 on:** December 01, 2013, 06:56:34 pm »

ok, I'm in the process of putting a video up on youtube, (SQHC isn't liking me right now) Its a short vid of it idling and speeding up with no throttle or choke, and then dying. it is a cell phone video so it kinda sucks but you can at least hear how its running. there is a lot of dark oil coming out of the cylinder, and white smoke when idling, but only when idling.
