colby72olds Posted August 6, 2008 Report Share Posted August 6, 2008 I had my shee jetted rich just to go through some heat cycles. I let it idle for about 20 min. I came inside for about 10 minutes and when I went back outside, there was coolant all on the floor (came out of overflow) and oil shot out of the right silencer all in the floor. I took my plugs out and the right side looks WAY rich and the left looks decent (I was doing a plug chop and I broke the right plug, so..no pics). I took my water pump cover off and only about 4 ounces of coolant came out. I tried to spin my impeller and it wouldn't, is it suppose to spin freely? It's the stock impeller btw. Do yall think I blew it up? I'm so bummed, I've been building it since December and finally got my jets in the mail today. :shoothead: I wanted to see what yall though before I take the head off and look at the pistons. Gol, I don't know what to do. :sad: Quote Link to comment Share on other sites More sharing options...
THE GRIM RIPPER Posted August 6, 2008 Report Share Posted August 6, 2008 Can you kick the motor over? sounds like your water pump impeller just failed bigtime Quote Link to comment Share on other sites More sharing options...

colby72olds Posted August 6, 2008 Author Report Share Posted August 6, 2008 Well it was running about 25 minutes. It was fine for the first 15 minutes. Should I try to just replace the impeller, or go pull the f***kin engine again? Quote Link to comment Share on other sites More sharing options...
C&B Posted August 6, 2008 Report Share Posted August 6, 2008 (edited) Every she on the planet needs air moving through the rad. The litlle teeny impellar cant do that at an idle for 25 min. The impellar wont move with youre fingers it connected to the crank (ie, the white gear on the back of the impellar). Just check the comp. make sure it all good, and never EVER do that again. BTW, jetting rich will get it hot faster, just like lean. Edited August 6, 2008 by C&B Quote Link to comment Share on other sites More sharing options...

He's right do the comp check, sounds like it just overheated and your carbs arent synched. Shees can't idle that long. Quote Link to comment Share on other sites More sharing options...
colby72olds Posted August 7, 2008 Author Report Share Posted August 7, 2008 :sweat: Dang, I hope you guys are right. How does everyone do heat cycles if you can't let it idle for that long at a time? Well I sold my pipes just a second ago, so I will have to wait to check the compression...dangit it gonna bother the crap out of me. Are ya'll almost positive it didn't blow up? I can still turn the engine over. Would it blow out oil just from getting hot. Thanks so much for the help guys, I've been worries sick. :cool: Quote Link to comment Share on other sites More sharing options...
xXBlessedWithDeathXx Posted August 7, 2008 Report Share Posted August 7, 2008 when my motor was built we did a few heat cycles 3 maybe then re torqued the head. after that in was donuts in the alley. that was about 1 1/2 years ago and i`m still on the same build. i think your good for the most part .

colby72olds Posted August 7, 2008 Author Report Share Posted August 7, 2008 how do you do heat cylces? you RIDE IT!!! holy fuck... are you serious!?!! ride it for a couple mins.. shut it off.. ride for a few minutes shrt it off.. keep doing that for about an hour or so... and you dont want to jet it rich, just mix the oil a little heavier, also make sure u arent using a synthetic oil otherwise it wont break in properly.. once it has ran through the first tank of that gas it should be pretty much fully broken in My bad dickhead Quote Link to comment Share on other sites More sharing options...
colby72olds Posted August 7, 2008 Author Report Share Posted August 7, 2008 well it's blown up for sure...60 psi on the right, 30 on the left :: I learned my lesson. This ruined my week for sure. Quote Link to comment Share on other sites More sharing options...

fox_forma Posted August 7, 2008 Report Share Posted August 7, 2008 are you running a cool head or anything? Make sure it is on correctly and the o-rings are seated. I went through this issue with mine and sold it off for a milled and re-chambered head. O-rings were just a PITA to get seated for some reason. Your going to have to pull the head either way so see if you burned a hole in the top of one of your pistons or possibly seized a ring.

colby72olds Posted August 7, 2008 Author Report Share Posted August 7, 2008 Nah, just factory milled head. I've already pulled the head and jugs, the pistons would move a little bit side to side but look fine :sad: It's my first two stroke. Everyone has always told me heat cycles are letting it idle, cool down, idle, then let it eat. I know now. I guess this is a major (depressing) learning experience. I'll be getting a billet impeller for sure this go around and not let it idle so long. Thanks to everyone who gave me advice. And to speedy for just trying to make my day even worse :shrug:, guess some people are just assholes. Quote Link to comment Share on other sites More sharing options...
