KEVSWS6 Posted April 17, 2009 Report Share Posted April 17, 2009 You still have a problem somewhere. That thing should not have 170 mains or the needle all the way up. That should be so fat it stumbles on itself. Quote Link to comment Share on other sites More sharing options...
shanYE west Posted April 17, 2009 Report Share Posted April 17, 2009 Was a leak down ever done on the motor? I saw it was on the "things to check" list but looks like you started messin around with other stuff first. Quote Link to comment Share on other sites More sharing options...
sheefreak Posted April 17, 2009 Report Share Posted April 17, 2009 They mentioned they did one a few posts back Shayne. I am w/Dave on the coolant leak. I had that issue last year and sure enough, had a pinched o-ring. Did you try tourqeing the head before the cylinder base nuts? If your head is slightly warped, this will help.

nitrousbaby Posted April 17, 2009 Report Share Posted April 17, 2009 (edited) yea a leak down was done and it held fine.... so you guys are thinking its a electrical issue then I will change out the cdi with a good one(that I know works). we did not pull the head last night but I see no evidence of a coolant leak. Ill pull the head tonight just to make sure though. Edited April 17, 2009 by nitrousbaby Quote Link to comment Share on other sites More sharing options...
sheefreak Posted April 17, 2009 Report Share Posted April 17, 2009 If your pipes are sealed well at the flanges it is hard to see evidence of a coolant leak. All it takes is a minor seeping of coolant to dilute your fuel mixture and you have deto. One other indicator of a head leak, but usually a bad one, is you may sometimes get a kickback when trying to kick it over. Quote Link to comment Share on other sites More sharing options...
2strokespirit Posted April 17, 2009 Report Share Posted April 17, 2009 Just plug in another CDI, much less work then removing the pipes and all to remove head, if its not the cdi, then there is a coolant leak or vice verse... Quote Link to comment Share on other sites More sharing options...
Detroit Muscle Posted April 18, 2009 Author Report Share Posted April 18, 2009 Another update. This afternoon first thing we swapped out the cdi with one from another bike and then we fired it up with the 170's still in it and the needle still set all the way rich. It sounded completely different and barely ran. Then we set the needle back to the center notch where it was originally and tried it with the 170's still. It was better but still boggy up top so I stepped all the way back down to 160's and then ran it and it seemed much improved. Now we've reset the timing to +4 and everything seems to be good. It's supposed to be nice out and warm tomorrow so I'm gonna run it for a while and see how it acts. Hopefully we've solved the issue. Thanks for everyone who's helped, and especially to Kevin who's spent a ton of time on the phone with me since building this motor. Quote Link to comment Share on other sites More sharing options...

nitrousbaby Posted April 21, 2009 Report Share Posted April 21, 2009 Well we took it out and it seems to run like a raped ape! ... Kevin, I never did speak to you personally but I just want everyone here to know that you have my reference ANYTIME! Ive delt with alot of builders that if there is a problem they let you sink or swim once they got your money... But you stuck with walker the whole way till it was solved and I know it had to get anoying a bit being on the phone that much. Just want everyone here to know that I have never seen customer service like Herr Racing gives. oh yea and the most important part the motor hauls A$$! :biggrin: Quote Link to comment Share on other sites More sharing options...
