Default 01 Cr250 Watch Video Please

     

Hi guys and girls,
It seems I'm having an Idle issue or possibly something more. After some warm ups and easy riding and and oil change my idle is still high and seems not right. The bike seems to have power and I am at 32:1 with klotz. The idle has been high since the rebuild.. I assembled the motor with grease in the pinion joint area. The power valve (CRV) seems to be functioning properly. I haven't done a leak down test/compression test. I installed a new OEM stator and haven't properly timed it correctly. (Going to get the light / tach on Tuesday) At the end of the video can you tell me what that "bird like" noise is when shutting off the bike.

Again thanks in advance

Ken

Check your float height and adjust accordingly before dorking with the jets.

Don't rev the crap out of it until you get the fuel mixture correct. Lean condition can cause motor damage.

Ken, have you done the carb conversion on this bike? the mukunis were a huge problem for this bike. Check the float bowl height and see how that works. Im sure you tried turning the idle down....right? . Also a chipped or cracked reed will cause similar symptoms. Hope this helps.

I have not done anything to the carb except clean the outside of carb. I did check the reeds but only briefly. I will turn down the idle screw after i re-check the reeds. Any idea what that whistling noise is when shutting bike off? Is it a sucking air noise or new seals wearin in? Lol. Anyone?

Sounds good. Keep it simple and I'm sure you'll get nailed down. It's weird, it almost sounds like the high idle when the choke is on.....Let us know what you find.

I tracked down that bird noise I was hearing and it was coming from the cylinder to case gasket. I loosened it up and re-torqued it to 29lbs and the noise went away but there is still a slight air leak. I put my finger over that area and the idle come's down. I will be timing it up tomorrow. I messed with it today but i need to elongate the bottom setting plate. At 3000 rpm the f marks are not properly lined up. ( i seen a post from dogger, he was replying to a post from 2009 and dogger stated it should be timed at 5000 rpm. My manual says 3000 rpm. Did they supersede that rpm>?) anyway here is my vid from today's progress. Still not perfect but way better than yesterdays vid..
