83 250r Locked up PICS--*FIXED!

[smyers33]

Is this the piston I want to order? http://denniskirk.com/jsp/product_ca...007&mmyId=5899

still kinda hard to tell, but they dont looked cracked, do they have small visable cracks in them?? if so ditch them for some new ones, sometimes you can flip them to get more life out of them.

[SYKO]

what over bore is that?? my local cycle shop sells pistons to me alot cheaper than dennis kirk sells them, slow down alittle and go out and get some more info from some decent shops, before you blow alot of unwanted cash, I only paid 85 bucks for my .80 over 85 250R piston, and its lists for about 125 in dennis kirk so.. do the math.

As long as the reeds are not ripped or fraying there should be a spec in the manual for allowable lift of the reed from the reed block measured at the tip of the reeds (zero is ideal).

I can barely fit that razor blade in the gap... I think they are fine.

If your local shop can't give you a good price on a piston, there's a guy on ebay, sledpartsguy, he has wi$eco piston kits for like 80 bucks. I just bought one from there, save some cash

Well I placed the order yesterday (1/9/07), and got the .20 over piston kit from the guy on ebay. I also ordered top end gasket set, and and outerwarez for my air filter from denniskirk. I'm hoping to get it by Friday, but I don't know. Now my question is, do I just use gear oil to flush out my bottom end, and do I just put the oil in the fill spot? Or can I put oil down in where the crank is showing? I hope to have it rebuilt by the end of this weekend. While breaking it in, what steps should I take? I have a NGK BR8ES ready to go in, should I go with a BR9ES? I know the 8 is hotter, so I don't want it to seize again. Sorry for all the questions guys, but I don't want to screw anything up!

[toocheaptosmoke]

I would use diesel or kerosene. Pour it into the crankcase, it is sealed off from the transmission.

I run the NGK BR9ES or B9ES in my R never had a problem with it. In the tecates we run the 8's. I think it's up to you, but I would stick with what honda calls for, the 9's.

Those reeds are aftermarket. You can tell because of the stops are removed. They look like Boyesen Power reeds. If you replace them or take them off for any reason, use Locktight when putting the holding screws back in. Just make sure the top reed is easyer to open then the bottem. Check with a screw driver. The manual calls for a stock B8ES NGK. Stock main jet calls for at least 158.

Has anyone else tried the diesal or kerosene? Does it still drain throgh the drain plug in the bottom?

[SYKO]

no you have to pul the motor out of the frame, the drain plug underneath is for the trans fluid, you will have to tuen the motor upside down to ge the deisel out.

Had family visit from Ohio this weekend, so I didn't get much done. I got the motor loose, and ready to come out. Now, do I have to take the swinger off to get the motor out? I assume you do because I've tried to move this motor every which way. Still waiting on my piston...

[smyers33]

I got my cylinder back today, and they did not chamfer the ports, but they told me that it will need to be done before I reassemble. The owner told me just to take some fine sand paper and go over them till they are rounded a bit. Another worker told me to use a rattail file. Will either work? I think the file will take too much metal away but I dont know. Let me know which to use. Thanks
