New Piston, What should I expect???

[MikeCR]

I have 97 CR250, put a new piston in it, and got the cylinder honed. Started up in one kick. Now here is my question, I am going out tomorrow riding for the weekend, What should I expect??? I am noticing a lot of smoke even when warm. I don't have to rejet as the jetting is perfect. Thanks

might be a place to start - - dide you wash the cyclinder out after it was honed and wipe with a soft rag and some type of light oil untill it was "clean enough to eat off of" just quoting a previous thread from on here. just asking.

"started up in one Kick".. Did you go through the proper break-in procedures? Here's a link for any questions.

Engine Break-In

I just finished a top end and followed this and have had no problems, and no excessive smoke. Did you do the hone/piston replacement? Did you check the bore size/ring gap etc.? If you do a search you should find plenty of previous discussions on this topic. Good luck.
