How far should they be pushed in?

Do they bottom out against some thing?

Mine is about 4.5 mm in. I kinda thought it was supposed to be flush.

Gas Porting: http://www.wiseco.com/FAQs.aspx 14. What are gas ports and when should they be used? A. Vertical gas ports are primarily used in drag race applications. Lateral gas ports are more often used in circle-track and road-race applications where carbon build up can occur. When gas ports are u...

I thought the it was more about cooling the piston, but could be way off base on that one.

While you have the piston out try gas porting for better ring seal. I know that's been done with successes on the vertex.

Sold

yes they will fit

Any ride report? Sid you stick with a 10deg advance?

Once you go black you don't go back.

Why do you supose the 2000 250 and 125 CDIs timing curves each flatten out at about 12 degree in the higher rpm, while the others continue to decrease advance?

I would think the high rever like the 125 would just keep loosing advance till the bitter end.

I had some thin o-rings laying around, I put one of them on to center the pipe on the flange. stock ring would do the same thing.

this looks more cost effective.

I personally like Chamber-Seal. But, it is hard to find

I feel like obe won kenobi

Chamber-seal ... Now that's a name I have not heard for a long long time.

Where are you finding it these days?

Ultra black for me.

Do not know if they are any good of if the price is right, they sent me an e-mail because I have cr250 in my machine profile.

were 175 now 135

I don't need radiators, and prefer OEM, just putting this out there in case someone does

Worried about what I will do when I smoke my david bailey graphics. Would like to get a back up set.

Any idea how close the shroud graphics match the '02 cr250

'04-05 crf250
'06-09 crf250
'05 -06 crf450

Looks like the time serts are the way to go. The decomps have a 10mm x 1 thread pitch. Same as road bike spark plugs.... so looks like there are alot of thread repair options for that size. its sold by wurth. A copper style sleeve that has a broach to size it in place. https://bannedcr500riders.com/...

So I tightened a bit too much and stripped out the thread in the head where the decomp valve goes. Thinking some sort of insert style thread repair would be the ticket. 1) Any recomendations on which style insert to use and were to get? 2) Any idea on what thread pitch the decomp valve likely has? 3...

Did you mill out the swingarm bushings, or did you remove the 250F bushings and use those? I tried milling out some '88 bushings. They are hard as diamonds.

Billybob or Roosty, both use torque plates to my knowledge.

Has anyone checked. I know it is an issue with the 125. But just looking at my gen 2 cr250 it looks like it would hit. I know the gen 4 sh bikes hit slightly.

I would really like one that looked just like the OEM, but billet. The Service honda one comes to mind, minus the "service" and the "racing" although I could live with the racing. Considering getting one and tig up the "service"

Rocky mountain was great with the free shipping, but they no longer deal in OEM.

neat idea. i like my yz250 oring set up, but it is the cyl that is grooved, which i like better, then I can mill the head at will.

*might* only if you go slow on the filing, only taking the high spots off and STOP when you get to the lows.

All in all just get a new basket
