Thread: Look what I did to my 250r frame! I plan B'ed it
Started 3 weeks, 2 days ago by Kintore
Well, guess im riding this thing to its full potential. Tearing it down and found this- Glad its the end of the season and no more of this!
Going to get my 85 frame all guessted up before I PC in a few weeks. Getting all new metal bars and supports in the frame neck area and long bar or tube of metal around the downtube.
Judging by the haspin clay I can assume this happened at TF on ...
You should have no problem changing the plug. I have a Pro-X cylinder with a billet head and I can get it out pretty easily. I didn't have to mod the frame at all.

why not fix that frame.
cut a section out. weld in an internal tube. rewrap and rejoin. and then weld a piece of 3/8 solid tube down the lower section and upper.
seems like the potential exists to beef her up.
I broke my frame in the same place, I had it fixed. Some months later, it broke there again, 3 other majors on the frame and around the footpegs. Thats when I decided to have a frame made for me, that I won't break. With that cool-head on a 85 frame, its gonna be hard be able to get to the spark plug.
Yes, repairing the frame will work for a short time. The problem is, that part is gonna be stronger and the next crack will move to a different part of the frame. What will happen in the new part will crack(my case was left side downrails to the pegs) and it will re-break the center tube also. That frame is junk and as he said, there is more cracks around the frame that need to be repaired. ...
thanks a ton guys, im going to try and make a normal plug work. IF not I really appreciate the help on the peckerhead plugs lol Yah, its pooched boys. Think its going to PA to hang on a wall with a picture of a Canadian flag under it!
"BR8ECM" The B is a 14mm thread diameter. The R isa Resister type construction. The 8 is the heat range. 2 being hot and 11 being cold. The E is the thread reach. E being 19mm or 3/4in. The CM is firing end construction. CM being compact type, low angle ground electrode "BR8ES" The ES is firing end construction. ES being Standard 3/4" thread reach 2.5mm center electrode
Isn't that cute, its like a spark plug but only smaller. ROFL! I'm glad I can just get the readily available BR8ES and it fits. Good luck finding that little sucker at the local parts store. John
Here ya go, not sure what other heat sizes you can get, heres an example of an '8' heat range {BR 8 ECM} If you want an Irridium its {BR 8 ECMIX} Heres a pic of what the short lil peckerhead looks like. Im not sure, but you may have to run a special boot for it, i wrote down TR51225 for a cap, but im not 100%

Nice info guys, never knew they existed. They're a bit pricey though, I did a quick search on Ebay and found them for about 1/2 price if your interested. http://cgi.ebay.com/ebaymotors/NGK-S...item3a543f042e
