    2004cr 125 can A or B cylinder work with A piston?

    I just found a ( stamped on the bottom of the cylinder. My old cylinder has an(A) stamped in it. So now I am pretty confident my new one is a (.
  3. I just bought a new cyclinder the box is marked part# 12120-ksr-A00 as a ( cylinder. But my new cylinder has an (A) in the casting on the side. I have both A&B pistons. Can I use either one? The new cylinder also has BL9 stamped on the bottom surface that mates with the case. Doe anyone know how the factory marks the cylinder? The motor cycle shop says I can use either piston and thinks that the new cyclinder is an (A) in a ( box:banghead:

    gpx 150 (xy150)

    Kinda funny how that works out. I posted some things that were very true about a payed advertiser. Next thing I know my post are getting deleted. It makes sense to me now PM loses there payed BS advertiser and they no longer get there $. They have to protect the BS that goes on. Just my 2 cents. Oh no, they are here now too! LOL

    flywheel weights

    Thank's, I wasn't sure what was going on with 200 buck's for a flywheel weight. Shoot KTM's were even less then RM's. Thank's for the reply's.

    flywheel weights

    What makes the rm flywheel weights cost more then the other brand bikes? For most bikes they are about 100 bucks a rm it more like 200 bucks.

    BAD DAY! gas in my oil!

    3 weeks ago I went to ride to my kids soccer practice and I ran out of gas. I put some gas in the other day and she wouldn't start. So now after check the carb and spark plug, I find out my needle/seat o-ring is leaking.(the o-ring around the seat). I fix that, and still it would fire up but not run. OK, now I'm thinking I better just check my valves (I haven't done in a while). So, I go to drain the oil and . Man, to many variables! So yeah, kinda a bad day. Any feed back about what the next step is? I was going to put some new oil and run it for a little bit and then change it again.

    Brand X in the Sand

    Brand x is good out of the box. Try and get parts for the %^cking things. If this guy Chad is the go to man, he sure has some bad customer service. He wouldn't return any phone calls. Stay way from Brand x unless your going to keep it stock. It's been over 2 weeks and still can't find gaskets for the POS 107 brandxmini. And yes, I know it's like a SDG.

    Gas puddle on the shop floor!!!

    That's exactly what I did, took all the stuff off the rear to get to the carb to find that the needle and seat had a bunch of gooey stuff in it causing it to stick open. Thanks for all the in put from you guys!!
