I really seem to be going from one upgrade project to the next lol
Next on the list, I need to lean and do a top end.
For the most part, this looks very doable for me.
Picked up my 2012 250X six months ago, and was told it had 25~30 hours on it (take that as you will) this was the 6th of June 14.
Since then, I've stacked 75 hours, and a month of that I couldn't ride with a bad ankle.
For now, the bike is running great, oil burn is fine, no blue smoke, power seem fine etc. etc.
But, at 100+ hours today, and the amount I ride, it's only a short matter I've time till I'll have to.
But I have a few things I need to understand.
1: CRF Only sell's a JE Piston Kit http://www.crfsonly.com/catalog/product ... ts_id/1344
that has a higher compression ratio but says it fits the standard size bore.
Will this fit the stock cylinder without any mods, or is there more to it ?
2: If I'm pulling it apart anyhow, I should look at changing to stainless steel valves (I had to shim mine right after buying it, which makes me not trust the hours I was told, good since though, but I don't rape my gear)
Crazy as it sounds, I can buy a new Head, stainless steel valves and the valve seats cut off CRF Only for about the same as just having the valves changed here lol.
So maybe change to an R head, and just order the whole thing off Ken http://www.crfsonly.com/catalog/product ... ts_id/3139
Even a Cam change is on the table at this time, just need to understand what I can or cannot do, and where it may help.
What I'd like to achieve.
3: A piston change done by me, top of the list
4: Don't make it harder to start (it starts real easy now, I want to keep it that way)
5: A little more power everywhere, why I’m looking at the JE piston kit over the OEM
6: I ride ALOT, stack hours, stainless steel valves will be needed sooner or later. So do it now when it's all apart.
7: Cost here, means a Head change can be looked at, But I have No idea where that helps in the power range, if it's everywhere, cool, if it's only top end, don't really need it.
8: In order of where I'd like a little more power would be in this order, mid, bottom and top end is last.
9: Between jumps and out of corners a little more pick up would be nice (riding better and holding more speed would also do it, but thats not going to happen anytime soon lol)
10: And if I'm making a wish list, being able to hold a taller gear on some hills would be nice with out changing the gearing.
The above is a bit long winded, but if you know what I'm trying to do, you will be able to help me better.
Thanks for your time
