250F 2002 CR250R Top end rebuild thread

jeremymach2015 · Jan 23, 2012

So my bike was in need of a fresh top end so i ordered the supplies, have never done one before but i thought how hard could it be, so far so easy, here's some pics, i do have a slight problem though....
I started by taking the seat, shrouds, number plates, and tank off

shes lookin a bit dirty, but I can still work with it

when draining the radiator fluid it shot out and went everywhere, and soaked my hoodie..

then i got the radiator hose off, but when trying to get the brackets that hold the cylinder head in place, there locktited up, and wont budge, so I'm gonna have my step dad try to help me with that
and got the new go pro mount goin vvv

more to come ....

well hopefully you man up and get the bolts off, keep us updated

put some heat on those bolts and nuts and that Loctite will break loose

good deal on getting it done on your own :ride:

and if you need help, Mike will make house calls as long as your Mom is home :smirk:

This^^^^^^ In fact, I've been known to toss a bit of heat to my nuts but, I never, and I mean never, add any Locktite.

jeremymach2015 · Jan 23, 2012

this guy that owned my bike liked to use locktite a lot from what i can tell, but at least i will never loose a bolt though lol

Good "Jerb" Jmach.... Hell all this time i thought you were just a 15yo skater punk... :stirthepot:

jeremymach2015 · Jan 24, 2012

well got them brackets off with a very ridiculously large wrench

then i took the cylinder head off carefully, don't mind the finger smudge kinda by the center, thats not a scar lol, from your guys experience how does it look?

then i got the exhaust and pipe off

After i took off this i shoved a clean rag in there

more to come tommorow
