1999 Rebuild, It's time to make some power!

Post by caseyracing222 »

Well I blew my rear shock out last race and I've been waiting to tear this thing apart for a long time and finally got to it. Im going to order new reeds and send my jug off for porting along with my head and carb for some machine work. I didn't get to far today because I no longer have a torque wrench at the moment. I will be grabbing one from work tomorrow and I will pop the head off so I can measure the squish. anyways heres some pics from today. This is the first time this bike will be rebuilt.

Why do you need a torque wrench to dissassemble it?

I need it to torque the head back down to measure the squish. I will take the head off lay a piece of sauder following the wristpin, torque the head back down give the piston one rotation then the machinist will know how much squish there is. Thats why I need the torque wrench Bob.

Smart move....

As far as the torque wrench goes... You can reuse your "allready crushed" head gasket to make your impressions with and the head torque really dosent make a difference.

Torquing the studs just stretches them, it wont make the head any closer to the piston.

Exactly what I thought and was going to do Bob, but I decided I better do it the way my guy wants me to... It's only a day delay. I went out in the garage and tinkered some more and got the radiators off and the head, then popped the reed cage off, surprisingly theres no cracks and it looks good from eye ball perspective but only measuring instruments will tell. I'm leaning towards re ringing the stock piston if the bore is good or getting another OEM piston? any Input on that would be great, Im not using a Wiseco though...

do it how your guy wants :cool: . i just use 4 bolts and tighten with end wrench, dont give a crap if its the right torque. pretty much what bob said. doubtful youll see a .002 difference with/without torque wrench. .002 wont make a shit bit of difference :lol:

cool. i dont know him but heard of him. seems like a good rider. nothing wrong with using a torque wrench. i done it both ways and found very little difference so i dont bother with the hassle anymore.

Yeah theres quite a few guys that have a motor built by him, they make good power (seat of the pants) I'm not sure about on the dyno.

Ok I finally got time tonight to try and find how much squish I have, it didn't go so well, I dont think the sauder was thick enough, it didn't squish at all. I was using .120 thick I'm going to switch to lead and use .200. anyways heres a pic of how I set it up, after this I set the piston at the bottom of the bore and torqued the head on and gave it one slow kick so the piston would only hit once. Any suggestions on if I should do anything different? It would be cool if Adam chimed in or someone to his knowledge about this kind of stuff. :D

dollar store quality funtac, squirt a little wd on the chamber, brake kleen the piston, funtac on the piston, strait above the wrist pin. roll the piston thru and pluck the head off it. :wink:
we use funtac every day, valve clearence is the most common place

never heard of it. does it dry up and shrink ? pete may want him to send it with the topend so he can measure himself.
