I think a falicon is bling for this application but shifts more to mandatory when you go high compression, bigger bore, stage 2 cam etc.

i follow you. I will more than likely do the same. Doesn't the Pro-x have a bearing on the small end also? that seems like it makes more sense to me than it being a plain bearing, but what do i know?

list of bearings and seals that should be replaced while everything is apart? It seems that my online OEM parts list is growing up over $400 for the build, and it probably really does not need to be. thoughts?

Many of the smaller bearings, as in the clutch rod lifter, etc, do not need to be replaced since they don't spin much.

It seems like I was into it about $400 for bearings and seals also.

it seems rediculous to spend $75 on the crank bearings, how can one bearing be twice as much as another?? crazy!!

I sold several of my Winter project bikes teh other day, so i came across some $$ to burn, but i thought it would last longer than one parts order, not including the valves or connecting rod! I have all the head cover bolts on the list to replace since last time i had it off, one broke and i'm sure others are close to life's end. those add up too. I have the cam tensioner on the list, and also the cam chain guide, no signs of wear on the guide, so i might remove it from the list also, shave $25 there. what about balancer bearings??

[mitchn06]

couple questions:
1. on clutch basket there is slight wear on the posts from the springs for some reason. is this "normal"
2. slight wear on the clutch basket again where the fiber discs ride





3. cam chain guide, what is considered wear? the darker spots on the guide? it feels fine and not sure if replacement is required.



random morning shot before work


4. cam chain tensioner arm, how do you tell if there is wear on this part, it looks fine and feels fine, but i didn't snap a pic.

5. i've already posted this in the main thread, but i've made up an OEM parts list that you can find HERE

oh, and after the last week of slowly taking engine out of frame and borrowing an impact and buying sockets, i got the case split, but now i need to have the crankshaft pressed out of the case, unless somebody would like to share a trick to do so.





transmission

got some more progress done today, i cleaned up quite a few random parts, took apart thermostat housing and tested thermostat, pulled swingarm off and suspension, pulled rear fender and subframe off. Also cleaned up frame and swingarm WD-40 and a couple rags does wonders, little bit of scrubbing also, but the WD really breaks it down quickly. and some pics.........

Thats great you are putting new life back into your bike!
Wondering what do you think accounts for the badly worn out top end?
Lack of valve adjustments, lack of clean fresh oil?

Good luck with your build, looking forward to hearing more.

I wish i could tell you a definite answer. i believe it to be lack of oil, but i only had the bike one year before i had to replace the rockers and cam, so it could have been from previous owner neglect, or because i wanted to ride more than i wanted to maintain, but i'm not totally positive.
