Finally had the courage to split the cases

[YAMAHAULER]

decided to start tearing into the original 02 motor that blew last winter on me so I split the cases and this is what I found...

Sooo as money permits I'm gonna start slowly building up this puppy and in a year or more the ol 02 will be going up for Elite hopefully.
so looking for some good aftermarket parts for the motor thinking of going .040 over and throwing a stage 1 hotcam not sure on valves and not sure on rebuilding the stock crank or going to a HotRods crank?
feel free to throw me some input and parts if ya guys want lol seriously though!

 

[duneracerweston]

Rebuild the stock crank, send it to mrcrankshaft, Vince will do you up nice! Its cheaper then a hotrods and he has alot of experience with warrior motors

 

[Gen1Pat]

Agreed^^^. It's that or a stroker crank.

 

[YAMAHAULER]

I'd like to do a stroker but at around $600 in just parts(from what I found on ebay)
and thats a HotRods +4 stroker rod & crank, 379 stroker big bore piston, gaskets, stage 2 hotcam and that's not including the valves,springs and rockers,P&P,bore & hone,so I'd probably be looking at around $800 to $1000 when it's all said and done it sure would be nice.:evilface:
but I think I'll just stick with my original plan rebuild stock crank, .040 over 10.25:1 wiseco piston kit,S1HC, mild P&P and a pair of Kibblewhite Black Diamond valves and springs:tup:
Let me know what you guy's think I'm open to input and good or bad part brand choice

 

[YAMAHAULER]

so here is my parts list for the build
I'm gonna have the stock crank rebuilt my atv shop that I deal with here they will rebuild it for under $130

let me know what you all think good, bad ugly? all opinions welcome need the input this will be my first build and I want it to last I want her to have a bit more BARK but without breaking the bank.

 

[duneracerweston]

Go wiseco, the namura wont hold

 

[YAMAHAULER]

ok thanks Weston how about the rest? anything I'm missing?

 

[ba9801]

I have the wiseco piston and KibbleWhite Black Diamond valves, springs & retainers.
I am also running an HMF exhaust.
I think that that combo works good on my bike.

Well hauller, what is it your wanting to do with this motor? What are you looking for power wise?

 

[YAMAHAULER]

I want to keep her reliable yet have a good noticeable power increase when needed

 

[YAMAHAULER]

Yeah she shredded one of the thrust washers and blew the connecting rod bearing

 

[88WarriorBoy]

TOTALLY FIXABLE with a little bit of duct tape and JB weld and maybe a clothes hanger hear or there :lmao::beat:
