time to rebuild again


MILO

Recommended Posts

i've hardly had my shee out this summer or been to the site much. i've spent more time on the street this year. i recently traded my cbr600 on an '08 yamaha r1. pretty much all of my free time has been on it instead and the shee hasn't seen much more than the yard until this past Sunday. i went for a rip with some friends and took the shee, and what do you know, the rt piston ended up being toasted. the ring gap is now at the front of the piston, piston chunked up and cracked down the skirt, and caused enough debris on top to chew up my noss head dome. it doesn't appear to have let anything down into the crank though, but i'm not 100% sure. luckily it's almost like the last time when my left piston let loose and i rebuilt in april '06. anyway, here i am with an excuse to make some changes. here are my thoughts.

 

required:

- most likely bored due to a gouge in the cylinder wall. (just needed honed last time)

- new wiseco piston kits

- new noss domes due to damage from debris

- of course new cylinder base and noss head gaskets

 

now here's the extras i'm considering while i have it apart.

- advanced timing with RS or Pro Design plate

- changing from 20cc domes to 19cc domes

- crank trued & welded

- porting (probably woods port) since i mostly trail ride

 

questions:

- am i on the right track here? i already have PC pipes, noss head, v3's, hinson basket / tusk clutch.

- how much am i looking to get into here ($$). i'm assuming around $300 or so for the required fix, and probably around $600 - $800 to go with the extras. does that sound about right?

 

i'm probably going to tear into the bottom end myself if i go that route. i'm sure that with my clymer's, i'll get through it fine. other than gaskets and crank bearings, what am i missing, or what should i do or not do??

Yea that sounds about right. I port job will make a huge difference. It is the next big gain after pipes.

 

You can get a nice billit plate from chariot performance for a good price. Better than the 90 bucks for the PD, and better quality than the RS cast one.

Look up kevin from herr jugs racing for the porting if you want a geat port job and a great price with a quick turn around. He will also be able to do the bore and hone.

i was leaning toward herr jugs racing already, but thanks for the suggestion. it's good to know that others approve of and support their work. i'll probably ship my crank along also to get trued & welded. i'll just have them go the whole 9 yards on it rather than mix and match with different places.

thanks bud. i'll get in touch with you when i'm ready to get the work done. the top end is already stripped and i'll get the crank out as time permits. it may be a few weeks but i'll definitely be getting back to you. :beer:
