okay. so ive been holding off my top end rebuild for way to long.spring around the corner so im gettin er done.my cylinder walls are scraped to shit, not deep though, and same with the pistons. i have a few optioons in front of me and maybe more i havent heard.

please tell me the best option.lol.

option number

1.open it iup see if i got more room to bore, and then what. order the next size piston kit. send it to a mechanic to do what. i dont need to send the whole bike.. then what,how is it instralled after.???????

 

option 2. buy the cylinder sleeve kit with gaskets,pistons and everything. send it to a mechanic to get installed?????

 

option 3.buy a whole new cylinder kit with pistons gaskets etc..... ebay is cheap.

 

option 4,try just honing it amnd using the pstions if the compression is good.

 

what should i check for when i open her up.(my mechanic buddy will, but hes no pro,but does this all the time)but i wana make sure everyting is good. no metal debris floating around in lower engine, or wrecked crank, please give me some pointers on how i should go about a top end rebiuild. i use ebay and can get kits for around $4000, sleeve kit, cylinder kit,.maybe less if used without the kit.

 

 

 

Id also like to know what a mechanics process wil be for these options, epecially the sleeve option, i like the sounds of that, get a big bore kit.

You need to call a reputable builder and send your cyls to them.

 

They will bore them straight and supply you with the piston kit to match.

 

Buy a clymer's manual and reinstall when you get the parts back.

what do machanics do for when the instal sleeve kits to cyliders. i may want the vitos 404 kit.

R u on the last bore of ur cyls? If not its a waste to re sleeve a set with bores left. If you want a big bore that bad, send them to a reputable builder as stated before. Putting it together is simple, but tricky also. Ring gap, ect. Make damn sure u lube EVREYTHING with ur premix (crank, bearings, wrist pin bearings, cyls, ect) Good luck, let us know what u decide.
