G'day fellas.
I've been dreading the day when my bike needs a top end as I know BMW usually charges the hell out of everything and comparing rebuilds on other bikes I know it will be more expensive and time consuming as the engine is ridiculous to work on for space.
First of all has anyone done theirs and to what lengths did you go to?
I'm the type of bloke that if its going to cost me a bit anyway I would rather spend a bit more to go the extra step. I'll be replacing the exhaust valves with stainless for piece of mind.
I was looking into a higher comp ABC piston from Vertex in a 492cc big bore kit. Obviously I know I have to have the bore done etc but anyone thought of doing this? I was told the 511 runs slightly lower compression to the 449 but couldn't find this anywhere. I was hoping to up it from 12:1 to 12.8:1. The vertex piston with rings is much lighter than factory which will let the bike rev cleaner and with the higher compression I would think it would absolutely anihalate a 511 but keep the racier feel of the 449.
It will be ran with a FMF Ti Megabomb header and Ti Factory 4.1 slip on. A JD tuner will be purchased afterwards to confirm with JD jetting my mods.
Any info will be muchly appreciated!
