    agreeded, new bike coming soon, :D
    I've got 60,000 on my TC88, should i start worring about the rod bearings? But then I don't know of anyone who's rod bearings have gone out.
    Between replacing starters, working on the truck, having his appendex removed and being on Bike talk 24/7. I am just wondering when he had time to put all those miles on.

    If you buy quality tires and keep the inflation pressures right you should.

    Pretty much a hot rodder, yep about 10,000 miles per rear tire, and can do 700 plus miles in a 14 hours, and we have 75 mile per hour speed limits.

    just hard timing ya, :D

    CB When he said you should have done higher compression did they say how high. It seems alot of people complain about getting good fuel with the higher comp. engines. Just curious.

    He liked 10.5 to 11.1 or so. More compression than 9.81.
    He also said instead of the flat top pistons I had he liked 20* raised Dome Weisco pistons.
    All this changes according to what kind of build he's doing for you and what kind of cam you are installing.
    Don't think there is nothing set in stone. Its about the Build, cams and compression to what decesions are made.
    I picked his head as much as I could.

    CB,

    I really hope that you have access to 98+ octane to run in your bike if you are going to go with 11+ cr? That is ridiculous to go that high. 10.5 From everyone that I have ever talked to and including my own research from when I built my high HP car engine, all indicate that 10.5 is about the highest you can go to be able to run on regular pump gas.

    I know you do not want to hear this, and again, I do not know what kind of access you have, but E85 has an octane rating of over 100. Another option is to install water injection that utilizes 50% water and 50% methanol. Just a suggestion.

    Do you believe in octane boosters?

    Its in the tune and you use compression realeses to crank the bike.

    Detonation has nothing to do with compression releases and fuel mix to compression of the engine....

    Got a guy building 124 motors with 11.1 compression ratio on 91 octaine pump gas and they are running fine.
    He also build race engines, think he used race fuel in them oh. Seen the cans.

    Got several other friends with S&S 124 motors and build 124 motors runnin 91 pump gas.
