3TJ Timing with no rotor

[cbr400rrn]

If the ports are untouched i can't see it doing much more than stock. I'll PM you a very good setup when I get a moment. It will require the cams dialing in and a bit if stripping/rebuilding but will give you a very strong motor with power output below 140000rpm.

You should also pre-load the valve springs by installing washers below the spring seat, keep the valve from jumping into bed with the pistons :-)

I know this is an old post but I’d be very interested in any set up advise you can send me, especially regarding cam timing. I’m a bit late to the party it just getting into racing an fzr.

Sorry but kiyoshi hasn’t been on here since 2016, hopefully someone else will help though
