cb450 > cb500t hybrid – part 3

2021 update – click here. Below is deprecated info…

I’m dubbing this the ‘cb475’.

I’m all finished and it runs fucking awesome!

I had lost interest with this cycle, but now I’m psyched on it again.

I’m super pumped on how smooth this engine swap went.
Pretty sure there aren’t many cb450’s with 500t engine’s around, so I feel good about this.
I’m gonna go ahead and say it’s a little faster due to the 50cc more and the extra torque.

Biggest difference I notice is how much tighter the tranny is. Apparently this is one problem on the 450’s that they upgraded and fixed for the 500t. I notice the difference, no questions about it.

cb500t – boom.

Cut the tail-light mounts off. Fuck that shit.

Removed my starter. Kick start only now. Don’t ask how I plugged the hole… It’s a bit south philly ghetto. ha. We’ll say a huge washer and JB weld was involved. ha.

Upgraded to modern fuse.
As I said earlier… my wiring is super streamlined now.
I only have 1 switch. The bike is on or off. No other electrical shit at all. Minimal wiring is cool. Thanks to Adam for the help!

Removed the dummy lights.

New throttle. No electrical shit.

New clutch perch. No electrical shit.

Brapp… cb475 in action.

So, to re-cap. This is everything I did in a month timeframe:
– Took cb450 engine out
– Spot painted frame / mounts / rusty shit
– Streamlined wiring to a minimal style harness with only 1 switch. New style Fuse.
– Swapped over charging stuff from 450 engine.
– Put 500t engine in without scratching the fresh paint… kinda
– Did cam chain / timing on engine
– New lever / throttle up front
– Took out dummy lights / horn / turn signal stuff / safety shit
– Went through carbs again / oil change / new plugs and shit

Adam and I are calling this look “OEM Plus” because the bike still looks stock condition, but basically it’s the way it should’ve come from Honda with the streamlined wiring and shit.

OEM Plus – boom

    That is awesome. One of my 450 goals is to strip out all the unnecessary wiring and junk once it’s roadworthy.

  2. Todd says:

    Don’t mess with the trannies man, gross.

  3. Richard says:

    Lets see it with 500t headers and 450 mufflers or a 500t tank..

  4. aaron says:

    if you put on a 500t tank ill buy the 45o tank.

    careful with the jb on the aluminum, sometimes it doesn’t play nice. if it ever fails, Try using a freeze plug like this – http://www.chopcult.com/forum/showthread.php?t=9079

    I’m not putting a 500t tank on it. Keeping with the 450 stuff.

    yea man… i know this was a super ghetto approach, but i couldn’t find a legit plug. Wish I had known about that. Fuck it… i think what I did with the washer will hold. Really, the JB weld is just holding the washer against the case. It’s not filling material or anything.

    This was a rad project. Glad we did all the little streamlining things to it which gives it a cleaner look. The 450 has always been a good looking bike and now it’s even better!

  8. Adam says:

    The only thing it needs is the cb175 stock tail light that Ricky has for you.

  9. admin says:

    yea, def putting that tail-light on.
    maybe i’ll come up friday night to put it on.

  10. Nice work! Looks great.

  11. Mike says:

    the cb475 rips. cool name.

  12. Trace says:

    Bike looks great! Could you do a write up on simplifying the wiring? I’ve always wanted to do it but it seems like such a daunting task.

    Where did you buy that seat?
