540cc Honda 360 Engine

[teazer]

As to exhaust holes, I did an inadvertent load test in the form of
knocking frame and engine off the bench, it rotated 320* and landed on
alt cover, smashing cover , stator and small cover. No damage to exhaust
holes or struts however. Not even a paint scratch on frame. New covers
are ready to be painted and installed shortly.

That didn't prove a whole lot except that the motor is located by the rear mounts primarily. The forces in a running b ike are smaller magnitude but greater frequency. I'm not making any assertions as to what will or will not fail. Just commenting on the "testing" methodology and extrapolations.

Heim joints should be adequate for the suspension forces. Not sure which other bikes used them in that situation though.

Front rim is wider than my 100+HP bike, so I would hate to ride that too hard in the rain I suspect that the lack of weight/pressure over a large surface area might be sub optimal in wet conditions particularly.

wich type and size of tyres did you use?

 

[crazypj]

Almost all sport bikes use a 120/70~80 front tyre on 3"~ 3.5" rims
Trend over last few years has been to go slightly narrower on rim widths and use lower profile tyres, rear rims are now generally in the 5" range with 180 tyres

Teaser, I have never made the connection you just explained regarding front tire size. It clearly makes sense and I will continue to absorb. Thanks now I can tell my GF bigger is NOT always better.

how about an update on this motor and bike?

The comment about the "test" was made in jest! I should have used one of these:

Stainless seat pan is finished.

Here's the seat pan after much work. I think it came out good, almost straight and fits good. Tab on front slips under bar on frame to hold it down, one fastener on the rear somewhere to hold in place.

love the seat mate and i just saw the adjustable shock mounts great idea looking like a great bike

Pictures of the muffler so far.

 

[crazypj]

Nice machining and design
Surprised you didn't kick it up a bit higher though particularly a there is room for a longer pipe/silencer combination.
Stock 360 'likes' a pipe that ends around rear axle, with a lower red-line I would have though a longer system would have been automatic choice?

 

[Flugtechnik]

That's interesting. How do you seal the header muffler joint?

I see a potential future bikeexif/pipburn bike, but for the love of god does it run!? I can't wait to see this in action!

Hey guys, the 540 was put aside while another project was finished, but now we're back on it. And it is a runner! The engine was run on the bench and sounds great! A video will be made soon and posted. Stay tuned.

To answer a couple questions, the pipes run inside the muff housing and seal with a tight fit at the front cover. I'll post some detailed pics later of the guts.

Awesome!

Bikeporn. But, like more members a bit scared about the exhaust mounting..

A few pictures and update:
When I started the 540, I couldn't find the cam seal so had to get a
new one now have it in and pts back in. Also ordered two new
Ford condensers, as bare wires on the old ones. Used perf. stainless
for mounting bracket and bat. box, which is on the swing arm. As soon
as the relays and misc. parts come in, I will wire it up and it should
run again. Springs for pipes and regulator for charging coming also. I found a
way to test the HI-4 Harley ign, You were right, was bad on rear
plug. I also found a way to make it work on a Honda twin. I might try
to find a good one to convert the 540. I built an oil filter mount and
have that bolted on. Still working on shift and brake pedals and
linkage.

Oil filter, struts and cut down cover:

Awesome look forward to seeing where this goes!

Here's a quick update on the bike. I received these pics from my dad a while back, but haven't had a chance to post them until now. He stitched up a seat cover, changed the pipes to now exit under the engine, I think he will still use the same muffler, looks like the carbs are mounted on some long runner intake manifolds, and wiring and bars are coming together.

That's a whole can of awsome sauce!
