Bike engines, just pondering out loud.

[CR500Dom]

You only have to see how well Topi`s XE motored Kadett went at RRS to return to the age old Adage:

Keep it simple

Tigs - this is the bike engine that you really need

essentially a pair of Busa motors made into a V8........

Yeah dom it's a good way to go and it does the job but it's becoming common now - even with older vauxhall's. Just pondering about something at least a bit different.

I should revive this thread for ideas as well,
owner of:

'71 Honda Z360,

like: www.flickr.com/photos/hondazcar/474613010

Smaller engined (J spec.) relative of Honda's Z600.
Really did share much of its engine design with the Honda CB360.
Air-cooled, roller-bearing 'built-up' chankshaft, gearbox behind/incorporated-in rear of crankcase & getting its power via chain from the crankshaft. Giving 35hp@9000rpm
Though obviously there were many changes to incorporate differential for FWD packaging but weighing in @ 510kg useable at the time.

Obviously 600 engine possible though like the cars they're not exactly common.

'65 Honda S600.

Really didn't share anything with bike ancestry beyond inspiration,
water-cooled 606cc DOHC Alloy 4cyl. with roller bearing built-up crank.
Standard RWD car drivetrain layout but for rear trailing arms containing drive-chains to give independant rear suspension & shorter rear packaging.
Engines in a million bits many of which are unhealthy/ missing hard to get !
S800 version of engine not exacly common / cheap either.
59 HP @ 9000rpm , bit overweight though at 720kg

Ideas?

my 2p.

under 500 kg

mid mounted and chain driven

any other way of using a bike engine is a waste of time ,prop and diff drive soaks up power and limits gearing ,excess weight really takes the edge off but stick to those two rules and you will have a fun toy that is pretty sharp up to 80mph

There are some very light car engines about now, Mondeo Duratec is one example.

@ tigran what is it being put into? i'd never put it into anything over 600kg and even at that it would have to be
a turbo bike engine. 600kg may be attainable with the old iron engine & gearbox & interior striped out.
Skip the busa engine and just get an old gsxr1100 and slap on the turbo. end up cheaper that way with a little more power.

Bike engines belong in bikes

For a car

Ain't no replacement for displacement

A stripped out to the max viva. so would still be in the mid 700's weight wise. Think i will settle for a zingy dohc 4pot instead. Wonder how much S2000 engines go for.

How bout a Vtec out of a Civic VTI/Crx. 130-170 bhp and cheap but not sure about converting to RWD

[TerraRoot]

situne did an escort with a turbo cbr9, it's not very fast. but it's about the same as a viva

some vids to slow how much weight is important.

qwerty b+d series honda engines run backwards, hence no rwd box's available
