When someone gets 100hp out of one & they weight less than 130kg.........., check out the Tigcraft specs, thats the bike to beat.

Think you might have quoted the wrong post there mate.

One of the things I was looking at for new projects is an engine made by a guy in England. It's a 1 litre, 100hp single cylinder. Hmmmm ....

lawks. got a link to that?

I originally asked him about the Husaberg engines he builds and got chatting. Turns out he's been spending lots of time on designing and building the 1 litre 100hp single for customers to purchase. It's about £6k for the engine, electricals, electronic gearbox, data logging, fuel injection etc and going into production in 2 months. Only thing missing is the frame, wheels and brakes.

He hasn't updated his website for about a year but you can email him about the engine or whatever else.

Awesome to see Shane!!

Very cool. Keen to hear how the rebuild/modifications go. Especially replacing the piston and rod with a balance weight... Has that been done successfully before?
Good luck with it!

Cool, i wonder if the piston stays still & the rest of the bike goes up & down instead ? :-)

Yes, it has. Although that engine is currently in bits cos the crank touched the crank sensor making it run on 2 cylinders. However, it made 10 more horsepower than the short stroke 4 cylinder that was originally in the bike.

The short stroke engine didn't really work because it was insanely over square and had to rev to about 20,000rpm. But the valve gear etc would only handle an absolute maximum of about 17,000rpm.

Put it in a light weight Tig Craft frame and the answer would be yes!!

I have a VFR400 NC30 rolling chassis. This is a BAD IDEA

VERY bad. I believe the NC30 chassis is spaghetti without the engine bracing it. Sticking something that will probably twist tree stumps out of the ground into it is likely to break it in half before you get to the end of the driveway.

thanks for the reality check. but still! it would be like my old SRX6 x a million.

Wow! Did it vibrate much? How much more hp did it make over leaving the piston and rod in?

[Mental Trousers]

He's never tried it like that

Id pay money to watch somebody kick start it.

Oh yeah! stick that in a 675 frame and you'd be laughing

That is exactly what I was thinking.

Until I found out about that engine I was keen on putting a Husaberg 650 into a rare-as-rocking-horse-shit-250GP frame. But they're impossible to find and the 1 litre engine would break one of those I reckon. They're strong frames but they weren't built for the amount of torque that thing would be throwing around.
