Heres my latest bike , built it over the weekend ,just finishing a few things ironing out a few bugs , The RockSolidEngines 200Watt two stroker is very low powered but it keeps me out of trouble on our Aussie roads , I have played with the motor a bit and its easy enough to get more power out of it .
But its a nice motor, all the bolts/studs/nuts are replaced by RSEngines and it starts easy and the bike is fun to ride .

but ive blown the rear rim an bent the shaft ..
bloody redlight runners

any chance of a pic of compliance plate so i can make my own fake copy using my own build number so i can keep mr plod off my back ????
:whistle:
 
Wild looking bike, Simon.
Did you build those front forks?

I've been thinking of buying one of Tony's 200W engines.
What's different from a normal 48cc to reduce power?
Having ridden it, do you think that it really only produces 200W?
You say it's tweakable - is there anything to stop it being brought back up to full power, (or higher)?
I'm thinking 66cc top-end.
 
Hey Steve , the forks are just good quality bent springers ,some are better than others but these are definitely a better example , the 200Watter surprised me , actually I didnt know what to expect as I have never ridden anything so low in power ,but it helps you along , as far as modifying for power ,theres a restrictor in the carb and the compression is significantly lower , all easy to change and you have normal 49cc power levels . it really is a case of trying to have a legal bike tho , if the cops can see you pedaling all is as it should be in their eyes .
I seem to be able to pedal just on top of the bikes bottom end power , the motor with the restrictor and low comp will not rev , and this is how the 200w level is acheived , cos as we all know a 2 smoker has to rev to make power ,all good clean legal fun .
 
Sounds like there's a lot of pedalling involved. I can't do too much of that. I know what I'll do if I buy one.
Incidentally, is the plate on the magneto cover the only identification, or does it match to a serial number on the crankcase?

I never need to pedal on my 200W electric. IC engines need to be rated differently, since their power will only hit 200W at a particular rpm. An electric develops good torque right through the rev range, making the 200W more usable. Maybe 500W for IC engines would be more appropriate.
 
Well its very easy pedaling once your moving , I doubt its going to stay at 200w ,this bike that is , I reckon around 1000w is realistic , 1 Kilowatt , as long as Im not straining in the headwinds and hills Im happy with it , the build number on the plate is the same as the crankcase #
 
the build number on the plate is the same as the crankcase #

That's good to know - keeps people honest.
Otherwise I was going to suggest that you use tamper-proof or similar screws to protect that $450 magneto cover. (Might still be a good idea, it wouldn't be too hard to hide or remove the old number from the crankcase and stamp another.)
Those maggy covers are worth protecting.

I agree, 1000W is probably more realistic. My 200W electric wasn't too far behind my 66cc HT, (at 1700W), before I tuned, modded and added the shift-kit to the 2-stroke.
Out of the box, the HT did 33kph. The electric does 25kph or 30kph with a slight tail-wind. From about 10mph, the electric actually beat the 2-stroke for 10-20 yards, (metres), in acceleration.
(Not any more, with RSE hi-comp head, good tuning and a shift-kit.)
