The solution for four-stroke 250s?

with one of these your bike might make some power!

or maybe not..

I think by the questions they're fielding and the (thus far resonable) tone of the replies they know they've got a lemon.
The concept is sound but without some technical info why bother.

Might be a hoot on a grasskart engine. Doesn't matter if it flys to bits and roots the engine then does it?

quite serioisly, there is not way a piddly electric motor could generate airflow anywhere near to, let alone exceed what the bike would induce through the air box naturally. all that will do is kill your power as it will be a massive block on any airflow into the bike. it may be use as a hair dryer mounted on your handle bars however?

now if you actually turbocharged it, then you might get some cool power!

the problem with that is that most bikes are producing as much heat as their cooling system will allow for allready- add a turbo to the mix and you have more problems.... not to mention turbos like dirt particles / water going through them even less than a standard piston engine

I always wanted to try something like this :innocent:
just have it hooked up with a VSD and linked to the RPMs or throttle position, simple as bro :Punk:

if it was a bit better quality lookin I'd try it!

This could well a good alternative to using hi RPMs to make power on 250fs

Why not just buy a 250 T and save the expense ?

You're talking about adding more moving parts to ...already too many moving parts ,

So many moving parts and, so little power gain...you must have more money than I to waste on polishing turds .....go the 2 Strokes :bye:

quite serioisly, there is not way a piddly electric motor could generate airflow anywhere near to, Umm, it's not a piddly electric motor.

14 Volts x 10-to-14 Amps = 140-to-196 Watts.

So another problem is how many 250 4T's have a spare 196W out of the generator??

[CRF119]

Some things really are made to just fill landfills lmao

[cheese]

Nice idea, but you need to vary the air pressure depending on demand. So unless its got some pressure release valve of a variable speed controller that adjusts itself to revs, its ass.

My vote is its ass.

Think about how much air flows through a 1800W vacuum cleaner. Take one tenth of that and compare it to the air requirements of your 250..

I think very much insufficient..

[warewolf]

I think very much insufficient..You could very well be right.

So it consumes more electrical power than the generator can supply, can't flow enough air, doesn't vary with the load, and if it did it would overload the cooling system.

Any more negatives?! :D

yup mounting it and i wonder how well it will go after you go flying through a large puddle let alone sand. Besides where in the hell are you going to find the room to fit it????

[barty5]

I wonder if he is related to this guy????http://www.youtube.com/watch?v=qX0lnPZX6HU

[secondfield]

Nah' hes actually this guy ...

In short a similar effect to the "power bands" you get sometimes get as an optional extra for your smoker?

[warewolf]

and... luxury exhaust! :yes:
