water/liqued cooling

[sean brady scooters]

surely this is the way forward.............
and is really what modern high perormance lambos are desperatly in need of............
most probs that folk have trouble with is more than likely down to overheating..........poor cooling...............
what with ever increasing ,higher revving ,bigger bore CC kits.........surely the max cooling effect from a fan /air inducted system has been long ago found to be inadequate...........
its a shame really that the range of new RB kits ....were not offered and made water cooled...................
of course ,if they were .........it would be far more expensive................
but then ,.........they would be far more superior.........

water/liqued cooling was taken on by racers 20 years ago...........in order to maintain high performance/reliably............

most modern reasonably high performance two strokes are always now liquid cooled........................and for very good reasons..........
yet most tuned lambos.........200 to 250 cc..........are still forced air cooled...........and hence suffer the consequences ............

[sean brady scooters]

its just my oppinion of course..............but.....
modern day tuning/kits etc have far surpassed the max output from any forced air cooling
that a std lambo can provide.............

[byron]

is it enough to cool just the head [like the kit MB did/still do?] ?
or is a full jacket around the barrel needed ?
then there's where to fit the rad, and getting some 12v DC for the pump, and fan..?
I do like the idea, anything to help keeping it cool

[sean brady scooters]

the water pump.......could be .....like so many twist and go ,s.........driven mechanically from the flywheel.............
which would have course be lightened a lot ..........not needing any fins.............
a liqued cooled head is good ,and maybe an improvement but then not as good as a whole LC barrel ................

at best ,its just a half attempted effort .............

i was hoping that mb or af might introduce such a kit barrel piston head pump rad and all fittings to put the lambretta on par with the jap bikes.
sean i remember lads experimenting with water cooling 35 years ago brazing a jacket on a cast barrel,which is a lot harder than welding the jacket on an alloy one,
lots of lads like to try and keep the scooter looking as origional as possible and maybe will not like the idea of the rad stuck infront of the legsheild,maybe the rad could be fitted underneath the footboards with a duct forcing cool air through it.
lets here your comments here?

readspeed do some nice stuff its not on there website
i agre about the fan being at its limit but fan/blade technologey has moved on since the 50,s vespas pass more air quicker than a lammy as well cowling size/fit/cut outs as well could lead to incorrect cooling(im aware MB are working on this) ,forced air cooling is still used in the food/ drug industry and on belt and roller conveyers around pumps and motors
its a shame dealers are only half arsed about going fast if someone says to me i wanna make this scoot faster i say well start with the brakes/tyres/lights/suspension/rims then when you have spend £600-£800 on those then maybe we can start......then they go of and buy a seizespeed barrel from epay and a carb from a bike and prob a £100 stainless expansion 2 months later there back err mister can you fix my scooter

Thats what Frank Sanderson has been doing with the Series 5 Auto Lambys for the past 3-4 years or so as I have mine converted in his way and it (touch wood) works well and still retains the looks of the Lambretta without having a Rad stuck on the font.

[sydduckett]

Mate has his TS water cooled with a rad under the flooboards, said he usually runs at about 65 but was on the rally in london last year, not able to get going due to traffic and it went up to 110. said he was shi**ing himself. Says they are great when moving but not so clever when in traffic.

Thought i would add that useless bit of advice....

It would be a very limited market I think. Too many people want their scooters to go fast while looking completely standard.

Ive being thinking about some sort of ducting system starting from the bottom of the legshields running down and force feeding cold air straight onto the head through the cowling...but its still at the thinking stage and like Ian says to many want to keep the factory look and who can blame them!...I would just like to be able to go quick for long periods without worrying if its going to lock up miles from home...One Potential problem crossing my mind would be IF this set up did work and kept the barrel at low temps while riding would the timings or carb settings need altering at all?...Sean
