hi, am looking to do a 172 con on my speedfight 100cc,,, i wont a runner L/C engine, has any one done this and is there any pic's i also have issues with the cooling and mounting the engine will the speedfight 50cc rad be efficient enough to cope with the hi temp if i fit a external water pump (12.5L/min) i also want to know the best way to mount one,,, i dont wont the engine to point up to 11'clock as iv have seen some pic's,,, i wont the engine to be horizontal,, can any one help,,,, thanks duzzer :grin:
lol, i carnt be botherd with an other bike,, just wont to tune the one i'v got,, seriously munnys not a problem but the power out put from the 100cc speedfight engine is,, :rotfl:
sell it buy a runner not as simple as just bolting engine in you will have to change the loom put a different rad the munting sysytem for the engine is copletly different to a gilera piaggio mount then you also need to move the rear shock top mount further back not a quick job and deffinatly not an easy job pretty pointless tbh
change the loom different rad engine mount rear shock top mount further back thanks i will have to look into this,,
i really wouldnt go wc ona speedfight tbh if you REALLY wanna do this then put a ac engine in there there cheaper to buy and will be a whole lot less work?
if you really are goin to go through with it stage six do a engine mount conversion kit its for a 50 piaggio engine so will have to grind it down a bit each side but would be easiest bet
you can make your own engine mount froma a peugeot subframe and a gilera subframe once welded together engine bolts straight in get a mount further back for the shock and engine in if you go a/c i can supply you a full wiring diagram to wire up the harness im on doing my second speedfight 172 atm with a typhoon lump
arr nice one, can you pm me some pic's of the subframe, am trying to pitcher it in my head,, do you meen weld the gilera runner subframe under the speedfight subframe am going L/C,, thers an engine (125) not far from me that am buying in 2-3 weeks thanks every one
this is what i meen by 11'clock,, i dont wont the engine to sit like this as it look pants,, i wont the engine to be horizontal,, am starting to think (and it hurts) that if am on the same wave lenth as speedy 172,, wont welding the runner subframe under the speedfight subframe lower the front of the 125 engine down to be more horizontal and by moveing the the rear shock mount back/up the frame lift up the back of the engine?
basically mate you want the part of the subframe off a runner that the engine bolt into, grind the end off it so it is the same size both sides, get some washers to space it out so its centralised, then bolt the subframes together, get a piece of thick metal plate and go to a welders get the subframes welded together with the steel sheet on the side for support you would end up with something like this and for the new shock mount you want a thick L piece of plate i drilled through it and my frame used 2 industrial bolts to bolt it on then took the bike to the welders and had it all welded up
ye, big fat boidge... and the engine wont go higher at the back (where it should be) as it fouls the frame.. only way is to remanufactor the mount further back and lower so the engine sits flat, this in turn lifts the seat to a silly hight.. other way is box out the frame, lots fo work.. i wanna know if any of the speedy's you have done have actually been registerd/sva tested as any conversion from a moped to a motorcycle requires diff classification on the vehicle. meaning it needs more than just sending off the logbook as "motorcycle" and moting it.. more to the point insuring it will be near impossible/well expensive as they dont make a 125 speedfight. go for it if you like.. you will spend another bikes value on the thing.. meaning it will end up taking the cost of 2 bikes to make a bike thats not even as good as the one you ripped to bits to build. makes NO sence. speedfights suck, they dont handle, electrics are poo.. why would you want to put a big engine in a bike that cant handle the speeds? if you weld the mount like that your gonna die.. its NOT safe.. theres not enough area to weld to to overcome the sheer force of high speed cornering/speed bumps.. i dont care if one or two have lasted so far.. come see me after 5 years of speedbumps. its NOT safe. do a distruction test on the thing and you will find that out (you know, the tests manufactors have to do on there engine mounts.. the tests these aftermarket kits are never put through.
the 1 i have now is down on the log book as a speedfight 125 minor and insurance through ebike with all mods declared 240 a year the bike has been inspected by a dvla representative which was not needed but i allowed :good:
and there not like the runner 50-125 conversions, where the peugeot subframe sits there is a really big thick rubber bush that takes force/shock away so its not as if thesubframe is welded into the frame
well i got a converision i LOVE IT,, argee with minor on the insurance thing tho,had a few calls going over the fact there is no aerox 125 blah blah got it sorted in the end tho but it wasnt easy or cheap!
your still describing a way of welding to this... wich means a little peice of metal is being pry'd against by the enigne ACROSS the weld face... its a no no in ny chassis desighn and is unsafe. the weld should be across the top and bottom of the mount, not on the "cheek" of the mount, danger danger. 240 with all mods declaired? what, on your mums policy? my friend (24) try'd to insure a 172 typhoon (125 frame) couldent get it below 700 quid.. fact is his r6 cost's him less to insure so im a little skeptical about that tbh.. maybe they have treated it as a speedy with a 125 bore kit rather than paying attention to the fact you have alterd the wheelbase meaning its due for an sva test (single vehicle aproval) you slkipped through the net, wich alot of conversions do, doesent make them any bit safer/more legal. christ im supprised any mot centre passed it wiht the engine at that angle.. so you somhow insured a 172 speedfight, for 240 quid? love to see that cover note
Whatever you do dont buy the subframe off speedy172/steve waters as he still owes it me from 7months ago nearly
mate dnt do it just but i runner our a typhoon 125 if u fuck up it could kill u u spend more money doing it
