hi all,I am new to this forum & a newbie to scooters.
I recently bought a standard x-reg malaguti f15 firefox. All was running fine (except twice about a month apart it lost power then came back after I gave it a rev then let it idle a mo whilst coasting down the road) until recently...
Changed the rollers from 5.5g to 3.5g, removed the spacer between the vario halves and it was zipping along! The standard exhaust then snapped so I put a friends aerox pipe on with TT silencer.
All was fine until last monday I was riding along at about 40mph when the bike started to bog and would drive at max 7 mph. I pushed it home then took it to my local garage where they diagnosed a dirty carb, cleaned it and I left.
The bike still lacked any grunt with a max speed of 41 downhill. Took the bike back where the garage again adjusted the carb. It seemed better but still wasn't right.
The garage then diagnosed worn rings with a compression reading of 76 saying it should be 100 - 110.
I was desperate to sort this out so ended up forking out for a 70cc kit after advice that the original head & cylinder would be knackered & the 70 kit would work with a little tweak of the carb. no up jetting required.
Put the 70 kit on it, fired it up & no matter what I do with the carb the most I can get is a sluggish acceleration on a slight downhill gradient up to a max of 43mph. uphill its doing 17 - 22mph.
Have been advised I should put a 21mm carb, jet & k&n filter on. However, have also been told it should be running fine with the original carb.
With no load the bike revs straight up to 10000rpm but with any load it struggles.
Have been told today that I should now replace the CDI unit then if still the same the magneto flywheel. I just don't know what to do with this anymore. Do I spend 200 on the CDI & magneto then another 130 on carb, jet & filter?
Thanks for any help with this.
