SPEEDFIGHT Prost LC 50/70cc

[Tricky Mickey]

Hi Guy’s
Thanks’ for the excellent advice, spent sometime reading the tips on tuning before I started on my Prost LC 50
Just need to do some tweaks’ and I will take it for a run tomorrow
Fitted a dellorto carb off a speed fight 100 cc it has a 82 main jet
May need to change it after testing ? Do you think its OK
Fitted a Ginnelli exhaust
Fitted a Malossi 70 cc big bore kit

Thinking of fitting a TNT racing variator kit what do you think ?
I did have some front end wheel wobble have changed the shocker but its still
doing it the only thing I can think of it may be the bushes in the linkage
Can you get a replacement kit?


What do you think ?
Thanks’ for any help 9||6

I really do need help
The engine runs sweet and revs clean !

But try to set off and it just crawls along don’t think its hit its rev band yet a bit like setting off in top gear !

Cleaned and checked the disk and calliper not the brake sticking on
Put the old drive belt back on still the same

Moved the needle on the carburettor from top to bottom no change

I do not know what the weights are in the variator possibly 6.5g, but I am starting to think they are to light and need to put 8g in from what I can gather it would improve bottom end

Can You Help Me Out Please
