Speedy slight problem

Hii i have a 53 speedy 2 L/C and everything was fine with it getting 52 clock speed , but suddenly today when i went out on it i could only get 45 when i have it full throttle or it would sometimes get to 52 if i released the throttle and then opened it fully again but would take way way longer then usual .. i though it could have been the zaust so ive re-packed the end can and cleaned out the main pipe with costic soda but still i have the same problem .. anyone no what it could be ?

rollers ?

 

french nah i cant talk. like said check the rollers mine went down quiet abit when i had flatspots.

 

I only fitted my malossi multi-variator about 300 kms ago though with brand new rollers in "/

Does your carb have a diaphram in it? you could have a small hole in it or a little gap.

 

maybe spark plug needs replacing....foam element in the airbox needs cleaning...

 

Rollers = fine
Cleaned air filer and compartment out with petrol .
Jet = fine
Cleaned out carb bowl
Put new spark plug in

Still not fixed the problem

 

sounds like general wear and tear to the transmission to me

stick a new belt in and ee what its saying...

 

Reeto iyl try one of them [Y]
Do you think it could be out MAJOR though ?

John

 

Tryed a new belt and no difference
Do you think it could be my engine ?
Like it needs de-cokeing / new piston rings putting it ?

unk:

 

check tires, badly pressured tires can easily kill 5mph off top speed.

one thing you may need to remember is that you should never clean an air filter with petrol, use warm water and and a detergant of sum sort then apply air filter oil to it.

 

i use warm water and washing up liquid

my runner is an 02 model and still has the original sponge air filter element it left
the factory with.... i just wash it a couple of times a year
