Good Top-End Silencer For Ty250?

[dannyboi]

Hi, My ty250 has plenty of power, but only at the bottom end of the gears, as soon as i hit half revs and upwards it just doesn't gain any power at-all, which means i resort to staying in the bottom end of the gears.

At first i thought that this was obviously how the trial bike was designed, not the top end aggressive nature like a motocross bikes.

But my friend has one also, and pulls through the gears no problem. I have a ty175 also and i sometimes think that it is definitely faster than my 250, no power issues at-all.

I have changed the gearbox oil, put in a new spark plug, cleaned and checked my air filter and cleaned out my front exhaust but to no avail.

I dont want to start fiddling in-depth with the mechanics, as i know nothing about them, and i do not want to start blowing all my money on it.

Anyone know or think that getting an aftermarket silencer may change the performance to gain top-end power? and if so which one? cheers

Also would anybody be able to confirm the year of my bike? its serial number reads 3BA-000378

Looking on the tytrials site 3BA is 88

Have you tried your friends silencer on your bike to see if that improved the problem?

Simply take the silencer off for a test will give you an idea.

Often the middle box becomes clogged and needs a good clean out.

If not the ignition timing may be very retarded.
