[BETA EVO 300T Factory (or not?)]

an easy way to find out about this bike is to go to the   " betamotor "    website   go to the parts finder and type in the VIN       no more guessing

[1993 Gara: do they always do that...?]

The stock float needle was a metal to metal type.  There is a viton rubber one available that works much better.  There are also some set up tips on this forum.

If the issue is just when the bike is cold, you   could go to an oil with a lower first number possibly a    5W50   or if where you live it never gets very hot perhaps a 5w40

[2001 txt 280]

There are some videos on the     " trials parts usa "    you tube channel covering this.

If  tony27 is correct, I think I would make sure that my gearbox breather hose is not blocked. This may save some work.

 

[Hole above gear lever]

If you have trouble finding a p/n it is the same fitting as a dell orto carb float bowl vent

[Trs not running right]

Sometimes people lose the needle jet when cleaning the carb. Some bikes run poor to fair in this condition but will not run great.If you take the airbox off at the carb, there should be a brass coloured bit sticking up from the bottom of the carb. That part is the needle jet.  Good luck.

[Spares etc]

If you are older reading glasses, also. a spark plug and suitable spanner

[1996 gas gas 270 idle issues]

Sometime the floats in the dell'orto carb   DO NOT float anymore       good luck

The first generation Pampera (released approx 1996)   had a smaller radiator than the later models. These first Pamperas also had the  "trials gearbox"   , later models had some gears with different ratios.

Does the " Aspen fuel "   make any difference how the bike runs ?
