Hi all, I've only been riding bikes about 2 months, started by sharing my friends Montesa Cota 315R(97) and have recently bought myself a Gas Gas JTX 270(97), so far have managed to get out for 1 days worth of riding which was really good and to be honest I do prefer my my bike as I'm 6'2" and the handle bars seem to be a little further away and unlike the Montesa I don't feel like I'm going to go over the handle bars everytime I brake hard.
The biggest problem I'm having is trying to get good info on the type of oil I should use in the gearbox/transmission, someone where I went trials biking had the 250cc version of my bike and they said to use 10w 40 but on Gas Gas website it says "Always 5W30 (Not 10W40), 350cc for the Pro, 650cc for other models, normal motor oil (Castrol/Penzoil etc). It is not recommended to use synthetic oil." The nearest I've found is 5w 30 semi synthetic, but on the castrol website it says to use 800cc of MTX Part Synthetic.
I'm also unable to find a manual for my bike online.
Someone please help.
Many thanks,
Andy
