Honda Odyssey 350
 

intro: I have a Honda bugy odyssey 350. I have some problem on the clutch (as it does not couple on low RPM but when rather high) I ordered a new clutch. I also bored the cylinder and installed a new piston and i have the following questions
1) what oil type do you put in the transmission and what in the engine
2) the shifting of gears is not smooth as it grinds or the gears a little bit. what could be the reason? high idle? but transmission? or something to do with driven belt system?
