ghostrider13 0 Posted July 7, 2012 yet again my lad pushes his bike home only he's done it proper this time. Now i have to be rebuild the engine cant really blame him tho looks like the oil pump packed up and siezed it. Not too bad to do it's only about £80 for a new top end thats the beauty of a two stroke cheap to fix but this is the third engine in 2 bikes blew the first one up twice. What do you guys and gals think about throwing the oil pump away and pe-mixing? ive things for and against but would welcome your thoughts just to let you know his bike is a gilera dna 50cc Share this post Link to post Share on other sites

Macie_UK 0 Posted July 7, 2012 Was quite common with TZRs to forget the oil injection pump and go down the premix route. I actually bothered to fit a new pump because I CBA with the faffing around and I'd more than likely forget about the little bottle of 2 stroke oil under the seat until just after that 'clutch in sharpish' moment after a lock up Share this post Link to post Share on other sites

Chadatious 0 Posted July 7, 2012 Mate pre mixes and bike plays up more he's going back to the pump I think. On a mito 125 Share this post Link to post Share on other sites
Tony nitrous 0 Posted July 8, 2012 Unless its a design fault on the bike, a pumpshould be better than someone trying to carrya bottle of oil and judging the mix at the pump.Mate in a shop said it was quite common tosee "dry" pumps where kids had ran out, seized the motor, THEN topped up the tank.. How old is he ?Move him up to a 4-stroke thats a bit bigger ? Share this post Link to post Share on other sites
