HPI baja 5b Engine upgrade/maintains!!
 

hi,
I have an Hpi Baja SS 26cc,I have just upgraded to a 29cc engine/pistons,can I run the engine on full throttle or should I wait for a couple of tanks to finish Before hitting full throttle also should my petrol to oil ratio be the same or should I use more petrol ratio then the standard(25:1part oil).I also wanna know what makes the pistons burn out i mean whats the best way to have your piston live a long life in a baja.any info on the baja 5b about maintains would be appreciated.

Thanks..

hi bob , heres what i would do . use standard fuel . wind both mixture screws all the way in (gently) . then wind the low out 1.5 turns and the hi out 1.75 turns . use standard start procedure and it should run fine but smoky . I would do some 5 minute runs - letting it cool off for 10 minutes in-between - at no more than half throttle . you won't burn a piston if you can see some smoke from the exhaust at all speeds . when there is no visible smoke , the engine may be too lean .
