Scott_87 Posted October 18, 2009 Report Posted October 18, 2009 So recently bought and had installed a recon 5k motor, had all my old stuff of the 4k put on there. First question is while wearing the motor in like a grandpa ofcourse I've been noticing when I slighty put my foot down while not under load and in low revs I get a loud almost tapping sound? Second question is it worth putting a 5k started motor in or is the 4k one plenty enough? Think my current one is struggling so wanting to replace shortly. Thank you in advance Scott Quote
Evan G Posted October 18, 2009 Report Posted October 18, 2009 regarding the starter motor question, is it a bog stock 5k? or mild engine? check your earth wires and upgrade the wire that goes between the battery and starter motor to a thicker one Quote
philbey Posted October 18, 2009 Report Posted October 18, 2009 (edited) Check your leads etc to the battery. I'm running high compression 5K and the stock ones do the trick fine. Mind you the 5K reduction starters are highly recommended but don't come cheap. Edited October 18, 2009 by philbey Quote
Scott_87 Posted October 19, 2009 Author Report Posted October 19, 2009 Sorry got stock 5k with 32/36 weber apart from that and extractors completely standard. I'm thinking the sound I'm getting is pinging how do I check? Thinking I will just replace the starter motor and while there check the wiring Quote

I'm thinking the sound I'm getting is pinging how do I check? Thinking I will just replace the starter motor and while there check the wiring The "tapping" sound is pinging/detonation... It means the timing of the distributor is too far advanced and it is sparking BEFORE it needs to, making you lose a LOT of torque. If you don't have a timing light, just keep retarding it (less advance) and drive it up hills to test if it is still pinging. Once it stops sounding like you have marbles in your motor you should be pretty right; but it does help to get it properly timed. Edited October 19, 2009 by seabiscuit Quote
Taz_Rx Posted October 19, 2009 Report Posted October 19, 2009 What type of fuel you running? If using ULP then try some PULP and see if it stops pinging. Quote
Scott_87 Posted October 20, 2009 Author Report Posted October 20, 2009 sweet will do thanks guys, yeah i did notice and thought it was pinging once i put in normal ULP instead or the usual PULP. Quote
