MXFredericks: Thanks man helped a lot, building a 1994 CR125R

MarchJude_ -: My 94 fourtrax 300 runs perfect and starts without any flaws... but after about 20-30 min of riding the bike will start lose power and then it Almost feels like it's out of gas ...after that it stalls and I have to give it like 2min then start it again and it just repeats

ValueFor MyMoney Singh: is there a rpm limit wire in cdi

Trevor Meersman: how come my cdi is a four plug

gratefulTed: and a wide range of adjustment eg if bike kicks back when starting you can retard the ignition slightly.

rick benavides: I Have a 2004 Honda Shadow 750 Aero, my problem is I have no Power at all, I replaced the Battery and still has no power.No Lights ,horn, turn signals NOTHING! I checked the fuses and all appear to be ok, I was not able to check the main fuse (if Any) because I have no clue where to locate it, any suggestions to what may be causing this NO power problem?...Help Please!

happyONE LIKE: sir did you have a vid. that showing how to know if the rectifier is damage or not if the rectifier was damage how to repair it thanks im from the phil...

Kevin Stearns: im asking you cause you have over 800.000 hits 87 kx 250 cant find a cdi its a one year only go fukin figure. i bought an 89 kx 125 with the same color wires. will this work? if not any ideas what will. thanks.

R1 Menace: is cdi and ecu box the same thing? i found the ecu box on the oem parts list but not the cdi. i think its the same piece. my 4 stroke is only firing on two plugs. the coils where replaced and same issue. i switched the coils to see if one of them was bad but it was the location of the left spot that was not getting current through he coil. i assume its pre coil for the issue. the next item before the coil is the ecu box. someone correct me if im wrong. i dont want to fork out another bill on a waste of a part if its not the issue.
