So i bought a 1992 rm125 about 1 week ago and it ran fine! i got it home and rode it for about 3 days, then after i let it cool down for about 20 minuets it would not start! I checked for spark, and for some reason, there was no spark. I bought a new ngk plug, and still nothing! I went through all the usual stuff, and still nothing! I bought a new stater, put it on, and now it will bump start, but not start using the kick starter. ( the kick starter is 100% good ) I think it may be the ignition coil, but i am not 100% sure. Any ideas?

Hi guys, praying someone can enlighten me Lol i have a 1993 suzuki rm80 2 stroke and i want to swap out the original forks for the upside down forks off a newer shape rm85, does anyone know if the headstock is the same size on the newer shapes ie.2015? Or if there is another set of upside down forks that will fit on? Im aware the fork yolkes will have to be changed with it just praying someone had the knowledge i dont! Thanks guys #rm80#Suzuki#forks

My son's 1983 RM80 has been giving me stress the last few days . it was performing great as it should then out of no where it has no high rpm power , will not hit power band . It starts great , it idles fine , part throttle performance is also good , it will perform as it should until it wants to start revving out , then it just lays down . The low end power feels about right , but will not open up . It acts just like a 4 barrel carb that has the secondaries locked shut ( for us old school guys !! ) Actions Taken : (In no specific order ) 1. Removed carb , disassembled and cleaned out thoroughly , checked all related components , checked float height / drop . all checks out good imo . no debris was found in any passages etc . 2. Cleaned and re-oiled the air filter . 3. Replaced spark plug with new NGK , played with plug gap as a test . regapped plug to OEM spec then reinstalled . 4.The spark plug always seemed to come out looking dry (lack of fuel) Removed fuel tank petcock and checked for a plugged line , but checks out good . Good fuel flow ! 5. Fuel was drained out of tank and carb , replaced with new Premium Shell fuel and proper mix at 25:1 using good quality 2 stroke oil . 6. Removed cylinder , installed new Wiseco piston & rings , fresh gaskets , honed pot . Piston to skirt clearance was a tad out of spec , but still runs and has good compression .Checked the reed valve while apart , looked fine too , no problems that i could see . 7. Checked for bad / leaking crank seals . No indication of leaks were found . Engine idles smooth , when warmed up is very responsive when you blip the throttle . And , so my problem still exits . I'm by no means a 2 stoke tuning wizard , so i'm here to ask for some help . Thanks in advance for any help / input .
