[QUOTE="mxwilly, post: 709275, member: 39736"] I had a 91RM250 up until the spring of this year. Spent a lot of money getting it n shape in 2000, but it was a solid bike. I wish I had my jetting settings for you, but i sold the bike, manual and all. I know the main jet was a 340, cause i found a receipt for that. not sure about the rest. I had it dyno'd and with the shorty silencer i made, it had 42HP. not bad for an old girl!! visit http://ca.geocities.com/willysrm250 for some pics! i've tried FMFracing jetting settings on my 02 RM250, and they worked awesome. For your info, they recommend the following for a 91 - 55pilot, 360main, 60 needle with the clip in #3. as for the bike not responding, my wife's yz80 had a similar issue....her reeds were damaged but more importantly, the silencer tube was crushed from a fall and it wasn't running due to that. I spent so much time on that bike, monkey'd with the carb etc.... then found out it was the silencer causing the headaches. Hope you get the 91 rolling, it was a fun bike to own. _________________ thanks to my sponsors: John Hehn Construction, Ram Services Asphalt Maintenance, mxforum.com, Fulle Twisted Clothing, Rage Grafix, Motopark Racing, Engine Ice Coolant [/QUOTE]
