[QUOTE="RM250Rida, post: 150355, member: 23268"] Just got the parts today and got it rebuilt tonight. I ran the cylinder and head up to the local suzuki shop. They ran a ball hown through it cross hatch it and deglaze it and also lapped the head for me, for free. I also got a new spark plug there and they told me I should get a BR8ES instead of a B8ES because the R (resistor) ones are harder to foul. Is this true? Well I got it warmed up and played witht he throttle for 5 mins then turned it off and changed the idle screw and the pilot air mixture. Put on some of Factory Effex's super pro 8" numbers and waited about another 2 mins and it was fully cooled. I started it up and warmed it up again then waited another 5 mins then shut it off. I then let it fully cool then started it up and ran it at 1/4 throttle. then let it cool, started it back up to operating temp and ran it at half. I pulled it back in the shop and am letting it sit until tomorrow. Tomorrow I'll probablly warm it up and run it at half throttle for about 20 mins then let it cool completely. After that it should be ready to rip. Hurt my foot pretty bad kicking it over. :p My friend wants to race me tomorrow against his 98 CR250. It's completely stock, even the piston. I have fresh wiseco, cometic high comp. gaskets, pro circuit pipe and silencer, Boyesen rad valve, and twin air air filter. I also have a one tooth smaller front sprocket so Im goign to lose some top speed. He's also a better rider. Ill let you all know who wins. By the was my bikes a 92 RM250. Think I can take him? It'll probablly be just a darg race up a paved road by his house. Then we'll go down and hit the gravel banks. Cant wait, my bikes ready to go. [/QUOTE]
