CR 80 with 125 motor

92blaster · 10-25-2009, 09:15 PM

Well i havent seen anybody on here yet with a 125 motor in their 80 so i figured i would show how mine turns out so maybe someone would want to do the same thing.. well heres what im gonna use for the swap a 1989 Honda CR 80 frame (got complete bike for $250) and for the motor it will be a 1982 Suzuki RM 125 (got complete bike for $250) so this will be a relativly cheap project i have a deadline of 6-7 weeks as this is a school project so you should see results in the next month.. (pictures tomarro) i got the 125 running today so before i tear the motor out i have one question on lighning up the motor in the new frame.. i know you dont want it to sit to low in the frame or to high.. how do i measure this angle the motor is at currently????

id just measure on the suzuki the distance from the frame to certain spots u will remember and c if u can get it to fit in the cr that way with the measurments increased or deacresed but keeping all the measurments in sinc idk another word with the measurment moved, in other words if u have to move one measurment move them all to compensate for it

Should be a fun bike. I would call a local custom bike shop. Tell them is a school project im sure they wont give you any problems.

well i got the swingarm in today only had to cut one side of the swingarm.. i see one major problem though i wont be able to put an air filter on the carb i planed on using a uni clamp on but there is not enough room between the carb and the shock.. hopefully when i get the bottom mounts cut out and in the right spot i could squezze 2 more inches right now i maybe have an inch

I've seen this done to an 85 before using a cr 125 motor, it was much newer though. I can tell this project is gonna turn out awesome!

hey thanks i hope it does to with how well this is going so far i should have it done this month.. and i wanted a 85 but they were expensive still with junk motors so next year hopefully i will be putting a big wheel kit on it and the better 98 or whatever year they started the big tube front shocks and the non rezzie rear shock but thats only if i do well this year racing the q-racer
