480r cov. need help

[Preddy05]

I am looking to turn my 83r into a 480r so i can keep up with the newer quads but i need to know some stuff. First off i was looking at pics of the cr480 and the motor looks really tall. Will fit into the 83r frame? and if so what other mods need to be done? motor mounts? pipe? what other stuff?
Thanks for all your help.

yes the motor will fit you need a 82-83 480, you have to make new motor mounts and a custom pipe has to be made, it is also advised that you go over the frame gusset n brace it up some, extend the swinger, i am currently tacklin this project dont get the motor till the 15th, when i do get it ill let you know more

[Preddy05]

Whats the diff. between the years of the motors do you know? atleast now i know that the motor will fit so now i'll have to start lookin for a motor to buy. Any idea on Where i could find an extended swinger?
Thanks for the info MTS.

theres no diffrence really, just they only made them for like 2 years 83' 84' years i think, they gota be RIGHT side chain drive, as for the extended swinger your gona have to search high and low on ebay and everywhere or just extend it yourself which is what im gona do

[Preddy05]

I have seen extened swingers on ebay before but not very offten so i'll keep lookin on their for one. where you just sayin 82 or 83 motor because you know its left side chain drive? thanks for all the info you giving me.

I was lookin on ebay and theirs a cr480 bike for sale and it says its a 4 speed...are all the 480's 4 speeds?

[MTS]

yes they are, they are known for there ungodly amounts of toque for the bottem-midrange but then they kinda fall flat on there face on the top.....im going to fix this problem when i build mine get all done out and a good pipe heh

[Preddy05]

i didn't know that they were 4 speeds what would you have to do with the gearing to make it have a good topend speed?
front sprocket?
rear sprocket?

Thanks for all the help.

it really depends on how you build the motor or if your gona leave it stock, stock gearin for it is 14/52 which gives you alot of posibilitys to play with, also when you have the pipe built it will change the whole tune of the motor, the stock 480r pipes where kinda skinny lookin for a 2 stroke if you ask me lol

[Preddy05]

thanks for all your help!
looks like you did all your research for this project

just about any swingarm builder should be able to make you a swingarm , i just wonder about the choice of motor why not use the water cooled engine? course i guess you use what you have

the water pumpers have left side chain drive, air's are left among other things there is one water pumper that i have seen in a air coold frame and it was a early cr250 with the right side chain drive....as for the swing-arm, if you can weld and use a grinder, you can extend a honda swing arm there like the easiest swinger to extend
