need help with my 84 250r atc!!!

[thejake456]

i have a rolling chassis and was wondering if the swing arm from a 85 would fit on my frame? i wanna use the whole rear end from a 85 250r insted caus the motor that i have is an 86. and as you all probably know they switched the sprockets from the right in 84 to the left in 85. so you see my problem! please help me asap!!!!!

no it wont work way differnt and not even close enought to modifie easily to make work, and the shock mounting areas are drasticaly differnt as well.

big negative captian on that one

welcome to the site non the less!

[thejake456]

well is there any way i could just like flip the axle? or wouldnt that work either?

[thejake456]

is there any bigger motors that are older with the srocket on that side that i could stick in the frame? like an older 500r 2 stroke?

This doesn't help you at all but it is kinda related. Somewhere on the net I saw a liquid cooled motor in an 83/84 250R. I beleive there was one year of CR250 that was liquid cooled with the sprocket on the right side (same as air cooled 250R). Pretty neat.

Yeah CR450 or CR480.

you could flip the axle but your brake mounting points wont be right and its just not a feasable thing to do, plus there is no way either the 84 shock or the 85 shock would work on the 85 swinger in a 84 250r. unfortunatly the 2nd gen Rs have a tough swinger and rear suspension design to go around, were is my 85 250R has all 05 trx450R rear suspsion.

you may contact a company like HRE who could make you a new swinger for your air fooler, im sure there would be more interested at there are alot of 2nd gen riders here.

i was actualy trying to find a bigger motor. like a 500cc. does any one know if there is any sights where i can find aftermarket parts for it?

[SYKO]

also putting in a liquid powerplant wont be that hard but now you got to figure out where raditators and othe rparts go, plus the intake on the liquid goes to the left a bit where is the intake on the air cooled is straight back to the airbox. One thing or another you will be better off having a air cooled motor in the air chassis and the liquid in the liquid chassis.

lol this site post up a classifieds add, most members either have or no where aftermarket parts are located

a 300 kit is for sale right now for the air cooled motors.

[thejake456]

another question, if i were to just get a 84 250r motor. how fast would it go? if i put enough money into it?

[SYKO]

pm 1upfront, he drags a air cooled 250R when I had my 83 with a 300 big bore on it ,it was slightly faster then my piped and carbed 85 250R.

will going 90mph make you happy? then just regear it. Most air foolers top out around the 65mph mark, depending on where you ride you would rarely see that.

in my op the 2nd gen 250Rs are some of the best trikes ever built

this was my 83 I built and sold

[thejake456]

wow, yes that would make me very happy to go 90mph! but wont re grearing it take away from the power? and where i ride i want it to have power! well would they compete with a 250 2 stroke bike?

ps nice trike!!!

[SYKO]

no I being stupid about 90 mph, yes that type of gearing you will loose all bottome end and take off...

if you want power like hillclimbing and fast trails you dont need to be able to go 90mph you want tourqe and low gearing

[thejake456]

Yeah CR450 or CR480.

i would really like to find one of these. my 250r would have to ripp if i stuck one of these into it!
