Could someone help me on how to mod an 86 frame to fit the 89 engine...

Cut out the lower portion of the center tube ahead of the engine and weld in a wishbone. Or wack it all out and add two straight tubes up the sides where the engine mount plates want to go. Just look at a 87 + frame pretty simple.That's really the only major modification.

BlackndWhite, I'm looking at doing the same thing. The only mods to the frame are just as Iceracer said cutting out the down pipe and welding it into a upside down Y then making motor mounts.

You would also need an 87+ carb and CDI box. Best way I've thought of doingit is to cut the frame piece out so you can set the motor in the frame then place the parts to be welded on then remove motor and weld. Its actually a failry simple task IMHO.

ok yeah i had a general idea just wanted to see what the best way would be.. and i figured i needed the 89 wiring

and what is the difference in the harnesses on the parts websites... would i matter what one i get

Chuckie25 · « **Reply #6 on:** December 16, 2013, 06:17:08 pm »

the wiring harnesses are close enough that an 85/86 harness will work with a couple small modifications o the kill switch wires to move them away from the throttle housing. In my build thread i have stock and cut down harness diagrams posted for reference and for if you want to eliminate lighting circuits.

what should i do if i have 86 controls and 89 engine

Dutch_Rutter · « **Reply #8 on:** December 17, 2013, 02:39:28 pm »

Everything should still work the same, Just splice in the 87+ CDI box to the correct wires. the newer motor can use the same stator as the older. the only thing that I'm not sure about is if the older throttle cable will work with the newer carb.

ok but how do i know what model letter to get

Chuckie25 · « **Reply #12 on:** December 20, 2013, 09:08:00 pm »

Pretty much all the bearings are the same from 85-90, chassis wise.

Look at the tenth letter in your vin on the frame.

F = 85
G = 86
H = 87
J = 88
K = 89
L = 90
M = 91
N = 92

hey chuckie could you post a link to your build.. i think im going to try and make my own harness just enough to make it run

GrkGuy · « **Reply #14 on:** December 23, 2013, 07:58:56 am »

BlackndWhite · « **Reply #15 on:** December 23, 2013, 07:41:39 pm »

thanks chuckie that helps out...

what parts from the 86 will work on the 89 engine wise..
cuz when i got the frame i got a bunch of 86 parts with it

can i use the 86 spark plug wire

Dutch_Rutter · « **Reply #18 on:** December 23, 2013, 09:33:39 pm »

I think the plug would be fine, same goes for the stator. But you will need the carb, cdi, carb boot and reeds and cage from the newer bike.

That's the same boat I'm in right now. Slowly picking up parts, and rebuilding the motor.

Ok going to bring this back from the dead... haven't done anything with it and today decided to finally get going on it. ..
Just want to clear some things up... the back of the motor mounts into the swingarm
then can someone give me some measurements on where the down tube meets then rest of the frame so i can put the new piece in the right spot...

Chuckle is the guy to talk to about this. Send him a pm. I bet he can chime in on this.
