i am buying an 1100 this week its an 82 like mine and am doing an engine swap i have an 850. any tips ,concerns,help,or friendly advise? i will follow up with starting pics of the (new)bike and my progress

Sounds like fun! My understanding is that the drive shaft is slightly different so you will need to move that over. The Ignitor is the same so you shouldn't have to mess with the wiring. The airbox may be slightly different, or the boots maybe.

Enjoy!

thanks i am getting it for 250 with no title just a parts bike so i will get what i need and sell the rest it has 13000 on the odometer aprox been sitting for 2 years is the carbs the same as my 850?

Hi,

The 850 uses BS32 carbs. I think the 1100 uses BS34 carbs.

I have it on good authority that the 850 and the 1000 are pretty much the same frame and the engines swap without much trouble. You may be in for a little more logistical challenge with putting an 1100 motor in the 850 frame. As Mr. Nessism says, you'll at least need to move all of the drivetrain over. Keep us informed.


Thank you for your indulgence,

82 and on 850 and 82 and on 1100 frames are the same. there was no 1000 after 81, the 1100 took its place...

[elevatorman71]

so what do they mean by moving the drivetrain over to make it work?

[BassCliff]

Hi,

Along with the engine, take the u-joint, drive shaft, final drive, etc, from the 1100 and put them all on the 850 frame.

Thanks for the clarification Mr. TCK!

[rustybronco]

but one question when did they swtich over the tube fuses to the blade fuses ?

'82 I think.
my '80 has glass tube fuses, the '82 has blades. (gs850g's)

[elevatorman71]

my 82 850 has glass to i was just wondering if i got a different year no title with the bike so i was not 100 percent sure
