Speedometer\ Tachometer ????

[bbs1980xs1100g]

I have an 1980 xs1100g the speedo maxes at 85mph and the tac maxes at 10.5k rpm. I have extra parts off a 1977 750Special. The 77 750Specials speedo and tac max at 130mph and 13.5k rpm. Many parts from these bikes are interchangeable. ( rims,rotors, oilfilter housing,rearend etc... (back caliper is the same. Front Special calipers are different. Can I use the special front calipers on an 1100g ? and how difficult is the switch to the bigger tac? ( special speedo is round and the xs1100 is square, or is that just a faceplate thankyou Brian?

Sorry you can't use special front calipers on a standard, totally different mounting for the calipers. The speedo should work but the tach will only work if it is an electronic tach, if it has a cable you can't us it on an XS11.

I just pulled the 1977 yamaha 750 special speedo out of the old box and it reads 140mph and 12k rpm , my xs1100g tachometer does not have a cable, just wires, the 750 special speedo is round can I put it into my xs1100g square case? Thanks again Brian

You might be the first on to try that, Brian,

An alternative is the Sigma bicycle computer BC800, BC1200 - gives very accurate speed and odo, max speed, avg speed, etc.

I have the bike stock just tossing up ideas of a little modification.
