I'm game to look at this... But before you look at if it will fit... first need to look at gear ratios to see if there is anything to be gained. Or not. (6 gears doesn't always mean faster speed)
EDIT:
Here are the Gear Ratios for an 87 Tecate 4:
Primary Ratio - 2.818 (62/22)
Crankshaft 22 tooth
Flywheel 62 tooth
Transmission
1st - 2,357 33/14
2nd - 1.750 28/16
3rd - 1.388 25/18
4th - 1.150 23/20
5th - 1.00 24/24
6th - 0.880 22/25
Final Drive Ratio - 3.00 (39/13)
Sprockets
Stock C/S - 13 tooth
Stock axle - 39 tooth
Overall Drive Ratio 7.440 @ Top Gear
Motorrad:
Okay ran the numbers in gearing commander..
IF you just swap the tecate 6 speed into the 500.. and gear it so you have the same top end speed as stock kx500(14/47). you need to run a 15/45 sproket for all to be equal.
and by the time you do that.. First gear only has a 1mph differance between the two trannys... so you basically just end up with a extra gear somewhre in the middle..
NOW... if one could use the tecate trans, and somehow get 4th and 5th from the kx500 tranny to fit into 5th and 6th locations on the tecaty shafts... you would have a good tranny...... But now you are into very unlikley to work territory...
snoopjonnyjon:
If you don't gain a creeper gear at the bottom, or a higher gear up top, I can't see much use. I've never felt the need for a closer spread in the middle. Putting the 5 speed gears onto a 6 speed shaft does seem unlikely... very likely the 5-speed gears are wider.
Will the shift drums/forks fit?
