Greetings John and
Amusing intro...
No idea about paint colours mate but i know of a good painter if you want his contact details?
Me? well I just rattle can the little beauty
The red light is the oil level alarm, but it's on constantly when in neutral...as a bulb check
The headlight only works with the engine running, but the pilot works from battery
The length will affect the ride height, if its too far different it will either make it difficult to get your feet down, or the other way round, could cause bottoming out...just guessing though
I dont know the answer but why not compare the length and bolt / pivot sizes for the two models, and if necessary make an adapter sleeve if required, also compare the two bikes to see if they have a similar linkage arrangement
yeah some of the XT's are sumo's
