I have a 79 yamaha SRX 440 that I picked up the other day. This was a once in a life time deal for me- the original owner had this sled in a barn for over 21 years-I spent half a day helping him get to it. anyway-he sold it to me- IT'S COOL.
Does anyone have any decals for this- I am looking for the SRX one for the windsheild and one for the lt side of hood. also looking for any books and production numbers.
I also have a problem I can't figure out-when it starts-the headlight and tail-light come on for about 1/2 a minut then goes out-happens every time-i checked the plug-wiring- ANY IDEAS?

let me know-thanks:face-icon-small-hap

You need to go over to www.vintagesleds.com . That seems to be the hotbed for q and a along these lines.

A possible source for parts and info is Koch Performance in Wisconsin.

I bought a 78 SRX I was going to sell, then kindof started liking it.... :)

Man- That is some vintage RPM'S-
440 DART- I would love to just hear that baby rip.

For what they were back in the 70's and beyond- they did there homework on these vintage sleds.

TBWdracula2003-Thanks for the info.
I will try to locate one and replace that part- I just tried a new voltage regulator and that did nothing.
The Lighting coil sounds like the culprat.
