Looking for specs on a SRV 540 with a KEIHEN carb. Not sure what size the carb is...looking for jet sizes. Also have a DG muffler on it. Any input will help...trying to get my old betts up and running again. Thanks

I had one of these with the DG pipe, I also subscribe to dyno tech which did a pipe shoot out on the 540. DO NOT run over 7000rpm. !! that pipe goes right to deto. makes good power just make sure you have heavy weights in it. Mine had a comet 102 and it called for the yellow spring and 52gr weights. mj ???? 140 ?
