1987 vf 750 supermagna Australia

Hi there,i just bought a vf750 magna,I bought it off ebay..without seeing it and hoping the seller wasn't a bad seller..After seeing the pics I thought it looked good..and asked the seller had the bike been laid down at he guaranteed me the bike was clean no drops,,previuos owner had looked after the bike..
Well I caught a plane and when I see the bike ot looked ok..he started it and it sounded sweet..yeah..I just paid the guy and hit the road a 2 day trip back home..After looking over the bike again I noticed a rattle coming from the front 2cylinders,,at idle it's whisper quiet,,but rev it over 2500rpm and it rattles..I hope it's just the tappets..I need to sourse a special spanner berfore I crack the top open..I may need to replace the tensioner as well .1987 model magnas are they the same engine as the vf interceptor?.or are the cams the same as the sabre
also noticed a dent in the water pipe on the left side engine and the mufflers on the left side have been changed.bike goes very well and is very comfortable..1 other thing would a vfr engine fit into the frame without any modsd,,thanks:frown:
