Love my 288xp. Got it as a complete basket case. Stripped screws everywhere! Anyway, did a base gasket delete, cleaned up manifolds and epoxy them together for cleaner flow. About a 70% muffler mod and a longer decomp valve. Ran it with a 28" bar for a while but it ended up being my everything saw, so now it's got a 24“ and an 8 pin driver. Probably going to eventually look for another candidate that can be made to look perfect, as my example was ridden hard and put away wet.
