My opinion you would've been better off spending the money on a Paul turner or for a little more then that carb cost you an AAEN pipe. Fmf are pretty much a chrome stock pipe the only thing they change slightly is the sound and add probably 2 hp or less. Getting a set of vforce v2 reeds and a Paul turner pipe will livin that beast right up!

Just my .02 but if your going for new reeds get ahold of Hall for his V2 setup and spacer.Sweet setup and I run one on my 87 250.The PT pipe is a decent pipe but take it from me better to spend the extra on one of the high volume pipe.Hall,Q pipe,Aaen,DCS,old LRD,etc.I dragged my feet about spending the $$$ on one the heavy hitters.Got a great deal from a member here on a V1 Q pipe and couldn,t be happier.

If your on a budget and thinking used a PT pipe can be found relatively cheap.If you were thinking of buying a new PT pipe you can find a good used high volume pipe for almost the same price or even some new for a tad more.

That is one sweet looking carb.Unless your doing long WFO runs I would think you,d be fine with the small fuel bowl.I,m running a 44 Lectron with no issues so far.Maybe the dune guys wot for long periods may be different.As far as the air filter there is an adapter for the stock airbox that allows the use of a bigger clamp on filter.I run in some mud time to time and went that route so I could retain the OE airbox. Keep us posted on the carb,interested to see how it runs.

Quadman is right

Damn if I didn't get that urge to build a faster 500

A work in progress... looking at an open filter system next

I was going to order some OEM reeds today. Is there a quick way of telling whether we  have an LT500R or LT500RL cylinder or do I need to take the carb off and get to the reed cage to be 100% sure? I just realized there are 2 different sets of reeds for the 87.
