any tweaks to the fuji 500 with flatside carbs........ like to add a little snap to this nice handling machine.... but dont want to harm it either... fuji engines any good???
thanx

EV?
id spend more time on clutching and gearing. mike

:devil: First of all start with jetting see how the pistions and spark plugs are buring a nice card bord color is what u are after then start with the clutching try 10m5 polaris weight's 49.5 grams with a polaris gold primary spring use a gold secondary spring with a 40/36 progrresive helix and leave the stock gearing for trail driving that's a very good trail set up and if u want a race set up just email me at rob_md18@hotmail.com and then start playing around with you'r supeson for good handling happy sledden and for the record if u put good gas and lot's of oil to her you'll never burn that engine out my friend has a 1996 indy 500 with 11000+ miles on it and he's ruff on it and it still runs great.

I don't think there's a more dependable motor than that one. Unless of course you
tweak the jetting lean.

Believe it or not.....i blew a crank in that engine with only 500 miles on it.........polaris sent me a whole new engine for a replacement after i did some yelling and jumping though.... my new engine only has a few hundred miles on it now!!..........

You should give Chopper City Sports a try. They have a cluth kit that will make her rip. They have all the info you need for whatever set up you want for that fuji engine. CCS is owned by Marv Jorgensen the guy who has JAWS the world record speed holder. He knows how to go fast.

is it exhaust valved?????????

i dont beleive so.......its just a indy 500 edge......

polaris blue spring, 10-62m weights, stock helix, epi red secondary spring first hole. gear for 95mph full shift 19/42 or so. mike
