Hi all,
Ok, here's the deal. I want to get a 10.5:1 stock bore, and a cam(hot cam, Web,..etc..) Will the added compression and hotter cam decrease my milage significantly on the 400ex? I'm running a 160 main now w/ mods listed below. I figure I'll have to bump up to like a 170 or so. I thought about getting a IMS desert tank, but frankly, I think they are hideous looking. I would also need to get a +1 stem to clear the tank. I can ride about 60 miles or so now with no motor work. We take LONG rides occasionally and I don't bring extra gas with me.
Here's the other thing...How do I know that a hi-comp. stock bore is going to be ok with a 99 quad, that's never been apart? Meaning...My 400 runs excellent now, doesn't eat oil or smoke. I do not know the condition of the cylinder walls. I don't want to bore to a 416 until it's necessary. I want to run the hi-comp stock bore untill the walls are shot....Does that make sense?
Any help is gladly accepted, let me know what you think,
Thanks,
Glamis
