Hey Bubba I have a 2000 explorer 400 with a Bubba ported cylinder, dyno port pipe, 39 mm. keihn carb, V-Force reeds, stock clutching, and 26" ITP 589 tires and I don't have any bottom end power at all. It won't even pull the front any more, I'm lookin for some tuning sugestions, could you please help me out?

 

is your belt ok?if its wore out you will loose alot of power

 

time for a clutch kit!!!

 

It does seem to slip alot when pulling things, but it's onlt 3 months old.

 

I had a Hotseat clutch kit on it, but it made it over rev and lose power, if they gave me the clutch kit I asked for it might have helped, but they only have one for their pipe.

 

no in the part when your ordering your suppose to tell them all your modifications or call them and tell them to make sure they know what your talkin about.

 

I told them exactly what mods I had and they sent me the same kit they have for any Explorer 400, I realy don't think they care much about what mods you have as long as they can talk you into buying their product.

 

What happened to ya hotjunk fan? I've seen nothin but problems with their products, this is with 3 different quads.

 

"stock clutching" there is your problem,you need a clutch kit along your pipe...

 

A good setup to try would be a red/yellow primary,stock weights,violet secondary set in the 2-2 position.You are looking at maybe $60 bucks.This would give you a very good starting point.Unless you know exactly where your pipe makes it's power it is hard to setup the clutching for it.Hope this helps.
