i have a 1991 yamaha warrior with k&n air white brothers E pipe what sould i do next to make it faster

 

get the j&e piston that makes it 366cc and a stage 1 hot cam, after
that probably a dyno jet kit

 

what size tires are u runnin on your warrior

 

The stage 1 Hotcam won't do anything but **** your engine off. If you want power, get a Webcam 84 grind (.430") with the valve springs. Get some 20" rear tires if you haven't done so already (Holeshot GNCC) 20x10x9 will make a big difference.

 

get a web cam they are the best out their. Also look at 4 stroke tech for sim big bores for affordable prices and powroll is another one.

 

I'll tell you like I tell everybody - don't waste too much money on trying to make a Warrior fast. Just sell it and buy something else that is faster.

How fast are you looking to go? I had one with the mods you have plus the JE 366cc kit ($200) and the Webcam ($260 with springs) and it ran real good for less than $600 for those mods and it would run about 65mph with 20" tires and a 14 tooth front sprocket.

You could get a port job ($200-400), larger Kibblewhite valves ($100 installed), or a FST +10mil 446cc stroker (around $1500 installed) but then you are just throwing money away. I had one with all of these mods and a 15 tooth front sprocket and it would run about 70 mph.

 

If I was taking apart the topend and putting money into a piston I might have done different but I got the stage one Hotcam and am not dissapointed for 130$ and under 2 hours work. Only made a minor difference on top end but what do you want for the low $s and minimal work. I wouldnt bother with such things on a Warrior till I replaced the stock suspension though. That made more difference in my speed through the woods than any cam could have. I wouldnt have even bothered with a cam but Im close to beating my freinds Z400 to 60MPH . If his 05 Z400 was passed even momentarily by a 87 Warrior it would just wreck his whole decade. [img]i/expressions/face-icon-small-happy.gif[/img]
