bigboy400ex, I weigh in at 220 lbs. so more motor was good for me also. In addition I put on the WB E-series pro meg system, that's the headers on back to the muffler, which has 18 discs (I added 6 plus the original 12). I added a K+N filter w/skins, airbox holes, and dropped a tooth on the front sprocket and I obviously re-jetted it. I've been looking into the larger oil rez like stated above, I think that will be next purchase. I've added other things but that is all that have to do with gaining ponies. I stuck with the stock cam because I didn't see any large gains from changing it and didn't add rev box because most of the power from this mod comes in the low end like I stated earlier, and revving it higher would do no good. Hope this helps some.

 

IF YOU GO WITH THE 440 KIT, BE PREPARED TO CHANGE ALOT OF OIL...IT WILL RUN EXTREMELY HOT! ! ! !! ! ! ! ! I HAVE A 426 KIT PUT IN BY PRO FAB, AND AM EXTREMELY HAPPY...BUT IT EVEN RUNS HOT...YOU WILL NEED TO RE RING THE MOTOR AFTER EVERY 200 HOURS OR SO, CAUSE IT WILL SMOKE, FROM BLOW BY(DUE TO BURNT RINGS) AND WILL PASS BY YOUR VALVES...IF YOU GO WITH THE 416 OR 426 KIT, YOU CAN GET THE 39 OR 38 CARB, I FORGET, AND HAVE BOUGHT THE SAME PONIES AS THE BIGGER KITS WITH OUT A NEW CARB,AND RUN ALOT COOLER...BUT A GOOD EX CARB WILL RUN YOU ABOUT 600$, GIVE SCOTT A CALL AT PRO-FAB, HE BUILT MY MOTOR, AND IM HAPPY, HIS NUMBER IS IN THE BACK OF DIRTWHEELS..

 

FYI - FWIW...

I think I read somewhere that if you have Curtis Sparks re-sleeve your engine, that they will bore the cases and use a non tapered sleeve....

 

How much and where can I get one of those 3 quart oil resivors?? Because I am so sick and tired of changing the oil everytime I turn around. Actually, I just changed it the other day, and within about 6 hours of ridding, it was already smoking. And the bike is only about 11 months old. Thanks

 

Use better quality, heavier weight oil. 5w30, 10w30, 10w40 oils won't cut it....

A better oil reservoir won't hurt either though

 

I love my pingry 3 quart oil rez, also my mobil 1, 15w50 rules... killer combination

 

yes, go get that 440kit, it makes all the difference in the world. I beat raptors and banshees w/ mine all the time.

 

Is there a increase in vibration.
