It seems I may have been misunderstood since two riders seem to have problems with my posting. The individual who first posted on this page asked in his second posting…..
“yeah, I think it might be 396, but I’m not positive but I might have to replace my crank, and it’s like the same price to go that route than it is to go the stock route, and I talked to the guy at alba (not getting it done by them, or from them) but he said they run it all day long with no problems, and I just some conformation on that you know?”
It seems the individual fearnofish06860 did not know if his crank was bad and was considering getting a Hotrods-Stroker if his crank was bad because he believes it to be the same price as stock (or stock Hotrods crank). Well it is not the same price and if money is the problem, which it sounds like it is, than a rebuilt crank would definitely be the way to go. Just plug in rebuilt-ATV-crankshafts into Google and see how many companies do this work cheaper + parts than buying any of Hotrods crankshafts. Not to mention the Stoker piston alone is $250.
I do understand a Hotrods-Stroker is cheaper than if you had your stock crank stroked (most of the time). I was not trying to imply that stroking a stock crank is cheaper.
Higher compression and temperatures (strokers and big bores) can cause premature warping of the cylinder head. Upon cooling to room temperature, the head and cylinder contract which can cause a leak at the head gasket the next time you start your cold engine. Most times (for the warrior) just tightening the head bolts can fix the problem. So yes indeed a head gasket can leak (seen it many times). Not that it’s the end of the world…just a pain in the ass when you just want to load the quad and get riding with your buddies.
For the warrior,+ 4mm and most definitely +7mm stroking is what I would call extreme. Every man has his own definition. I guess extreme to some would be so large that it requires increasing the deck height and getting an extended cam chain. For the “stock” warrior head and cylinder I think +7mm is extreme. I also understand that many have reliable bored and stroked motors but I think most have issues…especially if the individual does not maintain it….clearances etc. I also believe most use an oil cooler…..why not use one with $1000 invested already?
The easiest/simplest way to increase power on your warrior is and Edelbrock Carb. It is very expensive but easier than (for the amateur) installing a cam, springs, checking clearances, and timing etc. Although a performance cam is awesome you really need to be honest with yourself on what type of riding you do. Don’t buy a race cam if you’re always in the low to mid range. With the edelbrock it doesn’t matter because it’s always crisp with enhanced power throughout the entire range. Therefore, I think an Edelbrock is the best mod you can do.
