top end rebuild suggestions


Recommended Posts

I need to rebuild my 01 shee top end I have about $350 to spend on parts and I need to know the best route to take, the reason for my rebuild is that my friend has a 05 440ex with hot cam, heavy duty timing chain, and a full exhaust, we draged and i lost every time and I didnt think thats the way it was supposed to be. That is unexceptable to me, any suggestions are apprietated. Thanks.

if it is low on compression doing a fresh bore job will do lots of justice, also porting it will add some power, i ported mine myself and it is very quick, i wouldn't get beat by a 440ex at all. what else is done to it?? oh yeah, passion racing does a topend job(bore,hone,pistons,rings,gaskets,orings) for like 245.00.. thats a great deal, and jim is an excellent builder. if u can afford it his portwork kicks ass also, look up wacko on here, he just had a motor built by jim.

well i have never had a stroker, but in all they add mor tourqe and power. you will need to get with a builder on that one, your cylinders will need to be ported for the extra stroke to gain full advantage from the stroker, and u may need to have your heads domes cut to reconfigure the squish, but if u have the cash it is a great idea.

Strokers are fairly easy to install. I just dropped one in my shee. I'm still waiting on a flywheel so I have not had a chance to run it yet. To install a standerd hot rods +4 stroke + 5 rod, you will have to have a stroker crank, spacer to go under the cylinders, special pistons with the wrist pin moved up 5mm(wiseco 795), gasket set, yamabond/hondabond to seal the case back up, about 5 cans of carb cleaner to clean all the motor parts, it's best to also have the cylinders bored. as far as tools, all you need is a socket set, screwdrivers, a flywheel puller, inch lbs torque wrench. I might be forgetting something but I think that is just about it.

From the looks of your mods you still have a few bolt on modifications missing.Advance timing plate,reeds,milled head or a cool head.Then a good port job,bigger carbs,If that aint enuff then comes the crank and what not.Is he beating you bad?

If you get rid of the spacer plate and get the porting the 4mm deserve without the spacer plate, its a whole differant story and then the stroker run with full potential.
