Satsol67 Posted May 2, 2007 Report Posted May 2, 2007 The best way is to do a compression test. That will tell you if its rebuild time. The cylinders need to be within 10 lbs of each other and once it gets to 100 lbs or below its rebuild time. As for Wiseco you will find that most of the people here use them. If the rebuild is done right and jetting is right you shouldnt have any problems with Wiseco (thats what I used for all my rebuilds). FYI Vito pistons are still made by Wiseco if I'm not mistaken. Get a good compression tester and check it. Hope this helps. Quote
woodwardspecialties Posted May 2, 2007 Report Posted May 2, 2007 we have a few different piston setups on clearance this month (until 5/25).... Pistons are personal preference. Wiseco, Vitos, JE, ProX all great companies... Select Vitos setups are 35% off Click Here for Vitos Click Here for Wiseco Quote
Bansh-eman Posted May 2, 2007 Report Posted May 2, 2007 some people swear by forged pistons some poeple hate them... the thing is with a forged piston ( weiscos) you cant just start up your bike and take off.. you need o let the motor heat up before you take off.. the metal take longer to expand and if you run it cold then you are generating alot of sudden heat that can cause your motor to seize... you will find that most people run weiscos when they rebuild... they are race proven and they just plain ass work! so big deal you need to heat up your motor before you take off... start it up and let it run while your getting your gear on and go... as for how often... it all depends on how well you maintain your bike... if you change your oil regularly your going to get more time out of it then someone that doesnt, if you run it lean your going to drain some time as well... so there really isnt a set amount of time... but like Satsol said... get a compression tester and that will tell you when your ready...

2strokinit Posted May 2, 2007 Author Report Posted May 2, 2007 also...do i have to use the stock size kit? or like..what are the different sizes?or does it depend on my motor work? should i get any other work done while it's apart? I really am not lookin to spend big bucks right now...but my tax return should be back soon..so that will help out... i really would like to spend...no more than $600 total....my mechanic told me it will cost me 350 to rebuild the top end..i forget if that included parts..which are around 150ish?right.. hey guys.. i really appreciate all the advice i've gotten since joining HQ...thanks alot!

Bansh-eman Posted May 2, 2007 Report Posted May 2, 2007 dude buy your self a clymers and do it your self... it is killer ez! 350 to rebuild a topend is stupi if you ask me! its so simple you would want to slap your self for even thinking of paying someone else to do it. as far as pistons sizes go you need to bore / hone your cyclinder to clean it up... depending on if you have to bore it would determine what size piston you need... you can buy weisco pistons for like 120 bucks...

2strokinit Posted May 2, 2007 Author Report Posted May 2, 2007 to bore or hone my cyclinder is where i wouldnt feel comfortable/capable...as far as everything else...it could be done in my garage with regular tools? if it was your first time taking your head off and opening her up...would you bore your cylinders since it's apart?..is there a big performance gain after having it bored?

cam2 Posted May 3, 2007 Report Posted May 3, 2007 (edited) you will find that most people run weiscos when they rebuild... they are race proven and they just plain ass work! so big deal you need to heat up your motor before you take off... start it up and let it run while your getting your gear on and go... this is what i do, and i've ran two sets of weisco's in two different sets of cylinders with out any issues. i personally let everything i own warm up before i run it hard. as far as everything else...it could be done in my garage with regular tools? yes, it's rather easy, a little time consuming but easy. get a clymers manual, it's very handy. you definantly want a good machine shop to bore and hone your cylinders to match the new pistons. this assures a perfectly round bore and the correct tolerances of the new piston. as for the install... it is easy... a clymer manual would guide you right through it. so true. get a comp gauge and check your compression before you do anything. if you need to rebuild the top end you may as well get the cylinders ported while they're off. even if it's just a mild port job, which i beleive you can get it done for around $250. if you need a topend kit and port work give jeff at fast a call, he'll hook you up with every thing. http://www.farmandsandtoys.com/services.asp if you need help with anything shoot me a PM. i live in north tampa just down the rode from LOL.

Satsol67 Posted May 3, 2007 Report Posted May 3, 2007 Dont make the mistake that I have made in the past and guess with size you need. Get the compression tester and if it is time pull the cylinders off and take them down to the machine shop so they can tell you what size you need. Then you can order the right size. Once the new pistons come in take them along with the cylinders back to the shop and have them fitted. Trust me you will save alot of money and time doingt it like that. If you have the $$ to get it ported this would be the time to get it done. If this is the case I would send them off to someone like Jeff at fast and let him take care of doing the port work and fitting the pistons. 600 buck is plenty for a top end rebuid and port job the only thing you will have to do if rejet your carbs after you put the top end back together. The top end if VERY VERY easy like everyone has said plus you get to learn and if you have any question there are alo of poeple here that are willing to help. Good Luck. Quote
