what piston

[fmxr47]

so im due for a new topend, im getting it bored for $60 is that a good price?, also im wondering what piston to go with, i want one that is lighter so the engine will rev faster, and how much does it cost to get a flywheel lightened approximately? thx for all your help guys it is always appreciated!

 

[fmxr47]

oh, im not sure what size i need yet, im hoping its just one size up, im just wondering what piston is good and reasonably priced, thx again

Usually between 50 - 75 bucks for a bore & hone on a jug is about right.

All pistons are made from aluminum, there really is no "lighter" pistons. The only way to go for a piston with these motors is a Wiseco forged piston. They are about $50 - 80 bucks depending on the size needed. The old addage of you get what you pay for really applies here.

I paid $40 bucks to get my flywheel cut, that is about the norm.

wow my local machine shop wanted way more for the flywheel shaving, thx for the info

 

[fmxr47]

ill see if the place thats gonna do the bore will shave flywheels thx

do you know where there is any riding out by parma area cause im moving out there starting the first week of july, i might take my quad to a storage unit or im gonna just leave it at my dads house in medina

yea u should def go with wiseco but with my bore .40 over n my piston i had to spend a total of $200

 

[fmxr47]

why so much?

 

[ClimbAnyHill]

$200 is way too much for a top end kit!
Get it from John @ RJATV.com for $66 bux >> Engine - Wiseco Piston Kits - ATV - Yamaha - Blaster
Send your wheel to Denny @ Flotek Performance for $20 >> flotekperformance - Home

All that under $100, I too pay $60 for bore & hone!

 

[I2fast4u]

because i gave it to my local yamaha shop n they dont have the equipment to do it so they have to send it off to the honda shop so they jak up the price so they can get their money outta it

 

[fmxr47]

find yourself a decent machine shop

I though denny was $40 bucks for the flywheel cutting? I could be wrong, and probably am lol. It was last year when I had mine done.

im a lil confused, is a 240 kit from someone like vitos ( i know there crappy im just using them as a point) the same as ordering a .40 over wiseco piston and having it installed?

im asking as far as the performance part of both, or does the 240 kit come with extras?

 

[fmxr47]

a 240 is a 72mm piston, where.040 is like 67mm or around there, 240 is the cc its a big bore

 

[beachblaster]

so going x amount over is a cheaper alternative then buying the 240 kit?

 

[fmxr47]

yes,your stock cylinder will only bore out to a 68mm or like 68.25mm so i dont see why the 240 kits are so expensive, but they are

 

[1nastynotch]

I have the vito's 240 kit on mine, denny @ flotek ported it for me. It is an ok casting as long as you get it ported. I wish I would have just did the stroker crank though. You will gain a lot more power from a 3mm stroker crank and a good port job on the stock jug than a 240 kit any day.
