$1,100+ for a toop end?

[musturbo]

My dealer wants over 1100  to fix my 04.  $600 of that is labor.  Bike needs a cylinder(or bored and replated) piston kit, gaskets.  I called phat head racing and they said $300  for an iron sleeve and  full port.  THey guarantee the sleeve.  Was also going to buy a coated  vertex piston .  Can you guys give me your thoughts or recommendations  please?    Total ride time on the bike was 1hour>

I can't find any prices o his site and got an answering machine when I called.  Mac wants $294  for the cylinder and top end kit.

How damaged is the cylinder? Most of the time it is reparable through welding and re-plating. That's what I am doing with my cylinder now and I am being charged ~?150 for the lot. Not much of damage though. Add another ?120 for the new (Wiseco) piston and ?40 for gaskets and o-rings and stuff. So the complete top-end re-build is approx ?300+. I'll do all the work myself except the welding & plating .

The cylinder will then be standard 86 mm, no oversized bore.

Sounds a tad expensive what you have been quoted, then again, I don't know how badly damaged the kit is.

$500, for a 520cc big bore, replated, ported to your desire, head mods, and the piston kit/everything. It is worth it![/img][/b]

Call Rick Peterson Motorsports for replating.  His shop does the work for almost all of the factory teams, and he has a quick turn around.  In fact, if he has a cylinder in stock that fits your bike, he will just swap you, so you can be back riding by the weekend.

On the sleeves, I tried one and will NEVER try another.  Lost power, and the bike just plain sucked after the installation.  No matter what the warranty, they can't give you your unsleeved cylinder back so you can just do it right and have it replated.

On pistons, just use a ProX or Wiseco piston, and you will be one happy camper.

Maybe your dealer figures the since the oil companys are getting away with screwing the public that he'd give it a try,$1,100.00!Is he out of his mind?Go with the plating and if you can do the job youd save the labor(theres always good help here)and Ive had good luck with Wiesco pistons.Why'd it seize in the first place?

I am working on a top-end rebuild description together with Doordie. I think it will come in handy for you if you are planning to do this yourself. If you can throw a wrench - you can do this. No special tools are needed, just patience.

ETA a week or two, just missing some of the assembly pieces and some svEnglish. Most of the tweaks and inspection parts are already done including some KIPS fixes (thanks to Doordie).

I've been rebuilding dirtbike top ends for nearly 30 years.  It's not hard.  Don't pay someone to do it for you.  If a 15 year old kid and do it, you can too.

I am picking up the bike sat morning, .  I will take a look at the devastation myself and decide if a cylinder , bore and sleeve or replate is the way to go.  I was thinking sleeve  because I  have a reputable local place  to send it . I was also thinking it would last longer.  Again, I absolutely  am thankful for your input.  worse case I drop $400  for a cylinder.  Best case the sleeve works, my port job produces power.  I have a wideband o2  and a data logger I will try on the bike.  This time after the break in it is going straight to the the dyno to tun e.  I will post pics of the piston and  bore tommorow.

JOHN- please email me that   top end description!  I  think a schematic and torque specs should do it.  Just not familiar with the kips assembly.  Oh yeah,    $131   for diisASSembly.  My wife said, "what are you having  them do it for, do it yourself.'   Should have listened.

score!

Decided to have lancourt in alabama replate the cylinder and supply a coated pro-x forged piston.  While it is apart I am also doing a full port   and bringing the compression up a point.  Thanks, Guys,  will keep everyone posted and will post dyn #'s if interested
