Title: Site window Piston
Post by: mwalker04 on September 16, 2010, 01:59:59 AM
Greetings, I've been rebuilding my 5 for the last couple weeks, frame off.
The problem is, I would like to do the top end with a site window mod, and cant get ahold of Jerry @ jfab motorsports.
I've called, Left Voicemails and emails. Cannot get ahold of him. Does anyone know anywhere else I'm able to order a site window piston? Please call me at 480-809-767(four) or email me at mwalker4338@gmail.com

Thanks all.

I see, I will have to hold off on the engine for now, there are plenty of other parts I can be sinking my $$ into for this frame off rebuild. Thank you.

I've heard the Wiseco windowed piston is the hot ticket.  Plus 3hp on the dyno.  Getting ready to do the top end on my bike, I'm definately running with one.

Kaw rider,

Do you have any insight on the head mod discussed here on the board? Do you preform this type of machining? If so, what would you charge me if I shipped you my head? What would you charge for one of your heads and what needs to be done to the timing?

Thanks
-Maurice.

yes i can machine your head. Depends on what you use the motor for. My heads are machined different then the ones on here. I would play with the timong to see what you like.

Well, she was running rough at first. I found that the clip for the carb needle in the slide was bent to hell. The needle was sitting way lower than It should have been. A new clicp from ace hardware fixed that and shes running prime!

Nice! looks alot like how mine will turn out when done. Black plastics, but my frame is p. coated grey and silver hammertone.

If you can, get a 07 KX250f front fender, looks bad ass...

Nice and it will bolt right up or does it need modified? These are my old fenders I just hit them with black Fusion paint until I'm able to order the new plastics. The paint actually holds up suprisingly well and was a quick fix for this weekend's dune trip. Gotta get my 10 cup on tonight and get the kx250 ready.

It bolts right up, no mod needed. I was curious about the plastic paint, looks good!

It holds up well enough to work for the weekend. It DOES however take 7 days to FULLY cure.
It becomes increasingly more scratch resistant as it becomes bonded. It will work until I can order the new plastics and thanks for the info on the front fender, I've been wondering about that for awhile.

Kaw rider,
             If I work out the size shape and location, would you be able to do a windowed piston for the early barreled motors? I dont think the above piston would work too well as the early type has a bridge in the middle of the inlet port which extends down the middle and stops short of meeting the barrel at the bottom of the port.Not only would this possibly cause problems due to hangin up on the 'nub', but it would obstruct gas flow thru the window, reducing effectiveness. Was thinking 2 vertical rectangle shapes either side of the bridge nub. Your thoughts appreciated.K.
