From what I understand from racing cars all my life (sprint cars now) is that a hypereutectic piston isnt a true cast piston. They are in between a cast and a forged. In a lower class car I used to race we were breaking cast pistons and tryed a hypereutectic and had good luck with them. I'm not...

I'm just trying to help the guy. No pistons are indistructable but if anyone is gonna argue that cast is as good or better than forged I disagree. Sure a cast piston will work for a while and will be cheaper but all high end engines from 8 cylinders to 1 run forged pistons. There is'nt a engine...

You have to get head machined for a 240. One of many things that is needed in a head is to have the squish band be correct. Squish band has nothing to do with the head gasket, it has to do with how the air/fuel mixture reacts in the combustion chamber under compression. If it's wrong you will...

Well... if it was me I would have him weld one up for that good price. 2" extension is good but 3" is better. At least that's what she said, lol. Anyway, if he can fabricate a 3" extension, you will feel a differance. I dont know if ur blaster is any wider than stock but you can widen a couple...

That sounds like a great charity. I'll keep them in mind. ',m completely broke right now but maybe in future.

Do some research on quality and price. I dont wanna baby my bike because parts might break, I wanna rip it with no worries. Price is always a issue with me though. If you feel it's to short for you then I would approve of the extension. I have a 4" extended swingarm (not a kit) and I love it. I...

I had spark and fuel after a top and bottom rebuild and I probably kicked engine over 200 times before it stayed running. It would stumble and fart but not stay running. I pored gas in carb also with little results. Then, like magic she fired and purred like a kitten. I still dont really know...

I thought I saw a youtube video on how to pull a flywheel without a puller. I could be wrong but I thought I did.

No kidding. You come here for help then talk sh!t. If all you got from here was change the oil then go somewhere else. There is alot of great info on this forum you just have to look. If 2nd is locking up then I'd forget about what first is doing and split the cases. Something majorly bad is...

I'll check pipe. I'll be sick if I get sand out of it. I probably have 10hrs (and a couple bores) on it sence I sand blasted it. I would think it would have blown out by now but maybe not. I'm thinking if it was sucking sand that it would scratch stuff fairly consistantly. I"m getting more of a...

Hey Ken, good to hear from u again. You raise a good point. I repacked once and it looked wet. I hav'nt repacked many silencers so I did'nt really know what to look for. I also sand blasted and painted the pipe because it looked like crap. I did clean the inside of pipe but to be honest, not...

Ya, I luv riding dunes. I gotta drive 3 hrs to get to them but it's on the pacific coast so the view, weather and riding is awsome.

I would run a leak test to see if maybe a leake caused it. Do'nt do the top end and not check anything else. It might have been fine for along time but something failed and it cooked ur piston recently.

Cool, I'll address the plug issue a.s.a.p. I wanted to tell you that the member heatlbj6 that just posted a pic of his piston and you replyed. My damn piston looks something like that after one day riding. Ya, I have issues.

I'm hauling ass or parked. That's how I do it. I wonder if I had a air leak that is causing a lean condition, would it show up on the plug or could it be rich looking and still causing a overly hot piston condition?

Well, I again forgot what the comp. is after all this time. Ken Oconnor did my head and it was pretty high for pump gas but very runable. I think in the 150ish range. I agree, a plug with a crush washer should seal when thightened slightly. Im gonna look into that plug mating surface. I think...

I just remembered this, The spark plug will get oil around it sometimes. I have tightened it to the point of almost stripping it and it stops but I feel you dont have to tighten a spark plug that tight.That could be the problem.That has always bothered me alittle. I might have a problem there.

Oh ya, now were getting deep. Ok, airleak only when running? Do u have examples because idk. The cases were not lapped. I split cases and reassembled before I learned that it is something done often and might be needed. No leakes there with leakdown. squirted everthing with soapy water along...

Do you think that pipe could cause a increase in piston temp? I'm still searching for something that could cause the 4 corner seize scratches. I got some good ideas from all you guys. Maybe I gotta change my break-in and pre ride procedures. It sucks to have a dozen different ways to do all that...

Do you nkow anything about it. I think I sill have pictures, I'll look. I'd like to know forsure. It does have a slightly different shape that any FMF I've seen latley.
