BIKE TALK / Re: Fresh 5k $ rebuild= 1000ft and BOOM
« Last post by Rocketgeezer on March 25, 2017, 06:25:57 PM »
The leakdown was 4% across all (according to the shop)? Could this still be the case? If so, how does a valve shim get thrown (I don't know)?
They put air in the cly it leaked, but they could not tell where, BS on that for one, also no way its going to have 4% across and one cly that cannot hold air, and I don't buy can't see nothing on the scope or they did and not known what there looking at, and as John said it could be a throw shim which could be caused by a jackass setting up the head and getting clearance wrong, or possibly severe valve float, from weak springs or a combination of the weak springs and the jackass, and I understand what you meant by the 20HP, but 20HP on a turbo bike running 18 psi boost ain't nothing, should not have effected jack, you said nothing on your original tune up was changed, the rebuild basically was freshen up what you had??? compression, cams, injectors, or anything in fuel system or ign system was not changed, and bike ran fine until it got revved up good when you made the pass???, if the scope check really was OK the thrown shim could be a possibility, that the shim or a part of it has a valve slightly jammed and holding it open a bit, you may or may not see this on a scope check but you would sure as hell see it when blowing air in the cly, it would ether leak out the throttle body (intake), or exhaust, tell Steve you need to know what exactly caused this cause you got a forum full of guys that need to know, also if you need them I have a spare head and a cherry stock bore cly,

If the piston is moving and there I nothing viewable on the scope, it might just have thrown a valve shim.

Thanks for the reply and effort Rocketgeezer. They were blowing air into the cylinder but I could not see the gauge. They said the needle would rise but not hold. They scoped it and saw nothing inside. My guess is broken rings like you said or maybe a head gasket. Probably not a head gasket though. The piston looked good and was moving.
 There are other issues I noticed along the way with this particular place and this process. In any event, it's on its way to Knecum Tuesday.
 The 20 horsepower part I was referring to is the maximum horsepower I estimate it made before it fell apart. It's running the same map it ran when taken apart, which is a map that worked great for 25000 miles for 18lbs on pump and 20 something on race, but I never ran race fuel or went over 18lbs.
 I'm going to have the injectors checked and cleaned too. Three plugs were souty and one (#2) was too clean. Makes me wonder if a lean melt down or lean inbuced head gasket failure can occur at 2k rpm and no boost? My guess is that it was fine until the failure kno running issue oresented) then it failed, the the 3 good cylinders got too much fuel.

NITROUS / Re: 2 Staged Fuel Pressure Regulators?
« Last post by Rocketgeezer on March 25, 2017, 01:01:04 PM »
you could use an air regulator to put pressure to the fuel regulator. use the nitrous to do it. Tee the line to the jet, regulate it to a set psi, like say 30 and apply that to the fuel reg when the nitrous is on. fuel pressure goes up when nitrous is used.
This could work, but keep in mind when your FMU is operating at normal idle pres 40psi and when is get boost pres it go's up depending on the FMUs rate of gain, on a typical turbo application its like 6 to 1 so even 10 lbs to the FMU set up that way would give you 100 psi of pres, way to much, you need to get with a bike nitrous pro someone well experienced on running bikes on nitrous especially a dry system, if I were still playing with nitrous anymore I would look to Ryan Shinitz, as far as I know he's gone faster with nitrous than anybody else, and could most likely give you a set up that will work, and stay together

John, I just did some checking on Everett, with the BBT, and just king of poked around to see if there were any consumer complaints, could not find nothing, they have a BBT A+ but no reports, so ether there good or nobody bitches, but I'm inclined to think nobody bitches, my experience has found the only time you get anything good out of a dealership is if you know one of the guys in the  back he takes care of you, without the front knowing about it, now don't think for a minute that I'm defending those people, but there really is no shop that would guaranty a race motor, but from a business standpoint, the least they could do is offer to fix it for cost of parts, what the bitch is they don't seem to care, they got your money, so what if you bitch to everybody and there brother, Everett don't care, especially if there busy, all that being said, if it were me in your situation I would bring it to Knecum to,  good luck, and please get back with what you find,

#50 & #51 need to be reversed, which will also put Ransom in the top 50.

Scott:

Will correct that
