Gen 1 grudge bike build.

[Bigboy Busa2]

My replacement frame came today. I was going to post pictures of the build as it happens. Maybe somebody will be amused.

 

[rubbersidedown]

Yup,thats a frame. When will it be finished?
Rubb.

 

[BigBSBusa]

It's a start.

 

[Bigboy Busa2]

Cut tabs and cut rail. And a few rounds of grinding. Going to check tail to make sure of the height and smooth all the grinds. I slipped on the grinder a few times as expected. My plan is to assemble and run the bike for the rest of the year. This winter to have the frame powercoat. And motorwork.hopefully decide on a color for the frame

 

[Bigboy Busa2]

Smoothed out the grinds and some more body fitting. Pretty satisfied for now. I have some more work on the body that I'll work on later.

 

[Bigboy Busa2]

What would cause the exhaust valves to be "cleaner" on only 1 cylinder. And the pistons to be greasy? Thanks

 

[Kevin Jones]

Looks like the map was rich. What did the wideband read normally? If i recall stock flash has cylinder offsets for fueling, the outside cylinders were either richer or leaner? Most of the time I run mine around 12.9 to keep them cool, stuffs going to look like that. Nothing to be overly concerned with. You are going to get the valve seats cut and new seals/springs right?

I will later. I have not dealt with the a/f. But it will be a wego 3 that I have. Head gasket be here by this weekend. And about 54 h.p. nitrous on this stock head. But yes head will be done later. Am going to put 64# springs on now. Thats why I too head off

Hi. who makes the springs? I bought my springs from DME the are made by Pac Springs Co.

These came from ape. Not sure if their made in house. But a most of their stuff is

If you show us a picture of the top and bottom of the head gasket, those OEM style gaskets usually indicate if there was an issue however you said a compression test came out ok? Did you attempt a leakdown? Ive seen insufficient valve lash in the intakes cause a cylinder to be lean so you may want to pop the cams back in with the head on a stand and check the lash. In extreme cases the buckets will be worn at the contact points for the lobes. I would want to identify something before i put spray to it as well as sending your injex off to get cleaned, prolly to Scott Horner or MPS or someone. I am OCD and things like that roll in the back of my head at all times, it may not bother you.

 

[Kevin Jones]

Also i would pop on a new set of viton seals for as little as they cost while you have the valves out for the spring install.

I had this head for a long time now I got a deal on. Maybe use it. What you think of that "jell" on the intake ports? Cut guides and milled.

 

[Bigboy Busa2]

This is leakdown on that same motor. I believe. And check out the compression. Funny how I left out #1 huh. The one in question

 

[Kevin Jones]

That is good leakdown #s. That is epoxy in the intake, people use it for some specific cyl head applications. I don't know flow characteristics enough to say what works and what doesn't however i know it is widely used on kawi heads to good effect. I had a circle track car busa head that had an epoxy job to enhance torque in a specific rpm range which the car (lightning sprint?) stayed at for most of the race. I still have that head but haven't done anything with it.

 

[Bigboy Busa2]

Putting can holder. It was hot, I am tired and these mosquitoes are making me dance. Didnt pay attention to tension and pop. Cam can unseated. Great lesson. I have done this before. But will check 16 times next go round.

 

[Bigboy Busa2]

I bought this also. Have blead a lot of different ways and wanted to try this. The old fashion wat works best for me. And this seems like alot less mess. Has a rubber ring in socket to seal off fluid and handle slides up and down to let handle swing without taking socket off nipple

 

[Kevin Jones]

I like to try that bleeder tool. Don't think you are the first to break a bearing. The clips are sometimes very sharp and get dug into the groove, I guess that's why gen 2s are reversed. I don't know. Ive broken them. Total PITA. Usually happens when I try to ziptie the cams to the chain and finesse that bitch in there. Feels good but that gut sinking crack when you tighten down the bolts... Make sure you 89in lb those too.

 

[Kevin Jones]

I don't think that head gasket was an issue at least to my eyes.
