Yup, I was right, I'm too lazy to attempt that!

I'd like to see that. I'm too lazy to try it, but would like to see it!

I'm running your top end oil cooler to help out.

Good point I hadn't considered on the head gasket blowing! Just looking to raise the compression slightly over the off the shelf JE pistons to be closer to the CR run on the 70's racers. Probably ov ...

Now just have to decide on head gasket thickness, thinking a copper 0.032" will workout.

Too much and this motor can go ballistic, but I'm not aiming too high. The new pistons I just got claim 10-1/2:1, but the Yamaha factory tuners ran this motor at 11-1/2:1. I just thought I check int ...

I sure hope so. This was a long term project to take the bike as far as I could and it will be show time this spring when I finish the final motor work. I head back to work in the morning, so will b ...

Way cool program, will have to measure some volumes first though, but cool.

Santa is bringing me a set of JE 77mm pistons and I'd like to use a thinner, copper head gasket to raise the compression ratio from the 10-1/2:1 these pistons give, to about 11:1. Anybody done this ...

Got my head all ready to install, just need to add the valve springs. Anyone have an alternate technique that doesn't require me to order the spring compressor from Mike's that I forgot to buy earlie ...

New valves and guides in, guides honed, but forgot to order Mike's valve spring tool so I could finish it off - crap. Waiting on the mail now..... Santa brought the JE 77mm pistons, almost ready for ...

Ported head is in the shop to get the new guides honed to fit the SS valves, and Santa is bringing me a set of JE 700cc pistons. Need to send the cam to Megacycle for grinding soon. Hope to tear dow ...

No change to the motor location or mounts. The forward tilt in the picture is a combination of raising the rear by changing the shock mounting position and having the forks compressed by the tie-down ...

Thanks guys, that's what I thought, but wanted to be sure before I went at it. Luckily, I have a good race shop close that can get the machining done for me.

I just bought a new set of kibblewhite bronze valve guides and Mike's XS stainless steel valves and they don't seem to fit. I measured them both at 8mm, so no real clearance to go together. Does an ...

I've been tinkering on this one for 2-1/2 years, a little at a time. I've saved a bundle shopping on eBay, but still, I'm $6k into this beast so far.

I'm just afraid I'll wad it at the track, no w ...

Thanks, but really it was way easier than most think. It helps that my folks had a Yamaha shop in the 70' - 80's.

Yup, what he said, brake check valve. Works great and very cheap.

Yes you can, use spokes for an XS 360. You'll have to use a drill to "adjust" the angle of the spoke holes slightly, but no big deal. Be careful when you dish the wheel when you relace it and you wi ...

Yes, yes, and MMM.

I relaced the rear using the stock rim and spokes, just to freshen it up. The front has an 18" rear rim on it, using spokes from an XS 360, I had to drill the hole angles slig ...

Not many original parts remain!
