Suzuki GR650 - back to work...

Re: Suzuki GR650- accidental GP syle exhaust........

Bummer Rich! The other good news is you were with friends and not out alone left to fend for yourself. The old safety in numbers thing.

It felt like it was running rich and the plugs were black so I tried adjusting the needles and pulling some discs from the Supertrapp muffler.

Also sounds like you figured out that is the wrong way to go. You want to add disks to lean it, removing discs not only increases your back pressure but enrichens the mixture... Easier said than done out on the road I know.
12 seems like a BUNCH, I doubt you will need that many. IIRC, Mine was restricted with 6, added 5 but then it was too "peaky" so I then then subtracted 2. Now it is running pretty good with a smoother powerband.
Each tune is different so yours will vary I am sure.
 
Re: Suzuki GR650- accidental GP syle exhaust........

You're absolutely correct Hoosier - I was just trying to go from one extreme to the other and didn't really think it thru......

I'm sure I won't use even close to all of them, but it will be nice to have the option. And besides, 4 of them did get chewed up a little so they could use replaced.
 
Re: Suzuki GR650- something big is brewing......

Wow.....it's been awhile......

So yeah - something big is in the works. Something REAL big:

More details as I get there......
 
Re: Suzuki GR650- something big is brewing......

Well isn't that a sexy red. More please.
 
Re: Suzuki GR650- something big is brewing......

yes,more please.That's the color red I wanted to paint the frame of my black bike.

1980 GS850 "G" (the touring model). Before I hammered in the knee dents it had a 5.9 gallon capacity - compared to my current 3.9 gallons. I'll post much better pics and more details later tonight.
 
Re: Suzuki GR650- something big is brewing......

I've got the same tank, I think. Were the sides easy to hammer in? I tried it with another tank and had a bit of trouble keeping the dents even on both sides.
 
Re: Suzuki GR650- something big is brewing......

It was pretty easy - a little too much so. I tried making them deeper and deeper, but it started pulling in the steel towards the front. So they are longer than what I wanted.
 
Re: Suzuki GR650- something big is brewing......

That's pretty awesome. Additional fuel capacity while keeping a it sexy = WIN.

Ok, here's a comparison of a GS450 E/S tank to the GS850G tank:

Yes, it really is THAT much larger.......Now, mind you the stock petcock is hitting the frame in these pics, so the 850 tank is MUCH higher than it will be with a Pingel petcock......about 3" higher. With a Pingel, it lowers the tank so that it is just about horizontal with the ground. But hopefully this sheds an idea of where I'm headed:

Re: Suzuki GR650- something big is brewing......

That looks good. With that seat and cowl on there it looks a little bit like a Thruxton.
 
Re: Suzuki GR650- something big is brewing......

Holy bejesus! I like that tank. Talk about a range increase.
 
Re: Suzuki GR650- something big is brewing......

I too dig the bigger tank.Now you can ride around the block a few times instead of once without refueling. ;D
 
Re: Suzuki GR650- something big is brewing......

Wow Rich, that'll be a great looking setup when it's done! I agree with John as well, it does throw out a little Thruxton vibe
