Picked this up from the the guy I got the RF from. 87 GSXR1100, tatty but all there, stock exhaust (rare), solo seat, tank is iffy. I hurt my back sitting on it in the shop, LOL.

  Ok this one has my attention. Uncomfortable? Yes, no apology. All business oil cooled monster engine. This is a time machine of the early Japanese true early Superbike . Well done!!!

It is a tight fit. I think it would be a 20 minute ride for me with my height of 6' 3" and 6 knee operations. 800$ for this one too, cheap at twice the price.

Nice .

  I spent 2 hrs on an RC30 Saturday, with destroyed knees. Inspirational legend Sportbikes are worth the ‘discomfort’.

Groovy!

Got the "redneck" tumbler out of retirement to help rattle some flaky crap out of the replacement tank I picked up. I had it in a vertical position first then made the wood platform to get a different abrasive action. I have been using drywall screws and  slingshot ammo inside.

Evaporust is your friend.   ;D

Awesome bikes. Tough as nails. I have a “ from new” 1986 GSXR1100. I actually found it fairly comfy. Riding one in traffic on a hot day is a bit of a bitch with lots of radiant heat. A great motor even by today’s standards. Handles great on tight, bumpy and sometimes dirty back roads. On a “good air day” it will easily lift the front wheel in second.  I bought it to replace a VF1000 Honda which was top heavy and handled like crap thx to the 16 inch front . Riding the Honda fast was like “dancing with a fat girl in high heels” .  It could be done but you had to pay attention. The Suzuki was a big upgrade. If you get a chance to buy a good one do it!

On the rust remover topic.....apple cider vinegar works wonderfully to remove rust inside a tank.  Rinse out quickly with water and baking soda once done.

You still have the bike? Blue/wht or Red. ?

Picked up 3 litres of reg vinegar. Will try that first. Many people have opinions on POR15 or Kreem?

I used the POR15 Motorcycle tank kit on a severely rusted 900F tank.  Everything needed to clean, strip out the rust, and coat the inside of the tank.  That was more than 20 years ago and the liner is still holding up fine.

I've used Metal Rescue successfully.

yes. Red/blue

Not sure if regular vinegar works as well as the apple cider vinegar.  I've heard it doesn't but don't for sure.  The apple cider vinegar works. 

Cleaning vinegar would work better than normal stuff intended for chips.

Both regular and apple cider vinegar are composed of acetic acid, but apple cider vinegar also contains citric acid.  My guess is that it doesn't matter which one you choose to de-rust a tank but that's just a guess.  I've never used either, preferring to go with Metal Rescue.

I started on the GSXR1100. Built a bracket for the motor so it will be easier to clean/detail/valve adjust etc and am close to getting the chassis stripped.

i use caswell tank sealer $50 does two tanks. you don't need to clean the tank spotless this stuff covers over the leftover rust. used it on many tanks and all are doing great. just make sure you roll it around good and coat the whole inside.

Does that right side frame member actually unbolt to enable the engine removal? 

Thankfully, yes!

Some engineer had a better idea!

It has 3 connection points so I don't think much rigidity is lost either.

That usually happens.....the engineer has the best idea, but the designers and accountants make changes.

I have done about 5-6 tanks in the last 10 years, used both Caswells and POR15 Kit.

Caswells is very thick and good if you have pin holes to seal, if no holes use POR15.

POR15 is awesome, the motorcycle kit is available from Lordco,

To prevent the flash rusting that occurs after the final etching/cleaning rinse, use a liter or two of isopropyl alcohol, dump it in and then rinse and dry, it removes the water and aids in drying.

My last tank I did on the 1981 GS650E I used the isopropyl alcohol and it was perfect inside, it almost looked factory.

Good luck with that bike.

David.

Thanks for the tip. It does need to be coated.

I guess I'm "all in" now.

I will start putting this back together as parts arrive and I rebuild/restore stuff.

I have rebuilt the calipers with seals and dust seals and painted them. Kit also has new bleeders etc. I use my little electric oil heater with aluminum plate to help speed up the curing. Powder coat is done on the wheels, waiting for front wheel bearings and sprocket carrier bearing.

I installed the wheels and freshly serviced shock.

Got the motor back, what a bear..Trying not to scratch paint (partially successful) . Some guys have put 1100 motors in the 750 frame (7/11). Apparently you have to take the valve cover off and swear ALOT.

No thanks.

If you need any help....I can swear real good!!

Thanks but I just finished my Masters degree in swearing yesterday. Drop in if your in the neighborhood sometime Bill.

Got a bunch more of this bike put together, waiting on the carbs being ultrasonically cleaned.

I have most of the mechanical done, now to prep bodywork.

Motor.

Nice work!  Was that the original engine colour?  It's very plain.

Yes, factory RAL color.
