How much horsepower can spoked wheels take before they blow apart
 
Going to go check out a '91 GSXR 1100 parts bike in southwestern Colorado this weekend. It's got an 1127cc, 145 HP stock oilcooled motor for the proposed engine swap. Seller says the motor started up and ran great with a push of the button - no excessive noise, no smoke, no rattles, no leaks. Also said all the gaskets look tight, head, valve, base, exhaust.

We'll see.

Needs a bit of work - a new battery, new engine covers, and some of the engine fins are bent/broken from the bike being dropped.

Small price to pay for big HP. :D

Those Gixxer 1100 motors make a lot of power and look good in a GS1000 frame (see signature pic), so I'm excited.

The whole donor bike in the picture below minus the plastics is going for a good price ($850).

Dammit (sort of). ](*,) ;)

Seller on the phone tells me that the compression is only 120 PSI across the board on the cylinders for the Gixxer 1127 engine. Should be between 170 and 200 PSI for this motor.

Lemons into lemonade time, maybe. An overbore rebuild with new pistons and rings would take us out to 1216 cc, and a ~155 HP GS 1216 S might be a wee bit fast, and it still wouldn't break the bank because of the low initial cost of the donor bike/engine. And these oilcooled Gixxer 1127 motors are pretty much bulletproof like the GS motors, and impossible to find to boot. About the only way I could get the GS1000 motor to post these kind of numbers would be with a complete full-out rebuild and a turbo/nitrous setup, which would probably be very expensive, decrease engine life, make the engine less reliable. And the GS 7/11 project (83-85 GS750 body, GS1085 motor) is now brewing on the back burner. Decisions, decisions.

What do you think?

I dunno man. 850 bucks for an engine that needs a rebuild, and a frame you'll probably put in the scrap heap? Its your money, but if it were me, I'd look on ebay a bit longer, and see if something turned up. If your going to rebuild, why don't you keep the original motor, install a big bore kit, and an oil cooler? At least then you won't have to dink around getting your chain alignment right, and fab motor mounts. Just my 0.02 cents. The oil cooled gixxer motor does look cool in your new pic tho.

"I bought this bike about a year ago from an obviously talented guy in Florida. It started as '78 GS1000.
Some of the mods include, Raask rearsets, Dyna coils and ignition, Earls oil cooler, GSXR 1100 forks, GSXR 1100 wheels, custom braced swingarm and Works shocks that are being rebuilt. The engine is a GS1150 with a 1229 kit, Falicon, Carillo, 36mm carbs. It is quick! Loads of fun, 2nd gear power wheelies and lots of attention on cruise night."

It has to be your computer or settings, not sure, all I know is the pics have always been visible for me ever since they were first posted. I am using Firefox as a browser, not sure if that makes a difference.

Fixed for the Internet Explorer users. It was working in Firefox but not in Internet Explorer.
 
Thanks again PJ for posting the pics.
The Works piggybacks are ready, new tires and a top end oiler are next.
Come on spring!
 
Had a look at that GSXR 1100 motor over the weekend in southwestern Colorado. Sad to say, but pretty much everything that could be wrong with it was - low compression(130 PSI, should be 170-200), fouling the plugs, BIG flaming backfires at about 4000 RPM on up, broken engine fins from being dropped, blowing lots of smoke, leaking gaskets etc etc. Would need a serious top to bottom rebuild. So that plan has been laid to rest. And the project takes another turn. ;) :lol:

Next (and maybe should have been the first :lol:) option is to rebuild the GS1000 motor with a 1085 Wiseco kit, K&N pods, Dyna S ignition, Dynojet stage 3 carb kit, weld the crank, undercut the tranny, and install an oil cooler. More engine mods would then follow down the road.

Had a chance to drive through Arches National Park near Moab in southeastern Utah on the way back home to SLC from Colorado. The park is famous for its rock formations that have formed over the eons.
Here's some photos we took: http://www.slcelectronics.com/GS1000_Build/Moab/index.htm
 
Arches is just bueatiful and so are your plans for the bike. To bad on the newwer GSXR oil cooled motor. At least you have an engine already. Next time your going to be in SW colorado (in warmer weather) send me a PM and we can go for a cruise. :-D

YJ-

Welcome to the GSR!

It's me, PJ. Hadn't seen that picture of your Yoshi special - nice!!! Are the numberplates new?
Click to expand...


Hey PJ,

Been on here before but forgot me password doh :shock:

The number boards were on for a while and I liked them but others weren't too keen so I took them off.
They will be on again this year!!!!
The motor has also changed for a slight upgrade.
Stage 2 dialled in cams and a 1085 wiseco big bore. It won't frighten the modern stuff unless they get too close to the pipe ha ha

YJ
