GS1000G vs GS850

[Havoc]

Afternoon all. I have a question. Been looking for a 1000G motor for sometime with no success. Think they've all been triked. How different is the 850 bottom end to the 1000? 850 motors appear to be a lot easier to source.

Very, looked at doing it myself years ago but the 1000 top end will not fit the 850 bottom.

Also the gs1000g shaft (where it has the 4 bolt holes are) are a different size to the 850. 

[johnr]

and if youre going to fit something that isnt supposed to be there, i bet there are still plenty of gsx1100g  motors about (shaft drive gsxr motor)

[wraith]

Or keep a eye open for the gs1100g

I've found a GS1100G but the fella wants £800 for it, too rich for me even if it's a minter

[wraith]

There was a gs1000g bottom end on flybay and put a 1000 top end on it.

There still is, it's minus transfer box bevel gears and apparently the clutches are different. Every other bit is compatible though. Might still take a trip over to Wisbech and pick it up, just wait  for the other bits to turn up. Spoke to Nick about it at the weekend. He's the source of the £800 1100G donk as well

Anymore info on the 1100G pm me if your not interested in it

Yes clutch is different to the chain drive, the crank is also different.

The gs1000 chain drive top end (complete) will fit straight on the 1000g bottom end, the gs750/850/1000 cams all interchange, you can used ever the GS CV head or slide carb head.

The geny cover on the g is different to the chain I think but you can used the gs1000g or chain drive geny and starter clutch or the gs850 one.

theres a gsx1100g on Eblag now for 500 quid, you could probably buy it and keep the motor loom and carbs and sell the rest back on to recoup some money, ebalg listing number ,

Seems to have gone

I had a gs850gt trike which i put a gs1000g motor in. The 4 bolt drive flange was bigger on the 1000 but the splines were the same so just swapped to suit. The starter , alternator and cover all swapped over from the 850 as well. Then i used the 850 CV carbs on the 1000 by cutting the rack in the middle and welding in a little bit. Then stage 3 dynojet kit and k&n's had it running strong again. Couldn't believe the difference in power and torque between the 1000 and the 850. Massive gain. Dont know about going the other way.

I like the idea of an oil cooled gsx1100g motor in an aircooled frame. Reckon that would look wicked and go hard.

Guess that's me off to Oilcooled now. Probably going to use the front end and back wheel as well. With the carbs and electrics all on this it will cut out a load of hassle. The model is rare enough here for the wheels not to be recognised and look a bit exotic 

[slingy1157]

F#@k Yeah.  That was easy. I did try to find a GSX1100G motor for my trike at the time but couldn't find one, then the GS1000g motor turned up so settled for that. 

Going to be an interesting build for sure.

[Captain Chaos]

it would probably be easier to just put the GS bodywork on the GSX.

But Havoc does not do easy. Thank f*ck.

[Captain Chaos]

and Tom you swapped the front brake discs around yet? Better do it or Suzanne will find out about this bike. And other things.

As soon as I get in this evening, forgot. She's at work until midnight so job's a good 'un   

[wraith]

Should be cool, the rear wheel gos strate on the GS hub, had one on my shafty about 15 years ago

[slingy1157]

Monoshock using the gsx rear? or just fit the wheel and do an oldskool style underbrace on the gs arm with some piggyback style rear shocks?

[Havoc]

Twin shock. The arm is going to need some work to take the wider wheel. It will most likely end up a mix of the GS and the GSX arm and some extra bits of steel.

on the old site wraith did a gs1000g build using a single side rear wheel and swingarm from a revere fitted to the gs frame, looked cool as fuck!

And I still have the bike, but I have put the standard bodywork back on.
