Gsx1100g 1991 1127cc upgrades ??

[Peterneedspower]

Hi all , I have just got a gsx1100g 1991 which has an oil cooled 1127cc engine….

I’ve upgraded to 4-1 viper exhaust

pod filters , stage 3 jets and shims..

3 ohm coils and leads

all good, but I’m looking for more power upgrades ..

can’t afford dyna2000

or turbo kit or nos or cams

here in the uk it’s expensive to add power..

many ideas would be really appreciated as if I knew if other models ie slingshot . I’d search market place for used parts..

hope this all made sence

stop eating so that'll save you money and you will be lighter so the bike will be faster

Well anything from the 1127s or 1157 will go in. Gsxr cams will give a bit more power at expense off bottom end. I'm not sure how much abuse the shaft will take tho.

Bigger carbs, like BST38s off the GSXR 750s or cams out of a GSXR 1100. Could even do a dot head swap off a 750 if there's enough room in the frame. Basically any of the standard upgrades used on the top ends of Bandits should work. Post up some photos, we like photos of bikes here.

Well, without digging deep into your pocket you've done the basics. 

As said above, the gsxr750 38mm carbs will give it a good boost but you will need the carb rubber inlet manifolds to match and they are next to impossible to find.

Gsxr cams will give you more top end power but again trying to get a good set theses days is not easy. 

So you're down to ported head and/or 1216cc big bore, never are in the cheep side.

Id say you are about maxxed out on what you can afford to "bolt on". Porting the head will yeild more power if you are competent enough to do so but its not easy, and not recomended to do yourself if you are not familiar with engine tuning
