7/11 slabside in the making.

[Hellraiser6662]

Hello i used to be a member a few years ago when i got into my slabsides, where i ended up with having 4 slabsides, and a rat cafe racer slingshot. 

So over the years ive been getting one together out of all the others with full fairing and have it a little special, ie upsidedowners rear shock wheels the usual mods, but heres the thing i tattooed a friends wife for a gsxr1100 slabside so i can put the motor into my 750 slabside frame, so could people point to the treads where it has been done before, so i can get to know what needs to be done.. ive strip out the 11 now its time to strip out the 750 that ive just got back together. 

Heres a few pics 1st is the 1100 the next is my daily hack gsxr750 sling, the last pic is the mess my workshop is..

It's really just nuts and bolts, on the slabbies.  The 750 cdi has a higher rev limit than the 1100, the ignition curves aren't much different.  Use the 750 engine mounting hardware.

The most awkward part is getting the fuel tap sorted. A 750 fuel tap will just fit, you may have to lift the back of the tank with some washers to get clearance. But the 750 tap doesn't flow enough for the 1100 in my experience, and the 1100 tap may not fit the 750 tank depending on what year bikes you have.

Love the slingy, you must weigh about 4 stone looking at the subframe.

Isnt the rear lower engine bolt a different size too? Either drill the frame holes larger or sleeve the motor down. Stops the mounts cracking.

It could be slingshots that this was different on not slabbys mind

I think the 1052 motors are 10mm bolts, the 1127 slingshots are defo 12mm as you say.

1052 bottom back engine mount is 12mm. Easiest thing to do is drill the bottom back engine mount out to 12mm on the frame  and fit a 12mm bolt. Use the 750 engine brackets & I take the sump & cam cover of to get the 1100 engine into the frame, it's quite tight.

Cool thanks for that.. so can i keep the wiring loom inplace on the 750? And just replace the cdi with the 1100 one? Heres a pic of the 750 slabby that the engine is going into.. the bottem pic is of another slabby ive got and is in the middle of a cafe racer make over, all the bits came off the bike that had the upside downers plus it has the wheels off a 1st slingshot with a r1 rear shock. The story and bikes ive got is mentle one, all bought to make one slabby look cool which was bought over 14 years ago after missing a bike on here that i didnt buy with everything done to it....  haha

Yes swap the cdi over.

Cool thanks that makes life easier.. now for the heavy lifting and shoe horning it in the frame.. 

Also do the swing arms swop? I heard the 1100 swinging link is better than having the 750 one?

Put the engine on its side then place frame over it. Here’s my home built 7/11
