Upshotknothole Posted October 28, 2021 Posted October 28, 2021 Breaking down a couple of GSXRs and trying to decide what to do with the parts. One engine is going to go into a 750 because I want a second 7/11, and 750 exhausts are impossible to find anymore. I already have a naked 7/11, but I'm kinda enjoying riding bikes with full fairings again. The other engine is eventually going to get the boost treatment. I've got an 1127 GSXR engine, a stock blandit 1200 engine, and a spare dot head that I wouldn't mind swapping onto either of them. Whichever one goes into the 750 frame will also be getting a set of RS38s and a full yosh system for a blandit. Kinda tempted to stick the 1100 in the 750 and save the blandit for the boost engine, but which one will be more work in the long run and which one will be cheaper for the biggest smiles when I do build a turbo bike? I'll post up some photos when I go out to the garage later and might actually do a build thread for this one. This was the bike before I took it on about a 1500 mile road trip and a mate rear ended me and broke my exhaust. 3 Quote
wraith Posted October 28, 2021 Posted October 28, 2021 (edited) Can't say about a boosted motor but I have a gsx1100f with gsxr750 38mm carbs and a b12 motor with a ported DOT head and gsxr750 38mm carbs and gsxr cams. Both are great fun but the b12 motor seems to have more fun grunt and just keeps going and going, on the other hand the gsx1100f motor, I can't keep the front wheel on the floor in 1st and 2nd and even 3rd can get light Ps. the cams in the gsx1100f motor are the same part number as the gsxr1127k cams That bit for info Edited October 28, 2021 by wraith Add a bit 1 Quote
Joseph Posted October 28, 2021 Posted October 28, 2021 I was under the impression that the gsxf11 cams were the same as 1052 cams ? Quote

So I was curious and checked the part numbers. The gsxf1100 intake cams were used in everything from the gsxf600s, to gsxr750s, to gsxr1100s. The exhaust cams were only used in the following bikes.

I also don’t have a gsxf1100 engine and don’t see myself getting one any time soon. Quote
Upshotknothole Posted October 29, 2021 Author Posted October 29, 2021 Tried fitting my 1200 exhaust tonight. Does not like the fit on a 750. Definitely time for a bigger engine. Couldn’t even get the header on without removing the oil cooler from the mounts. Looked at my 7/11 that has an akro 1200 exhaust and it looks like with a straight oil cooler and spacers for the lower mounts, it’ll clear. 2 Quote
fatblokeonbandit Posted October 29, 2021 Posted October 29, 2021 Just need to say, I had one that colour back in 1992, uk was water cooled not oil cooled like you lot over the pond.. It’s the best colour scheme for a slingshot ever I know one or two members might not agree, but I’m right 1 Quote

Dezza Posted October 29, 2021 Posted October 29, 2021 Don't Hindle still make oil-cooled 750 exhausts? Alternatively, is there anywhere in US/Canada that will make you a bespoke system at a reasonable price? Quote

Hindle sells exhausts for slabbies and 88-89 slingshots, but I've gone back and forth with them for 90-92 and until they can get a bike in to test fit the exhaust, they won't sell them. Really want to just tell them to make the down pipes 1/2" longer and keep everything else the same and we'll make them work. Yosh America wants $450US for a custom can, probably looking at over a grand for a full exhaust from anyone that knows what they're doing anymore. Pretty sure the UK has way more slingshot stuff floating around than we do. All of our bikes got totaled or are sitting in the garages of collectors now. 2 Quote

Shame: there are multiple places that will make a bespoke system for less than the cost of a fancy branded can in the UK. We are lucky here 1 Quote
