BEC exhaust questions
Guys, its been 18 months since i could jastifiably start a topic in the BEC section, I'm glad to say that I am back on the build again and
thankfully i have managed to skirt around the edge of the CEC section, although i may well have dipped a toe in the water to see what its all
about!
I have bought Taz's part built project from him and am starting to plan out which way i take the build.
Im estimating some costings etc (dont worry i have built before so i know the "add on 25% to your already wildly over estimated figures"
rule!)
One thing im concerned about is the exhaust, Its a GSX-R 1100 and im right in thinking its not the most commonly used engine???????
Therefore im looking for advice on places and if possible any rough prices from experience on getting an exhaust made.
Does anyone know iif it has the same flange pattern as some other comomon suzuki engines? Hayabusa? GSXR1000?
I am casting my mind back now but didnt calvinX use a suzuki engine and he had the exhaust exiting toward the front in an odd fashion?
What engine did he use and anyone see his exhaust and how it was made?
Oh and i will also be looking for a set of SGX-R 1100 carbs, any bright ideas?
Any advice / experiences welcomed
Thanks

Calvin had a GXSR 1000 I think it was. He made the exhaust himself, I remember him posting pictures of his welding. He had it in the usual style at
first until he failed at SVA then he redid it so that the CAT was inside the bonnet and the exhaust exited flush with the side panel. Queue dirty
black patch down the side of it.

I would recommend making your own.
Tig welder from machine mart and stainless steel dairy bends will do the trick. Will cost a lot less and you will then have a Tig for free.
Alternatively you could see Martin Keenan.

GSXR1100
is it air or water cooled?
They differ in a number of ways including the spacing of the cylinders (quite important that).
I know a fair amount about water cooled, so this all applies to that, but it may be relevant for air-cooled.
sprocketadapter.co.uk or whatever they are called can supply a propshaft flange adaptor for you (£60). no problems there just tell them what
engine!
I got mine manifold from Exhaust By Design (local to me, £425) and used a MK silencer (£150). Anyone who does custom manifolds can do it.
S&S in the USA can supply a manifold at a good price, but its difficult to know whether it will fit!
I have a bike manifold from a WP model that I used temporarily (£50 from e-bay) but don't need anymore. I don't know whether the manifold
flanges are interesting, as you can measure the hole spacing for the bolts, and the hole down the middle is going to depend on your pipes.
Water cooled needs a bit of work on the hydraulic clutch (it clashes a bit with prop), there is a posting on here for that already, a few solutions
out there (I think air cooled has a cable clutch). Now rocket science, but a bit of a bother.
Regarding carbs. About £80 on the bay of e, but budget for some pain. Water and air cooled are different.
I am struggling to get mine through emissions, and Cloudy also struggled. Basically the 40mm carbs are big which means getting a clean idle is
challenging.
oldskool suzuki isn't a bad resource for some of this stuff.
have fun

oh that Taz (there are two).
Yes that is water cooled.
Drop me a U2U if you want.
