No, Airfix models. Yeah, I know. :yup:

Still sticking to the plastic then

More like a sticking plaster if you know what I mean, keeps me busy & my head focussed. :sun: :yup:

I'm not interested in tuning the engine as in cams/porting etc as this engine is pretty well tuned for my needs anyway. Although I may have a look at the throttle body joints to the head & make sure these are well aligned with no lips or gaskets protruding. These were really shit on my Triumph 955i......

Good idea and simple to look at....many manufacturers tolerances with regard to joints and gaskets are a little sloppy....not saying Buell falls into this camp and looking at the bikes overall I still marvel at some of the detail. But probably worth looking at on a rainy afternoon ......
At work we have a visit from a firm oop north ( I'm from Essex, everything is norff to me) that specialise in 3D printing of auto parts for prototype and packaging proof and we have used them for JLR work recently. I'll check what they can do for you stack wise as it may cut your number of iterations. Ideally you want adjustable ones connected to an actuator but I ve heard your meccano skills are lacking... :D

That would be great Steve I can get you the exact measurements from the stacks that are fitted. I had one out to look at to get preliminary measurements to see if I could do them myself.
Unfortunately my lathe can't manage that width without the jaws fouling the bed as it's only a Myford ML10 & stretching to work over 50mm diameter. So kind of bolloxed there as well. Another complication is I found out that my throttle bodies are 64mm by the look of things, I thought they were meant to be 61mm?

I did find some 1190Rs stacks in the USA, £41 each but £26 shipping & a shitload of import tax & the seller won't answer any questions about the size of the fitment to the bodies or aperture size or whether the tax is doubled & shipping doubled for two. Probably cause I'm in the UK or he just can't be arsed.

Looks like I'm standing still till I can work something out, although at least I've learned a bit more about my bike in the process, Bonus.
Meccano was shit, five minutes to boredom for me.
All the best Steve.

Hi Steve,
The guy in the USA has gotten back to me, the 1190RS ones will fit. Just trying to work out postage & bloody Tax costs. Interestingly the actual mouth of the stack is 10mm narrower than standard, guess that's about speeding up the air intake flow.
Looks like I'm back on track. :dance: :yup:

F**k, F**k, F**k, F*****y, F**k.

The stacks from the USA fall into Ebay's global shipping programme & tax bracket, anyone who's ever dealt with this will know the costs are just extortionate. So that's That I guess. :headbang:

I'll have to work out a way of making some again. Bollocks. :headbang:

You know what folks, if I didn't love this Buell so much I'd get rid of it tomorrow they're so frustrating. :evil: :headbang:

Flippin KTMs & Aprilias are looking very attractive again at the moment. :sad1:

Hi Folks,
I'm a bit more upbeat again as I thought I was in a worse position than I was. Just the thing with the USA, disappointment I guess. :sad1:
I have a friend who has a CNC milling machine, I may just ask him if he wants a project & pay him for his time, He can work CAD really well but it's a pile of time for him & he runs a couple of his own businesses & is usually very busy. He may do them in his less busy times or his own time. May be able to get him to do an adjustable one depending on his interest. It'll be a lot more than the RS ones from the states as he'll do them out of billet I guess? He can take the measurement for the base from the original one which only leaves the trumpet length to work out how to do. Probably be in two pieces with the trumpet screwing into the base. Therein may lie the adjustment method if he can feather the sliding jointing edges so they don't disturb the air much. The base also allows for a much thicker alloy trumpet tube to help keep the air cooler, may even be able to fin the outside to help this, like i said depends how interested he is.
As I read somewhere today, (Yes I do read a lot when I'm interested same as most people I guess) He reckons "this in not about gaining air flow, it's about moving the power band" (I agree) He also quoted that "it wasn't about torque, but power". Not sure if I agree with that yet, they're the same to me right now, although I may be wrong.
So screw disappointment, I'm back on track and have a plan Phew :ill:
I'll speak to my friend tomorrow & see if he's interested enough to give it a go and get an idea of the cost. :sun:
Let you know how it goes. Thanks for the support folks appreciate it. :yup: Paul.

Yeah I guess Maz night be interested but think he's stopped reading this & probably has a bruised head from batting it on his keyboard already.
I think if I can get them done by CNC I will be in control of the design & mods as we go along, It's just a job for my friend, he is meticulous, so they will be spot on & I'll get to spend some time with him (poor F****r).
I'll then have the design to have him make some more then if anyone else wants any' as they'll fit other 1125r's & Cr's. He will have the design settings in Cad & that's what's gonna cost me the money, so all he will need if future will be the blocks of alloy set up press the button & it'll do them in much less time.
I'm gonna see what he's prepared to do tomorrow.
Wish me luck. Thanks for the reading though the dross I spout sometimes & for the suggestion Barney. All the best Paul.

Yeah, sorry Fimows should've quoted you, see the reply above. Thanks for reading & for the suggestions. Paul.

Sounds like you have a plan for adjustables....nice if it comes off. I'll be interested to see if it works out if your aim is to bring the power delivery lower down from where you reckon it is now. Nothing new under the sun as you alluded to earlier (I can remember mates fitting numerous bellmouths to try the same thing on their triumphs,BSA's in our teens....not me ,I had a two stroke Yam).
Keep your pecker up and above all remember, photos or blah blah blah....

Yeah, haven't managed to contact my friend yet, may just have a run up to see him tomorrow.
I was over seeing my Father in law today in Sheffield so didn't get time. Like I said it's his time doing the CAD setup which is quite a big favour to ask, but we'll see.
I know pics or it didn't happen, I'll stick some up as always if it comes off.

All the best Paul
