Yoshimura GSX1135R (EFE) Project

Man... you leave no things unattended, do you? (rhetorical question...)

Thanks for all the detailed pics of your work... VERY inspiring !

Pretty much. Only thing that's pretty much standard is the tank and sidepanels.


Started working on respacing the carbs earlier today. My intakes measure 77-98-77 but the carbs are only 77-89-77. I can't figure out how I managed to fit them to the bike last time.



Anyway, some new spacers and they will be good to go. Should have that sorted out tonight.

Shot of the new pipe between the collector and the muffler.



Significant improvement to what I had before I think.

That's looking great, just the perfect angle!

Though, now we're all intrigued to see the setup WITH the muffler...

Got to make one first.



Should start working on it this weekend.

It that a Deckel? I see German writing on the spindle.

I think it might be. Haven't actually thought about it. I'll have a look tomorrow when we're going to finish up the muffler.

Finished up the tube for the muffler today as well as the link-pipe between the collector and muffler.

Really happy with the welding though (no close ups unfortunately), didn't look like bird **** like it does sometimes when your hand can't stay still...



While I welded the pipe, my dad took care of the lathe work. The tube was 90x5mm (80mm inside) and needed to come down to 85x2.5mm (still 80mm inside).





Cut made to fit the rear flange to the muffler...



Like this...





Gonna make the end caps tomorrow and cut it down to size (260mm). Hopefully I'll have a shot of the finished product then as well.

I LOVE the way that you have tucked in the exhaust!
When I re-do one of mine, I was just going to eliminate the rear triangle of frame (GS model) just behind the front pegs as that was the "weak link". (only place that I hit hard parts)

Update: turns out it wasn't a Deckel. Oh well, it's a good mill either way.



Anyway, managed to finish up the end baffles for the muffler today.

Man am I happy.

I'll get some pictures of the individual parts up later tonight.



298mm full length (200mm tube). I suspect it will be loud enough...



Turned a nice cone inside the end baffle so it flows together with the flange a bit.



54mm straight through.



Gonna be awesome once I get the link pipe cut down to size.





VROOOOOM!

Thats going to be so loud!
Where did you get that ignition cover from?

I wouldn't say so loud. The old one was 60mm straight through with only a bit of fiberglass padding inside. This one will have plenty more damping material and has "only" a 54mm inside diameter. Then again, the outward-facing cone will amplify the sound a bit...

The ignition cover is from a guy called Lloyd, he runs a small company in the UK that does custom billet stuff for oldschool bikes.

The Yoshimura ignition covers were part of a small batch he did but I suppose he could make more. Doesn't hurt to send him an email.

Some more shots...



End baffle (two pieces).



Front baffle.



Loosely fitted to the bike (a bit tight in the front baffle, need to open the hole up a bit more).









Dunno about you but I love it.

Thanks guys.

I sold the old pipe to a guy in England to fund the new. Was on a tight budget at the time so I couldn't keep it.
