CB350f (466 big bore) - she runs!

Update on page 7!

I've introduced myself here:
http://www.sohc.co.uk/index.php/topic,11327.msg84751.html#msg84751

Will continue in this thread with my project updates.

----------------


Hey guys,

just wanted to show you my re-upholstered Giuliari seat. The guy who did this is a real artist (www.toniworks.nl).
My original seat cover was ripped, torn, etc. so needed to be re-done. The choice was to go for an original-as-possible new cover, but we had a one hour brainstorm and came up with a plan to give it a little custom twist (as my bike is also almost original, but with a twist).

I'm super excited with the result:










I'll make some better pictures with a decent camera later, but I couldn't wait  ;D

Nothing wrong with those pics.  The quality of that seat is outstanding.   Is that leather or 'other materials'  ?   
If you don't mine me asking, how much did that come to?  I've fitted a genuine BMW seat cover to my K75 but it's a bit thin and has punctured so I'm interested in something like yours,  maybe next year.

I actually paid a little bit too less. He quoted me before we did the brainstorm, and the amount of work (logo's + diamond stitching) came to more then he anticipated (there is around 12 hours of work in this seat). But he was enthusiastic about the design and came through for the original price.
This should cost around 400 euro's including material (again, I paid less).
The cool thing is, that you can be done for 200 euro, getting a "standard" seat cover without anything custom, and you can make more budget for all the custom work as you like. For instance embroidery for logo's is quite expensive work, which is why we went for this 'rough' cutting and stitching of logo's, but with all the small cuting work there was still a lot of time required.

The material is "synthetic leather" (is it called skai in UK too?). With this guy, you can pick whatever material you like because he has specimen, much like when you buy new furniture.

I don't think real leather is very common on seats due to the influence of rain.

Update on my three-fiddy:

Changed the silencers for shorter ones, because the red-tips just came in too long to my taste:
I went for the peashooter style "hooligan" cans (little did I know this name reverts to the sound):






Especially the 3/4 from the front is much better in shape, where the old red cans just stuck out way too far.

And those with very sharp eye sight may have noticed in the previous pic, I added one pig-watcher on the left handle bar.
It seemed cool to have no mirrors (and no indicators for that matter), but after many miles on my more modern bike, I felt handicapped without a mirror...
So went for a simple black bar-end mirror.

Very nice workmanship there, top quality. Did your seat upholster supply the foam also?. Bike is a cracker also, very nice

Nice spring day in holland today, so went out for some fun.







Thanks for the compliments all! Much appreciated.

The sound is... LOUD. Less of a screamer compared to a 4-1.
I would say pretty similar in tone compared to my old (inside) rotten 4-4, but without the rattle of rot ;-)
Pretty deep tone down low and really winds up higher up in the revs.

It's pared 1-2 / 3-4 indeed, with custom made Y pieces on each side of the frame.
It's similar to the 4 in 4 of the 350. Those are connected too, albeit a bit further back in the silencer.
After the Y pieces come a standard connection pipe with a 30-ish degree angle. Then comes the silencer.
Headers are original (chopped) of the 4in4.


It runs OK in the higher revs, but it won't idle comfortable yet. Also from idle away it needs feeding in order not to stall.
However I still need to make real work of the carb settings. Fiddling with that every ride now.


With regards to the seat: the upholsterer also did a renewal of the foam, but this being a original giuliari seat, means the bump is actually metal. There's a little storage space back there too.

So, today a nice spring day in Holland. Decided to use it for some tinkering on the cb.
I set the valve clearance and replaced the ignition contact last week. So rode around to get some heat in the bike and connected my meters.

It turned out she was really waaaaay out of sync.
What a difference this makes!

I think i have the sync quite well now:

Idle is good. Revs are good.
Nice popping and brapping in the exhaust when throttle is closed.

Only improvement should be the pick-up from idle to throttle. It feels like it dies and needs some throttle play to run in revs.
Any advice?
