For future reference I posted a snapshot of the auction. Nice looking pipe. Carbon fiber is nice. I have never considered that due to the price.
 
I'll await your comments re. quality & function. His feedback so far is limited to knee pucks & tire warmers. Racefit is now marketing in the U.S. as well, but as you said, their Growler C/F can costs several times this one. I planned on having a mid-pipe custom bent to accept a modern Yosh RS-3, but the diameter of these GP-syle cans being smaller, would look more fitting on our older GS bikes, I think.....also, these are less than 1/2 the Yosh price and very current, in terms of looks.:)

Yeah, his feedback was kind of limited (100% though) but judging from his replies via email he seems to be a very serious seller. Over here a Racefit Growler goes for $700, so paying $160 for a slip-on with the same sound and look is nothing short of a steal. That saves $540. Money like that can buy a lot.

There's a Japanese bike shop called Auto Magic that does a slip-on which looks pretty much the same but it costs around $600.

Expect a detailed review when I get it.

Also went down to the workshop today to see the final welds on the swingarm. Looked really good so I had to put it together for a full-view shot.

My reaction?

"Damn, that's nice."

It's a bit wider in the rear compared to stock. :D

Another job well done by me and my dad.

Did I mention? The shocks work perfectly. Could really feel that they are amazing from just putting my weight on them and pushing down. No more bicycle shocks here.

Also shotblasted the engine cover with some aluminium oxide. All nice and clean now. Gonna get it painted tomorrow if I get time.

Will be back at the workshop tomorrow to do a dry fit of all the parts. I'll post some more pictures then.

Normally you wouldn't consider stuff from China that costs less than half of something over here in the west. But fact is that just because it's Chinese doesn't mean it's low quality, in fact, they are probably just as good as many of the exhaust manufacturers over here. Their labour costs a fraction of what we ask but they are still great craftsmen.

Stuff you should look out for is Thai copies. No matter what it is - it's junk.

Sorry, I think you mis-understood what I ment; I would not have consided a Yoshi Carbon or other US manufacturers as they are very (too) expensive. Yes the Chinese make most everything these days as the manufacturing technology has been exported to there by most of the industrialized nations.


BTW, Bikes coming along nicely

Oh, I see. Makes sense now.

Well done...great project, luv this stuff!

Thanks!

Slight update. Brought the front end and all the bodywork with me to the workshop for a mock-up session to get some things straightened out.

After we put it together it was time for some testing. Dad was first up.

DSC_0001-12.jpg


He was surprised how comfortable it was. Next up was me.

The stance was a bit aggressive (leaned forward) so we raised it up about an inch to see how much of a difference it made. Felt much better afterwards.

Will be ordering some parts for the engine this week. More progress on the actual bike in a few days.
 
Oh yes...

Oh yes...!

Fits like a glove and as far as I can tell - works perfectly. Huge chunk out of my pocket but well worth it. Been hunting for these for a long time.

It is really nice when things work out and the anxiety of buying somthing that doesn't work disappears. :D

Exactly. Bought a few parts in the past thinking they would fit (having been told so) but for some reason, they didn't...

Really a weight off my shoulders, eventhough they were costly, well, not compared to new.

Where did you get those gorgeous velocity stacks? Me want....

Paul

Original Keihin FCR velocity stacks. Comes with the carbs.
 
Mindless I really like what you've done here so far. The bodywork looks sooo rad.
Great job.
I can't believe how big that drill press is!

You are going to love the throttle response on those. The sound they make is addictive too (rattle, rattle).
 
tank question

tank question

I have a quick question about the gas tank...I have a 1984 GS1150 ES and my tank came stock with big rubber tank protectors on it. I pulled them off but there are now big ugly recesses in the tank from where they were, but I noticed your tank has niether...did you fill them in with something or did your tank come without the protectors?
 
Thanks guys.

As for the carbs: Yeah, I'm really looking forward to seeing how they preform. I really like the Mikuni RS line of carbs but the FCR's are supposed to be a step above. :)

Filled them up with a fiberglass filler. ;)
 
Exhaust from China is finished and on it's way. Turned out great.

Can't wait to get it.
 
I would like one for a 750...available?

It's custom made so you get whatever you specify. Length, inner diameter, outer diameter, materials, etc. Just send him a message on eBay here.

He's been very quick to answer my questions both through eBay and mail so you can expect an answer within an hour (granted you have to take timezones in mind).
 
K I've got a couple quick questions about your front end...First off...what kind of forks are those off of? they look like ohlins but I can't tell...(very nice though) and second. Did you machine the triple clams yourself or buy them? also your handle bars...I have a similar set but no risers...I'm in the middle of machinning them and I was wondering if you just bought them or not.
