Yoshis From America ?

[Stretch650]

Has anyone tried this??

I am looking at a full TRS system from these guys - http://www.morepowerracing.co.uk/ and looks to be half the price.

I know its still gota come through customs but is unlikely to make up the difference is it?

Any success/disaster stories?

Who did you use ?
Cost effective?
Warranty?

[Dangerous Dave]

I would do it, the added cost of import tax usually still adds up to less than the full UK price.

Warranty might be an issue, if the exhaust isn't intended to be imported into the UK by Yoshimura then they may not expect a warranty claim.

On the plus side, Yoshi make a great exhaust so make sure you keep it nice and clean!

[G]

I have a carbon Yoshi RS-5 on my 600RR

The cost in the uk is £580......I paid £300, so nearly a 50% saving.

It wont have a UK valid warranty regardless of what anyone says.

It got through customs with no charges.

It took 2 weeks to come after they got the right order and sent the wrong one intially, it was quite a stressful time as you have next to no comeback.

Pay by credit card.

Any Recommendations of which US store to get from ??

These are good....

I chap serving here got a full Titanium system from his GSXR from these guys, think it took a week to get here and I am not sure how much the tax was.

[G]

I dont like recommendation incase all goes to pot for the person.

I used universalelectronix...........they get some good reviews and they get some bad ones.

My story went like this......

Contacted them and paid via paypal/credit card.

They sent me an exhaust which was for the wrong bike, I sent it back to a coventry address and heard no more, contacted them again and they said they had dispatched another exhaust.

Another week went by and nothing.

I pestered and pestered for a tracking number and eventually they gave me one.

Then it took another week or two for it too finally arrive.

They eventually refunded me the cost of sending the wrong one to coventry and never gave me any feedback.

It was rather stressfull but they do have number you can contact them on, but time difference are an issue.

The upside, I got a very cheap exhaust for £290 less than UK prices.

They label the package up in such a way that it avoids custom & Excise charges......if it got lost in the post I dont know what issues you would have with insurance and values.

Go collect - much easier ;)

It's what I did with mine...

Would love to but some how dont think that is going to work out cheaper!

I have been quoted the following from Steve Jordan Motorcycles

Yoshi Full TRS system with Carbon Can - £610
Fitting - £75
ECU Remap - £150 (seems steep - they do say NOT Yoshi Box - so not really sure what they do)

The price for the system from the US is $658/£375 before any delivery or customs and would then still need to have it fitted and the remap done !!

Looks like a lot of effort and risk to save at maximum £200.

Am i missing something ??

[G]

There is some hassle and risk to some extent but a saving of £200 is a good saving.

For me it was a saving of £290 so even better.

[Stretch650]

True but thats only if it makes it through customs undetected and then no warranty or comeback . Hmmm i am torn

[G]

I guess you take your chances and risks......some pay off, some dont.

You need to speak with the shop and get them to label the box as a warranty repair/replacement item - No value

Then it will get through customs without any charges.

[mr.anderson]

Fitting - £75

There's £75 you can save already.

Fitting it is half of the fun!

Fitting - £75
ECU Remap - £150
Fit the system yourself, its easy, and that is very steep price for a OEM ECU remap!!!

When you customise a bike it is far more rewarding if you do the work yourself.

[Stretch650]

Think i am going to do that - i know how to handle a spanner so should be able to get through it! (are there any threads of someone who has done the whole system - been searching but not found anythin yet)

Only 2 questions remain ....

Best place in greater London for a stock ECU remap and what should i expect to pay?

Can i keep a legal can and fit it to the Yoshi system pipes come MOT time??

Thanks again for all your help.

Around £60, anywhere above £100 is overpriced.

Yes, when the Yoshi arrives measure the link pipe diameter and find a can the same size or you could get any can and have a link pipe made to fit.

Hello:cool:

Not been about for a while but a quick heads up on the OEM remapping. We dont offer what other shops often call an OEM remap. The one we do is not via a Yoshi or Teka box and remaps the stock ECU fully. It takes 3 hours to do hence the £150 cost.

Anyone offering one for £60 isnt doing it properly.:cool:

[Dangerous Dave]

Thats a bold claim to make when reputable tuners offer the same service for £60-80 and have had no problems or bad comments made against them!

A Yoshi done properly does remap the entire ECU!

[SV650Racer]

Hello.:cool:.

I dont know of anyone else using the same system. Doing it properly i was refering to completing a full remap. Not one done via other systems such as Yoshi or Teka which dont have a full range to remap like a PC or the system we use. A Yoshi box will only alter to a certain limit and often a limit which isnt enough.

Thats all. Failing that as it takes 3 hours to complete (like mapping a PC) £20-£26 an hour labour is bloody cheap!

No more a bolder a claim than suggesting £150 is overpriced!!

Just curious, what is it you do to the ECU that they don't? Is it the use of a dyno (mate had his 'remapped' but they didn't use a dyno - suspicious IMO)? I would've thought otherwise that a remap is a remap, but obviously quality can differ...

I am ordering the rest of the Yoshi system I've got, was considering popping down to you to get it mapped (to get the standard ECU mapped, rather than buying a PC3).

One question I have is that Yoshi (USA) state that putting the carbon fibre can on a dyno can damage it (too much heat) and as such it voids the warranty - do you know anything about this? Can you do anything to prevent this, such as pointing a dyno fan thingy at it? That's the only bit I'm really worried about, TBH!

Spending all day on a dyno yeah, but one or two runs isn't going to do the damage.

[muffles]

But if it's 3 hours to do the remap, it's gonna be quite a long time no? Just going off what is posted above :D

Aye, but it won't be three hours running on the dyno as most of that time will be spent remapping the ECU.

[muffles]

Aye, but it won't be three hours running on the dyno as most of that time will be spent remapping the ECU.

True...but what would Yoshi put a warning on there for about dynos, if it was not risking damage? I know what you're saying...just a nagging thing in the back of my head, cos at the end of the day if I put it on and it blows up, it'll be me paying out :(

SV650Racer/GSXRRacer ;) I look forward to your view :D

I'll try and dig up the exact text of the warning a bit later - got it somewhere, I think.

[muffles]

Oh and just to add...one of the bike mags (I forget which, but I have the copy) blew up the CF end can on their micron full system (for a K8 750 also) by putting it on a dyno - that was kinda worrying! :lol:

Is spoke to the guy at Carbon Can Company yesterday as i ordered a Carbon Oval and asked him the same question about carbon and its resillience.

Companies like Beowulf dont even do carbon cans for the SV as the say that the resonance can damage it. BULL says the guy at CCC. They currently make all OEm exhaust systems for TVR and have been doing so for some years out of carbon. They have not had any problems and he said the chances of a Sv (or any bike) causing more resonance or heat is extremely unlikely! Compared to a TVR i would have to agree!

He also said that it is all down to the carbon weave and resin they use. They are happy that theirs can handle it so i suppose it is all down to the manufacturer and the quality of stuff they use !

Anyway just the messenger on this one :p

How about this for a resolution - I will take my bike to one of these £60 Yoshi Box tuners and get them to do a custom mapping on my bike. I will then bring it to you guys to do your mapping - we can then compare Dyno results - If there is a significant improvement I will pay - if not i dont!

There will then be clear evidence that your way of tuning yields better results hence settling a lot off arguments and sending more people your way for a "proper remap"

Are you willing to take that challenge ???

[SV650Racer]

Hi Muffles.

Fuel mapping can only be done correctly if you know what you need to adjust. You need an Air fuel reading to show you how lean or rich the bike is running at certain throttle openings and gears under load. The only way this can be done is on a dyno. Im not sure how you can remap without the use of a dyno as you dont know without the air fuel reading how the bike is running. Thats like playing Russian Roulette as you wont know what effect the changes your making is having!.

Yes Carbon cans, especially carbon end capped cans can blow out or weaken on the end tip during remapping. A single air fuel run wont harm it. BUT to remap the bike is running on and off for upto 3 hours. The off time is to allow the bike to cool and the dyno room to re-charge. Mostly its caused by the carbon being of poor quality. Akro's are particulary affected as the carbon they use isnt as good as it used to be.

A friend works for an F1 team and we had a tour round their "clean room" where they lay the carbon to make the parts for the F1 car. There are many grades of carbon available and also resins. The baking process can also affect how the carbon responds to heat. He reckons they are using a cheaper grade that often hasnt been baked long enough.

A carbon can though if well made will work perfectly ok on a Vtwin.

Im having made a new type of exhaust fume extractor built to help keep down the temp around the exhaust to help stop this from happening.

So far though i havent had a problem with Jap Yoshi's or Scorpian exhausts.

Hope that helps.:cool:

Oh and yes more than happy to get the bike run up after its been "remapped" off a dyno via a Yoshi box. It wont be the first time we have done that!

Interesting, and good to know - hopefully will take it round to yours when the time comes then! If it's ok would still like to be very careful when doing it, i.e. checking the temp of the carbon regularly, as mentioned it'll be me footing the bill if it does go so I have an investment to protect :p

Anyway need to get hold of the rest of the system first, which isn't happening until at least christmas time (as that's when I'm flying out to the US).

I guess the last point is directed at Stretch650 :D

[SV650Racer]

Coolio.

Have just imported in a Titanium R77 system for my 600. Looks so sweet!. Couldnt afford the Jap Ti race system but the R77 looks just as nice.:cool:

Nice, it's the R-77 I've got too. Although I will only be buying the S/S headers, the Ti is expensive enough that the people at Yoshi USA recommended I sold my end can and bought the whole system if I wanted a Ti one!

[SV650Racer]

I understand the finish of the end can doesnt matter, well for the GSXR600 fitment anyway. As far as i can see the R77 can from the stainless system will fit the Ti system. Unless the bore is different as the Ti system is classed as the race developed part.

[Dangerous Dave]

Are you willing to take that challenge ???
You'll have to speak to Crescent, they do all the remap work for me as i am a guy in his own garage (although I still built an SV800 in it).

Yeah I think fitment (and finish) is the same - it's just that buying the parts separately, it didn't make any sense. I guess I'm losing out a little as I'm buying the S/S system separately.

Unfortunately I don't have figures for the Ti as I use my contact in the US (ok ok father in law but that doesn't sound as good :p) and he didn't question further on that comment by the Yoshi person!

[yorkie_chris]

Pah ... should have carbs. Jet it by rse. Taken me 6 months but it's spot on now! :-D

[muffles]

I'll try and dig up the exact text of the warning a bit later - got it somewhere, I think.

This, my friends, is later :cool:

The text actually says (context is that it is talking about care of the exhaust):

Repack your street exhaust system every 5,000 miles. Repack your off-road system every 8-10 hours of use or every 2 motos, whichever comes first. Carbon Fiber will be damaged without the protection of proper packing. High temperatures (such as dyno testing) will cause the resin in the carbon fiber to break down. Note: This situation will void your warranty.

It seems a little unclear - it's not strictly saying that dyno testing voids the warranty - but that high temperatures void the warranty, of which it considers dyno testing to be an example. I guess if it came to it, if you could prove the dyno testing did not cause high enough temperatures, you might have a get out.

But, none of that applies to me, because a) my warranty won't stand, or at least will be difficult to use, and b) if my can blew on the dyno, it would probably be because of the temperature, and thus any warranty most certainly would be void!

As mentioned I still want to be able to put it on, I just need to have some confidence it isn't going to all go wrong :)

[Dangerous Dave]

There are loads of Carbon Yoshi's in the UK on many bikes, you should be ok.

[muffles]

Yeah I was thinking the same....just that Yoshi quote above got me worried - not that it would void my warranty, but that it would actually blow.

As you say...should be OK though...SV650Racer also says this, so 2/2 and I'm convinced :p just gotta get the rest of the exhaust, should be ordering it tomorrow assuming the price hasn't changed (in dollars, the exchange rate is obviously a bit volatile at the moment).
