It's looking like Curborough was a better idea :-)

ACU 5500RPM STD PIPE 94dba... straight through race pipe 105 dba
Are any 1000cc bikes ok a Castle combe, if so I would like to know which so I can try a silencer off one.
The kit cars with bike engines have space down the side for a huge silencer, unlike the tR1ke that is as on the R1 bike.

I know a few friends of mine have taken R1s to Castle Combe, even had to go and trailer one back a couple of years ago after he binned it! but not sure what silencers they were using

Tommo, Im not far from Castle Combe so when would be a good time to come up and do a noise test. I have 3 different sets of cans, including the standard R1, which I can use

Don't forget guys that if we all go around pushing the noise limits to max then there will be more circuit closures due to noise. If the car is road legal then it will be permitted on circuits. 100db is higher than the IVA limit.

Thanks for that, so ill simply re fit the standard yamaha exhaust system shall I. The very system that my tR1ke was fitted with for the MSVA, The system that is fully road legal and not modified. I wish it was that easy.

It's not too late to cancel Kitfest and re-book Curborough :-)
The R1 rocket launcher exhaust is a road legal silencer and should pass any sound test surely?
Bad move moving this event to Castle Combe with all it's sound restrictions
Seems the only vehicles permitted are road cars.

Now that Castle Combes KITFEST website is on line I have made a formal application for a MEV Owners Group/Club pitch, on the grass, hopefully overlooking the circuit. Not wishing to bore you all with the details, but and especially as this is the first KITFEST the organisers are keen to gauge numbers. Although I've requested space on the pitch for 30 cars! yes I know its a lot but if we're going to get a exclusive track session organised we're going to need at least 28. Anyway they'd like me to notify them of registration numbers, so anyone attending and parking on the Club Pitch please PM me your reg.
Also I've learnt that there is the chance to win a free exclusive track session so I've put us in for that as well.
On the web booking page there's no mention of any afternoon sessions and I've asked the organisers to clarify.
Maybe Neil would like to clarify directly on the forum or if I here anything I'll let you all know.
The 5th AMM will be held at KITFEST this year, we've had 4 good years at Curborough and it remains my goal/intention to try and find a multi car circuit for the exclusive use of MEV Owners, however until such time as I can get sufficient numbers to participate and support the yearly event, financially its not viable. With KITFEST being on the same weekend this year its just pointless to run Curborough, so lets all make the effort, (its a long trip from North Wales for me) and attend KITFEST.
What we end up doing in 2015 for the 6th AMM is anybody's guess.
I'm sorry to read about the difficulties that the tR1ke boys are having re sound, and I know Curborough was 105dB, this is especially annoying since we've gone to some lengths to get a special dispensation for the track organisers to get the MEV tR1ke accepted at on circuit, as trikes are generally not allowed. Now I cant believe that having the skills to build a tR1ke in the first place precludes owners from finding a low cost solution to the noise problem. So please please get the grey matter working find a solution and get those MEV tR1kes on track.

To be honest Nigel. If the road legal factory fitted exhaust is too loud for this circuit then I imagine you would have to pay an expert fabricator to bespoke make an exhaust for this ONE circuit.
So maybe £1000 for a complete system to qualify for the legal requirements on this track.
I will stick to road driving, where I can easily run my 108DB exhaust without any issues.

Hi Nick, just had a quick look at the MSVA regs as the tR1ke comes under those rather than the IVA ones. How then did you get it through as the MSVA calls for 99db? (which is lower than Castle Combe)
Surely this can be solved by changing the can rather than the whole system? How will RTR get there tR1ke on the circuit then? Could RTR make up some quallifing cans? and if not to sell, could they offer to rent them to tR1ke owners to go on circuit. Sorry just thinking aloud Nick, now I'm probably going to get into trouble with Paul at RTR.
Anyway if i remember rightly your system had problems at Curborough.

now I`m confused. just been looking on google about the difference between db and dba. plenty of cheap noise level meters on ebay but it looks like they all measure dba which, as tommo said is different to db. maybe the best option is for me to go and get mine sound checked with my quieter cans and see how bad it is. Doesn`t look good when castle combe web site lists a standard -from the factory- 2008 model r1, along with a whole list of others, as too loud to be on track.

Just got an email back from Paul at RTR on the subject:-
Question:-
Hi Paul,
Having a bit of a problem / discussion on the Forum re tR1ke’s meeting the noise limits at KitFest and be interested in your views. How are you going to run your tR1ke? Is it below 100db? If not how do you get it passed MSVA?
Your input on this issue would be greatly appreciated. Nigel
Answer:-
Hi Nigel,
tR1kes with standard Yamaha R1 cans sail through noise regs at MSVA and are well under 100db.
Our first tR1ke had 2 race cans on and that scraped through the noise test at 98.8db, but full chat was well over 100db.
Tr1kes will not be an issue providing they are not fitted with screaming aftermarket cans. These 'loud' cans sound awesome on the road, but won't find any friends at Castle Combe.
If common sense prevails, there will not be a problem.
All the best,
Paul.

Be great if you could find the time to get your tR1ke sound checked at Castle Combe and report back to all. Paul at RTR takes the view that standard cans will meet the requirements just fine. nigel

I'm really keen to get as many MEV tR1kes out on track as possible, as there acceptance on such a prestigious and recognised circuit as Castle Combe will give us further leverage on other circuits for the future where historically 3 wheelers are somewhat frowned upon. nigel
