I'm reluctant to answer your original question in case it puts an end to what is a pretty entertaining sparring match! (I think you're ahead on points so far!) So, from a Vertigo owner's perspective, not really. Not a difference that your neighbors would notice anyway. However they are really good bikes, so personally I would go ahead and get one even if it does risk upsetting your neighbours. At least you have no risk of upsetting them from the use of a noisy lawnmower . P.S. Use map 4 for the hill climb, it will be a blast!!!

Decided to give the OSSA another make over. After 360 hours running time it was looking and performing a little sad! My Son in Law has been riding it for the last couple of years so it didn't get too much love and attention for a while! I made the mistake of riding it myself again and discovered it was pretty tired. So total strip down revealed multiple wear related issues. Mainly piston and barrel that was badly scored below the ports. So lots of new bits and and a paint job later and it is like new again.

The red ones are standard ones painted a red candy. The gold ones are X Block clamps that were originally red but have been painted to match gold anodising. The black OSSA graphics are a combination of paint, immersed imaging and decals under a Matt Clear.

Both standard 2012 280's originally. The green one is now a 300.

My Son In Law drew it up in CAD and had 10 laser cut and folded by an engineering company. I still have 9 left!

Just get it. You know you want to. I've owned a 2012 TR 280 since new. Starts first or second kick with no battery. Issues I've had are breaking two selector shafts by hitting rocks with the selector. Since fitted a wider bash plate so no problem since. Most of the FI parts are generic and are sourced easily. Pistons/rings are no problem. Bores can be re plated. Fan is same as GG use. Wheels can be rebuilt. Suspension is generic so are brakes. I would suggest getting a spare ECU, set of leads, selector shaft and set of plastics. I could provide you with software and maps, even a wider bash plate. I would anticipate no real issues providing normal maintenance is undertaken. They really are great bikes.

Really sorry to hear this. You must be devastated. I restored the bike so know what you have lost. Really hope you are able to get it back and the low life that stole it gets what he deserves. Please keep us informed as to the outcome.

Sorry, should have been doctlrtls. Who is he? A very knowledgeable and helpful individual who I credit for providing me with the information that I am sharing here.

Hi shedracer, I do remember and am pleased to have inspired you to locate and build one. I'm sure you will do it justice. Yes I do remember your interest in acquiring mine. It ended up in a collection owned by Paul Arnett who is the owner of the Hell Team Trials store here in Australia. (Swapped it for a new JTG 300). For me the pleasure came from the build rather than owning or riding it. It can be frustrating, especially sourcing parts and information. The best provider of info I encountered was doctlrrtl. His information on the fitment of the cooler was invaluable and I am pretty sure without it I would have got it wrong. Cheers

Hi shedracer, It is vital to use the 8mm plug when fitting an oil cooler as it closes a gallery and diverts oil into the cooler. If it is not fitted the oil will just return into the crankcase. I made mine by cutting one from the shank of an 8mm drill bit. I was a little concerned that the oil pressure would not be sufficient to feed oil back to the camshaft with the line being piggybacked to the crankcase return. All was OK however and this should be checked by removing the camshaft cover and turning the motor over by hand. If everything is done correctly and the pump is in good condition, just slowly turning the motor should push oil through the camshaft.

Nicely done fantic 303. love your work! No doubt you will also be criticised by some for the incorrect placement?? I have included another picture that clarifies oil flow through the cooler. Hope it helps.

I hope these images help. This is the correct way to run the lines.

K Scan software is very basic. Simple diagnostics and set up functions. K Write pro enables map upgrades. Cost was $500 sourced through the Australian importer. (spent more than that on getting the Keihin sorted on the JTG). I believe that generic leads are available now at a much lower cost.

2012 TR280i. Hundreds of hours riding. Hot, wet, humid conditions. Starts first or second kick always. Runs perfectly always. Never had to replace any EFI component. I have the cables and software so diagnostics and remaping is no problem. Only thing I did to make it work was fit a small 12v flight battery. 2014 JTG 300. spent hours and Hundreds of $ upgrading to a Keihin to get the best performance out of it. 2015 JTG 300 Racing. Half dozen kicks to start from cool (Never really cold!) Starts first kick when hot. Runs perfect.

Try these guys. www.cmsnl.com I found the majority of parts I needed here.

I guess everyone is entitled to their opinions, however the view that technological development of bikes is likely to be detrimental to the sport is in my opinion a very odd perspective. (You may not have noticed, but technological advancement across all areas is a fairly well established objective for the producers of pretty much everything!) I applaud Vertigo for their desire to fund, design and produce what appears to be a very well thought out, great looking and well engineered product. I have no doubt that it will perform as good as it looks based on the input that the brands ambassador has had during the development phase. (And lets face it, it's not really breaking new ground in the world of motorcycle engineering). I imagine that it will also be as durable and reliable as any other Moto Trials bike in the market. Sure it will no doubt have some teething problems in the early stages of production and I guess that's to be expected. Do I want one? For sure! Would I buy one? Absolutely! But then I also own a 2012 OSSA with that new fangled fuel injection and and a 2015 JGas 300 Racing with that odd styling and funny one sided shock! Good on ya Vertigo!

Definitely not riding at a high level. Did I need it to be better? No. Just like things to be as good as they can be and don't mind spending the time or the money to improve things. it's a challenge! The world of aftermarket accessories and performance aids would not exist if other people did not seek the same. Plus manufacturers would not offer factory models. Pretty sure the dealers are happy to support us! Go ahead and get one if you're keen. its a great bike out of the box, just not quite perfect! (Is anything?) Thanks for the advice on the plug gap telecat. I fitted a new plug and set the gap as per the specs in the manual. Bike ran pretty rough afterwards. Fitted the old plug back in and all was good. I put it down to the new plug being faulty. What gap are you running? Do you know why the wider gap improves performance? Cheers.

After trying multiple variations of jetting and slide changes in the end I gave up on the Dellorto. I just couldn’t get rid of the slight lag and I also felt that it was restricting overall performance. As a consequence I bit the bullet and bought a PWK Keihin, new reed block and throttle cable. Fitting was not at all straight forward. The Keihin is shorter, the float bowl and especially the drain outlet fouls on the engine casing. The breather is pushed up against the exhaust and cuts of the air flow and you are unable to level the carb! Oh, and the cable entry doesn’t seal and leaks water into the carb when washing the bike. So modifications are required to enable fitting. Firstly had to make a 6mm reed block spacer to push the carb back and up off of the casing. Removed the bottom carb drain and drilled out the vent on the LH side and blocked off the vent on the RH side that was hitting the exhaust. Fitted a boot to the cable and sealed the cable inlet. All now good. Initial set up was a 3.5 slide, 48 pilot, 125 main, JJH needle 4th clip down. This made a significant improvement in performance unleashing the potential that I felt was always there. However, off idle performance was not great. Worse that the Dellorto! Made some jetting changes to no avail. So on the advice of Paul from the Hell Team, fitted a #3 slide and a 45 pilot. The feeling was that due to the larger intake diameter the initial vacuum was not sufficient to draw fuel. The smaller cut out increases vacuum thus enabling faster fuel delivery. It was also suggested to fit a flywheel weight and to go back to the higher compression head so I made these changes also. Outcome? Perfect! The fuelling is now spot on. Equal to the FI OSSA. No lag, seamless response. The Flywheel weight has noticeably improved traction. Power is great. Hill climbs are a lot of fun! Shame the factory doesn’t deliver them with this set up? I am betting the factory models will have a Keihin when they become available. So now really, really happy with all aspects of the bike. Now to see if it improves my ability!! Thanks again to those that offered advice. Hopefully this will help others looking to unleash the performance these bikes are able to produce.

Tried a 38. It was worse. Best was a 31 for minimising the lag but was then too lean during transition. I have fitted a #50 slide to increase velocity and richen it during the transition phase. Haven't tried it out yet though so no idea if it will help. Also ordered a Keihin today so will give that a try.

Thats great info. Thanks

I may give a Keihin a try if I am unable to improve things with the Dellorto. Would you be willing to share your set up for the Keihin? Slide, jets, needle etc? Did you have to change or modify anything in order to fit the Keihin? Cheers

Hi telecat, What improvement did you gain via the fitting of a Keihin (and what prompted you to)? I did consider going this way (and still may) but I was informed that the benefits are gains in mid to top performance with a sacrifice in initial response and bottom end. Would you agree? Cheers

Recently I became the proud owner of a 2014 JTG 300. I am really happy with the bike in general, however I would like to improve the fueling if possible to overcome a slight lag just off of idle. I should also point out that I may be being perhaps a little to fussy as the lag is by no means terrible. However I have been spoiled by having an OSSA TR280i with pretty much perfect fueling. To date I have tried multiple jetting, clip position, idle screw and slide changes with no real improvement from standard. (120 main. 35 idle. 270K emulsion tube. 60 slide. 36 needle) The bike is also now fitted with a low compression head to combat pre ignition issues. Running 98 octane fuel (Suposably). Altitude is sea level to no more than 500 meters. Based in Brisbane Australia. Winter at present so conditions are warm and dry. I will keep trying but was hoping that someone has come up with the magic combination and would be willing to share? Or just let me know that I am being too pedantic (possibly), and will never equal EFI perfection. Any suggestions gratefully received. (Perhaps Jotagas would care to comment?) Cheers

I have a 2012 TR280 running ECU 11 firmware and map #15. Just wondering if this is the latest map update for this version or have more been produced? I used to get updates from Bob at OSSA Canada but that is no longer an option. Australian distribution and back up is not much help at present either. Any suggestions? Cheers

Not sure if this will help. http://www.cmsnl.com/honda-tlr200-reflex-usa_model1107/partslist/F++07.html#results
