I bought a pair from RTR, I didn't honestly like how they looked on, so had some nicer ones made, they were useless, made my head bob around, had to hold my sunglasses on at 70MPH, Kevin trailed his own large screens, and these worked, but the were massive, in the end, everyone seems to go back to standard humps, and wears a helmet at speeds over 40MPH.
May have to make some wind deflector screens as my helmet starts trying to lift at high speed.
When we were in the wind tunnel at MIRA, they explained to us that the best kid of wind deflectors are horizontal. They demonstrated with some smoke how a vertical deflector shoots the air upwards which is why we see them on F1 cars and of course the Ariel Atom.
If you use a bubble shaped deflector then you have to be behind it and looking through it for it to work. If you are looking over it, the the air will simply rush over the top of it and hit you in the face hence the wobbly helmet.
Our deflectors are simple hand cut pieces of polycarbonate but positioned correctly, they create a narrow column of clean air that lines up nicely with your helmet.
If you go down the DIY route, make sure that they are vertical and don't worry about the tiny bit of drag that they create as it is no more than when the airstream hits you square in the face without them fitted.
I'm sure the RTR ones Do work, and I haven't heard complaints about anyone who has fitted them saying they don't work, I just personally didn't want to fit mine. I fitted my neon green ones, which didn't stand as tall ( my mistake when drilling them) but after finding they added to a helmet bobbing problem I removed them. :-)
Anybody had any problems with insurance and club membership discount. Graham Sykes have written to me again asking for current mot and copy of club membership card. I rang them and told them that when i get a current mot certificate, in 3 years, they are welcome to a copy, and that the mev owners group is an internet based club with no membership card. Apparently this is not acceptable, and they want to charge me the £38 discount I got for being a club member. I have just had a look on the web, and it seems all clubs are pretty much internet based and dont give you a membership card. I may have to ring them again Monday and see if I can speak to someone else who might understand that everything is now on the internet. If anyone knows of a club I can join that will cost me less than the £38 they want to charge please let me know.
Just been out and ordered a power commander and setup on a dyno at circuit motors, castle combe through Tim Blakemore racing. tr1ke is fantastic with some revs up, but running at low speed it seems to have a little bit of a misfire and generally not running smooth. Tim Blakemore is confident that the power commander with custom mapping and all set up on a dyno will cure the problem. plus on a dyno , I get to find out how powerful it really is. Hopefully this is all happening next week, so should be good and ready for the run to Stoneleigh.
Erik, have a look at timblakemoreracing.co.uk definateley a bike mechanic, unfortunately his dyno will not take the tr1ke, but they have one at castle combe that will, so I have to take my tr1ke and meet him there to do the work. He also said it would be no good to use standard power commander maps as there is so much change from the bike. ie: no cat, different cans, altered gearing, more weight and a few hundred metres of extra cabling between engine and ecu.
also taken the seat covers I started making a while ago in to get them stitched up. Made a tr1ke logo and embroidered it in the back panel in orange to match the bodywork. Forgot to take any pictures, so will post some up when I get them back
Lets hope they have good strapping points on the dyno, the biggest problem will be maintaining grip from the rear Tyre when under full load.
Also setting it up now makes sense, as Yamaha designed the air intakes in the fairing to direct the air flow to the air box. Now that the air box is uncovered ideally the settings will need changing, this is possibly part of the cause of you problem, along with the loss of the cat and open silencers that will cause it to run leaner
I'm looking forward to the results to see what she'll do. But low rev driveability will make it more manageable, you could see from your vid that it was a little snatchy at small throttle openings.
I have a newer model also and had no problems whatsoever... The initial settings performed well, but after installing a PC the power became slightly more smooth. So, it should run good without any modifications. Are spark plugs and valve clearances ok?
