Hi Guys,

I am new to this forum thing but seemed like a good place to get some advise, I have been riding for just over a year now and my one and only bike to date has been a daytona 955i in Red and i love it.

I took it for its first MOT under my ownership and it failed for reasons i can fix other then these two;

(a) the engine is revving when the bike is in neutral and turned to full lock but i don't know where to look or any possible causes, does anyone have any prior experience of this.

(b) an advisory notice was to change the brake fluid on the front, it already has braided hosing put on from the previous owner but i have no clue how to bleed brakes, is it something i can do myself or should i get the professionals involved??

Any help and advise would be greatly appreciated, I love my riding and my bike and I'm desperate to get back on the road while the sun is still out!!!

Sounds like the throttle cable is binding up along the way.

It is doable on your own, easier if you buy one of the assorted pumps. Though I can't imagine it being that pricey if you pay a shop.

"My four wheeled steed was contructed in Solihull "

Do you mean you drive one of the mighty green ovals??!

I also failed on my tyres and there's a local garage will replace them for me for £25, i got a good deal on a Bridgestone package from Demon Tweeks so I will probably ask him about bleeding the brakes for me, didn't realise it all needed pump work!!!

What do you mean by binding up, is it an issue within the throttle grip or catching somewher on its way to the engine?

Hey Boris955i,

Welcome to the forums. First off, I'll point out that if you own a 955i you will probably find more help pertaining to your bike over in the Daytona Deliberation forum; the forum we are currently posting in is for the younger brother Daytona 600/650 and other 600cc Triumphs. The 955i forum can be found on your main menu bar to the left or here: http://www.triumphrat.net/daytona-deliberations/

As for your throttle issue, skittles is correct that it is your cable binding up. This used to happen on my 955i. Make sure that the cable going from your hand throttle has room to move, because if it binds it will pull your throttle open. When the previous owner converted to braided brake lines he/she might have routed the throttle cable the wrong way. If you do not have enough room for the cable to move, try to find a new route and disconnect the cable up at the clipon and slide it where it needs to go (Just pay attention to how the two cables attach to your hand control.)

Changing the brake fluid is not hard, but there are little pieces of knowledge that if not known can lead to a huge headache. Use the 'search' tab on the upper blue horizontal bar of this screen and search for words like: bleeding brakes, brake fluid, mushy brakes, flushing brakes, etc. This subject has been widely discussed and you should find all the info you need. The key to flushing brakes is to never let air get into the lines, so don't drain the fluid reservoir empty and then fill it back up; you drain it until it is almost empty, add new juice, drain, add new juice...until the reservoir is replaced with new fluid. Then you can easily drain the lines while pouring new fluid in the reservoir. I hope that helps, and check out the Daytona 955i forum; there's a lot of good people over there to help you. Also, the Speed Triple forum will relate to you, as your bikes are almost identical up until 2005, and they too are very cool Rats.

If the throttle cable is routed the wrong way, it will bind and cause the engine to rev when you turn the bars to full lock one way or the other, but not both. Check the cable routing. If the previous owner replaced either the throttle or clutch cable, that's the first place to look.

You don't need a pump to bleed your brakes, but it makes life a lot easier if you are replacing all the fluid. Because you can reach the brake lever and bleed nipple at the same time, you can bleed them by wrapping a rag around the caliper and then open and shut the nipple while pumping the lever. If you haven't done it before, get a friend who has to help you so you don't just introduce air into the system. It is easy to do, but just as easy to foul up. It will take one try with a little instruction to get it right, so don't be intimidated by it at all. I just got around to buying a Mighty-Vac to ease brake bleeding because I am about to rebuild the calipers on the race bike, but I have got by for years without one.

Since this is about a 955i, I am going to move it to the Daytona forum, although the questions are applicable to just about every motorcycle ever built. Good luck with your bike.

Hey will good to hear from you not been round the Supers forum since I traded the S4 for the tona, Hi Boris, the guys there are right, follow the path of the throttle cable and you will find its getting tight somewhere when you turn the bars, thats what our American friends mean by binding, it should be free to move around all the time, as for the Brakes its just a matter of using the lever to pump out all the old fluid, its tricky to do on your own as you need three hands and arms as long as a gorilla, the basic technique is easy, best to do a search and follow what it says, the bleed nipple has to be opened, then the lever pulled back to the bar, nipple closed release lever repeat until new fluid comes from the nipple end, thing is you need a tube attached to the nipple and into a jar of fluid and never let the master cylinder get too low, pumps really help to simplify the whole thing, as for tyres check if a supplier can supply and fit as most will fit for free if you buy the tyres from them and you know your getting fresh rubber, some internet sellers sell off old stock cheap.
