Cynic

Crikey, odd sport. Japs are pretty serious about it. I would have thought the r6 a bad choice but have just seen a video of a jap guy doing just fine on a honda cbr600rr. Was a pretty new fi one though. With a big fk off billet rear sprocket. I would guess from my limited use of an r6 that your asking it to do what it cant do, your expecting the engine to perform at 4k, an engine designed to hit 14 or 15k rpm flat out. This is a bike that recreated the 600 class with 2stroke type power, clue being the '2stroke like' That means no fun stuff till the engine has some energy to it. And in the video's I didn't hear people reving the spanglies off their bikes, you wont brake an r6 on power with the brakes they will cook. There was a rider on an XJR, bet he didn't crank up the idle speed and use the brakes, he was turning the fucker 360 deg in less than 2 bike lengths. I would think to get it down to make lower power I would really take the piss with the gearing, add 10 or 15 teeth to the rear and what you dare to the front, wont matter too much if you go too far you can just use 2nd instead of 1st. Or is it a road bike too?

I deliberately bought my jacket and trousers in august from my local bike shop deliberately because I can pop in for odd bits or just a brew. I know I could have saved a little buying on line but its not always worth it. I could not have tied on five or six jackets and as many Kevlar jeans with my other bike kit to make sure it all fitted just so on the internet. Or popped out to the car park to try em on my bike. Shame.

Good luck, hopefully its just a few tweaks.

Just PLEASE make sure it is someone YOU trust and respect, with the story your going to tell them a less than straight conscience could have you spanking easily over a grand straightening things by microns. The frame may have been bent, may not, but again a less than perfect 'expert' could throw that on the quote as changing a frame is an easy job on an essentially good bike and they can hit you for a fortune in labour. Not to mention the bike having a frame change recorded to it at dvla. Then the sundries, bent brackets and such. Not all of em are thieves but you could be waving a blank cheque in front of some.

Think he was planning to but his battery was flat..

Cheers john, just reread and, ahem tidied it up a little,

You sure, someone known for "iron butt" challenges.......?

Is that instead or as well as the camel.

Really Steve, he wears tassels and sequins in his spare time, If he was camping with Bippo and Dirty DT, may be Dirty who was more nervous.....

SSSSSSSSSSSHHHHHHHHH!!!!!! Merry Christmas everybody, Had my Mum and Dad round yesterday and my Mum drove so Dad could 'try' some of my 20Yr old port. Well both bottles are empty and a very good day was had by all. Ouch...

oops, split thread, locking this half.

9000 commuting miles in 11 years. I think de-restriction is the LAST thing you should be looking at. That bike sounds like it is choked, if it were me I would be getting myself dirty stripping the top end down to give it a decent decoke. Your engine will have built up a residue of hard carbon, soot! basically with oily remnants in it that bakes hard blocking the gasflow. Strip out the powervalve and clear the coke from that as well as the carbon changes the shape and volume of the port killing power dead. You could even start improving things at the same time, matching up the powervalve halves and smoothing off the raised id castings will help. (they are separate castings and generally fit together pretty poorly). If you are not afraid of a set of spanners, a manual (£15) and a set of top end gaskets (£30 with a genuine head gasket, I repeat GENUINE) some oven cleaner for the exhaust exp chamber then you can do a full decoke and you will have all your ponies back. Not very scientific but shove a hosepipe up the exhaust all the way into the expansion chamber, should be about 3ft then pull it out. If she is badly clogged even that will make a difference. Its normally the reason why exhausts seem to give big horsepower gains. You should expect 5-10% from a pipe, that's around 1.5-2hp. Noticable with a nice noise andmaybe concentrated towards the top end. If your exhaust is coked up, which happens disappointingly quickly unless a 2 strike is used as intended which is hard, not gentle commuting. You could be 5hp down when you fit the 'superpipe' which appears to give 7-8hp which you will really notice. Wow, good advice and a long post with a hang over.....

Congrats. Now enjoy any freedom/money/sanity you may still posses cos that little bundle of joy will own you for the next, oooh lifetime..

Nope, what you got is about it, you have no spare horsepower. Whatever you do will hurt either acceleration or top speed and quite often both. The gearing is a balance between all the ratio's, crank to gearbox, gearbox to chain, chain to rear wheel. They all have an effect. There is a very real chance you could increase the gearing and go slower or even lose the use of top unless going downhill. Not really any options, you could lose weight (not joking its about 6-10hp/stone relative) but not a lot else, low drag clothing (leather instead of flappy textile), otherwise your stuck with it really. Call it a license incentive.

No. This thread is beyond old, locked.

Yep, only difference. You might find some tiny variation, the voltage regulator moved (79 to 80 not far though) otherwise yep, same. BTW its not a 1980 loom if its 7 wire, it will be a 78/9 loom.

Dont know enough about electronics to argue the details. There may be more to it but if it is that easy and you can use a 7wire mag with a 6wire cdi it would be good info. Cant help thinking your missing something. Fkt if i know what though.

Why discard? You mean disregard and just leave it unconnected. Otherwise yep same ol yamaha. Aint broke etc,etc.

Don't worry about the running in rubbish. Your not going to stress an xv900 anytime soon. Just ride properly and your good. The engine will be better for it and your not worrying about throttle and gears and can concentrate on enjoying yourself.

To be fair if its just the tailpipe and you want to emulate the really naff louty broken/badly hacked scooteresc noise, and I mean 'noise' go right ahead. Its not like dep would have spent any time or money developing the exhaust is it.

Have to agree there. Hardly had a proper frost. Weather was colder at squires.

Otherwise?? You already did.

Litre of coolant not enough?, you didn't buy the ready mixed rip off did you?, that litre of antifreeze should make up 3, maybe 4 litres of actual coolant depending on the strength you need. I never ride in nut crushingly cold so could have a weak -5 strength. As the TDR only holds a dribble of coolant anyway I keep it at factory strength.

That oil pump system was finessed over 30 years, copied by everybody else and never bettered. (have you seen a Suzuki oil pump). Correct oil for fuel/rpm and adds oil on the overrun and with the throttle shut. No mess, no forgetting the oil, no over/ under dosing. No carrying a bottle of oil in your jacket, it just goes on. Leave well alone, messing with that pump has killed more DT's than any throttle abuse. Removing it is nuts.

Common sence for that question. Filters and such get changed often so not that big an issue. You have to balance any saving (gen stuff is often not much dearer than pattern). Against it failing.
