stevie16v Posted March 25, 2009 Posted March 25, 2009 (edited) On sunday i came out of work, on the way home i reached a roundabout, sitting at 30mph, so clutch in, blip of throttle, down in to 2nd, Before i let the clutch out the back end lock up and kicked out. I tried restarting it, no oy, couldnt select a gear either. So pushed it off the road, got it started, and away i go again, except this time it feels as though the back end is wanting to push out, eg its feeling very light. I thought, right mmm puncture, checked it, nothing. Road at 30mph to the nearest garage, checked the pressures, fine. Ive ridden it home, about another 10miles. Went out on it this morning, and it still feels the same. Almost as tho it isn't connected to the road, went around a corner. Brake lightly for the junction and the back end wanted to go to my offside. I havent been going at speeds even close to what i have done before because of it. But its beginning to bug me now. So much so im a bit frightened to go out on the bike. Any suggestions?Oh, its an SV650 curvy Edited March 25, 2009 by stevie16v Quote
Korben Posted March 25, 2009 Posted March 25, 2009 Check chain tension, rear wheel alignment. Rear suspension might have knackered as well... Get it to a garage if you can't find it mate and get them to check. Quote
rennie Posted March 25, 2009 Posted March 25, 2009 That's worrying!!!!get it looked at quick!!!sounds like wheel has moved to me!I wouldn't ride it till I knew what it was Quote
stevie16v Posted March 25, 2009 Author Posted March 25, 2009 I've been out there. Checked the chain - about 2.5mm of play. alignment is spot on, nuts done up nice n tight. No play on the back wheel. When ive got the bike up on the paddock stand nd let it run on engine revs the chain isnt moving smoothly, it will go and have a wee "jerk" (excuse the expression) now n again, Its not sliping at the rear sprocket, im assuming thats because theres no weight on the rear wheel tho. Ive gave the pre-adjuster on the suspension a wee tweek around aswell. It was set at 6 which is its 2nd most stiffest, so dropped it to 4 which is the factory recommended Quote
Korben Posted March 25, 2009 Posted March 25, 2009 Check the manual mate, but I don't think that's anywhere near enough slack on the chain. Quote
stevie16v Posted March 25, 2009 Author Posted March 25, 2009 Ooops. my mistake. Its 25mm (2.5cm) which is within the 20-30mm stated in the book Quote
Guest Posted March 25, 2009 Posted March 25, 2009 prop the bike up on centre stand/paddock stand and turn the wheel by hand, you may have stuck links with will become evident when you turn the wheel, also take off the cover for the small front sprocket to see if you have all your teeth.. just cause the backs ok, the front could be shagd.. or out of true Quote
Guest Posted March 25, 2009 Posted March 25, 2009 it may sound daft but have you checked you rear caliper/brake, might be your pads have died, and are causing problems.. loosen the torque arm and drop the caliper to get a better look. Quote
stevie16v Posted March 25, 2009 Author Posted March 25, 2009 I had it up and gave it a once round, back seems fine. Havent taken the front off yet, do that tomorrow if i get a chance, getting a bit tight for heading to work now. Back brakes are fine, only a couple of weeks old including a full rebuild, checked to make sure it was working properly and it is. Went out a wee scoot there, and strangely, it feels fine. I leant over a fair bit as much as road conditions allowed and it was causing any problems. got what sounded like a backfire a couple of times tho. Once when accelerating uphill and once when i started the bike with a little bit of throttle Quote
rennie Posted March 25, 2009 Posted March 25, 2009 what sort of bike?is it a 2 stroke? partial siezure? Quote
Guest Posted March 25, 2009 Posted March 25, 2009 I would give the back wheel a thorough clean, it could be you spat out on diesel at the roundabout, and there could be some left on the tyre..just a thought Quote

I'll get some de-greaser on it and give it a good old clean Quote

I'll get some de-greaser on it and give it a good old clean dont use degreaser on a tyre the can leave a residue which will make it even more slippery or worse case attack the rubber nice warm soapy water i had a nice oily film on my rear tyre the other week i just boiled the kettle and poored it on the tyre Quote

Good job i checked this before i done anything Quote
stevie16v Posted March 28, 2009 Author Posted March 28, 2009 seems to have sorted itself. I went out ust a few miles yesterday and it was fine mmm strange. Im thinking there maybe was a film of something on it which has naturally worn off. Was very cautious with it yesterday taking it too work, but its fine no hassles. Thanks for the advice Quote
Korben Posted March 28, 2009 Posted March 28, 2009 Could all have been in your head mate... You have one weird moment (Diesel, wet white line, summat else) and you spend the next 100 miles thinking something is wrong with the bike..... Since my flat tyre last year I start to worry about the slightest twitch... Quote
stevie16v Posted March 28, 2009 Author Posted March 28, 2009 lol, yeah mate. So true. Paranoia i think its called! or erm, mentally instability. lol Quote
tony-1977 Posted March 28, 2009 Posted March 28, 2009 Ya being paranoid!! Same to me on my 125. Got a flat tyre on the back and the first I knew is when it stepped out and nearly chucked me on the deck. Now, every time I take a bend, it feels like it's gonna step out, but no matter how hard I push, it doesn't, and the wheel's aligned with the correct play in the chain and correct pressure Quote
stevie16v Posted March 28, 2009 Author Posted March 28, 2009 funny you should say that tony, happened to me on my wee sr 125, going around a sharp right, back end went right out from under me, managed to keep it up as it was just a light bike. Then it was going all over the road, it was the same feeling. But hey ho, all seems to be fine Quote
tony-1977 Posted March 28, 2009 Posted March 28, 2009 Not that you can push a 125 very hard anyway Just waiting on my test (7th April) then it's Bandit time Quote
