Ok guys, I need a bit of help

.....ive got a bit of a wobble as I accelerate at about 70mph like a small tank slap can ride through it but is spoiling my ride....new tyres approx 1000 miles ago.forks and rear spring on factory settings, iam 12st so about average.........iam not hot on suspension so need a bit of help, going to check head and wheel bearings tomorrow, is there anything else I should be looking at ?

The noggyfighter gets a proper wobble on at similar speeds when changing gear under load...like the front end is real light & i have to lean over the tank to stop it...but it is light though coz ive got no front end.......probably no good to you whatsoever then but jus sayin Red.

Cheers for your input mr nog.......your right.no foccing use to me whatsoever

......thats another difference between the 6 and thou, my 6 jumps about all over the place when pushing hard, the thous weight helps with stability which I like....dont like the wobble though........had another thought, wonder if ive lost a balance weight off the rim .......

red did nt you just do the rear wheel bearings? I would be checking round that area.!

red98 · « **Reply #4 on:** 17 May 2014, 08:06:39 pm »

Yes, new bearing in the week, I noticed the wobble before I changed the bearing, will go back and double check though

Check the wheel alignment. Check steering head bearings aren't too tight. Tyre pressures.

+ one for wheel alignment, plus check wheel balance. Another thing is try relaxing your grip on the bars, holding on too tight can cause similar reactions.

Cheers chaps, working tomorrow with time off mid-day, will see if I can get out to the garage and give the old girl a good going over

It could be the Plish and Romainian children you are running over in High Wycome,,or even Pakistanis

I had a real wobble/weave on today going to work this morning but it didn't get bad till I hit 130, I put it down to the Draggin' jeans flapping and my oversized back pack. I must admit I've not checked my tyre pressures for a month or 2.

The O ring on my right fork cap sprung a leak last year which I didn't fix for ages. Caused a very pronounced wobble when giving the bike full throttle at high speeds. Cured as soon as I topped up the fork oil & fitted a new O ring.

If the front's going light you could try jacking the back up or lowering the front 10 millimetres........ just a thought.

Check your weeble nut. I know for a fact that weebles wobble.

Living in Brum haven't a clue what you mean!

CRH · « **Reply #16 on:** 18 May 2014, 08:11:07 am »

firstly"..hope this isnt a sequel to the stuttering 6?...the wobbling thou"?...anyway,..i had the very same from my fjr and that turned out to be the head bearings"...but i also had a tank slap on my bandit 12 and that was down to the swinging arm bearings?...

....so i will go for rear suspension bearings fkd or siezed cus ime bound to be wrong!!!!!!!!!!!

red98 · « **Reply #17 on:** 18 May 2014, 12:59:53 pm »

Had a quick look......tyre pressures ok, wheel bearings ok, head bearings ok....wheel alignment slightly out on the marks, will use a long straight edge later to make sure......think I'll strip the rear end down to check swingarm bearings, I can clean and lube the shock link at the same time, not been done for a couple of years

......forks seam a bit hard and slow to bounce back so an oil change will be good.......tyres as good as new with no damage, only done about 1000 miles, wheel balance ok and all weights present........might make a start this afternoon, or as its a nice day get the mountain bikes out and take my son down the local park and raid the ice cream man.

Although an oil change will probably need doing mate, you'll need to proper clean the forks out as well - usually when oil goes off it goes thinner, so you lose damping, but I have heard of cases where the oil flow valves have got bunged up with crap if the oil hasn't been changed for a long time and need cleaning out!

Cheers joe...not done a fork re build for a long long time....will have to do some homework before I start

red98 · « **Reply #20 on:** 19 May 2014, 07:52:41 pm »

Nice evening for a bit of fazer fettling

.......took the swinging arm off...shock linkage all ok, a bit grubby but ok, will give it a clean and re-lube.....ive got a bit of play in the swinging arm bearings, not sure how much is acceptable but will change them to make sure...wemoto list a kit for £28 +p&p...makers name....slinky glide.....not heard of them before and not a term ive used for a very long time

Red...some geezers on here recommended me a bearing company, proper engineering place, i can concur that they are worthy....it was something like marksman, defo had like a target for its logo......anyhoo they were about 10 earth pounds each which is a good saving.

Ill try look for the receipt to save you endlessly searching through old threads.

Actually i may search "noggythenog" & swingarm & find the old post.

Just bear with me a little bit.
