After recently fitting a tall boy seat to my Softy for better comfort to the lower back, & also allowing a bit extra leg room/ stretch out, than the old sundowner provided.  Now I've been experiencing pins & needles in my hands after 1/2 hr of riding. This was never a problem before now. 

Just wondering what might be causing this to happen. Is it because I'm sitting about 2" higher & maybe 1-2" further back, which might have increased the distance to reach my handle bars. 

I have Burleigh bars fitted but not 100% sure of rise height & pull back measurements. Grips are Kuryakyn "widow" type. Would going to a softer grip help in any way? Most times I wear "5" brand, leather gloves that have the moulded knuckle protectors in them.

Unfortunately I can't wind the throttle lock in any further than it can go, (so as to try give the right hand a little more circulation). The accelerator starts to decrease as soon as you release your hand off the grip.

Cheers for your help.

Make sure your gloves aren't too tight (when gripping) and look at a throttle rocker for longer rides so you can stretch out your fingers occasionally.

if you have only changed the seat and you are now higher, I would say the handle bars could now have your hands on the wrong angle, you will have to move them towards the front a little. I would loosen the the bars and set it to were you are comphy
I am no expert but

Change to seat back and see if it stops...

kuryakyn "ISO" grips are an anti-vibration type grip but sounds like changing your seat has also changed your posture on the bike putting more weight on your hands.

Maybe try some finger-less type gloves as more weight on your hands stretches full fingered gloves tighter around the tips, wont cost much to find out- Fleabay have em for about 8 or 11 bucks I think.. "rawhide" is the brand I use, they have a half dozen different styles and come in heavier leather or thinner softer goatskin leather, the goat ones tear after a while being so thin. The regular cow hide ones have lasted me a long time after buying the thin ones first. Worth a try I reckon

A bit ironic how the seat has given you more comfort in one area and taken it from another. Bit of a cunt that, cause I also put custom solo seats on my bikes so it can be a costly mod to find it just not quite right.. anyway cheers man , have a great chrissy

Pins and needles in your hands can be caused by pressure on discs in your upper back around c5 and c6 . I would go with the suggestion of re-fitting the old seat for a week , then if if it goes away changing your bar set up for the new seat .

I get it in my right thumb as well I've only been riding my softail for two weeks. I read somewhere that it's the bars sitting to low. If your seat is higher then the old one that might be the problem.

A riding mate used to get pins and needle sensations whilst riding for a lot of years and ended up being carpel tunnel syndrome. He had both wrists operated on at the same time and after a coupla months was as good as new and no more dramas.
But also if you are sitting further back, have a look to make sure your jacket is not putting added pressure on your arms just up from your armpits. There are major arteries in that area and putting undue pressure there can cause numbness in the hand and arm.

I was getting the same thing when riding for a while. Couldn't figure out why it only happened occasionally. Turned out it was because I was wearing a jumper under my jacket and it was pinching under my armpit causing loss of circulation. Your riding position may have affected this for you too??

Yep, pinching something because of the changed rider position is probably the cause. If I ride a sports bike and lean forward with the jacket tight under my arms I get it real quick. Only if I ride with a jumper under my jacket on the HD though. I also get it after a couple of hours wearing gloves but not really all that bad.

Well, howd ya go with it 06softail.
Whats the outcome with it champion
Its got my interest, curious to hear the verdict on this one

Pins and needles are generally attributed to circulation issues.

My suggestion would be to lose the jacket, lose the gloves, and go for a cruise on a sunny day to see if you still have the issue before pissing around with the bike.

If you're an older bastard like myself who smokes, drinks, gets amongst the cholesterol and generally abuses his body, then your circulation wont be what it was, and little things like pressure points will tend to show up much more.

Generally on a bike going faster means more wind resistance on your chest, which in turn takes body weight and pressue OFF your wrists and palms.....so roll on the horses to see if that helps. If it does you have too much body weight too far forwards with the higher seat, and need to lift the bars to compensate, or in future you instead need to ride it like you stole it!.

could the backpack be contributing to your problem also?
don't know about the throttle lock but im sure someone will. (Ive never used mine, but it works)
a lot of the aftermarket chrome switch housings come with new throttle lock assembly's, if you don't have chrome housings already. Might kill 2 birds- practical function and bling at the same time

Ahh yes, I do remember...good to talk to you again.

My bike was shagged and required a top end rebuild after that day...no wonder it was pissing oil and I was having trouble keeping up.

Your body's not as decrepid as mine, so I wouldn't bother trying the jacket and glove thing.

As much as it's gonna be an inconvenience and cost a few bucks, I recon you need to lift the bars to get back the riding position and get some body weight off your hands.

I look forward to another local run, but this time on a bike which works.

Please bear in mind though, I have no expertise in the subject, so before taking my unqualified word for it and forking out dollars, take in some opinions from qualified people ehp DO know what they're on about.

Have you swapped the seat back and been for a ride to see if it still happens???

Yeh I'm looking at bigger risers for my fatbob for the exact same reason. Mines not too bad but I noticed on the bob I lean a lot more foward then on my old bike. Love the look of the bars tho so I'm just gonna swap out the risers for a taller biltwell set.
