I chose to remove the protrusions from the throttle tube and the increase the inside diameter of the new grips tube. This I achieved by taping a small length of 60 grit abrasive about 50mm wide to the end of a short rod that I put in the chuck of my cordless drill. Do this gradually, stopping frequently to test the fit of the grip on the bar. How did you get on with removing the OE grip from the throttle tube? I had hells own job getting it off of the tube.
I have the original draft of the whole process I went through. If anyone wants I could re-post it here.
I gave up trying to get the grip off in one piece and resorted to a Stanley knife cut straight along the grip. I checked on Fowlers parts and found that the complete throttle tube and grip are less than £10 for the Speed 400 so it isn't worth the effort of trying to save them.
Just to update on this - no drips since and whilst the bikes only been out twice since replacing the hose/clips, today’s run was significantly longer so I’m happy enough.
Hi Baza, Yes on www.fowlersparts.co.uk the throttle tube complete with grip is listed as part number TA151017. The price is £9.91 plus p&p. This is only for the 400 series bikes made in India, copy of the relevant page attached. As an aside how on earth to Fowlers and Triumph justify £9.91 for the grip and throttle tube whereas the left hand rubber grip on its own is nigh on £20???!!
Just bought these:- https://eur.vevor.com/hydraulic-mot...k-1500-lbs-atv-dirt-bike-stand-p_010289643379 https://eur.vevor.com/hydraulic-mot...with-saddle-atv-lift-dirt-bike-p_010780317451 Supposed to arrive this coming weekend should sure help when have to take forks out to replace seals. Plezier
Bought an armoured motorcycle shirt at the Motorcycle Show, the usual dark grey check lumberjack type of thing.... for those (occasional!) warm sunny coffee ride-outs. Unfortunately it has been hidden away for my birthday in a few weeks!!
What an impressive petrol station that is, like back in the 70's in the UK. Stocks everything, racks of timing belts, ngk spark plugs, oil filters etc and absolutely tools galore. Miles bigger than it looks and crammed full, it must have at least x30 trolley jacks in all shapes and sizes. I couldn't resist so bought the wife a new 24mm impact socket, I think she loved it
I damaged my throttle tube while wrestling to get the Ultimate Addons heated grips on the throttle side. It basically cracked into pieces. It took me quite a long time to find them all and puzzle them back together. Finally I glued it all together with the super glue in the package and sanded the whole thing down to fit the grip. In the end the grip slid over the throttle tube. The heated grips work fine, but now the throttle does not snap back when I release it. Anybody experienced this as well? Did you replace the throttle tube? View attachment IMG_3908.JPG View attachment IMG_3911.JPG
Could you please explain step by step how to remove the throttle tube or point to a good video online?

I intend to buy a new throttle tube to fix this issue, but don't want to break the throttle body. Any advice is highly appreciated!
Maybe your repaired tube is binding inside a tad. Make sure its not the bar endmirror that's touching it first off. Then I would hone out the throttle tube inside with a bit of emory paper to give it some more clearance. Make sure its all clean and use lots of greace. You may have done it already (grandmother and sucking eggs etc.). Otherwise someone else might be able to help with advice on fitting heated grips over a new tube without destroying it again. Good luck.
These are are my recent purchases:- Motorcycle jacks should make changing the fork seals much easier. Fuel tap which it turns out is not only incorrect but it leaks far more than the old one that is being changed because it's drips the new one does not drip it just dribbles constantly so have bought another new one using a link a member over on Shadow.net gave me for one he says is of a good make.

There is a video on You Tube showing how to instal throttle spacers on the 400. That shows how to remove the throttle tube. Basically there are 2 screws at the base of the throttle assembly. These are removed and the throttle assembly comes apart. It is pegged into the bar so is rather stiff to release. Carefully separate the halves of the throttle and you will see a white plastic assembly with 2 small screws in it. This is the throttle potentiometer assembly (The ride by wire system). Remove these 2 screws and carefully lift the top half of the white plastic, this will release the throttle tube, (note how it fits back in the potentiometer. With the tube off the bike you can sand it without fear of damaging the delicate ride by wire parts. As the throttle tube is plastic you need to support it while sanding it and keep trial fitting the heated grip onto it. Make sure that it slides on without using too much force. Do not force it on!! When you have a nice snug fit then you can secure it with superglue. While sanding my throttle tube I clamped a metal bar in my vice and used that to support it. Sand carefully and make sure that you sand evenly around the tube so that it does not go oval! Best of luck!!
Thank you, the bar-end mirror is not touching so I will try to sand out the inside like you suggested ^_^
You must have been using considerable force to have damaged the throttle tube to that extent. First take the throttle tube off of the machine, two screws I think. Getting the OE grip off of the tube is a total pain as the adhesive that glues the grip to the tube is so tenacious it's untrue. It must have taken me a couple of hours, initially trying to preserve the grip and finally hacking it to pieces. Once the grip is off of the tube you will find that the throttle tube has protrusions from it to prevent grip slippage, total overkill with that glue. These protrusions need shaving off, but even with these removed you will find the internal diameter of the new grip is too small so you need to reduce the outside diameter of the throttle tube and/or increase the internal diameter of the new grip tube. I did a bit of both but in hindsight I would concentrate solely on the opening up the new grip. Just because it's easier and probably removes less material the way I did it. Which was to get a metal rod that was longer than the grip length and tape a 25mm wide strip of 60 grit abrasive to one end such that when the other end was tightened into the chuck of my cordless drill would give me a crude method of honing the inside diameter of the new grip tube which by inspection had more than enough material to accommodate the increase in internal diameter that was required. This honing process needs to be done with frequent test fits to ensure that you are not removing too much material and are concentrating your efforts where they are needed. I also found that I had to slightly open up the grip on the clutch side as well. I see that you went for the grips that had an external controller that had to be accommodated on the bars somewhere, whereas I went for the grips with the control all in the lefthand grip like the OE optional grips. Regarding your throttle not returning on release it can only be down to the two things mentioned by @Obijohnkenobe internal protrusions from your throttle tube reconstruction or the bar ends touching the end of the grip.
@Baza , thank you for your elaborate explanation! I did exactly that and lo and behold, smooth as a baby! About the force to break the throttle tube, I used a wrench to wrestle the grip off and should not have done that... Ended up cutting it off anyway. Live and learn ^_^ Thank you so much!
