Hi just wondering if anyone has any advise on this subject. I've just removed bent Renthal bars and replaced with the same (Renthal 755) new bars so now need to fit the end weights and as some of you probably know renthals don't come with threaded ends.
The old bars had the very heavy 307g original Fazer 1000 threaded weights in which seemed to've kept vibrations to a minimum although as the bikes new to me I have no frame of reference.
As I don't have a tap and die set big enough to thread the new bars my options seem to be either £41 for a tap and die set so I can use the old weights or £26 for these which are heavier than many others at 130g but less than half that of the oem ones

So if I go with the cheaper, quicker and better looking option with the R&G weights am I likely to feel more vibrations through the bars?
Cant you fill the bars with something? Lead shot, sand?
If you've got an engineering workshop near you, they'd be able to run a tap down the bar ends. I had the same dilemma, as after market weights that are as heavy as the Fazers are really expensive. Maybe you could hire a tap and die set. You need a 16mm tap @ 16 TPI (threads per inch). Initially I was told that it was necessary to run a 15mm drill bit down the bars, which have a 14mm inside diameter, before tapping them, but this has since been proved unnecessary. Good luck.

Any idea what I'd likely be charged for a engineering place to do it? If it's very little it would be a good idea but I wouldn't want to spend close to the value of buying my own set as at least then I've got the tool afterwards. Any thoughts on vibration changes with lighter end weights?
I live in the south where workshop time would be around £75 an hour, so expect a charge for half an hour, unless you know someone. I wouldn't have thought the average set would include a tap that large, but don't really know that as fact. That's why I suggested the possibility of hiring.

Thought it might be a bit pricey, I'm in the southwest so prices are probably as you say. The average set doesn't go as big as needed but this set https://rover.ebay.com/rover/0/0/0?mpre=...2083323352 does have a 16mm X 1.5mm tap which according to my measurements and what you say is the correct bit. It's £41 so about the same as half hour labour and although it's not going to be the best quality tool kit it should still do the job.
I've had renthal 758's on both my fazers and didn't have weights in either. I used the renthal plastic plugs (just thin inserts that cover the holes) and never had any issues with vibration, certainly not more than the standard ones.

If you're anywhere near Exeter I had a set of Renthals tapped out to take the OEM bar ends for £20.
My own experience is that the weight of the OEM bar ends does help prevent vibration felt through the bars, I could easily feel the difference between OEM and lightweight aftermarket which is why I got the bars tapped.

Thanks for the offer but I've just bought some lovely blue Renthals which I quite like. I'm sure Yamaha wouldn't have put such heavy ends on the bars for no reason and although the Renthals are longer so maybe don't need the same weight on the end I think I'd still prefer to have the OEM weights on there. Think I'm going to order the tap and die kit...
Oberon used to do very heavy stainless end weights that didn't need the bars tapped, the just bolt in with an expanding bolt setup.
Personally, I've tried various setups with no difference in vibration at all. I'm currently using R&G weights that screw into the standard bars and I can't feel any difference in vibration.

It must differ from bike to bike, i have fitted very light bar end mirrors to my thou & it meant that the bar end weights wouldn't re-fit but i have no problem with vibration.

If your talking about the R&G stainless with slider ends those were the ones I was looking at and the screw in ones are about 200g each compared to the 307g OEM which is closer than most others. Hopefully I'll tap out the Renthals properly and then at least I can change to the R&G weights at some point
Try riding the bike without the weights, I’ll be surprised if you notice much difference if at all! That’s been my experience, having said that some bikes vibrate more than others, I’m on my forth fazer and my second one vibrated like bast@rd! My current one is a beaut, really smooth.
Jim.
Can you not just buy a single tap the right size ? use a spanner to turn it, the bars don't need drilling out first. I got a mate nearby who had the right size, took him about 5 mins in a vice
My Renthals are tapped for the OEM bar ends & I find them to make quite a difference.
Having just fitted some Acerbis Dual Road hand guards I could not use the weights as well....makes a noticeable difference - also at high speeds the front end wobble seems worse without the weights.
I probably should've taken the bike out without them to see if it feels different but it keeps raining and I'm driving to Spain on it in May I just didn't feel like waiting.
Not sure if I could buy a single tap, didn't see any so I ordered the kit which should be with me tomorrow or the day after. Comfort is pretty much my only reason for upgrading to the 1000 from the 600 so I didn't want to take the chance as the vibration of the 600 was my biggest complaint and when your planning on driving from Bristol to the south of France in one day every little helps...
Too late if you've already ordered but...you can buy individual 16x1.5 carbon steel taps (taper, second or plug) from Tracy Tools for £10 each + postage.

Maybe of some use for others though?

Do you know for certain that the set that you have posted the link to has the M16 X 1.5mm tap in it?
The set appears to have 20 taps but in fact it looks like there are only 10 tap sizes as each of the 10 seems to have a taper/starter tap and a plug tap.
if it does have the size you want I think your option choice is better than buying a single tap, as you will have the whole set of tap and dies now for future use, get a broken stud at any point and you will be really glad you bought the set.
It is not something that you will use that often so a good spray with WD40 before they go in the drawer in the shed or garage will keep then in fine fettle.
