Thank you! Yes, bar ends to fit just keep forgetting to order, doh! Good to get a look at the other side of the bike for a change. A lot quieter with the standard exhaust on as well

Have ordered the bar ends, spare time today so thought I would check and take for mot, difficult to start again! Checked all usual suspects and thought fuel starvation to blame, could get to start on choke but running off choke poor, decided to take carb out and found inlet rubber split below jubilee clip! Ordered from cmsl as fowlers had no stock,none on eBay either! 60 odd euros including postage, not pleased. To be expected for 29 yr old rubber parts I suppose, assume it split after initial reassembly as started and ran perfectly when first reassembled. At least I found the problem, just have to wait a week or so for delivery now

Only the ones with the additional intake silencer attachment will be left before long

@oldman It's just good we can still get them. Won't be long before they're discontinued.
Maybe I should buy another, still have the 89.to do

Like those fitted to late DTR / DT-X etc had a hole for another yeis type bottle to plug in and act I'm guessing as an intake silencer

Least it's not downstream of the carb so you won't do as much damage if it's not 100% sealed.

It is downstream of the carb, air drawn in rather than through carb hence starting difficulties, just as well found now, could have been much worse if I was caning it around, will try and post a pic hortly

I've explained it before, but probably poorly. Definitely research it.

Jesus! How did your guide dog get that carb in there and miss that massive split

I know what the YEIS does but I'm unsure if the second 'bottle' is a boost bottle and always assumed it was a modification by Yamaha to the older engine to either quieten it down more or improve emissions.

Split was not there when reassembled, ran fine at the time, been a few weeks since then waiting for wheels to be done, just old rubber I guess, could have gone anytime

Just had to Google that to check and you are correct

Still can't see a second bottle though. Only the normal bottle?

Yes I thought that might be the case due to having the dellorto rather than the mikuni carb.
If i could find a 200R engine I'd use the associated carb which I reckon is the same 28mm mikuni as the DTR
