I started out working the restricted rubbers a bit, keeping well clear of the indents each side - maybe 8-10% area reduction. Then I checked out a few more posts & compared the fiches for TB & TBS.
TBS cams, airbox, igniter etc. all the same. Just different exhaust....& Keihin carbs with their unrestricted rubbers & same jets, needles etc as the later TB that had Keihin....+14bhp TB to TBS ?...some smoke & mirrors going on here methinks
So figured I had to try those rubbers - they are from Mikuni carbed Tiger, I believe, part # T1240080
The results are excellent, midrange was good before tho' not as strong as low end & top end - now it's stonking torque right thru'
Interestingly, even tho' there was still a huge area difference between my 'worked' ones & the Tiger rubbers, no carb adjustments were needed.
I posted the full info. on the Proven Setups sticky.
It's quite possible the Dynojet parts don't make much difference & may not be worth the bucks. (My stock needles were worn tho') Very likely a 95 main jet, a notch or 2 richer on the needle, & 2 1/2 turn pilot screws will do the job....I would run that past the tech gurus here first tho'.
IMHO the .5 mm richer on the float heights is good for low revs high throttle pull.
Go for it
