Hi
has any one installed 36 VM round slide Carburettors on their  TR1 ?

ok since discovered that the 36v's are no go because of the left idle setup
im now fitting to right side 34vms which fit standard air box  pm
for jetting details

I'd say got for 115-120 mains, standard needle and about 15 or 17.5 pilots. (Jet sizes taken from a set of TM40ies (formerly on my TR1) and a TM36 on my XT500 - which all play roughly in the same ball park)

Hope this gives you a base to start from.

Cheers,
Greg

Hello, have you seen this page: Mikuni Vm. http://www.braigasen.com/Mikuni_jetting_chart_four_stroke.htm Have helped me a lot with other bikes (VM36-ls650)

after initial issues fitting the 36vms mainly because of the left side throttle  adjuster
i fitted 34vms and tuned and im quite happy
have yet to run them at high speed so will get back to u

34 sounds awfully small to me... but then a CV-carb will only give you a cross-sectional are of about 2/3 of its diameter, when flow is concerned, so with that considered, you may actually get away with it.

34 might bee wice? We speak about twin setup? THerese a lot of univerasl twin setup cables for xs and other bikes.  I have some experience with the VM round slide for Suzuki LS 650 single sylinder. I use a VM36 becauce, after others experience, a 38 does not give the right air velocity or vacume? The recommandation I have for LS 650 from people who have spent a lot of time on it says that the vm 36 will deliver enough for all kinds of motortuning. Cams, high comp etc.  If you look at the link -braigasen, the SR 500 single uses the vm 34 for exsample.

But only in stock form, they gain a lot, once you fit a TM36 flatslide...

Interesting. It is funny to learn about the mysterious world of carbs.  :) I mounted a O2 gauge permanently on my Ls650 to monitor especially on top speed. it helped me a lot. But I still use my ears to determine if the engine is rich or lean, and my hand to feel how hot the sylinder is.

Looking forward to hear more about the VM34 experience on top speed. Dont loose your licence ;D

Have a pair of 38 VM`s in a older race Project, first with 750 ccm - with a big hole downstairs, but runs good upstairs -
then with a original 1000 ccm engine and without air filter, runs well, but not so easy to handle like the Dellortos.
LLD 17,5 or 20, HD between 260 and 280.

Hello Sepp. I am very interested in the tuning you have done to your bikes. I guess you have told about them before, and I am beginner on TR1-forum, but maybee you have a link or something? I would like to learn more about what happens when you drop the frame air filter etc. I guess you move the power to higher revs? What can be achieved with other carbs, pod filter and a more open exhaust? I had a VTR1000 before and miss the pull from it.  :)

i've done a few rides with 34vms at high and low speeds though I'm still trying to fix a rich problem it runs great on the 34vms
