MemberIthangyou Ian, like the idea of paring out the air filter hose to fit if unable to get a reducing collar in there. Hoping to get the carb up in the lathe to skim down to suit the manifold. A bit too much to take of by hand unless you are really desperate.
As for jets the carb came with two spare main & ditto pilot jets as part of the deal, for fine tuning.
Looking forward to give it a go. Regards.‘AAA Dummy
MemberHi Skorpy, glad your still here.
Yes to all you say, will be interesting if you do go ahead to hear your experiences. We don’t seem to have a Mikuni website in the UK. Motocarb imports them from the U.S.
Now look at the time of this message.
Never assume anything. I just woke up and the first thought that came into my head was that I hadn’t actually checked the sizes of the Mikuni. I mean they couldn’t possible be the same could they. Well I have just checked and amazingly they virtually are. The overall length is shorter by 6mm – good. The inlet dia is somewhat larger and will need a reducing collar to fit the filter hose and the outlet dia. is about ten thou bigger so will be able to use the existing inlet manifold, once bored out to match.
Interestingly the main obvious difference in the two carbs is the fuel enrichment chamber is at the engine end of the body so I’m hoping it will be more reactive.
Time for a cup of tea.
Goodnight folks.‘AAA Dummy
MemberHi all, Well Allens did have from what I’ve heard elsewhere. This was confirmed to me by not even replying to my enquiry.
I had however by searching the web come across Steve of Motocarb Liverpool who I subsequently found from another Forum was reckoned to be Ace and so it has proved, answering my enquiry from Saturday on Sunday would you believe.
Spoke to him on Monday and he is indeed a fair bloke. Ordered the carb there and then. Delivered 11.45am today – Tuesday !!! I have it here at my elbow.
Very nice it is too. Came set up for the Supa5 with spare jets and the connecting
rubber & clips and still had change from £200.00 ! Which I thought was pretty fair. I think that article must have been printed some time ago.
Now I just have to make up a mounting to the cylinder flange and sort out the air filter arrangement.
Any suggestions most welcome.
Hope the forgoing will be of help to the Brotherhood.
Cheers

MemberRight. Excellent, my cup runneth over as they used to say. Now to track “Allens” down. I expected the price has tripled in the intervene but if it gives as he says
it will be cheap at the price. I mean what use is a bike that will not start.
Thanks again. Rob.‘AAA Dummy
MemberStrewth ! ! !
In fact I’ll say it again STREWTH ! ! !
What a reply.
Must be a record breaker, many thanks.
I will now sit back and absorb.
I might be some time.

MemberVery interesting Ian. I live in hope that a Mikuni would improve the starting of my Supa5 which is covered up and languishing in the shed as I had virtually given up on it but after reading your post, hope springs anew !
So could I ask the model/size of your Mikuni and who the supplier was.
Cheers. Rob.
PS I fitted the Vape system to it some years ago and found it to be great bit of kit.
Not one kickback since.‘AAA Dummy
MemberKnowledgeable information helps in all manners.
Excellent much appreciated.‘AAA Dummy
MemberIt rained…. a lot! Ride deferred to a later date!

MemberI have the Mikuni carb and it is excellent as the bike came with a Mikuni I wanted to put it to the original which is a BVF, I tried the BVF and immediately changed it back to the Mikuni, I have run thousands of miles on the Mikuni and never felt I need the original BVF which is laid in a box SOMEWHERE.. You can fit the Mikuni without changing or looking for anything, it fits straight onto the intake and airbox.

MemberHmmmn. Did it start up ok with it. I would kinda be satisfied with that.
Are they on Ebay.

MemberThe shame of it all is that I really enjoy riding it, possibly my favourite bike.

MemberGood questo Skorpy. I would like to know as well.
My prob.with the standard carb is that it never gets the plug wet even. So I’m thinking that’s why its such a bugger to start. Done everything to it even new crank seals. Tried a brand new carb – just the same. I have kicked it till I’m blue in the face. One good
point it really has strengthened my right leg !
Oh for a regular strangler/choke
So whats your beef Skorpy.‘AAA Dummy
MemberHi
In the post above you mention removing the back tool box panel….. well, on my bike, I have a tight fitting seat, and underneath I can feel the void that is the tool kit space.
With the bike, I was supplied a ‘frame’ for the void and a lid with a lock that actually fits the bike.Can I just stanley knife out the fabric covering the void, then screw/bolt in the frame then fit the lid?
I really don’t want to wreck a perfectly fitted seat cover.
Or…… as usual, is it more complicated that that?

MemberI took it out for a 2nd ride yesterday and it was a lot better but still wanting to fade on no throttle. I didn’t mess about with any settings, I just wanted confirmation that my previous route (all 1 mile of it) wasn’t cursed, that it could and would drive forward without screaming, and that it wasn’t me imagining it all.
I think the manifold is a Chinese one too hence the ill fitting issue, so I also put some thread tape on there to bulk it out and to back up the O ring……
So far so good…. weather looks ok tomorrow so a bit further and see what happens………. Luckily I’m in the RAC so….. ‘ll keep you posted!
🙂

MemberHi Greg
Thanks for that, I certainly did, I twiddled everything!
Yesterday I untwiddled and reset everything to factory settings, also installing a rubber O ring between the carb and the inlet manifold as that too was slack and obviously would have been drawing air in. Since restarting it it does tick over much better but still isn’t consistent, it still stays a little too high when revved – so I’ll have another look at the tickover screw, and, it tends to die off once it starts warming up, any ideas on that one?
