The airbox is designed to minimise induction noise. The effect is pretty restrictive on engine breathing and was designed with the very quiet original pipes. The three induction inhibitors are: Snorkel Filter Baffle. Pulling the snorkel increases the aperture. Just remember an over oiled filter can itself be restrictive. The internal baffle slots inside the airbox and is visible, filter removed. If you remove the snorkel you might as well remove the baffle. By way of comparison I have a fully gutted airbox, profiled snorkel plate and slightly more open exhausts than you with 128 main jets. MPG at 52-54 mpg is unaffected but mid range torque is appreciably improved.
Ok thanks Callum, I’ve now removed the baffle, but there’s not much point in reassembly until I’ve sorted the carbs. So back on the road,weather permitting,sometime next week.
You want to see the tiny numbers stamped on the brass jets. Since you are ‘going for it’ I would email TTP with your spec and they will send you the right jets for a tenner. https://www.triumphtwinpower.com/keihin-cvk-main-jets.php For an extra £60 you will have about the best total return on your mods https://www.triumphtwinpower.com/bo...ter-intake-cover-bellmouth-velocity-stack.php
Hello, I finally got round to a ride,down to the Dorset coast and back. I filled up when I got back and found I now have 53 mpg,which is a lot better than the 37 previously. The reason for the improvement was that the carbs needed balancing,they were way out,so that’s the next step in the right direction.The only problem is I think I need to have the ecu remapped to stop the popping and finalise the upgrades already done. I think I’ll wait to see if there’s any Black Friday or Christmas offers coming up . Also noticed an intermittent screeching sound coming from the speedo,so if anyone can tell me what to squirt or grease,I’d be grateful.
Hello, Sometime ago,Callumity sent a picture of an electrical connection under the tank.Unfortunately,my bike doesn’t have one,so the question is,where is the easiest place to make an accessory connection? I think someone mentioned the horn,but to be clear I’ve got heated grips and a usb to connect. I need it to work with the ignition,so I can’t connect straight onto the battery.. Thanks in advance.

Popping on the overrun is unburnt fuel burning off in the exhaust. You can’t really go leaner than 40 pilot jets with screws 2.5 to 2.75 out and maybe settle at that. Your igniter (not ECU) will have negligible bearing on the problem. Your screeching sound is very probably the drive cable not the instrument. https://www.wemoto.com/bikes/triump...33/01-06/picture/speedo_cable_by_slinky_glide
Thanks Callum, I’ve sprayed some lithium grease on the speedo cable(as per instructions)so we’ll see if this works otherwise a new cable. The popping may be resolved by some minor adjustments,so I’ll wait and see.Meanwhile,ordered some piggyback spade connectors for the heated grips and usb. Thanks for the cable info
I’ve just run the bike for ten minutes and noticed the header pipes glowing red hot. Is this normal?I’ve never seen this before,but it doesn’t seem right,perhaps somebody can throw some light on this. Thanks in advance.
Much more noticeable in the dark than daylight and especially if it has been sitting rather than in a cooling airstream. Do you still have air injection fitted? It exacerbates the problem by admitting oxygen for burning off residual unburnt fuel for emissions regs.
Thanks for the reply,the sai,or whatever it’s called has been removed,before I bought the bike.It sounds a bit spluttery,but like me,could probably do with a run. My shed was quite dark this afternoon,but I’ve never seen that on another bike.
as I needed to know the answer, not because I care where it was made, but just because I like to have the answer to an enigma, the European system, including the UK has the world manufacturer id as the first three letters, SMT for triumph, the 11th digit plant id only applies in north america, as far as I can tell it is impossible to say from the UK vin where your bike was built. SMTTJ9102G7xxxxxx
InExactly right! the European plant code is the 5th letter J for Jacknell Rd Hinckley T for Thailand Remember it is the assembly plant code and they ship parts in both directions.
I have the the same vin code as above,and somebody mentioned that the j is for Jacknell,so I believe this is a U.K. bike. Thanks for the replies.
Can anyone please tell me whether the pilot screws are slotted or Phillips or something else? I’ve tried taking a photo from underneath but it doesn’t show what they are.
The pilot jets themselves are slotted... The mixture adjuster screws are a D shaped head, and you can buy a tool: https://www.squaredeals-ltd.co.uk/d...keihin-carburettor-adjustment-tool-6617-p.asp Or apparently you can also get mixture thumb screw adjusters to replace the D head screws: https://www.squaredeals-ltd.co.uk/d...xture-thumb-screw-adjusters-3-only-3976-p.asp
Hello can anyone tell me what the banjo bolt is on the the front brake reservoir.Is it a m10 x 1.25 mm thread?
